your doctor will take a careful history including asking you questions about what you have eaten. you'll be asked to describe your symptoms and how long you’ve had the symptoms. if dehydration is severe you may be given fluids intravenously. don't expect an antibiotic until the bacteria has been identified. antibiotics are given for certain bacteria such as shigella but can worsen infections caused by other problems. your doctor may also give medications called antiemetics to stop vomiting. in general doctors avoid giving antidiarrheal medicine if they suspect the infection is caused by a toxin.
