This condition is caused by an intestinal infection caused by an unclean diet, which is the diarrhea symptom of acute enteritis. Most patients can have a combination of nausea, vomiting, and abdominal pain at the same time, and this is when it is called acute gastroenteritis. Eating unclean things often leads to gastrointestinal bacterial infections, and this is when the intestinal flora becomes disturbed, so the symptoms of diarrhea can occur. General treatment is recommended to give probiotics to inhibit the reproduction of harmful bacteria, which can regulate the intestinal flora disorder. Commonly used probiotics include Clostridium typhimurium tablets, Bacillus coagulans, Bacillus subtilis capsules, etc. If there is also a combination of nausea and vomiting symptoms, it can be combined with acid-suppressing drug therapy such as omeprazole, lansoprazole, rabeprazole, etc. It is important to take a light diet and eat easily digestible food.
