Watery diarrhoea from food poisoning

When the bowel moves fluid through too quickly, stools may become loose and watery. Food poisoning can inflame the gut or change how it handles water. Cramping, nausea, vomiting, and fever may accompany diarrhoea. The appearance of a stool does not identify the germ or prove that food was responsible; recent meals and exposures provide context.

Fluid loss can lead to dry lips, thirst, dizziness, weakness, dark urine, or less frequent urination. Blood or black stool is not a typical feature to manage casually and should be discussed urgently.

Drink often, choosing small amounts of water, broth, or oral rehydration solution. Oral Rehydration Therapy supplies water and salts in a balanced mixture. Eat small portions when hungry and avoid alcohol, very fatty foods, and drinks that make symptoms worse. Wash hands after using the bathroom and before eating; clean shared bathroom surfaces and avoid preparing food for others while symptoms continue. Ask a clinician before using medicines that slow diarrhoea, especially if you have fever or blood in the stool.

Get urgent help for fainting, confusion, severe dehydration, blood in the stool, severe abdominal pain, or repeated vomiting that prevents drinking. Contact a clinician if symptoms are worsening, do not begin settling, or affect a young child, older adult, pregnant person, or someone with a long-term illness. IV Fluid Therapy may be used when oral replacement is not possible or sufficient.

How much fluid should I try, and is oral rehydration suitable for me? Do my stool changes or other symptoms require testing? Which medicines should I avoid?
