Gastroesophageal Reflux Disease (GERD): Causes, Symptoms, Diagnosis, Treatment and Diet

What Is GERD?

Gastroesophageal Reflux Disease, commonly known as GERD, is a chronic digestive disorder where stomach acid frequently flows back into the esophagus (the tube connecting the mouth and stomach). This backflow, known as acid reflux, irritates the lining of the esophagus and causes symptoms such as heartburn, chest discomfort, regurgitation, and a sour or bitter taste in the mouth.

While occasional acid reflux is normal and affects many people, GERD is diagnosed when acid reflux occurs more than twice a week or causes inflammation in the esophagus. It can significantly impact the quality of life if left untreated, leading to more serious health issues.

In India, increasing stress levels, sedentary lifestyles, unhealthy eating habits, and rising obesity are contributing to a growing number of GERD cases, affecting both adults and children.

What Causes GERD?

GERD occurs when the lower esophageal sphincter (LES) — a ring of muscle at the bottom of the esophagus — weakens or relaxes abnormally. This allows stomach acid to flow back into the esophagus.

Common causes and contributing factors include:

• Obesity: Excess body weight increases pressure on the stomach, pushing acid into the esophagus.
• Poor dietary habits: Frequent intake of spicy, oily, or acidic foods can aggravate reflux.
• Large meals or lying down after eating: This can delay digestion and promote reflux.
• Smoking and alcohol: These weaken the LES and increase stomach acid.
• Pregnancy: Hormonal changes and increased abdominal pressure contribute to reflux.
• Certain medications: Painkillers (NSAIDs), calcium channel blockers, sedatives, and antidepressants can relax the LES.
• Hiatal hernia: A condition where a part of the stomach pushes through the diaphragm, weakening the LES.

Understanding the root causes helps in tailoring treatment and lifestyle changes effectively.

Common Symptoms of GERD

GERD presents with a variety of symptoms that may range from mild to severe. Recognizing these symptoms early is key to timely diagnosis and management.

Most common symptoms include:

• Heartburn: A burning sensation in the chest, usually after meals or at night.
• Regurgitation: Sour or bitter-tasting acid backing up into the throat or mouth.
• Chest pain: Especially behind the breastbone, often mistaken for a heart attack.
• Difficulty swallowing (dysphagia): A feeling of food getting stuck in the throat.
• Sensation of a lump in the throat

Other associated symptoms:

• Chronic cough
• Hoarseness or sore throat
• Bad breath
• Nausea
• Bloating
• Asthma-like symptoms (wheezing, especially at night)

These symptoms may worsen when lying down or after heavy meals.

 

 

Who Is at Risk?

While GERD can affect people of all ages, certain groups are more susceptible due to lifestyle, genetics, or medical history.

Higher risk groups include:

• Overweight or obese individuals
• Pregnant women
• People with hiatal hernia
• Smokers and alcohol consumers
• Those with a sedentary lifestyle
• Individuals who frequently consume junk food, caffeine, or spicy meals
• Patients on long-term medications that affect LES tone
• People with diabetes or connective tissue disorders

It is important to monitor symptoms in these high-risk individuals for early intervention.

How GERD Affects the Body

When acid repeatedly escapes the stomach and irritates the esophageal lining, it can cause long-term complications. GERD doesn't just cause discomfort; it can damage the body in multiple ways.

Effects include:

• Esophagitis: Inflammation that can lead to ulcers and bleeding.
• Strictures: Scar tissue that narrows the esophagus and makes swallowing difficult.
• Barrett's esophagus: A precancerous condition where the esophagus lining changes due to long-term acid exposure.
• Dental erosion: Acid reflux can wear away enamel and cause cavities.
• Respiratory issues: Chronic reflux can worsen asthma or cause aspiration pneumonia.

Chronic, unmanaged GERD can severely impact a person’s nutrition, sleep quality, productivity, and overall well-being.

Complications If Left Untreated

Ignoring persistent GERD symptoms can result in serious health problems. Some complications include:

• Ulcers: Stomach acid can erode the esophagus, leading to painful ulcers.
• Bleeding: Long-term inflammation may cause small tears and bleeding.
• Esophageal stricture: Tightening or narrowing of the esophagus that interferes with swallowing.
• Barrett's Esophagus: Increases the risk of esophageal cancer.
• Sleep disturbances: Nighttime reflux can cause poor sleep, fatigue, and even mental health issues.
• Chronic cough and laryngitis: Especially when acid reaches the throat or lungs.

Prompt treatment can help prevent these long-term complications and improve the patient’s quality of life.

How is GERD Diagnosed?

Diagnosing GERD involves a combination of medical history, symptom evaluation, and diagnostic tests. Your doctor may begin by asking about your symptoms, how often they occur, and their severity. If GERD is suspected, one or more of the following diagnostic methods may be used:

1. Physical Examination and History

Initial assessment includes a discussion of your lifestyle, eating habits, and any medications you are taking.

A doctor may perform a physical exam to rule out other causes of your symptoms.

2. Trial Treatment

In many cases, doctors may suggest a trial of lifestyle changes or proton pump inhibitors (PPIs).

If symptoms improve significantly, GERD is often confirmed.

3. Endoscopy (Esophagogastroduodenoscopy or EGD)

A thin, flexible tube with a camera is inserted through the mouth to view the esophagus, stomach, and duodenum.

Can detect inflammation, ulcers, strictures, or Barrett’s esophagus.

4. Esophageal pH Monitoring

A probe is inserted into the esophagus for 24 hours to measure acid exposure.

It is the gold standard test for diagnosing GERD.

5. Esophageal Manometry

Measures the strength and coordination of esophageal muscles.

Helps evaluate if the lower esophageal sphincter is functioning properly.

6. Barium Swallow (Upper GI Series)

A patient swallows a contrast liquid (barium), and X-rays are taken to examine the esophagus and stomach.

Treatment Options for GERD

GERD treatment aims to reduce symptoms, heal the esophageal lining, and prevent complications. Depending on severity, your doctor may recommend one or more of the following approaches:

1. Lifestyle and Dietary Changes

• Avoid trigger foods (more on this below).
• Eat smaller, more frequent meals.
• Avoid lying down immediately after meals.
• Elevate the head of your bed by 6–8 inches.
• Lose weight if overweight.
• Quit smoking.

2. Medications

• Antacids: Provide quick, short-term relief by neutralizing stomach acid (e.g., Tums, Gelusil).
• H2 Receptor Blockers: Reduce acid production (e.g., ranitidine, famotidine).
• Proton Pump Inhibitors (PPIs): Stronger acid reducers that help heal the esophagus (e.g., omeprazole, pantoprazole, rabeprazole).
• Prokinetics: Help the stomach empty faster (e.g., domperidone, metoclopramide).

3. Surgery and Procedures

Considered in severe cases or when medications fail.

Common surgical options include:

• Nissen Fundoplication: The upper part of the stomach is wrapped around the lower esophagus to strengthen the LES.
• LINX Device: A ring of magnetic beads is placed around the LES to prevent reflux.

GERD Diet: What to Eat and What to Avoid

Food plays a major role in triggering or relieving GERD symptoms. Adopting a GERD-friendly diet can make a noticeable difference.

Foods to Avoid (Common Triggers)

• Spicy foods (chilli, pepper)
• Fried and fatty foods
• Citrus fruits (oranges, lemons)
• Tomato-based sauces and foods
• Chocolate
• Caffeine (tea, coffee)
• Carbonated drinks (soda, sparkling water)
• Onions and garlic
• Alcohol
• Mint and peppermint

Foods That May Help

• Oatmeal – Non-acidic and high in fiber.
• Bananas – Low-acid fruit.
• Ginger – Natural anti-inflammatory.
• Leafy greens – Non-acidic and nutrient-rich.
• Broccoli and cauliflower – High in fiber.
• Whole grains – Brown rice, couscous, quinoa.
• Lean proteins – Chicken, turkey, fish (grilled or baked).
• Low-fat dairy – Curd, yogurt.
• Herbal teas (except peppermint).

Sample GERD-Friendly Meal Plan (Indian Style)

Breakfast:

• Oats porridge with banana slices
• Herbal tea (ginger or blue tea)

Mid-morning Snack:

• Coconut water or buttermilk
• A handful of almonds

Lunch:

• Brown rice with mixed vegetable sabzi (low spice)
• Moong dal
• Curd (not sour)
• A piece of roti with ghee (no pickle)

Evening Snack:

• Roasted makhana or murmura
• Herbal tea

Dinner:

• Grilled chicken or paneer with sautéed vegetables
• Khichdi or plain paratha with bottle gourd curry
• Warm water post meal

Before Bed:

• A small cup of warm milk (if tolerated)

Additional Dietary Tips

• Eat slowly and chew food thoroughly.
• Don’t overeat.
• Stay upright for at least 2–3 hours after meals.
• Drink water between meals, not during.

Complications of Untreated GERD

While GERD may seem like a common and manageable condition, ignoring persistent symptoms can lead to more serious health issues over time. Some potential complications include:

1. Esophagitis

Chronic acid reflux can inflame and damage the lining of the esophagus, causing a condition called esophagitis. This may result in pain while swallowing and increase the risk of ulcers or bleeding.

2. Esophageal Strictures

Continuous inflammation can lead to the formation of scar tissue, narrowing the esophagus. This condition, called esophageal stricture, can cause difficulty swallowing (dysphagia) and the sensation of food being stuck.

3. Barrett’s Esophagus

In some people, prolonged exposure to stomach acid causes the cells lining the esophagus to change. This condition, known as Barrett’s Esophagus, increases the risk of developing esophageal cancer. Regular monitoring and biopsies are essential if diagnosed.

4. Esophageal Ulcers

Stomach acid can erode the esophageal lining, forming painful open sores. These ulcers can bleed and may require endoscopic treatment or medication for healing.

5. Respiratory Problems

Stomach acid entering the lungs or throat can cause chronic cough, asthma-like symptoms, hoarseness, or even aspiration pneumonia.

6. Dental Erosion

The acid can reach the mouth and erode tooth enamel, leading to sensitivity and dental decay.

Bottom Line: Early diagnosis and consistent management are key to avoiding long-term complications. Ignoring persistent GERD symptoms is never a good idea.

Prevention: How to Stop GERD from Worsening

The good news? GERD is largely preventable and manageable through a mix of lifestyle choices and dietary changes. Here are some preventive strategies:

1. Eat Smart

• Opt for low-fat, non-spicy meals.
• Avoid large, heavy dinners — eat your last meal at least 2–3 hours before bedtime.
• Don't skip meals or overeat.

2. Maintain a Healthy Weight

Excess abdominal fat puts pressure on the stomach, pushing acid up into the esophagus. Even a small reduction in weight can ease symptoms.

3. Quit Smoking

Smoking weakens the lower esophageal sphincter, allowing stomach contents to flow back upward.

4. Limit Alcohol and Caffeine

Both can irritate the esophagus and trigger acid reflux.

5. Wear Loose-Fitting Clothes

Tight clothes, especially around the waist, can increase pressure on your stomach and cause acid reflux.

6. Elevate the Head of Your Bed

Raising the bed by 6–8 inches can help prevent nighttime reflux. Use blocks or wedges — not pillows.

Lifestyle Tips to Manage GERD Naturally

Managing GERD doesn't always require medications or surgery. Many people find significant relief by adopting simple habits in daily life.

1. Chew Gum

Chewing sugar-free gum increases saliva production, which helps wash acid down into the stomach and reduces heartburn.

2. Stay Hydrated

Drinking water between meals can help dilute stomach acid and flush out irritants from the esophagus.

3. Mindful Eating

Eat slowly, chew food well, and avoid distractions like watching TV while eating.

4. Keep a Food Diary

Track what you eat and note when symptoms occur. Identifying personal trigger foods can help you make better dietary choices.

5. Practice Relaxation Techniques

Stress and anxiety can worsen GERD. Try yoga, meditation, or deep breathing exercises to keep your nervous system calm.

6. Stay Active — But Not Right After Meals

Physical activity helps regulate digestion. However, avoid lying down or exercising immediately after eating. Go for a gentle walk instead.

 

 

Frequently Asked Questions (FAQs)

Q1: Is GERD the same as acid reflux?

A: Acid reflux is a symptom (the backflow of stomach acid), while GERD is a chronic condition marked by frequent or severe acid reflux episodes.

Q2: Can GERD go away on its own?

A: Occasional acid reflux may resolve with minor changes, but GERD typically requires long-term lifestyle management and sometimes medical treatment.

Q3: Is it safe to take antacids daily?

A: Occasional use is fine, but long-term daily use may mask underlying issues and cause side effects like calcium imbalance or kidney problems. Always consult a doctor.

Q4: Can GERD cause cancer?

A: Chronic, unmanaged GERD can lead to Barrett’s Esophagus, which slightly raises the risk of esophageal cancer. Regular monitoring is essential.

Q5: Can children get GERD?

A: Yes. Infants, children, and teens can all experience GERD. Symptoms may include fussiness, vomiting, refusal to eat, or poor growth in infants.

Q6: What is “silent reflux”?

A: Silent reflux (Laryngopharyngeal Reflux or LPR) doesn't cause heartburn but can lead to symptoms like sore throat, hoarseness, cough, or the feeling of a lump in the throat.

Q7: How long does it take for GERD to heal?

A: With proper treatment and lifestyle changes, most people feel relief in a few weeks. Healing esophagitis or ulcers may take longer.

Q8: Are there any natural remedies for GERD?

A: Herbal teas (like ginger or chamomile), aloe vera juice (in moderation), and eating alkaline foods may help. But these are supportive measures — not substitutes for medical care.

Conclusion: Living Well with GERD

Gastroesophageal reflux disease may be a chronic condition, but it doesn't have to rule your life. With the right mix of timely diagnosis, dietary and lifestyle adjustments, stress management, and medical support when needed, you can control symptoms and protect your long-term health.
