If the patient has sudden vomiting and diarrhea in the middle of the night, first consider that the patient has digestive system diseases of different degrees, such as acute gastroenteritis or pancreatitis, cholecystitis. These circumstances will lead to this situation. It is necessary to quickly judge and send the patient to the hospital for treatment. If this happens in the middle of the night, in consideration of food poisoning, the patient can induce vomiting at home, such as drinking plenty of warm water or mineral water. Try to vomit out the food not completely absorbed in the gastrointestinal tract by picking the throat, and then send the patient to the hospital for diagnosis and differential diagnosis. If the patient continues to have the above symptoms, be sure to call for help. Send the patient to the hospital, but during the whole transfer process, make sure that the respiratory tract is unobstructed to avoid asphyxia, choking, etc. of foreign objects.
