The most common type of diarrhea with a watery stomach is various types of enteritis. For example, in summer diarrhea, it is common to have a bacterial infection, and in case of fall diarrhea, it is common to have a rotavirus infection. In the case of dilute watery stools with green color in infants and children, indigestion should be considered and can be treated with medication to help digestion, such as oral stomachic and dietary tablets. If the stools are frequent, you can give oral treatment with Simethicone. In adults with dilute watery stools, rotavirus infection should be considered, some patients are self-limiting, but most patients have more frequent stools. If the stool is yellowish in color and has a strong smell, this condition should be considered damp-heat diarrhea, which is often treated clinically with Ge Gen Scutellaria Tang with Wu Ling San. If the patient has cold-damp diarrhea, the main symptoms are clear and thin stools like water, accompanied by fever and coldness, light mouth and no thirst, or headache and body pain, with a pale tongue and white tongue coating, it can be considered cold-damp diarrhea and should be treated with Huoxiang Zhengqi San or Huoxiang Zhengqi Shui. If you have diarrhea more frequently, 10 times a day, with loss of appetite, nausea and vomiting, you should consider electrolyte disorders and suggest that you check blood, stool and electrolytes. If there is hypokalemia or hyponatremia, rehydration therapy is recommended. Therefore, if you see dilute watery stool, you should not just give the patient medication. It is recommended to go to a regular hospital and treat the patient according to the results of the examination.
