Acid Reflux or Something More? When to Consider a Gastroscopy

Acid Reflux or Something More? When to Consider a Gastroscopy

by | Nov 25, 2025 | Gastroenterology


Acid reflux is one of the most common digestive complaints today. Almost everyone has experienced that unmistakable burning feeling behind the breastbone after a heavy meal, late-night snack, or stressful day. While most cases of acid reflux are harmless and easily managed with lifestyle changes or over-the-counter medication, persistent or severe symptoms may point to something more serious.

For many patients, the biggest question is: How do I know when it’s just heartburn—and when it’s time to consider a gastroscopy?

Understanding the difference can make a major impact on your digestive health, early diagnosis, and treatment outcomes.

This article explores the signs, risks, and red flags of chronic reflux, and explains when a gastroscopy—performed by specialists like Dr. Deetlefs, who has extensive experience in gastroscopy treatments—may be recommended.

 

What Is Acid Reflux?

 

Acid reflux occurs when stomach acid flows upward into the oesophagus (food pipe). This happens when the lower oesophageal sphincter (LES), a small ring of muscle that acts like a valve, weakens or relaxes at the wrong time.

Common triggers include:

  • Fatty, spicy, or acidic foods
  • Alcohol and caffeine
  • Smoking
  • Obesity
  • Eating too late at night
  • Stress
  • Certain medications

Most people experience reflux occasionally, and it usually settles quickly. But when it becomes frequent, persists for weeks, or interferes with daily life, it may indicate gastro-oesophageal reflux disease, also known as GERD.

 

Symptoms of Acid Reflux

 

Not every patient experiences reflux the same way. Classic and common symptoms include:

  • Burning sensation in the chest (heartburn)
  • Sour taste at the back of the throat
  • Regurgitation of food or fluid
  • Bloating
  • Belching
  • Chronic cough
  • Hoarse voice
  • Difficulty swallowing

These symptoms can range from mild to severe. Importantly, reflux symptoms should respond to simple interventions—like diet changes, weight management, or over-the-counter antacids. When they don’t, it’s time to investigate further.

symptoms_of_acid_reflux

 

When It Might Be More Than Acid Reflux

 

While reflux is common, some symptoms may suggest a more serious underlying condition. These include:

  1. Persistent or Worsening Symptoms

If your reflux symptoms continue for several weeks despite medication or lifestyle changes, it may signal complications such as:

  • Inflammation of the oesophagus (oesophagitis)
  • Narrowing (strictures)
  • Barrett’s oesophagus

These conditions cannot be confirmed without a gastroscopy.

  1. Pain That Mimics Heart Disease

Chest pain is a symptom that doctors take extremely seriously. While reflux can cause chest discomfort, it’s important to seek urgent medical evaluation to rule out cardiac causes.

Once heart disease is excluded, persistent chest discomfort may need investigation through gastroscopy.

  1. Difficulty Swallowing (Dysphagia)

A feeling that food is getting “stuck” or slow to pass down the oesophagus is a major red flag. This can be caused by inflammation, scarring, or growths within the oesophagus.

  1. Unexplained Weight Loss

Losing weight unintentionally may indicate a more serious problem in the upper digestive tract. A gastroscopy helps detect structural problems and early signs of disease.

  1. Vomiting, Especially With Blood

Regular vomiting or vomiting that contains blood, requires immediate investigation. These symptoms suggest irritation or bleeding somewhere in the upper gastrointestinal tract.

  1. Anemia

If a patient develops iron-deficiency anaemia, it may be due to chronic bleeding from the stomach or oesophagus. A gastroscopy helps identify the source.

 

What is a Gastroscopy?

 

A gastroscopy, also known as an upper endoscopy, is a minimally invasive procedure that allows a specialist to examine the oesophagus, stomach, and the first part of the small intestine (duodenum).

It is performed using a thin, flexible tube with a light and camera at the end. The images are projected onto a screen so the specialist can look for:

  • Inflammation
  • Ulcers
  • Abnormal growths
  • Bleeding
  • Structural problems
  • Infection (including Helicobacter pylori)

Dr. Deetlefs, who specialises in gastroscopy treatments, uses this advanced diagnostic tool to accurately identify the causes of persistent reflux or other upper-GI symptoms, ensuring patients receive the correct diagnosis and treatment plan.

gastrocopy_procedure_adic_reflux

Why a Gastroscopy May Be Recommended

 

A gastroscopy is not typically the first step in evaluating reflux. However, it becomes essential when symptoms suggest complications or an underlying disease.

Here are the main reasons your doctor—such as Dr. Deetlefs—may advise a gastroscopy:

  1. Your Reflux Is Long-Standing

Patients with reflux lasting five years or more, especially those over 50 or with risk factors like obesity and smoking, may require screening for Barrett’s oesophagus, a condition linked to chronic acid exposure.

  1. Symptoms Do Not Respond to Treatment

When antacids, proton pump inhibitors (PPIs), or lifestyle changes don’t provide relief, gastroscopy helps identify why.

  1. Alarm Symptoms Are Present

These include:

  • Difficulty swallowing
  • Vomiting
  • Bleeding
  • Persistent pain
  • Weight loss

Alarm symptoms are never ignored and require prompt investigation.

  1. You Have a Family History of Oesophageal or Stomach Cancer

In such cases, early screening is important, especially if reflux is present.

  1. To Diagnose or Confirm Hiatal Hernia

A hiatal hernia is a common contributor to reflux. A gastroscopy allows the specialist to assess its severity.

 

 

What Conditions Can a Gastroscopy Detect?

 

Gastroscopy is one of the most valuable tools in digestive health because it allows direct visualisation—and often biopsy—of tissues.

Some conditions it helps diagnose include:

  1. Oesophagitis

Inflammation caused by acid damage.
If left untreated, it can progress to scarring and strictures.

  1. Barrett’s Oesophagus

A change in the lining of the oesophagus due to chronic reflux.
Although Barrett’s oesophagus does not cause symptoms on its own, it increases the risk of oesophageal cancer. Early detection is critical.

  1. Peptic Ulcers

Ulcers can occur in the stomach or duodenum and may cause pain, bleeding, or anaemia.

  1. Hiatal Hernia

A structural issue where part of the stomach pushes upward through the diaphragm. Gastroscopy helps assess its impact on reflux.

  1. Gastritis

Inflammation of the stomach lining, sometimes caused by medications or infection.

  1. H. pylori Infection

A common bacterial infection linked to ulcers, gastritis, and even stomach cancer.

  1. Cancers of the Upper GI Tract

Although not common, early detection through gastroscopy dramatically improves treatment outcomes.

 

 

What to Expect During a Gastroscopy

 

Many patients feel anxious before their first gastroscopy, but the procedure is quick, safe, and done under sedation to ensure comfort.

Here is what typically happens:

Before the Procedure

  • You’ll be asked not to eat or drink for 6–8 hours.
  • Your medical team will discuss any medications you’re taking.

During the Procedure

  • You’ll receive sedation so you remain relaxed and comfortable.
  • A thin endoscope is gently guided through the mouth and down the oesophagus.
  • The specialist examines the lining of the oesophagus, stomach, and duodenum.
  • Small tissue samples (biopsies) may be taken if needed. Biopsies are painless.

After the Procedure

  • You’ll rest briefly while the sedation wears off.
  • Most patients can go home the same day.
  • Your doctor will explain the findings and discuss next steps.

As an experienced endoscopist, Dr. Deetlefs ensures that patients receive safe, thorough, and compassionate care throughout the process.

 

Why Early Investigation Matters

 

Ignoring symptoms, especially persistent reflux, can lead to long-term complications. Early gastroscopy can:

  • Prevent progression to more serious disease
  • Detect conditions at their earliest and most treatable stage
  • Provide peace of mind
  • Guide the correct treatment pathway
  • Reduce the risk of complications like strictures or bleeding
  • Screen for conditions like Barrett’s oesophagus

When in doubt, it is always safer to investigate.

IBS vs. IBD: Understanding the Differences and Treatment Options

IBS vs. IBD: Understanding the Differences and Treatment Options

by | Nov 15, 2025 | Colonoscopy, Gut Health

 

Digestive discomfort is common, but when abdominal pain, bloating, or changes in bowel habits persist, many patients start to wonder what’s really going on. Two of the most common — and often confused — digestive disorders are Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD).

Although their symptoms may overlap, these are very different conditions with distinct causes, diagnostic processes, and treatment approaches. Understanding these differences is key to finding effective relief — and knowing when to see a gastroenterologist like Dr. Eduan Deetlefs in Cape Town for expert evaluation and care.

 

What Is IBS?

Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder, meaning there’s no visible inflammation or damage to the digestive tract. Instead, IBS involves a disturbance in how the gut functions, often related to hypersensitivity of the intestines or abnormal muscle contractions.

IBS affects the large intestine (colon) and can cause chronic digestive symptoms that fluctuate in intensity. It’s one of the most common GI conditions worldwide, affecting both men and women, often beginning in early adulthood.

Common Symptoms of IBS:

  • Recurrent abdominal pain or cramping
  • Bloating or excessive gas
  • Changes in bowel habits — diarrhea, constipation, or alternating between both
  • A feeling of incomplete bowel emptying
  • Mucus in the stool
  • Relief of pain after a bowel movement

IBS symptoms are often triggered by diet, stress, or hormonal changes, and they may come and go over time. Importantly, IBS does not cause intestinal damage, bleeding, or weight loss — these signs usually indicate another condition.

 

ibs_ibd_symptoms

 What Is IBD?

Inflammatory Bowel Disease (IBD) refers to chronic, immune-mediated inflammation of the digestive tract. Unlike IBS, IBD causes visible damage to the intestinal lining, which can lead to serious complications if untreated.

There are two main types of IBD:

  1. Crohn’s Disease – can affect any part of the digestive tract from the mouth to the anus, often in “patchy” segments.
  2. Ulcerative Colitis – affects only the colon and rectum, causing continuous inflammation and ulcers in the intestinal lining.

IBD is an autoimmune condition, meaning the body’s immune system mistakenly attacks healthy cells in the gut, causing inflammation and tissue injury.

ibd_symptoms


Common Symptoms of IBD:

  • Persistent diarrhea (sometimes with blood or mucus)
  • Abdominal pain and cramping
  • Unintended weight loss
  • Fatigue
  • Loss of appetite
  • Blood in the stool
  • Fever or joint pain in severe flare-ups

Because IBD causes real inflammation, it can lead to complications such as intestinal strictures, fistulas, abscesses, or increased risk of colon cancer — making early diagnosis and treatment essential.

🔍 IBS vs. IBD: Key Differences at a Glance

 

Feature IBS (Irritable Bowel Syndrome) IBD (Inflammatory Bowel Disease)
Type of condition Functional disorder (no visible damage) Autoimmune inflammatory disease
Affected areas Large intestine (colon) Any part of GI tract (Crohn’s) or colon/rectum (Ulcerative Colitis)
Cause Gut hypersensitivity, stress, diet, hormonal factors Immune system attacking intestinal tissue
Inflammation present? ❌ No ✅ Yes
Symptoms Bloating, pain, diarrhea/constipation, mucus Bloody diarrhea, pain, fatigue, weight loss
Complications None (does not cause damage) Intestinal damage, strictures, cancer risk
Diagnosis Clinical history, exclusion of other diseases Colonoscopy, biopsies, blood/stool tests, imaging
Treatment goal Symptom management Inflammation control and remission
Seriousness Chronic but not life-threatening Can be serious or life-threatening if untreated

🧠 Understanding the Causes

 

Causes of IBS

The exact cause of IBS is not fully understood, but several factors are thought to contribute:

  • Abnormal gut motility: Muscles in the intestines contract too quickly or too slowly.
  • Visceral hypersensitivity: The nerves in the gut are overly sensitive to stretching or movement.
  • Gut-brain axis dysfunction: Stress and anxiety can directly affect gut function through nerve signals.
  • Dietary triggers: Fatty foods, caffeine, dairy, and artificial sweeteners may worsen symptoms.
  • Post-infectious IBS: Some people develop IBS after a bacterial or viral infection.

 

Causes of IBD

IBD is more complex, involving a mix of immune, genetic, and environmental factors:

  • Immune system dysfunction: The body mistakenly attacks the intestinal lining.
  • Genetics: A family history of IBD increases risk.
  • Gut microbiome imbalance: Certain bacteria may trigger inflammation.
  • Environmental factors: Smoking, diet, and infections may contribute.

ibs_ibd_triggers

🧪 Diagnosing IBS vs. IBD

Because their symptoms overlap, a proper diagnosis is essential.

Diagnosing IBS

IBS is usually diagnosed by excluding other conditions. Gastroenterologists use the Rome IV Criteria, which include:

  • Abdominal pain at least once per week for the last 3 months
  • Pain related to bowel movements or changes in stool frequency/consistency

Tests may include:

  • Blood tests to rule out celiac disease or anemia
  • Stool tests to check for inflammation
  • Colonoscopy (if red-flag symptoms like bleeding or weight loss are present)

 

Diagnosing IBD

IBD requires more direct evaluation of inflammation and damage. Dr. Deetlefs may recommend:

  • Colonoscopy or gastroscopy – to view and biopsy inflamed tissue
  • Blood tests – checking for anemia, infection, or inflammation markers
  • Stool tests (calprotectin or lactoferrin) – to measure intestinal inflammation
  • Imaging (CT or MRI enterography) – to visualize small bowel involvement in Crohn’s disease

ibs_diagnosis

💊 Treatment Options for IBS and IBD

 

IBS Treatment

Because IBS is functional, treatment focuses on symptom control and lifestyle modification.

  1. Dietary Management
  • Low-FODMAP diet: Eliminating fermentable carbohydrates that cause gas and bloating.
  • High-fiber diet: Helps relieve constipation (for IBS-C).
  • Avoiding trigger foods: Caffeine, spicy food, alcohol, and processed meals.
  1. Stress and Lifestyle
  • Regular exercise and mindfulness can reduce gut-brain tension.
  • Good sleep hygiene and stress reduction techniques (yoga, deep breathing).
  1. Medications
  • Antispasmodics: Reduce cramping.
  • Antidiarrheals or laxatives: For bowel habit regulation.
  • Low-dose antidepressants: Modulate gut nerve sensitivity.
  • Probiotics: Support healthy gut flora.

IBD Treatment

IBD requires a more targeted medical approach to reduce inflammation and prevent long-term damage.

  1. Anti-Inflammatory Medications
  • Aminosalicylates (5-ASA): Reduce inflammation in the colon.
  • Corticosteroids: Used short-term for acute flare-ups.
  1. Immune System Suppressors
  • Azathioprine or methotrexate: Help reduce immune overactivity.
  1. Biologic Therapies
  • Advanced treatments that target specific inflammatory pathways (e.g., TNF inhibitors, integrin blockers).
  • Biologics have revolutionized IBD management, offering long-term remission and mucosal healing.
  1. Nutritional Support
  • Ensures patients maintain healthy weight and nutrient levels during flare-ups.
  1. Endoscopic or Surgical Interventions
  • Endoscopic dilatation may treat strictures caused by Crohn’s disease.
  • Surgery may be necessary for severe cases or complications such as bowel obstruction or perforation.

Summer-Proof Your Gut: How to Keep Your Digestive System Healthy in the Heat

Summer-Proof Your Gut: How to Keep Your Digestive System Healthy in the Heat

by | Oct 30, 2025 | Gut Health

As the Cape Town summer arrives, life moves outdoors — beach days, braais, and sunny afternoons are part of the season’s charm. But while you’re enjoying the warmth, your digestive system may be working overtime. The combination of heat, dehydration, dietary indulgence, and lifestyle changes can disrupt your gut’s delicate balance — leading to bloating, constipation, or flare-ups of chronic conditions such as IBS (Irritable Bowel Syndrome), Crohn’s disease, or ulcerative colitis.

The good news? With the right care and a few seasonal adjustments, you can keep your gut happy and healthy all summer long. Here’s how.

 

Why Summer Can Disrupt Your Gut

 

1. Dehydration and Digestion

 

Cape Town’s warm weather increases fluid loss through sweat. When your body lacks hydration, the digestive process slows down — the colon absorbs extra water from stool, leading to constipation, bloating, and sluggish digestion.

If you live with inflammatory bowel disease (IBD), dehydration can worsen symptoms and strain the kidneys due to electrolyte imbalance, especially during bouts of diarrhea or vomiting.

💧 Gut tip: Sip water consistently throughout the day — not just when thirsty. Carry a reusable water bottle and include electrolyte-rich drinks or coconut water when active or spending time outdoors.

 

gut_health_in_summer

 

2. Heat, Stress, and the Gut-Brain Connection

Summer brings relaxation — but it can also bring stressors: travel, disrupted routines, and late nights. These factors, combined with physical stress from the heat, can affect the gut-brain axis — the powerful link between your digestive system and your nervous system.

For those with IBS or IBD, this connection is especially sensitive. Stress may lead to abdominal pain, urgency, or diarrhea.

🧘 Gut tip: Manage summer stress with mindfulness, gentle yoga, or evening walks along Cape Town’s promenade. Keeping a consistent routine and sleep schedule helps support digestion and mental well-being.

 

3. Changes in Eating Habits

 

Let’s face it — summer is a time of indulgence. From braai feasts and spicy sauces to cold beers and fizzy sodas, many summer staples can irritate the digestive tract. These foods increase stomach acid, slow down digestion, and can trigger reflux, bloating, or discomfort.

gut_health_in_summer_heat

 

🥗 What to Eat for a Happy Summer Gut

Cape Town’s summer markets are packed with fresh, local produce — perfect for supporting digestive health. Choosing gut-friendly foods can help balance your microbiome, reduce inflammation, and keep your energy up. 

 

🍉 1. Hydrating Fruits and Vegetables

 

Fruits like watermelon, cucumber, oranges, and strawberries are rich in water and electrolytes. Pair them with leafy greens such as spinach or kale for a fiber boost that keeps digestion regular.

 

🥛 2. Fermented and Probiotic-Rich Foods

 

Include yogurt, kefir, sauerkraut, or kimchi in your meals. These probiotic-rich foods feed healthy gut bacteria, supporting digestion and reducing bloating — especially useful when your diet changes during travel or holidays.

 

🌾 3. Whole Grains and Fiber

 

Oats, quinoa, and whole-grain bread act like a broom for your digestive tract, helping prevent constipation and supporting healthy gut flora. Increase fiber gradually and always drink enough water alongside it.

 

🐟 4. Lean Proteins and Omega-3s

 

Enjoy Cape Town’s coastal bounty — salmon, sardines, and tuna are excellent summer options. These fish are high in omega-3 fatty acids, which help reduce gut inflammation and support heart health.

 

healthy_eating_in_summer_gut

 

🚫 Summer Gut Triggers to Watch Out For

🍺 1. Alcohol and Fizzy Drinks

 

Alcohol can irritate the stomach lining and worsen reflux or diarrhea. Fizzy drinks add excess gas, leading to bloating.

Better choice: Alternate drinks with water or soda water. Try refreshing, low-acid options like gin with cucumber, or enjoy a mocktail made with coconut water and fresh fruit.

 

🌶️ 2. Spicy and Fried Foods

 

Heavy sauces, fried meats, and spicy marinades can trigger acid reflux and indigestion, particularly in those with GERD or IBS.

Better choice: Opt for grilled or baked meals, seasoned with herbs like basil, mint, or coriander for flavor without the burn.

 

🍤 3. Unhygienic Food Handling

 

Hot weather accelerates bacterial growth. Leaving food out during picnics or braais can cause food poisoning — a quick route to gut distress or flare-ups in sensitive individuals.

Better choice: Refrigerate leftovers promptly, wash produce thoroughly and avoid undercooked seafood or meat. 

 

💧 Hydration: The Unsung Hero of Gut Health

Water plays a vital role in digestion — it helps break down food, absorb nutrients, and move waste through the intestines. In summer, dehydration is one of the biggest threats to digestive comfort.

Hydration Tips:

  • Start your morning with a glass of water before coffee.
  • Snack on hydrating foods like cucumber or watermelon.
  • Infuse your water with lemon, mint, or berries for flavor.
  • Limit caffeine and alcohol, both of which dehydrate.
  • Sip water regularly throughout the day, especially when outdoors.

Aim for 6–8 glasses daily, and more if you’re active or sweating.

🌿 Lifestyle Habits for a Healthy Summer Gut

🕒 1. Keep a Consistent Routine

 

Even during holidays, try to eat meals at regular times. Erratic eating can lead to bloating and indigestion.

🏖️ 2. Stay Active — Safely

 

Exercise keeps your digestion moving, but overexerting in the heat can backfire. Choose morning or evening workouts, swimming, or yoga to stay active without overheating.

 

😴 3. Prioritize Rest and Stress Management

 

Poor sleep and mental fatigue can heighten gut sensitivity. Set aside time to relax, read, or meditate — your gut and mind will thank you.

 

✈️ 4. Protect Your Gut While Traveling

 

Summer holidays often mean new foods and environments. To avoid traveller’s tummy:

  • Wash your hands before eating.
  • Stick to bottled or purified water.
  • Avoid raw or street food if hygiene is uncertain.
  • Pack your regular medication and probiotics.

⚠️ When to See a Gastroenterologist

Occasional digestive discomfort is common, but persistent symptoms can indicate an underlying condition.
Book an appointment with a gastroenterologist if you experience:

  • Frequent abdominal pain or cramps
  • Blood in stool
  • Ongoing diarrhea or constipation
  • Unexplained weight loss
  • Severe heartburn or reflux

Early diagnosis and professional care can prevent complications and help you enjoy a symptom-free summer.

Colon Cancer: Early Detection and Prevention Through Regular Screening

Colon Cancer: Early Detection and Prevention Through Regular Screening

by | Oct 15, 2025 | Cancer Screening, Colonoscopy

 

Colon cancer, also known as colorectal cancer when it involves both the colon and rectum, remains one of the most common yet preventable cancers globally. Through advances in medical technology—particularly colonoscopy screening—the early detection and prevention of colon cancer have never been more achievable.

Regular colonoscopy examinations not only detect cancer in its earliest, most treatable stages but can also prevent it entirely by removing precancerous growths. For patients seeking expert care in South Africa, Dr. Eduard Deetlefs, a leading gastroenterologist and colonoscopy specialist in Cape Town, provides comprehensive, patient-focused digestive health services to safeguard your long-term wellbeing.

Understanding Colon Cancer

The colon, or large intestine, forms part of the digestive tract responsible for processing waste and absorbing water and electrolytes. Colon cancer typically begins as small, benign growths called polyps that form on the lining of the colon.

Over time, certain polyps—particularly adenomatous polyps—can undergo cellular changes that transform them into cancerous tumors. Because this process develops slowly, often over many years, routine colon cancer screening provides a critical opportunity for early intervention and prevention.

colon_cancer_prevention

 

Who Is at Risk?

While anyone can develop colon cancer, certain factors increase the likelihood:

  • Age: Risk rises significantly after the age of 50, though cases in adults under 45 are becoming more frequent.
  • Family History: Having a close relative with colon cancer or advanced polyps increases personal risk.
  • Genetic Syndromes: Conditions such as Lynch syndrome or familial adenomatous polyposis (FAP) substantially elevate risk.
  • Lifestyle Factors: Diets high in red or processed meats, obesity, smoking, alcohol use, and lack of exercise are all linked to higher risk.
  • Inflammatory Bowel Disease (IBD): Long-standing Crohn’s disease or ulcerative colitis increase colon cancer risk.
  • Type 2 Diabetes: Metabolic and hormonal factors in diabetes may also contribute to higher risk.

Understanding and managing these risk factors—combined with routine colonoscopy screening—can significantly reduce your chances of developing colon cancer.

 

Recognizing the Symptoms

In its early stages, colon cancer often develops silently, showing no symptoms. As the disease advances, common warning signs include:

  • Persistent changes in bowel habits, such as constipation, diarrhea, or narrow stools
  • Blood in the stool or rectal bleeding
  • Unexplained fatigue or weakness
  • Cramping, bloating, or abdominal pain
  • Unexplained weight loss
  • A feeling that the bowel does not empty completely

Because these symptoms can resemble other gastrointestinal conditions, timely medical evaluation by a gastroenterologist is essential.

 

Colonoscopy: The Gold Standard for Detection and Prevention

Among all available screening tests, colonoscopy remains the most accurate and effective method for detecting colon cancer and its precursors. This minimally invasive procedure allows a colonoscopy specialist to inspect the entire colon and rectum using a thin, flexible tube with a camera.

What Happens During a Colonoscopy

  • Preparation: Before the procedure, patients follow a bowel-cleansing preparation to ensure clear visibility.
  • Procedure: Under mild sedation, the doctor gently advances the colonoscope through the colon to examine the lining.
  • Polyp Removal: If any polyps or abnormal tissue are found, they can be removed immediately and sent for analysis.

Because colonoscopy allows both diagnosis and treatment during the same procedure, it’s not only a screening tool but a powerful method of cancer prevention.

colon_cancer_screening_colonoscopy

Other Screening Options

While colonoscopy is the most comprehensive test, other screening options are available for some individuals:

  • Fecal Immunochemical Test (FIT): Detects microscopic blood in the stool.
  • Fecal Occult Blood Test (FOBT): Identifies hidden blood but requires dietary restrictions.
  • Stool DNA Tests (e.g., Cologuard®): Look for genetic changes linked to colon cancer.
  • CT Colonography: A “virtual colonoscopy” using advanced imaging technology.

However, unlike these tests, colonoscopy provides the advantage of immediate detection and removal of precancerous polyps, making it the preferred option for most patients.

When to Begin Screening

The American Cancer Society and global gastroenterology guidelines recommend:

  • Average-Risk Adults: Begin colon cancer screening at age 45.
  • High-Risk Individuals: Those with family history, genetic conditions, or IBD should start earlier, often by age 40 or sooner, as advised by their doctor.

If no abnormalities are found, colonoscopy should be repeated every 10 years. If polyps are discovered, follow-up may be recommended in 3 to 5 years, depending on their size and pathology.

Lifestyle Steps to Prevent Colon Cancer

Prevention doesn’t end with screening—healthy lifestyle choices can further reduce your risk:

  1. Adopt a High-Fiber Diet: Eat plenty of fruits, vegetables, whole grains, and legumes.
  2. Limit Red and Processed Meats: Reduce consumption of processed foods linked to higher cancer risk.
  3. Exercise Regularly: Aim for at least 150 minutes of moderate activity per week.
  4. Maintain a Healthy Weight: Obesity is a major risk factor, particularly for men.
  5. Avoid Smoking and Excess Alcohol: Both increase inflammation and cellular damage.
  6. Manage Chronic Conditions: Keep diabetes and IBD under control with regular medical care.

Why Early Detection Matters

Colon cancer is one of the few cancers that can be completely prevented through early detection. Studies show that removing polyps during colonoscopy reduces the risk of developing colon cancer by up to 90%.

When detected early, colon cancer is highly treatable—with a five-year survival rate exceeding 90%. Once it spreads to distant organs, however, survival drops sharply. This is why regular screening is one of the most important steps you can take for your long-term health.

 

Treatment Options

If colon cancer is diagnosed, treatment options depend on its stage and the patient’s overall health. These may include:

  • Surgery: Removal of the affected colon segment, often curative for early-stage cancers.
  • Chemotherapy: Targets residual cancer cells after surgery or reduces tumor size before surgery.
  • Radiation Therapy: Primarily used for rectal cancers.
  • Targeted and Immunotherapy: Modern treatments that focus on specific cancer pathways for advanced cases.

Early detection through colonoscopy can often prevent the need for extensive surgery or aggressive treatments.

Understanding Common Gastrointestinal Conditions: What Patients Should Know

Understanding Common Gastrointestinal Conditions: What Patients Should Know

by | Sep 25, 2025 | Cancer Screening, Gastroenterology, Gut Health, Liver Disease


Introduction

 

Digestive diseases range from common, easily managed problems to complex, life-altering disorders. Early recognition, accurate diagnosis and timely specialist care dramatically improve outcomes.

This article explains five major areas of gastrointestinal health — colorectal cancer and polyps; gastro-oesophageal reflux disease (GERD) and Barrett’s esophagus; Crohn’s disease and ulcerative colitis (the two main forms of inflammatory bowel disease, IBD); celiac disease; and fatty liver disease and gallstones — and highlights how patients in Cape Town can access expert assessment and treatment with Dr. Deetlefs.

 

Colorectal Polyps and Colorectal Cancer

 

Colorectal polyps are growths that form on the inner lining of the colon or rectum. While most polyps are benign, some — particularly adenomatous polyps — can slowly progress to colorectal cancer over several years. Colorectal cancer is one of the most common malignancies worldwide but is highly preventable and, when detected early, very treatable.

Symptoms And Red Flags:

  • Change in bowel habits (persistent diarrhea or constipation)
  • Rectal bleeding or blood in the stool
  • Unexplained iron-deficiency anemia
  • Abdominal pain or unexplained weight loss 

Diagnosis And Screening:
Colonoscopy remains the gold standard for detecting polyps and early cancer because it allows visualisation and removal (polypectomy) during the same procedure. Faecal immunochemical testing (FIT) and flexible sigmoidoscopy are other tools used in screening programs.

Treatment: Polypectomy at colonoscopy prevents progression to cancer. Early-stage colorectal cancers are managed with surgical removal and, when indicated, adjuvant therapies. Regular surveillance colonoscopies are recommended for patients with high-risk polyps.

Why Specialist Care Matters: A gastroenterologist such as Dr. Deetlefs can perform high-quality colonoscopy, assess polyp pathology, plan surveillance intervals, and co-ordinate multidisciplinary cancer care when necessary.

GERD and Barrett’s Esophagus

 

Gastro-esophageal reflux disease (GERD) occurs when stomach acid regularly flows back into the esophagus, causing heartburn and other symptoms.

Chronic acid exposure can damage the esophageal lining and lead to Barrett’s esophagus — a condition in which the normal squamous cells are replaced by columnar epithelium. Barrett’s is important because it increases the risk of esophageal adenocarcinoma.

Symptoms: Heartburn, regurgitation, difficulty swallowing (dysphagia), chest discomfort and chronic cough or hoarseness in some patients.

Diagnosis: Initial evaluation includes symptom assessment and trials of acid suppression. Endoscopy (esophago-gastro-duodenoscopy, OGD) with biopsies is necessary to diagnose Barrett’s and to look for dysplasia.

Management: Lifestyle measures (weight loss, head-of-bed elevation, dietary changes) and proton pump inhibitors (PPIs) are first-line treatments. Patients with Barrett’s are often enrolled in structured endoscopic surveillance; if dysplasia is found, endoscopic treatments such as radiofrequency ablation (RFA) or endoscopic mucosal resection (EMR) can remove abnormal tissue.

Role of a specialist: Dr. Deetlefs provides diagnostic endoscopy, surveillance for Barrett’s oesophagus and endoscopic therapies for dysplasia — interventions that can prevent progression to cancer.

Crohn’s Disease and Ulcerative Colitis (Inflammatory Bowel Disease)

 

Crohn’s disease and ulcerative colitis are chronic inflammatory disorders of the gastrointestinal tract. Crohn’s can affect any part of the GI tract from mouth to anus and is characterised by patchy inflammation; ulcerative colitis primarily affects the colon and rectum with continuous mucosal inflammation.

Symptoms: Persistent diarrhea (sometimes bloody), abdominal pain, urgency, weight loss, fatigue and extra-intestinal manifestations (joint pain, skin rashes, eye inflammation).

Diagnosis: A combination of history, blood tests, stool studies, endoscopy with biopsies and imaging (CT or MR enterography) is used to define disease extent and severity.

Treatment: Modern management aims for mucosal healing and long-term remission. Options include aminosalicylates, corticosteroids for flares, immunomodulators and biologic therapies (anti-TNF, anti-integrin and anti-IL agents). Nutritional support, smoking cessation (important in Crohn’s), and surgery for complications are also part of comprehensive care.

Specialist care importance: IBD is complex and benefits from a multidisciplinary team. Dr. Deetlefs offers diagnostic endoscopy, treatment planning including biologic therapy initiation and monitoring, and collaboration with surgeons, dietitians and radiologists to optimise outcomes.

Celiac Disease

 

Celiac disease is an autoimmune disorder triggered by dietary gluten in genetically predisposed individuals. It leads to small intestinal villous atrophy and malabsorption.

Symptoms: Diarrhea, steatorrhea, bloating, anemia, weight loss and sometimes non-gastrointestinal symptoms such as dermatitis herpetiformis or neuropathy. Some patients present with subtle signs or are asymptomatic.

Diagnosis: Serologic testing (tissue transglutaminase IgA, with total IgA assessment) followed by confirmatory duodenal biopsies via endoscopy when indicated.

Management: Lifelong strict gluten-free diet is the cornerstone. Dietitian input is essential for safe and nutritionally adequate dietary changes. Follow-up includes symptom review, serology, and, where necessary, repeat endoscopy.

How a gastroenterologist helps: Dr. Deetlefs diagnoses celiac disease using up-to-date testing protocols, arranges appropriate endoscopic biopsies, and refers patients to dietetic services to ensure safe dietary transition.

Fatty Liver Disease & Gallstones

 

Fatty liver disease: Non-alcoholic fatty liver disease (NAFLD) is increasingly common and linked to obesity, diabetes and metabolic syndrome. Most patients have simple steatosis, but a subset develop non-alcoholic steatohepatitis (NASH) with inflammation and fibrosis, which can progress to cirrhosis.

Gallstones: Gallstones form when bile components become imbalanced. Symptomatic gallstones cause biliary colic and can complicate with cholecystitis, choledocholithiasis (common bile duct stones) or pancreatitis.

Diagnosis and management: NAFLD is suspected on imaging (ultrasound) and abnormal liver blood tests; fibrosis assessment may require elastography or liver biopsy in selected cases. Management focuses on weight loss, control of metabolic risk factors and, where fibrosis is advanced, specialist hepatology input. Symptomatic gallstones are treated surgically with cholecystectomy; stones in the common bile duct often require endoscopic removal via ERCP (endoscopic retrograde cholangiopancreatography).

Link to gastroenterology services: Dr. Deetlefs partners with hepatology and surgical teams in Cape Town to investigate fatty liver, advise on metabolic risk reduction, and co-ordinate care for gallstone disease — including referral for ERCP when common bile duct stones are present.

How To Know When to See a Specialist

Seek specialist consultation if you have:

  • Persistent or unexplained gastrointestinal symptoms (bleeding, persistent pain, unintentional weight loss).
  • Abnormal screening tests (positive FIT, abnormal liver tests).
  • Chronic conditions requiring long-term management (IBD, celiac disease, Barrett’s oesophagus).
  • Complications (obstructive jaundice, recurrent pancreatitis, severe malnutrition).

Early referral allows definitive diagnosis, targeted treatment, and prevention of complications.
