No appetite after food poisoning: recovery guidance

Nausea, abdominal cramping, diarrhoea and tiredness can make food unappealing after vomiting has stopped. Appetite should return gradually as these symptoms settle; there is no need to force a full meal straight away.

Being able to keep fluids down, passing urine normally and noticing less nausea or diarrhoea are reassuring signs of recovery. Appetite can lag behind these improvements because the digestive tract remains sensitive and the body is still replacing lost fluid and energy.

Continuing vomiting, frequent watery stools or fever can prolong poor intake. Dark urine, a dry mouth, dizziness on standing, unusual sleepiness or passing very little urine suggest dehydration rather than appetite loss alone.

Take small, frequent sips of water or oral rehydration solution. If nausea returns, pause briefly and try smaller amounts. Rehydration solution replaces salts as well as fluid, which can be helpful after vomiting or diarrhoea.

When fluids stay down, try small portions of familiar, easy-to-tolerate foods such as soup, rice, toast, potatoes, bananas or plain yoghurt. Increase the amount according to comfort. Rich, greasy or very spicy food, alcohol and large meals may aggravate nausea or cramping during early recovery.

Continue any prescribed medicine as directed. Do not start an anti-diarrhoeal drug or leftover antibiotic without checking with a clinician or pharmacist, especially when fever or blood in the stool is present.

Seek urgent medical help if you cannot keep fluids down, faint, become confused, have severe or worsening abdominal pain, vomit blood, pass black or bloody stool, or develop signs of marked dehydration.

Contact a clinician promptly if fever persists, diarrhoea is not easing, appetite does not begin to return as other symptoms improve, or weakness prevents normal activity. Babies, older adults, pregnant people and anyone with reduced immunity, kidney disease or another significant condition should seek advice earlier because fluid loss may affect them more quickly.

Tell the clinician when the illness started, what you can drink or eat, how often you are urinating, and whether there is fever, blood, severe pain or recent travel. Ask whether you need an examination, a stool test, supervised rehydration or changes to your regular medicines while intake is reduced.
