Can Celiac Disease Cause B12 Deficiency?

Yes, celiac disease can lead to vitamin B12 deficiency. Celiac disease is an autoimmune disorder where the ingestion of gluten triggers an immune response, damaging the small intestine’s lining and affecting nutrient absorption.

Vitamin B12 (cobalamin) is absorbed in the small intestine, primarily in the ileum. In celiac disease, the damage to the intestinal lining can interfere with the body’s ability to absorb various nutrients, including vitamin B12. As a result, individuals with untreated or poorly managed celiac disease may experience deficiencies in several vitamins and minerals, including B12.

A lack of adequate absorption of B12 can lead to various symptoms associated with a deficiency, such as fatigue, weakness, anemia, tingling sensations in the hands and feet, difficulty maintaining balance, and cognitive issues.

Management of celiac disease typically involves adhering to a strict gluten-free diet to allow the intestinal lining to heal and improve nutrient absorption. However, in cases of severe deficiencies or malabsorption, healthcare providers may recommend B12 supplements or injections to address the deficiency until the intestine heals sufficiently to absorb nutrients properly.

If you suspect a B12 deficiency or have concerns about nutrient absorption due to celiac disease or any other condition, it’s essential to consult with a healthcare professional for proper evaluation and guidance on managing both the underlying condition and any associated deficiencies.
