Indigestion and loss of appetite: what to know

Stomach irritation such as Gastritis or a Peptic Ulcer can reduce appetite while causing pain or nausea. Gastroenteritis, Influenza, COVID-19, or Hepatitis A may also make food less appealing when illness affects the whole body. Depression can alter appetite and digestion too. A symptom does not identify one condition by itself; a clinician may ask about medicines, alcohol, bowel changes, weight change, and the pattern of discomfort.

Try small, frequent meals and choose foods that feel easy to tolerate. Sip fluids regularly, eat slowly, and avoid lying down soon after eating. Notice whether fatty, spicy, acidic, or alcoholic drinks worsen symptoms. Keep a brief record of meals, discomfort, appetite, vomiting, bowel changes, and medicines. Do not stop prescribed treatment without advice. If appetite remains low, arrange a review so hydration, nutrition, and the underlying cause can be considered.

Seek urgent medical help for severe or worsening abdominal pain, repeated vomiting, vomit containing blood, black stools, faintness, confusion, or inability to keep fluids down. Arrange prompt assessment for ongoing appetite loss, unintentional weight loss, trouble swallowing, yellowing of the skin or eyes, fever that does not settle, or indigestion that keeps returning. A clinician can decide whether examination or testing is needed.

Ask what might connect your appetite change with the indigestion, whether any medicine could be contributing, which warning signs matter for you, and how to maintain fluids and food while symptoms continue.
