Ulcerative colitis can cause fatigue through several factors. Ulcerative colitis causes ulcers in the intestine which can bleed and cause the person to become anemic. Anemia can cause fatigue because of a lack of red blood cells which produce oxygen. Less oxygen means the body has to work harder to keep up with the same amount of work it used to do with normal oxygen. Ulcerative colitis can also cause nausea and decreased appetite, which can both lead to fatigue because the body isn't getting enough nutrients to fuel itself. Finally, patients with ulcerative colitis can be fatigued because of a lack of absorption vitamin B12 which is an essential nutrient in the formation of healthy red blood cells. Coupled with anemia, vitamin B12 deficiency can cause extreme fatigue. Treatment of fatigue in ulcerative colitis patients includes reducing ulcerative colitis flares (to reduce blood loss), and taking vitamin B12 shots if the patient is vitamin B12 deficient.
