Headache due to acidity

Acidity usually describes burning behind the breastbone, sour fluid rising into the throat, belching or upper-abdominal discomfort. Headache may appear at the same time because of missed meals, poor sleep, dehydration, stress or an illness, rather than because stomach acid directly causes it. A blocked nose or facial pressure can point toward allergic rhinitis or sinusitis. Fever, cough, body aches or exposure to infection may suggest a respiratory illness. Keeping the symptoms together in a timeline helps separate a shared trigger from two problems occurring at once.

Drink fluids, eat regular light meals and avoid lying down soon after eating. Notice whether spicy or fatty foods, caffeine, alcohol or late meals bring on burning. Raise the head of the bed if night reflux is frequent. Use an antacid or acid-reducing medicine only as directed by a pharmacist or clinician, particularly if you take other medicines or are pregnant. Record the headache location, duration and associated symptoms.

Get emergency help for a sudden severe headache, weakness on one side, confusion, fainting, trouble speaking, vomiting blood, black stools, severe chest pain or difficulty breathing. Arrange medical review for recurrent headaches, persistent reflux, trouble swallowing, unexplained weight loss, repeated vomiting or symptoms that do not settle.

Do my symptoms fit reflux, or should another headache cause be checked? Could any medicine be worsening the acidity? Which warning signs should make me seek urgent care?
