What does fever feel like with food poisoning?

Fever is a common presentation of Food Poisoning and can feel like warmth, chills, sweating, weakness, headache, or body aches. It often occurs alongside nausea, vomiting, loose stools, stomach cramps, or reduced appetite. Take your temperature rather than relying only on how your skin feels. The combination of fever and digestive symptoms can make fluid loss harder to notice until thirst, dizziness, or reduced urination appears.

Food poisoning can follow food or water contaminated with an infectious germ or toxin. Fever reflects the body’s response, while vomiting and diarrhoea help explain weakness and dehydration. Symptoms may begin after a shared meal, but timing varies and fever can also occur with other infections. Blood in the stool, severe pain, or symptoms affecting several people after the same meal should be mentioned to a clinician.

Take frequent small sips of water or an oral rehydration drink, especially after vomiting or a loose stool. Rest and return to plain foods gradually as appetite improves. Wash hands carefully and avoid preparing food for other people while you have vomiting or diarrhoea. Do not take anti-diarrhoeal medicine without advice if you have fever or blood in the stool, and ask a pharmacist about medicines that are suitable for you.

Seek prompt medical care for severe or worsening abdominal pain, blood or black material in stool, repeated vomiting that prevents drinking, confusion, fainting, or signs of dehydration such as very little urine and marked dizziness. Get advice sooner for a young child, an older adult, pregnancy, or a condition that weakens immunity. Emergency help is needed for collapse or difficulty staying awake.

Ask whether you need testing or treatment, how to replace fluids, and which medicines are safe. Tell the clinician when symptoms began, what you ate, how often you have vomited or passed stool, your temperature reading, and whether anyone else became ill.
