What should you know about caffeine and acid reflux?

Acid reflux occurs when stomach contents move up into the oesophagus. Caffeinated coffee, tea, cola, energy drinks, and some medicines may aggravate burning, sour taste, regurgitation, cough, or sleep disruption in certain people. The drink’s volume, acidity, sugar, fat, and timing may also contribute, so caffeine may not be the only factor. Hiatus hernia, excess weight, and other conditions can influence symptoms.

Keep a short diary of drinks, meals, timing, and symptoms. If caffeine appears to trigger symptoms, reduce it gradually or choose a lower-caffeine option, then observe whether the pattern changes. Avoid lying down soon after eating, and use any prescribed reflux treatment as directed. Do not stop an essential medicine without checking its caffeine content and asking a clinician about alternatives. Personal triggers are more useful than a blanket rule.

Arrange a medical review for frequent reflux, symptoms that persist despite treatment, unexplained weight loss, repeated vomiting, food sticking, or black stools. Seek urgent help for severe chest pressure, breathlessness, sweating, faintness, or pain spreading to the arm or jaw, because heart problems can resemble reflux. A persistent cough also deserves assessment rather than automatic attribution to caffeine.

Ask whether your symptoms fit acid reflux, whether another cause should be checked, which caffeine substitutes are suitable, and how long to try lifestyle changes before reviewing treatment.
