Vitamin and Zinc Status Pretreatment and Posttreatment in Patients With Inflammatory Bowel Disease
The authors report no conflicts of interest.
ABSTRACT
Vitamin deficiencies are common in inflammatory bowel disease. Here we present 5-year follow-up data of 61 patients. No folate or vitamin B12 deficiency was identified throughout the study. A daily multivitamin supplement was sufficient to replete 100% of vitamin A–deficient and vitamin E–deficient patients. A total of 52% of vitamin D–deficient patients corrected, but 15% who had normal vitamin D levels at diagnosis developed deficiency. A total of 63% of zinc-deficient patients normalized their zinc status, but 15% developed zinc deficiency at follow-up despite supplementation.
