Heartburn in the upper stomach: what to know

The upper stomach sits close to the lower chest and oesophagus, so reflux can be felt in either area. Burning after eating, sour regurgitation, belching, or worse symptoms when lying down support a reflux pattern. Pain that is localised, constant, or linked with vomiting may point to another problem, including [Gastritis](/conditions/gastritis/) or [Peptic Ulcer](/conditions/peptic-ulcer/).

Location alone cannot identify the cause. Tell a clinician whether the discomfort is burning, cramping, sharp, or pressure-like, and whether food changes it.

Use smaller portions, eat slowly, and stay upright after meals. Avoid foods or drinks that consistently bring on burning, and avoid tight waistbands. Keep a brief record of meal timing, posture, and associated symptoms. If you are considering [Acid Reflux Medication](/treatments/medical-management/acid-reflux-medication/), ask a pharmacist or doctor to check it against your health conditions and current medicines.

Get urgent help for chest pressure, breathlessness, sweating, faintness, or pain spreading to the arm or jaw. Seek prompt care for severe or worsening upper-abdominal pain, repeated vomiting, vomiting blood, black stools, fever, yellowing of the skin, or difficulty swallowing. Arrange a routine assessment if symptoms persist, recur often, or affect eating and sleep.

Ask whether the pattern is more consistent with reflux, [Hiatus Hernia](/conditions/hiatus-hernia/), or another digestive cause, and whether you need an examination or treatment trial. Mention pain after meals, night symptoms, and every medicine or supplement you use.
