Gastroesophageal Reflux Disease (GERD): Causes, Symptoms & Treatment

Overview

Gastroesophageal Reflux Disease (GERD) is a chronic digestive disorder where stomach acid or bile flows back into the esophagus, causing irritation and inflammation. This backflow (reflux) occurs when the lower esophageal sphincter (LES) weakens or relaxes inappropriately. GERD is a common condition in India, affecting millions, often linked to dietary habits, lifestyle, and stress. If left untreated, it can lead to complications like esophagitis, Barrett's esophagus, or even esophageal cancer.

Causes

GERD occurs due to a combination of factors that weaken the LES or increase abdominal pressure. Common causes include:

• Hiatal hernia: A condition where part of the stomach pushes through the diaphragm.
• Delayed stomach emptying (gastroparesis).
• Obesity or excess weight, which increases abdominal pressure.
• Pregnancy due to hormonal changes and pressure on the stomach.
• Certain medications like NSAIDs, calcium channel blockers, or sedatives.
• Smoking and alcohol consumption.
• Dietary triggers: spicy, fried, or fatty foods, citrus fruits, chocolate, caffeine, and carbonated drinks.
• Large meals or eating close to bedtime.

Symptoms

Common symptoms of GERD include:

• Heartburn: a burning sensation in the chest, often after eating or at night.
• Regurgitation: sour or bitter-tasting acid backing up into the throat or mouth.
• Dysphagia: difficulty swallowing or feeling of a lump in the throat.
• Chest pain, sometimes mistaken for a heart attack.
• Chronic cough, hoarseness, or sore throat.
• Asthma-like symptoms or wheezing.
• Nausea or vomiting, especially after meals.
• Excessive burping or bloating.

Diagnosis

Diagnosis of GERD is based on symptoms and may include:

• Clinical history and physical examination.
• Upper endoscopy (EGD) to visualize esophageal damage.
• Ambulatory pH monitoring to measure acid levels in the esophagus.
• Esophageal manometry to assess LES function.
• Barium swallow X-ray to detect hiatal hernia or strictures.
• Trial of proton pump inhibitors (PPIs) to confirm diagnosis.

Treatment Options

Lifestyle Modifications

• Eat smaller, more frequent meals.
• Avoid trigger foods (spicy, fatty, acidic).
• Do not lie down for 2-3 hours after eating.
• Elevate the head of the bed by 6-8 inches.
• Lose weight if overweight.
• Quit smoking and limit alcohol.

Medications

• Antacids for quick relief.
• H2 receptor blockers (e.g., famotidine) to reduce acid production.
• Proton pump inhibitors (e.g., omeprazole, pantoprazole) for severe cases.
• Prokinetics to improve stomach emptying.

Surgery

• Fundoplication (wrapping the top of the stomach around the LES) for refractory cases.
• LINX device implantation to strengthen the LES.

Prevention

• Maintain a healthy weight.
• Avoid large meals and late-night eating.
• Identify and avoid personal trigger foods.
• Wear loose-fitting clothes to reduce abdominal pressure.
• Manage stress through yoga, meditation, or breathing exercises.
• Avoid bending or heavy lifting after meals.

Ayurvedic Perspective & Remedies

In Ayurveda, GERD is correlated with Amlapitta (hyperacidity) caused by aggravated Pitta dosha. Ayurvedic management focuses on balancing Pitta through diet, herbs, and lifestyle.

• Diet: Consume cooling foods like cucumber, coconut water, milk, and ghee. Avoid spicy, sour, and fried foods.
• Herbs: Licorice root (Yashtimadhu), Amla (Indian gooseberry), and Shankhpushpi help soothe the stomach lining.
• Home remedies: Drink a glass of buttermilk with roasted cumin powder after meals. Chew fennel seeds or cardamom.
• Panchakarma: Virechana (therapeutic purgation) may be recommended under expert guidance to eliminate excess Pitta.
• Lifestyle: Practice Pranayama (cooling breath) and avoid daytime sleep.

Always consult a qualified Ayurvedic practitioner before starting any remedy.
