What is the reason for frequent diarrhea?

Diarrhea is often considered as diarrhea. Common causes of diarrhea include food poisoning, intestinal infection, intestinal tumor, etc., as follows:

Diarrhea symptoms can be seen clinically in patients with food poisoning. Diarrhea symptoms caused by food poisoning are usually caused by the intestinal mucosa of patients affected by food toxins. The intestinal mucosa secretes a large amount of liquid, resulting in increased mechanical intestinal motility. Frequent diarrhea can also be seen clinically in patients with intestinal infection. The formation of this phenomenon is related to factors such as bacterial invasion of intestinal tract and increased intestinal exudation. In addition, if the patient has tumors in the colon and rectum, diarrhea symptoms can be caused due to impaired colorectal function and inability to absorb fecal moisture.
