#AskTheExpert hi anirav has loosies since 2 days he is bot eating at all n had vomiting on Saturday. he doesn't has any fever. is it heat or should i get him tested?

A. hi dear When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.
