Dark chocolate and acid reflux: what to know

Dark chocolate contains compounds that may reduce the tightness of the valve between the oesophagus and stomach. Its fat content can also slow stomach emptying for some people. This may allow stomach contents to move upward, causing burning behind the breastbone, a sour taste, regurgitation, cough, or disturbed sleep. A reaction after chocolate does not prove that every episode is reflux; other foods and conditions can cause similar discomfort.

Symptoms may be more noticeable after a large meal, when bending over, or when lying down soon after eating. Keeping a simple food and symptom diary can show whether chocolate is a repeat trigger.

Try avoiding dark chocolate for a short period, then discuss a cautious reintroduction with a clinician if symptoms settle. Keep portions modest, avoid eating close to bedtime, and remain upright after meals. Review other triggers such as mint, spicy meals, coffee, alcohol, or high-fat foods. A pharmacist or doctor can advise whether an acid-reducing medicine is suitable.

Get urgent help for chest pressure with sweating, breathlessness, faintness, or pain spreading to the arm or jaw. Arrange prompt assessment for trouble swallowing, vomiting blood, black stools, repeated vomiting, unexplained weight loss, or reflux that keeps returning despite practical changes.

Could my symptoms be reflux or another cause of chest or abdominal discomfort? Which foods and medicines should I review? Do I need treatment or testing if symptoms disturb sleep?
