Understanding Gastroesophageal Reflux Disease

Heartburn, a burning sensation behind the breastbone, is the most recognizable symptom, along with regurgitation, the feeling of sour liquid or food rising into the throat or mouth. Symptoms are often worse after meals, when bending over, or when lying down at night.

GERD can also appear in less obvious ways, including a lingering cough, hoarseness, a sore throat in the morning, trouble swallowing, or the sensation of a lump in the throat.

When symptoms are typical, your gastroenterologist may begin with lifestyle changes and acid-reducing medicine, and a good response helps support the diagnosis. If symptoms persist, keep returning, or include warning signs, an upper endoscopy allows the doctor to look directly at the esophagus and check for irritation or other changes. Specialized tests that measure acid exposure or esophageal muscle function are available when the picture is less clear.

Daily habits make a real difference: eating smaller meals, finishing dinner a few hours before bedtime, raising the head of the bed, limiting personal trigger foods such as fried dishes, alcohol, and caffeine, reaching a healthy weight, and not smoking.

Acid-reducing medicines relieve symptoms for many people and come in several families and strengths. Long-standing or hard-to-control GERD deserves specialist follow-up, because years of acid exposure can change the lining of the esophagus — a condition called Barrett's esophagus that calls for periodic monitoring. For carefully selected patients, procedures that reinforce the reflux barrier are also an option.

Talk to a gastroenterologist if heartburn happens more than a couple of times a week, returns whenever medicine stops, or has gone on for years without a fresh look. Seek care promptly for trouble swallowing, food getting stuck, repeated vomiting, black stools, or unintended weight loss. Chest pain should always be evaluated urgently to rule out heart problems first.
