severe nutritional deficiencies are typically associated with crohn's disease which affects the small intestine where most nutrients are absorbed. because ulcerative colitis affects the large intestine it can cause severe and sometimes bloody diarrhea putting patients at risk for iron deficiency and anemia. you can measure your iron level with a simple blood test. ulcerative colitis can also deplete stores of folate. that's especially dangerous for women of child-bearing age since folate deficiency is linked to birth defects. fluid loss from diarrhea can also cause electrolyte imbalances.
do i need to be concerned about nutritional deficiencies in my diet because of ulcerative colitis?
