Loss of appetite, stomach pain and fatigue

The location and pattern of pain help guide assessment. Gastritis or peptic ulcer can cause upper abdominal discomfort and nausea, while gastroenteritis often causes cramping with vomiting or diarrhoea. Hepatitis A may present with tiredness, poor appetite, nausea, and later yellowing of the skin or eyes. COVID-19 and influenza can reduce appetite during a broader illness. Depression can present with low appetite and fatigue, although new abdominal pain still deserves attention.

These symptoms do not identify one diagnosis on their own. Note whether pain follows meals, whether fever or bowel changes occur, and whether the fatigue is improving or becoming more limiting.

Rest, take frequent sips of fluid, and choose small bland or nourishing meals as tolerated. Avoid alcohol and foods that clearly worsen the pain. Do not take leftover antibiotics or anti-inflammatory painkillers without advice, since some medicines can irritate the stomach. Arrange a clinical review if the symptoms persist, recur, or interfere with normal eating and activity. Bring a list of medicines and a record of pain, temperature, stools, vomiting, and urine.

Seek urgent care for sudden or severe abdominal pain, a rigid or swollen abdomen, repeated vomiting, fainting, confusion, blood in vomit, black stools, or inability to keep fluids down. Prompt assessment is also needed for yellow skin or eyes, very dark urine, worsening weakness, or signs of dehydration. If fatigue comes with chest pain, breathing difficulty, or collapse, call emergency services.

Where might the pain be coming from? Do I need tests for infection, liver problems, or stomach irritation? Could a medicine be contributing? What should I eat and drink while symptoms continue? Which changes mean I should seek urgent care?
