GERD (Acid Reflux) — Symptoms, Causes & Treatment

What gastroesophageal reflux disease is, its symptoms, common triggers, and how it's diagnosed and treated.

What Is GERD?

Gastroesophageal reflux disease (GERD) happens when stomach acid frequently flows back into the oesophagus, irritating its lining. Occasional reflux is normal — GERD is when it happens often enough to cause symptoms or damage.

Common Symptoms

See a doctor promptly if: You have difficulty swallowing, unintentional weight loss, vomiting blood, or black/tarry stools.

Common Triggers

Tests Your Doctor May Order

TestPurpose
Upper endoscopyExamines the oesophagus and stomach lining for damage
pH monitoringMeasures acid exposure in the oesophagus over 24 hours
Barium swallow X-rayShows structural abnormalities or reflux
Oesophageal manometryChecks muscle function of the oesophagus

Treatment

Lifestyle: weight loss, smaller meals, avoiding trigger foods, raising the head of the bed, not lying down within 3 hours of eating.

Medications: antacids, H2 blockers (famotidine), proton pump inhibitors (omeprazole) — often used short or long-term depending on severity.

Important: Persistent or severe GERD symptoms should be evaluated by a doctor, as long-term acid exposure can damage the oesophagus.
