Ulcerative colitis may lead to wasting, but this is an abnormal pathological state of the body and the term “normal” is incorrect. Ulcerative colitis can be caused by persistent intestinal dysfunction that affects digestion and absorption, leading to symptoms of malnutrition such as wasting, which is usually seen in people with severe or persistent disease. However, it should be noted that regardless of the specific clinical manifestations, the disease is an abnormal state of the body and cannot be judged as normal or not. It should also be noted that in addition to wasting, ulcerative colitis is more common in digestive manifestations such as diarrhea, mucopurulent blood stools and abdominal pain. Therefore, the specific diagnosis and treatment of this disease must be completed by a professional doctor, do not blindly judge and dispose of it by yourself, so as to avoid improper intervention and adverse consequences.
