Diet and Nutrition in Crohn Disease (cont.)

Should I take vitamins if I have Crohn's disease?

Your need for vitamin and mineral supplements depends on several factors:

  • your diet,
  • which parts of your digestive tract are affected, and
  • whether you have had surgery on your small intestine.

 The most common vitamin deficiencies are vitamins D and B-12, and the most common mineral deficiencies are iron, calcium, potassium, and magnesium. You will need to take folic acid if you are taking an immunosuppressant such as azathioprine (Azasan, Imuran) as it reduces the absorption of folic acid. Talk to your health-care professional about taking supplements.

Can my medication affect my diet?

Patient Comments

Some medications used to treat Crohn's disease, such as sulfasalazine (Azulfidine, Azulfidine EN-tabs, Sulfazine), can interfere with absorption of nutrients from food. Certain medications taken for other medical conditions also can affect levels of vitamins and minerals in the body. Ask your health-care professional to review all of your medications.
