Living with persistent acid reflux can be frustrating, especially when symptoms continue despite taking medication regularly. While occasional heartburn is common, ongoing reflux that does not improve may indicate an underlying digestive condition requiring further evaluation. If you continue to experience burning in your chest, regurgitation, difficulty swallowing, or chronic throat irritation, it may be time to consult an experienced Gastroenterology Clinic in Dubai.

At Dr. Rami Hamed Center (DRHC) Dubai, our gastroenterology specialists provide comprehensive evaluation and advanced diagnostic procedures, including gastroscopy, to determine the cause of persistent acid reflux and develop a personalized treatment plan.

What Is Acid Reflux?

Acid reflux occurs when stomach acid flows backward into the esophagus due to weakness or improper relaxation of the lower esophageal sphincter (LES). This backward flow irritates the lining of the esophagus, leading to uncomfortable symptoms.

If reflux occurs frequently, it may develop into Gastroesophageal Reflux Disease (GERD), a chronic condition that requires proper medical assessment and treatment.

Common Symptoms of Persistent Acid Reflux

• Burning sensation in the chest (heartburn)
• Acid or food coming back into the mouth
• Sour or bitter taste
• Chest discomfort after meals
• Difficulty swallowing
• Persistent cough or hoarseness
• Frequent throat clearing
• Feeling of a lump in the throat

Why Does Acid Reflux Continue Despite Medication?

Although medications such as proton pump inhibitors (PPIs) are effective for many patients, persistent symptoms may occur for several reasons.

1. The Condition May Not Be GERD

Several digestive disorders can mimic acid reflux, including:

• Oesophageal motility disorders
• Oesophageal spasm
• Gastroparesis
• Eosinophilic Gastrointestinal Disorders (EGIDs)
• Peptic ulcer disease

2. Severe GERD

Some patients have severe reflux due to significant weakness of the lower esophageal sphincter, allowing acid to frequently enter the esophagus.

3. Hiatal Hernia

A hiatal hernia can reduce the effectiveness of reflux medication and increase acid exposure to the esophagus.

4. Lifestyle Factors

Symptoms may persist because of:

• Eating large meals
• Late-night eating
• Obesity
• Smoking
• Alcohol consumption
• Spicy or fatty foods
• Excess caffeine

5. Incorrect Medication Use

Many acid-reducing medications work best when taken 30–60 minutes before meals. Taking them at the wrong time may reduce their effectiveness.

When Is Gastroscopy Needed?

A gastroscopy is one of the most valuable investigations for persistent acid reflux. It allows your gastroenterologist to examine the esophagus, stomach, and upper small intestine using a thin flexible camera.

Your specialist may recommend gastroscopy if:

• Symptoms continue despite medication.
• Heartburn has persisted for several months.
• Symptoms quickly return after stopping medication.
• You have difficulty swallowing.
• You experience unexplained weight loss.
• You have recurrent vomiting.
• You develop anemia.
• You notice vomiting blood or black stools.
• You are over 50 with new persistent reflux symptoms.

What Can Gastroscopy Detect?

Gastroscopy provides direct visualization of the upper digestive tract and helps diagnose conditions including:

• Esophagitis
• H. pylori infection (through biopsy)
• Gastric ulcers
• Duodenal ulcers
• Hiatal hernia
• Barrett's esophagus
• Esophageal narrowing (strictures)
• Polyps
• Early stomach and esophageal cancers

If necessary, your gastroenterologist may also recommend additional tests such as Wireless pH Monitoring or Oesophageal Manometry to further evaluate persistent symptoms.

Can Persistent Acid Reflux Lead to Complications?

Although many patients experience mild reflux, untreated GERD can lead to significant complications over time.

• Chronic inflammation of the esophagus
• Esophageal ulcers
• Bleeding
• Esophageal strictures
• Barrett's esophagus
• Increased risk of oesophageal cancer in selected patients

Early diagnosis helps reduce these risks and allows appropriate treatment before complications develop.

Treatment Options for Persistent GERD

Depending on the underlying cause, treatment may include:

• Lifestyle and dietary modifications
• Adjustment of acid-suppressing medications
• Treatment for H. pylori infection
• Stretta Treatment for selected GERD patients
• Endoscopic treatment when appropriate
• Long-term follow-up for patients with Barrett's esophagus

How Can You Help Control Acid Reflux?

Simple lifestyle changes often improve symptoms alongside medical treatment.

• Maintain a healthy weight.
• Avoid eating within three hours before bedtime.
• Eat smaller meals.
• Reduce spicy and fatty foods if they trigger symptoms.
• Limit caffeine and carbonated drinks.
• Stop smoking.
• Sleep with the head of your bed elevated.
• Take medications exactly as prescribed.

When Should You See a Gastroenterologist?

You should arrange an evaluation if:

• Your reflux occurs more than twice each week.
• Medication is no longer effective.
• You have difficulty swallowing.
• You experience unexplained weight loss.
• You have persistent nausea or vomiting.
• Your symptoms interfere with sleep or daily activities.
• You notice bleeding or black stools.

Early assessment can identify serious conditions before complications develop and help you regain long-term symptom control.
