For writer and speaker Amber Tresca, ulcerative colitis — an intestinal disorder — meant planning every moment of her life around one question.

That meant no theme parks with lines. No jobs with long commutes. No shopping trips downtown, she told Northeastern Global News.

Ulcerative colitis, or UC, the condition that Tresca has, is one of several inflammatory bowel diseases (IBDs), Northeastern biology professor Emeka Okeke explained.

The main types of autoimmune intestinal disorders are Crohn’s disease, which can affect any part of the digestive tract, and ulcerative colitis, which targets the large intestine.
