What should you know about chest pain caused by indigestion?

Indigestion, also called dyspepsia, often starts in the upper abdomen and can be felt higher in the chest. Discomfort may feel like burning, fullness, pressure, or an acidic taste rising into the throat. It can follow a large meal, eating quickly, lying down soon after eating, or foods that trigger reflux. Belching, bloating, nausea, and sour fluid in the mouth can occur alongside it.

Several digestive conditions can produce similar symptoms, including acid reflux, gastritis, a hiatus hernia, peptic ulcer disease, gallstones, or Helicobacter Pylori Infection. These possibilities are different from one another and may need different assessment. Read more about [Indigestion](/symptoms/indigestion/) and [Acid Reflux](/conditions/acid-reflux/).

If the discomfort is mild, familiar, and clearly linked with meals, sit upright and avoid lying flat for a while. Eat smaller portions, slow down while eating, and notice whether spicy, fatty, acidic, or caffeinated foods make symptoms worse. Avoid smoking and alcohol if they trigger symptoms. Keep a short record of timing, meals, body position, and associated symptoms; this can help a clinician identify a pattern.

Do not use someone else’s medicine or keep treating recurring chest discomfort without advice. A pharmacist or clinician can explain whether an appropriate antacid or acid-reducing treatment is suitable, and whether you need assessment for [Gastritis](/conditions/gastritis/) or [Peptic Ulcer](/conditions/peptic-ulcer/).

Call emergency services immediately for chest pain that is severe, crushing, tight, or persistent, or that spreads to the arm, back, neck, or jaw. Urgent help is also needed with breathlessness, fainting, cold sweating, marked weakness, confusion, or repeated vomiting. Do not drive yourself if you feel seriously unwell.

Arrange prompt medical advice for chest discomfort that keeps returning, is becoming more frequent, follows exertion, causes trouble swallowing, or comes with unexplained weight loss, black stools, vomiting blood, or ongoing abdominal pain. Digestive symptoms can overlap with heart and lung problems, so the sensation alone cannot safely identify the cause.

Ask what features make indigestion more likely in your case, whether your medicines or health conditions could contribute, and whether you need tests for reflux, an ulcer, gallstones, or Helicobacter pylori. You can also ask how long to try a treatment, what symptoms should prompt review, and whether [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/) is appropriate.
