The symptoms include:
- Loss of appetite
- Nausea and vomiting
- Abdominal pains and cramps
- Blood in your stools
Stool testing is done in certain circumstances when the doctor suspects something other than viral gastroenteritis, such as food poisoning. Blood samples might also be taken to check for evidence of dehydration.
Most cases of gastroenteritis do not require treatment and the symptoms will improve in a few days, although medication may be recommended if the condition is severe. Antidiarrhoeal medications are sometimes used to reduce diarrhoea. Anti-emetic medications, such as metoclopramide, are sometimes used to help prevent or reduce vomiting. Treatment in hospital will involve administering fluids and nutrients directly into a vein (intravenously).
