If the diarrhea is caused by improper diet, there is a possibility of self-healing, but if it is caused by intestinal bacteria infection, it is generally difficult to self-heal and requires medication. The yellow water is mostly a sign of acute enteritis. If the patient eats too much fatty or cold food, the yellow water caused by this type of cause can usually heal itself after a few days after improving the diet. The symptoms of viral enteritis are relatively mild and may heal on their own, but enteritis caused by bacterial infection is relatively difficult to heal on its own. In case of yellow water, the patient can observe the situation and drink more plain water to prevent dehydration. If the symptoms of yellow water do not improve, or if the diarrhea is particularly serious, it is necessary to pay attention to it, and should promptly go to the gastroenterology department of the hospital to avoid delaying the condition, resulting in excessive water loss and causing shock. Patients with diarrhea should pay attention to keeping warm, especially the abdomen, not to get cold, and pay attention to adequate rest, and reduce the intake of greasy and coarse fiber foods.
