Diarrhea

Diarrhea is a common clinical symptom that can be caused by various diseases. Diarrhea generally refers to an increase in the number of daily bowel movements or frequent defecation, with loose stools or stools containing mucus, pus, blood, or undigested food and other pathological contents. Diarrhea is often accompanied by symptoms such as urgency, anal discomfort, and incontinence. Diarrhea is generally divided into two categories: acute diarrhea and chronic diarrhea. The former refers to diarrhea with acute onset, short duration, and a course within 2 to 3 weeks. The latter generally refers to diarrhea lasting more than 2 months or recurrent diarrhea with an interval of 2 to 4 weeks.
