Gastroesophageal Reflux Disease (GERD): Causes, Symptoms, and Treatment
Overview
Gastroesophageal reflux disease (GERD) is a common digestive condition that occurs when stomach acid and contents flow back into the esophagus. This backward flow causes irritation and a burning sensation in the chest, known as heartburn. Occasional reflux is normal, but frequent or severe symptoms may indicate GERD, which requires medical attention. Pregnant women are also more likely to experience acid reflux due to hormonal and physical changes.
Causes
Normally, a ring of muscle at the bottom of the esophagus (the lower esophageal sphincter) opens to allow food into the stomach and closes to prevent acid from coming back up. GERD occurs when this sphincter weakens or relaxes abnormally, allowing stomach acid to flow backward into the esophagus.
Risk Factors
-
Obesity
-
Smoking
-
Pregnancy
-
Hiatal hernia
-
Certain medications (e.g., sedatives, antihistamines, calcium channel blockers)
Common Symptoms
-
Burning sensation in the chest or throat (heartburn)
-
Chest pain or discomfort after eating
-
Difficulty or pain when swallowing
-
Sour or acidic taste in the mouth
-
Chronic cough or hoarseness
-
Bad breath
-
Gum inflammation or dental erosion
-
Frequent burping or increased saliva production
Triggering Factors
Certain foods and lifestyle habits can worsen GERD symptoms, such as:
-
Anxiety and stress
-
Large meals
-
Spicy foods
-
Citrus products
-
Tomato-based foods (e.g., ketchup, sauces)
-
Fried or fatty foods
-
Chocolate
-
Caffeinated drinks (coffee, soda)
-
Peppermint
When to See a Doctor
Consult a doctor if you experience:
-
Heartburn two or more times a week
-
Difficulty swallowing food or liquids
-
Persistent nausea or vomiting
-
Unexplained weight loss
-
Symptoms that don’t improve with medication
-
Signs of gastrointestinal bleeding (vomit with blood, black stool, or coffee-ground appearance)
Possible Complications
If untreated, GERD can lead to serious health issues, including:
-
Esophagitis (inflammation of the esophagus)
-
Peptic ulcers
-
Esophageal stricture (narrowing of the esophagus)
-
Barrett’s esophagus (a precancerous condition)
-
Chronic cough, laryngitis, and tooth enamel erosion
Diagnosis
Doctors typically diagnose GERD based on symptoms and medical history. If complications or other conditions are suspected, diagnostic tests may include:
-
Barium swallow X-ray
-
Upper endoscopy
-
Esophageal pH monitoring
Treatment Options
-
Antacids – Neutralize stomach acid for quick relief.
-
H2 receptor blockers – Reduce acid production.
-
Proton pump inhibitors (PPIs) – Block acid production and allow esophageal healing.
Prevention and Lifestyle Tips
Simple lifestyle changes can significantly reduce symptoms:
-
Avoid trigger foods and drinks.
-
Quit smoking.
-
Maintain a healthy weight.
-
Eat smaller, more frequent meals.
-
Avoid lying down immediately after eating (wait 2–3 hours).
-
Elevate the head of your bed by 6–8 inches (15–20 cm).
-
Wear loose-fitting clothing.
