• Problem: Lactose intolerance Common in newly diagnosed celiac disease patients; a temporary lactose-free diet, in addition to a lifelong gluten-free diet, may be necessary to heal intestinal villi, microscopic fingerlike projections that absorb nutrients in the small intestine.
  • Solution: Lactase enzyme drops or tablets, lactose-reduced dairy products, or nondairy milks.
  • Problem: Vitamin B12 deficiency
    Common in cases of extreme B12 malabsorption.
  • Solution A multivitamin with vitamin B12, or B12 injections (in some cases).
  • Problem: Bacterial overgrowth
    Typically associated with celiac disease due to intestinal villi damage.
  • Solution Probiotic therapy, which recolonizes the intestine with good bacteria. Cynthia Rudert, MD, an Atlanta-based gastroenterologist and CD expert, recommends probiotics found in supplements and yogurt (which contains very little lactose).
  • Problem: Osteopenia or osteoporosis
    Conditions common in both children and adults due to nutrient malabsorption.
  • Solution Calcium and vitamin D supplements, taken together in more than one dose. Calcium citrate is the best-absorbed form; calcium carbonate is more economical and needs to be taken with food.
  • Problem: Iron deficiency
    Common symptom of celiac disease.
  • Solution Anemia usually disappears upon adopting a gluten-free diet. However, short-term iron supplementation may be necessary, taken in lower doses or in a gluten-free multivitamin with iron. Take with vitamin C for highest absorbency.
  • Problem: Folate deficiency
    May occur in cases of folic acid malabsorption.
  • Solution: A multivitamin with folic acid.
