GERD is a chronic digestive disorder that occurs when stomach acid or bile frequently flows back up into the esophagus — the tube connecting your mouth to your stomach. This backwash (reflux) can irritate the lining of your esophagus.
Symptoms:
-Heartburn: A burning sensation in your chest that often occurs after eating and worsens when lying down.
-Regurgitation: The backward flow of stomach contents into the mouth.
-Chest pain: May mimic heart attack pain.
-Difficulty swallowing
-Chronic cough
-Hoarseness
-Sore throat
-Asthma
Causes:
-Weakening of the lower esophageal sphincter (LES): The LES is a ring of muscle that normally prevents stomach acid from flowing back up into the esophagus. If it weakens or relaxes inappropriately, acid can reflux.
-Hiatal hernia: A condition where part of the stomach pushes up through the diaphragm (the muscle separating the chest and abdomen).
-Certain foods and drinks:
Fatty foods
Spicy foods
Citrus fruits
Tomato-based products
Alcohol
Caffeine
Chocolate
Peppermint
Onions
Garlic
Medications:
Some medications, such as aspirin, ibuprofen, and some blood pressure medications, can relax the LES.
Pregnancy: Hormonal changes during pregnancy can relax the LES.
Obesity: Excess weight can increase pressure on the abdomen, forcing stomach acid back up into the esophagus.
Diagnosis:
Medical history and physical exam
Upper endoscopy: A procedure to examine the esophagus with a thin, flexible tube with a light and camera.
Esophageal manometry: Measures the pressure within the esophagus and LES.
24-hour pH monitoring: Monitors the acidity of the esophagus over a 24-hour period.
Treatment:
Lifestyle changes:
Dietary changes: Avoid trigger foods and eat smaller, more frequent meals.
Weight loss: If overweight or obese.
Elevate the head of the bed:
Quit smoking:
Avoid lying down after eating
Medications:
Antacids: Neutralize stomach acid.
H2 blockers: Reduce stomach acid production.
Proton pump inhibitors (PPIs): Strongly reduce stomach acid production.
Surgery: In severe cases, surgery may be an option.
