What should you know about fasting and acid reflux?

Fasting can worsen acid reflux for some people because an empty stomach, dehydration, or a large meal afterward may aggravate symptoms. Keep meals moderate when eating, avoid lying down soon afterward, and discuss medication timing with a clinician rather than changing it yourself.

Acid reflux happens when stomach contents move upwards into the oesophagus. Long gaps between meals may be followed by rapid eating or a heavy meal, which can increase pressure in the stomach. Some people notice burning, regurgitation, cough, chest tightness, or difficulty sleeping. A hiatus hernia and obesity can increase reflux symptoms, but symptoms can occur without either condition.

If you choose to fast, plan a balanced meal before the fast and eat slowly when it ends. Limit foods and drinks that you know trigger symptoms, and remain upright after eating. Sip fluids during permitted times and avoid smoking. Raise the head of the bed if night symptoms occur. Ask a clinician or pharmacist how to schedule acid-reflux treatment around fasting; do not crush, double, or skip a medicine without advice.

Get urgent help for chest tightness with breathlessness, sweating, faintness, or pain spreading to the arm or jaw, because heart problems can resemble reflux. Seek prompt care for vomiting blood, black stools, repeated vomiting, food sticking, or severe abdominal pain. Arrange a review when symptoms are frequent, disturb sleep, or do not settle with your usual plan.

Ask whether your symptoms fit acid reflux, whether a hiatus hernia or another condition needs checking, and how to time treatment during fasting. Mention cough, sleep disruption, swallowing difficulty, and any chest symptoms.
