What should you know about hernia and indigestion?

A hiatus hernia occurs when part of the stomach moves through the opening in the diaphragm where the food pipe passes. This can make acid reflux easier, causing burning behind the breastbone, a sour taste, belching, or discomfort after meals. A hernia may cause no symptoms, while indigestion can occur without a hernia.

Other explanations include gastritis, a peptic ulcer, gallstones, Helicobacter pylori infection, or medicines that irritate the stomach. Indigestion is a symptom, so its pattern, triggers, duration, and associated features help guide assessment rather than proving one diagnosis.

Notice whether symptoms follow large meals, lying down soon after eating, alcohol, smoking, or particular foods. Smaller meals, remaining upright after eating, and avoiding a personal trigger may reduce reflux symptoms. Ask a pharmacist or doctor before starting acid reflux medication, especially if you take other medicines or have ongoing symptoms.

Arrange a GP consultation when indigestion keeps returning, affects eating or sleep, or does not improve with sensible changes. The clinician may review medicines, examine you, and decide whether testing or further assessment is needed. Do not assume that a known hernia explains every new symptom.

Seek urgent care for vomiting blood, black stools, severe or sudden abdominal pain, repeated vomiting, trouble swallowing, fainting, or unexplained weight loss. Chest pressure or breathlessness with discomfort needs emergency assessment because heart problems can resemble indigestion.

Could my symptoms be acid reflux, a hiatus hernia, or another condition? Which changes or medication are suitable for me? Do I need testing because the symptoms are persistent or changing?
