Common Nutrient Deficiencies in People with Newly Diagnosed/Untreated Celiac Disease

When vitamins and minerals are not absorbed in the intestine, an individual may experience nutrient deficiencies. Diets low in vitamins and minerals may also cause inadequate nutritional intake.

  • Malabsorption of many nutrients, including iron, vitamin D, and zinc, are common in a person with newly diagnosed or untreated celiac disease.1
  • Even though celiac disease typically damages the upper part of the small intestine (duodenum), the entire small bowel can be affected.2 Vitamin B12, absorbed in the lower part of the small intestine, is a common deficiency seen in celiac disease.2
  • Carefully following a balanced, gluten-free diet can help fix low vitamin and mineral levels. It may also be necessary to take gluten-free vitamin and mineral supplements. Speak to your doctor or dietitians about your specific nutrient and supplement needs.
