Vitamin A Deficiency
vitamin A deficiency is common
in celiac disease.
Vitamin A deficiency can develop in
celiac disease in the following ways. Upper digestive
problems, such as low stomach acid, can fail to dissolve
vitamin A out of food sources. Protein deficiency impairs
absorption transport through the intestinal lining while fat
malabsorption impairs vitamin A absorption into the lymph.
Finally, the liver cannot mobilize stored vitamin A to
maintain adequate blood levels when blood protein and zinc
levels are low.
Vitamin A deficiency can persist or
develop after diagnosis and treatment with a gluten-free
diet if the diet does not include adequate amounts of
vitamin A, protein, zinc and fat.
