Gastroenteritis describes a group of diseases affecting the stomach or part of the intestine. Symptoms are often diarrhoea , sickness and stomach-ache. Because the lining of the stomach is likely to be inflamed , medicines are often immediately vomited up.
Large quantities of water, orange juice or thin soup should be taken to the counter the effects of dehydration.
Consult your doctor if the symptoms persist for more than a day or, in the case of babies or young children, six hours.
