What does loss of appetite feel like with gastritis?

Gastritis is irritation or inflammation of the stomach lining. The discomfort may be a burning or aching feeling in the upper abdomen, sometimes with bloating, queasiness, or feeling full after only a small amount. Because eating can seem to worsen these sensations, you may stop looking forward to meals or leave food unfinished. Some people still feel hungry but find that nausea, indigestion, or an unpleasant taste makes eating difficult. Appetite changes alone cannot identify the cause; infections, medicines, reflux, stress, and other illnesses can also reduce appetite.

Try small, frequent meals rather than large portions, and choose foods that feel gentle for you. Sip fluids regularly, especially if nausea is present. Avoid alcohol and notice whether spicy, acidic, or fatty foods aggravate your discomfort. Do not stop a prescribed medicine without advice, even if you suspect it irritates your stomach. Arrange a medical review if the appetite change persists, keeps returning, or is accompanied by ongoing upper-abdominal pain.

Seek urgent medical help for vomiting blood, black or tar-like stools, severe or worsening abdominal pain, fainting, confusion, or inability to keep fluids down. Prompt assessment is also sensible if you are losing weight without trying, becoming unusually weak, or the reduced appetite is not settling.

Ask whether your symptoms fit gastritis, whether a medicine or infection could be contributing, and whether you need testing for stomach inflammation or another cause. Tell the clinician when the appetite change began, what foods trigger discomfort, and whether you have nausea, vomiting, dark stools, or weight change.
