Heartburn is one of the most common digestive complaints worldwide, affecting millions of people every day. While occasional heartburn after a rich meal is usually harmless, frequent or persistent symptoms may indicate an underlying digestive condition that requires medical attention. Heartburn, acid reflux, and GERD are closely related conditions that can significantly affect quality of life when left untreated.

Many people attempt to manage heartburn with lifestyle changes such as avoiding spicy foods, reducing alcohol intake, or taking over-the-counter medications. While these measures often provide temporary relief, they may not be enough for individuals experiencing chronic symptoms. Persistent heartburn can be a sign of a more serious digestive disorder and should never be ignored.

At Dr. Eduan Deetlefs’ practice, patients receive comprehensive evaluation and personalized treatment plans to address the underlying causes of heartburn and reflux.

Understanding why heartburn occurs and knowing when to seek professional care can help prevent complications and improve long-term digestive health.

 

What Is Heartburn?

Heartburn is a burning sensation felt behind the breastbone that occurs when stomach acid flows backward into the esophagus. Unlike the stomach, the esophagus lacks a protective lining capable of withstanding acidic digestive contents. As a result, repeated exposure to stomach acid causes irritation and inflammation.

Heartburn symptoms may include:

• Burning pain in the chest
• A sour or acidic taste in the mouth
• Regurgitation of food or liquid
• Difficulty swallowing
• Chronic cough
• Hoarseness or throat irritation

Occasional heartburn is common and usually occurs after eating large meals or consuming trigger foods. However, when symptoms occur more than twice a week, it may indicate Gastroesophageal Reflux Disease (GERD).

For patients experiencing ongoing symptoms, a consultation and evaluation through a gastroscopy may help identify underlying causes and guide treatment.

Why Does Heartburn Happen?

At the junction between the esophagus and stomach is a muscular valve called the lower esophageal sphincter (LES). This valve normally opens to allow food into the stomach and closes to prevent acid from flowing backward.

Heartburn develops when the LES weakens or relaxes inappropriately, allowing stomach contents to reflux into the esophagus.

Several factors can contribute to this process, including dietary habits, lifestyle choices, structural abnormalities, and certain medical conditions.

 

Common Causes of Persistent Heartburn

1. Gastroesophageal Reflux Disease (GERD)

GERD is the most common cause of chronic heartburn. In patients with GERD, acid reflux occurs regularly due to dysfunction of the lower esophageal sphincter.

Common GERD triggers include:

• Fatty and fried foods
• Spicy foods
• Chocolate
• Coffee and caffeinated beverages
• Carbonated drinks
• Alcohol
• Large meals

Without proper treatment, GERD can lead to long-term damage of the esophageal lining.

2. Hiatal Hernia 

A hiatal hernia occurs when a portion of the stomach pushes upward through the diaphragm into the chest cavity. This structural change can interfere with the normal function of the LES and significantly increase acid reflux.

Many patients with chronic heartburn are found to have a hiatal hernia during endoscopic evaluation.

3. Obesity

Excess body weight places increased pressure on the abdomen, which can force stomach acid upward into the esophagus. Studies consistently show that overweight and obese individuals have a higher risk of developing GERD and chronic heartburn.

Even modest weight loss can significantly improve symptoms.

4. Certain Medications 

Some medications may contribute to reflux by relaxing the LES or irritating the esophagus.

Examples include:

• Anti-inflammatory medications (NSAIDs)
• Certain blood pressure medications
• Sedatives
• Some asthma medications

Patients experiencing persistent heartburn should discuss all medications with their healthcare provider.

5. Lifestyle Factors

Several everyday habits can worsen reflux symptoms:

• Smoking
• Excessive alcohol consumption
• Eating large meals late at night
• Lying down shortly after eating
• Wearing tight-fitting clothing around the abdomen

While modifying these habits can help, lifestyle changes alone are not always sufficient for chronic cases.

 

When Lifestyle Changes Aren’t Enough

 

Many patients spend months or even years trying to control heartburn through dietary changes and self-medication. Unfortunately, persistent symptoms often indicate a more complex problem.

You should consider seeking medical evaluation if:

• Heartburn occurs more than twice per week
• Symptoms persist despite over-the-counter medications
• Reflux symptoms interfere with sleep
• You develop difficulty swallowing
• You experience unexplained weight loss
• Symptoms worsen over time
• You experience frequent regurgitation

Persistent symptoms can indicate GERD, esophagitis, Barrett’s esophagus, or other digestive conditions that require specialist care.

 

Lifestyle Measures That Still Matter

 

Although lifestyle changes may not completely eliminate heartburn, they remain an important part of treatment.

Dietary Adjustments

Patients are often advised to:

• Avoid trigger foods
• Eat smaller meals
• Avoid overeating
• Reduce acidic foods and beverages

Keeping a food diary can help identify individual triggers.

 

Meal Timing

Avoid lying down for at least two to three hours after eating. Late-night meals are a common cause of nighttime reflux symptoms.

 

Weight Management

Losing excess weight reduces abdominal pressure and often leads to substantial symptom improvement.

 

Smoking and Alcohol Cessation

Both smoking and alcohol can weaken the LES and increase acid reflux. Reducing or eliminating these habits can enhance treatment effectiveness.

 

Medical Treatments for Persistent Heartburn

Over-the-Counter Medications

Several non-prescription treatments are available:

Antacids

Antacids neutralize stomach acid and provide rapid but short-term relief.

H2 Receptor Blockers

These medications reduce acid production and can provide longer-lasting symptom control.

Proton Pump Inhibitors (PPIs)

PPIs are among the most effective medications for GERD and persistent heartburn. They significantly reduce acid production and allow the esophagus to heal.

However, prolonged use should be monitored by a healthcare professional.

 

Prescription Treatments

 

When symptoms persist despite OTC medications, stronger prescription therapies may be required.

A gastroenterologist may prescribe:

• Higher-dose PPIs
• Medications that improve stomach emptying
• Therapies aimed at strengthening LES function

Treatment plans are individualized based on the patient’s symptoms, medical history, and diagnostic findings.

 

Advanced Endoscopic Treatments

 

For patients with severe reflux or complications, advanced endoscopic interventions may be recommended.

Endoscopic Dilatation

Chronic acid exposure can cause scar tissue formation and narrowing of the esophagus, known as a stricture.

Endoscopic dilatation gently stretches these narrowed areas, improving swallowing and reducing discomfort.

Endoscopic Fundoplication

This minimally invasive procedure helps reinforce the lower esophageal sphincter and reduce reflux without traditional surgery.

Many patients experience significant symptom improvement following treatment.

Surgical Options

 

When medications and endoscopic treatments fail to adequately control symptoms, surgery may be considered.

Nissen Fundoplication

Nissen fundoplication remains the gold-standard surgical treatment for severe GERD.

During the procedure:

• The upper portion of the stomach is wrapped around the lower esophagus.
• The LES is strengthened.
• Acid reflux is significantly reduced.

Surgery is typically reserved for carefully selected patients after comprehensive evaluation.

 

Potential Complications of Untreated Heartburn

 

Ignoring persistent heartburn can have serious consequences.

Esophagitis

Repeated acid exposure causes inflammation of the esophageal lining, leading to pain and difficulty swallowing. 

Esophageal Ulcers

Chronic irritation may cause open sores within the esophagus, resulting in pain and bleeding.

Esophageal Strictures

Scar tissue can narrow the esophagus, making swallowing increasingly difficult. 

Barrett’s Esophagus

Barrett’s esophagus occurs when long-term acid exposure changes the lining of the esophagus.
Patients diagnosed with Barrett’s esophagus require regular monitoring because the condition increases the risk of esophageal cancer.

Increased Cancer Risk

Although uncommon, untreated GERD and Barrett’s esophagus increase the risk of developing esophageal adenocarcinoma.

Early diagnosis dramatically improves outcomes.

 

How a Gastroenterologist Can Help

 

A gastroenterologist specializes in diagnosing and treating digestive disorders, including persistent heartburn and GERD.

Dr. Deetlefs may recommend several diagnostic investigations, including:

Upper Endoscopy (Gastroscopy)

A gastroscopy allows direct visualization of the esophagus, stomach, and upper digestive tract.

This procedure can identify:

• Inflammation
• Ulcers
• Strictures
• Barrett’s esophagus
• Hiatal hernias

pH Monitoring

This test measures acid exposure within the esophagus and helps confirm GERD.

 

Esophageal Manometry

Manometry evaluates the function and coordination of esophageal muscles and the LES.

These investigations help create an accurate diagnosis and guide personalized treatment recommendations.

 

Practical Tips for Managing Heartburn Daily

 

While receiving treatment, these strategies may help reduce symptoms:

1. Keep a food diary.
2. Eat slowly and chew thoroughly.
3. Avoid overeating.
4. Stay upright after meals.
5. Wear loose-fitting clothing.
6. Elevate the head of your bed by 15–20 cm.
7. Limit alcohol and caffeine.
8. Maintain a healthy body weight.

Small daily habits can have a meaningful impact on symptom control.

 

When to Seek Immediate Medical Attention

 

Seek urgent medical evaluation if you experience:

• Severe chest pain
• Difficulty swallowing
• Vomiting blood
• Black or tarry stools
• Sudden unexplained weight loss
• Persistent vomiting

These symptoms may indicate serious complications that require prompt treatment.

Acid reflux, gastroesophageal reflux disease (GERD), and chronic heartburn are among the most common digestive conditions affecting adults worldwide. While occasional reflux after a heavy meal is normal, persistent acid reflux can significantly impact quality of life and may lead to serious complications if left untreated. Symptoms such as burning chest discomfort, regurgitation, chronic cough, hoarseness, difficulty swallowing, and disturbed sleep can become increasingly difficult to manage over time.

For many patients, lifestyle changes and medication provide relief. However, some individuals continue to experience symptoms despite treatment, while others develop complications that require more advanced intervention. Fortunately, modern gastroenterology now offers a range of minimally invasive endoscopic treatments that can help manage acid reflux effectively without the need for major surgery.

At GI Doc Cape Town, Dr Eduan Deetlefs offers comprehensive evaluation and advanced endoscopic treatment options for patients suffering from GERD and its complications.

Through diagnostic gastroscopy, therapeutic endoscopy, treatment of Barrett’s oesophagus, dilatation of strictures, and specialised reflux management, patients can receive personalised care designed to improve long-term digestive health.

 

Understanding Acid Reflux and GERD

 

Acid reflux occurs when stomach acid flows backward into the oesophagus. Normally, a muscular valve called the lower oesophageal sphincter (LES) prevents stomach contents from moving upward. When this valve weakens or relaxes abnormally, acid can travel back into the oesophagus, causing irritation and inflammation.

Occasional reflux is common and may occur after large meals, spicy foods, alcohol consumption, or lying down shortly after eating.

However, when reflux becomes frequent or severe, it is classified as gastroesophageal reflux disease (GERD).

 

Common symptoms of GERD include:

• Burning chest pain or heartburn
• Sour taste in the mouth
• Regurgitation of food or acid
• Chronic throat irritation
• Persistent cough
• Hoarseness
• Difficulty swallowing
• Chest discomfort
• Bloating and nausea

Some patients experience “silent reflux,” where throat symptoms occur without obvious heartburn. Others may mistake reflux symptoms for cardiac problems due to chest pain or discomfort.

Without proper treatment, chronic reflux can damage the lining of the oesophagus and increase the risk of complications.

 

Why Chronic Acid Reflux Should Not Be Ignored

 

Many people self-manage reflux symptoms with over-the-counter medications for years without investigating the underlying cause. While antacids and acid-suppressing medications can provide relief, persistent reflux may indicate more serious disease.

Untreated GERD can lead to:

• Oesophagitis (inflammation of the oesophagus)
• Oesophageal ulcers
• Bleeding
• Narrowing of the oesophagus (strictures)
• Difficulty swallowing
• Barrett’s oesophagus
• Increased risk of oesophageal cancer

Because symptoms alone do not always reflect the severity of disease, specialist evaluation is important when reflux becomes chronic, severe, or resistant to treatment.

At GI Doc Cape Town, Dr Deetlefs provides advanced diagnostic investigations to assess reflux severity, identify complications, and determine the most effective treatment strategy for each patient.

 

The Role of Gastroscopy in Acid Reflux Management

 

Gastroscopy, also known as upper endoscopy, is one of the most important tools in evaluating acid reflux and GERD.

During the procedure, a thin flexible camera is passed through the mouth into the oesophagus, stomach, and upper small intestine. This allows direct visualisation of inflammation, ulcers, narrowing, abnormal tissue changes, and other complications associated with reflux disease.

Gastroscopy may be recommended for patients with:

• Persistent reflux symptoms
• Difficulty swallowing
• Chronic cough or throat irritation
• Unexplained chest pain
• Suspected Barrett’s oesophagus
• Bleeding or anaemia
• Symptoms not responding to medication

The procedure also allows biopsies to be taken if abnormal tissue is detected. These samples can help diagnose Barrett’s oesophagus, infections, inflammation, or precancerous changes.

Dr Deetlefs performs diagnostic and therapeutic gastroscopy using advanced endoscopic technology, helping patients receive accurate diagnoses and early intervention before complications worsen.

 

Barrett’s Oesophagus: A Serious Reflux Complication

 

One of the most important complications of chronic acid reflux is Barrett’s oesophagus. This condition develops when repeated exposure to stomach acid causes changes in the cells lining the lower oesophagus.

Although Barrett’s oesophagus itself may not cause additional symptoms, it is considered a precancerous condition because it increases the risk of oesophageal adenocarcinoma.

Risk factors for Barrett’s oesophagus include:

• Long-standing GERD
• Chronic heartburn
• Obesity
• Smoking
• Hiatal hernia
• Male gender
• Age over 50

Because Barrett’s oesophagus can develop silently, many patients are unaware they have it until an endoscopy is performed.

Early diagnosis is essential because endoscopic treatments can remove or destroy abnormal tissue before cancer develops.

Endoscopic Treatment for Barrett’s Oesophagus

 

Modern therapeutic endoscopy has transformed the management of Barrett’s oesophagus. Instead of requiring major surgery, many patients can now undergo minimally invasive endoscopic procedures that target abnormal tissue directly.

Dr Deetlefs offers advanced Barrett’s oesophagus management including:

• Surveillance endoscopy
• Endoscopic mucosal resection (EMR)
• Ablation therapy
• Biopsy monitoring
• Long-term reflux management

Endoscopic Mucosal Resection (EMR)

 

EMR involves removing abnormal or precancerous tissue from the oesophageal lining using specialised endoscopic instruments. This procedure allows targeted treatment while preserving healthy surrounding tissue.

EMR is commonly used when abnormal cells or early cancerous changes are detected during surveillance endoscopy.

 

Ablation Therapy

 

Ablation techniques destroy abnormal Barrett’s tissue using controlled energy delivery. This allows healthy tissue to regrow while reducing cancer risk.

Endoscopic ablation is minimally invasive and can often be performed without hospital admission.

These advanced therapies allow earlier intervention and may prevent progression to oesophageal cancer.

Managing Oesophageal Strictures with Endoscopic Dilatation

 

Chronic acid exposure can sometimes cause scar tissue formation within the oesophagus. Over time, this may narrow the oesophageal passage, leading to a condition called oesophageal stricture.

Patients with strictures often experience:

• Difficulty swallowing
• Food getting stuck
• Pain when swallowing
• Weight loss
• Regurgitation

Endoscopic dilatation is an effective minimally invasive treatment for oesophageal strictures.

During the procedure, specialised instruments gently stretch the narrowed section of the oesophagus, improving swallowing and relieving obstruction.

Dr Deetlefs performs oesophageal dilatation procedures for patients with reflux-related strictures and other causes of oesophageal narrowing. In severe cases, stent placement may also be considered to maintain oesophageal patency.

The Connection Between Hiatal Hernias and Reflux

 

A hiatal hernia occurs when part of the stomach pushes upward through the diaphragm into the chest cavity. This can weaken the lower oesophageal sphincter and worsen acid reflux symptoms.

Many patients with chronic GERD also have hiatal hernias.

Gastroscopy can help identify hiatal hernias and assess the degree of reflux-related damage within the oesophagus.

Understanding whether a hiatal hernia contributes to reflux symptoms helps guide long-term treatment decisions.

 

Lifestyle Changes Still Matter

 

While advanced endoscopic treatments can be highly effective, lifestyle modification remains an important part of reflux management.

Patients are often advised to:

• Avoid large late-night meals
• Reduce alcohol intake
• Limit spicy or acidic foods
• Stop smoking
• Maintain a healthy weight
• Elevate the head of the bed
• Avoid lying down after meals

These measures may reduce symptom severity and improve the effectiveness of medical or endoscopic treatment.

Dr Deetlefs works closely with patients to develop personalised management plans that combine lifestyle modification, medication when necessary, and advanced procedural intervention when indicated.

 

When Should You See a Gastroenterologist?

 

Many people ignore reflux symptoms for years, assuming heartburn is simply a normal inconvenience. However, persistent symptoms should always be evaluated by a specialist, particularly if they interfere with daily life or worsen over time.

You should consider seeing a gastroenterologist if you experience:

• Frequent heartburn
• Symptoms lasting longer than several weeks
• Difficulty swallowing
• Unexplained weight loss
• Chronic cough or hoarseness
• Chest discomfort
• Regurgitation
• Poor response to medication
• Bleeding or black stools

Early investigation can identify complications before they become severe and may significantly improve long-term outcomes.
