2. Ulcerative Colitis
Ulcerative colitis is likely to show up as a more pinky, or tan colored blood. This may also be accompanied by pus or mucus and it is commonly associated with diarrhea, stomach pain, and loss of appetite. Ulcerative colitis is a condition that is a form of irritable bowel disease – like Crohn’s disease. It is not to be confused with an irritable bowel disorder, even though it shares many of the same symptoms.
UC is caused by inflammation in the colon. This occurs because of an infection, or because of autoimmune disease in most cases. The result is pain and discomfort in the area and the formation of ulcers that can then break open to cause the bleeding and the pus.
