Which symptom is not typical of ulcerative colitis?

Weight gain is not a typical symptom of ulcerative colitis. In fact, the condition generally leads to symptoms that are associated with inflammation of the colon, often resulting in nutritional deficiencies and unintended weight loss. Patients with ulcerative colitis typically experience significant abdominal discomfort, frequent bloody diarrhea, and may also deal with nausea. As the disease progresses or during flare-ups, individuals may notice a marked decrease in their appetite and weight, rather than an increase. Therefore, weight gain does not align with the expected clinical presentation of ulcerative colitis, making it the correct choice among the options provided.
