Over time, the disease process in ulcerative colitis tends to progress toward what state?

• A. Chronic inflammation
• B. Spontaneous healing
• C. Fistula formation with abscesses
• D. Malignant transformation

Answer: (A)

Ulcerative colitis is defined by ongoing, chronic inflammation of the colonic mucosa that tends to persist over time, with relapses and remissions but a continuous inflammatory process underlying symptoms. Over the years, the disease more often remains in this chronic inflammatory state rather than spontaneously healing. Fistula formation with abscesses is not typical for ulcerative colitis (that feature is more characteristic of Crohn’s disease, which involves deeper, full-thickness tissue changes). While long-standing ulcerative colitis does increase the risk of colorectal cancer, that is a potential complication of chronic inflammation rather than the default state the disease tends toward. So the best description of how ulcerative colitis progresses is a persistent, chronic inflammatory process.
