Can coffee cause acid reflux?

Coffee may encourage reflux in susceptible people through its caffeine and other compounds, especially when taken in a large amount, on an empty stomach or close to lying down. Reflux can feel like burning behind the breastbone, a sour taste, throat irritation or a cough. A cup followed by symptoms does not prove that coffee is the sole cause. [Hiatus Hernia](/conditions/hiatus-hernia/), [Obesity](/conditions/obesity/) and meal size can also influence reflux.

Some people notice symptoms with caffeinated coffee but tolerate decaffeinated coffee; others react to both. Keep the distinction between a trigger and a diagnosis: recurrent symptoms may represent [Acid Reflux](/conditions/acid-reflux/) and deserve a clinical review.

Write down the coffee type, amount, additives, time and symptoms for several days. Try reducing the serving, avoiding coffee near bedtime and remaining upright after drinking it. Avoid changing many foods at once, because that makes patterns difficult to identify. If symptoms continue, a clinician can discuss lifestyle measures or [Acid Reflux Medication](/conditions/acid-reflux/) is not the treatment link; medication advice should be individualised. Persistent night symptoms may contribute to [Difficulty Sleeping](/symptoms/difficulty-sleeping/).

Book an appointment for frequent reflux, trouble swallowing, repeated vomiting, unexplained weight loss, persistent [Cough](/symptoms/cough/) or ongoing [Abdominal Pain](/symptoms/abdominal-pain/). Seek urgent help for severe chest pressure, breathlessness, fainting, sweating or pain spreading to the arm or jaw; [Chest Tightness](/symptoms/chest-tightness/) is not automatically reflux.

Ask whether your pattern fits reflux, whether a medication review is needed, and which warning symptoms should prompt urgent care. Mention night symptoms, cough and any known hernia.
