Can coffee cause heartburn?

Heartburn is a burning feeling behind the breastbone or in the upper chest, sometimes with a sour taste. Coffee may relax the barrier between the stomach and food pipe or irritate a sensitive stomach in some people. Large meals, lying down soon after eating and individual sensitivity can add to the problem. Repeated heartburn may occur with [Acid Reflux](/conditions/acid-reflux/), [Gastritis](/conditions/gastritis/) or a [Hiatus Hernia](/conditions/hiatus-hernia/).

A coffee trigger does not establish the cause. [Peptic Ulcer](/conditions/peptic-ulcer/) and other conditions can produce upper-abdominal discomfort, so persistent or changing symptoms merit a review.

Record the drink, additives, timing and symptoms. Consider a smaller serving, drinking it with food and leaving time before lying down. Test one adjustment at a time; some people tolerate decaffeinated coffee better, while others react to both forms. A clinician or pharmacist can advise whether [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) is suitable, especially if symptoms recur.

Arrange a medical appointment for frequent heartburn, difficulty swallowing, food sticking, repeated vomiting, black stools, persistent nausea or unexplained weight loss. Seek urgent help for severe chest pressure, breathlessness, fainting, sweating or pain spreading to the arm or jaw. Heartburn-like discomfort can overlap with heart problems.

Ask whether your symptoms fit reflux, whether testing is needed, how long self-care is reasonable, and which medicines or supplements could irritate your stomach.
