Signs of ulcerative colitis are recognized through tests performed by the physician. In mild ulcerative colitis, there is mucosal edema, erythema, and granularity. In moderate ulcerative colitis, mucus or pus is present. Spontaneous bleeding, erosions, and ulcerations are found in severe ulcerative colitis. 10 Redness, pits or ulcers, blood, pus, and polyps can be seen by examining the inside of the colon.
Polyps are deep ulcers that can leave mucosal islands.
Crypt abscesses are inflammatory cells seen around the crypts in the colon. The haustra appears flattened. The colon is narrower in some sections. Complications due to signs and symptoms are usually quite severe and can lead to hospitalization. Water and electrolytes can become imbalanced.
