Functional diarrhea includes diarrheal irritable bowel syndrome, in which patients may experience abdominal pain and diarrhea after every cold, stimulating, greasy and other stimulating diet, and it is a functional disease. Organic lesions such as gastrointestinal inflammation, enteritis, inflammatory bowel disease, ischemic enteritis, gastrointestinal polyps or tumors may lead to increased stool frequency. Secondly, some pancreatic diseases and gallbladder diseases may also lead to abnormal stool frequency. Finally, in addition to the digestive system itself, diseases outside the digestive system should also be considered, such as the patient is endocrine disease, hyperthyroidism can also lead to an increase in the number of stools.
