When stool properties change, it can be seen in intestinal tumors, inflammation, dysfunction, and perianal disease.
When tumors occur in the intestine, such as colon and rectal cancer, the stools can become thinner and more frequent. Some patients may have alternating diarrhea and constipation, blood in the stool or bleeding after the stool, and an unsmooth stool surface.
When ulcerative colitis occurs, diarrhea, such as bloody diarrhea, bloody stools, or watery stools, may occur. Pus and mucus may be mixed in the stool. The number of stools increases significantly and may be accompanied by abdominal pain, vomiting, and urgency. The diagnosis can be clarified by fiberoptic colonoscopy.
Chronic inflammation of the intestine can also cause changes in stool characteristics, with increased frequency of stools and irregularities in stools. Colonoscopy and routine stool and stool culture tests can be done to facilitate the diagnosis of the disease.
Gastrointestinal dysfunction can also cause abnormal stools, such as increased frequency of bowel movements or poor bowel movements, as well as diarrhea and constipation.
