Diarrhea is a common symptom, which means that the frequency of bowel movements significantly higher than the frequency of usual habits. The fecal is thin, the water is increased, the daily defecation is more than 200g, or contains undigested food or pus and mucus. Diarrhea is often accompanied by symptoms such as the urgency of bowel movements, anal discomfort, and incontinence.
A normal person has about 9L of liquid per day entering the gastrointestinal tract, and the water is absorbed through the intestines, and finally the water in the feces is only about 100 to 200 ml. If the amount of fluid entering the colon exceeds the absorption capacity of the colon or (and) the absorption capacity of the colon is reduced, it will result in an increase in the amount of water excreted in the feces, resulting in diarrhea.
Clinically, according to the length of the disease, diarrhea is divided into acute and chronic. The incidence of acute diarrhea is acute, and the course of the disease is within 2 to 3 weeks, most of which are caused by infection.
