Loss of appetite for a week

A short illness can blunt hunger through fever, nausea, altered taste, tiredness, or changes in digestion. Stress and low mood may also affect appetite. Abdominal burning or pain can occur with gastritis or peptic ulcer disease, while vomiting and diarrhoea can occur with gastroenteritis.

The length of time matters, but it does not identify the cause by itself. Note whether you are losing weight, drinking normally, passing urine as usual, and managing everyday activities. A new medicine, dental problem, pregnancy, or ongoing pain may also be relevant.

Keep a simple record of meals, fluids, symptoms, medicines, and any weight change. Choose small, nourishing portions at regular times rather than waiting for hunger. Include foods with protein when tolerated, and sip fluids throughout the day. Gentle activity may help if you feel well enough.

Book a primary-care appointment if the appetite has not started to return, particularly if you have a long-term condition or take regular medicines. Do not start appetite stimulants or stop prescribed treatment without guidance.

Seek urgent care for severe or worsening pain, repeated vomiting, blood or black stools, confusion, fainting, breathing difficulty, or very little urine. Arrange prompt assessment for yellowing skin, persistent fever, marked weakness, unexplained weight change, or inability to manage normal activities.

Ask what causes fit your symptoms, whether your medicines or health conditions affect appetite, and whether you need an examination or tests. Bring your symptom and food record, and mention mood, sleep, bowel changes, pain, fever, and hydration.
