The symptoms of fever and diarrhea with vomiting are usually caused by acute enteritis, which can be triggered by unclean diet, cold and flu, and cold, resulting in vomiting, fever, diarrhea, and sometimes abdominal pain. In addition to acute enteritis, you should also be alert to the possibility of food poisoning, especially mushroom food. Once food poisoning occurs, it may also cause vomiting and diarrhea, as well as fever and abdominal pain. In addition to this, if chronic gastroenteritis has an acute attack, the above symptoms may also occur. It is recommended that the patient drink light saline in time to avoid electrolyte disorders caused by dehydration and to exclude the possibility of food poisoning as soon as possible after the onset of such symptoms. In the case of acute gastroenteritis, oral antidiarrheal medication should be taken promptly, and if the situation is urgent, medical attention must be sought promptly.
