The most common cause of diarrhoea and vomiting are infections lasting 3-7 days which get better on their own. Often antibiotics make things worse by killing the friendly bacteria in your gut.
The most important thing is to maintain fluid intake, especially in the young and elderly. Consider sugary drinks like apple juice or black currant. Rehydration salts and loperamide can help and are available over the counter. Fever is due to the body fighting infection and is to be expected. Paracetamol helps with fever.
If you are unable to keep fluids down over a 24 hour period, have severe abdominal pains, pass blood or are very unwell, contact your GP.
If you are a diabetic patient needing insulin and vomiting, contact your GP or Diabetes Nurse if your blood sugars are high or you don’t know how to manage your insulin dosing when ill.
When to seek help
If your condition is not improving over 3 days, or you develop severe abdominal pains, pass blood or become very unwell, contact your GP.
