Colitis, Ulcerative

This photo was from a total colectomy done for clinically severe, intractable chronic ulcerative colitis. It shows a closer view of a longitudinal section through the colon wall. This demonstrates not only the angry red mucosa but also the tendency for the inflamed tissue to throw itself up into inflammatory pseudopolyps. Source: Ed Uthman, MD. Public domain.

What Is Ulcerative Colitis?

Ulcerative colitis is an inflammatory disorder of the colon characterized by continuous inflammation of the mucosa and submucosa usually with small ulcers, extending from the rectum and typically involving the distal colon, rectum, and anus and producing bloody diarrhea.

While the severity of ulcerative colitis varies among patients, iron deficiency anemia often develops due to blood loss especially when there are many bloody bowel movements in a day.

The onset of ulcerative colitis is most commonly in young adulhood.

Q: Is this disease painful?

A: Yes with the passage of stool.

Psychological stress and subsequent dysbiosis exacerbate ulcerative colitis.

Psychological stress activates multiple physiological processes aimed at maintaining balance within the body. These physiological processes also have the capacity to influence the composition of microbial communities in the digestive tract, and research now indicates that exposure to stressful stimuli leads to gut microbiota dysbiosis.1

While the relative abundance of many different bacterial types can be altered during stressor exposure, findings in nonhuman primates and laboratory rodents, as well as humans, indicate that bacteria in the genus Lactobacillus are consistently reduced in the gut during stress.2

Presently, ulcerative colitis cannot be cured. This condition has a course of remissions, when symptoms subside, and flares, when symtpoms get worse. Treatment is aimed to reduce flares and promote remission. In all cases, correction of dysbiosis improves the condition.

Ulcerative colitis is associated with increased incidence of cancer of the colon.3
