Celiac disease (also called gluten-induced enteropathy) is an intestinal disorder that results from intolerance to gluten, a protein found in wheat, oats, barley, and rye.  Eating gluten containing foods damages the small intestine and makes it impossible for sufferers to absorb nutrients properly, including vitamin A, which the eyes need to function in low light conditions.

Celiac disease may not cause symptoms in some people. However, people with the condition may report history of frequent, loose, watery stools; pale, foul-smelling, bulky stools; abdominal pain, gas and bloating; weight loss; fatigue; canker sores; muscle cramps; delayed growth or short stature; bone and joint pain; seizures; painful skin rash; and infertility. In addition to physical symptoms, there may be emotional disturbances including feelings of anxiety and depression.

Celiac disease can also cause nightblindness. Trouble in the intestinal tract can mean the body does not absorb enough essential vitamin A (a key component of beta-carotene and the reason your mom told you that carrots would help you eye sight).  Therapeutic doses of vitamin A can help correct the problem.   The best form of vitamin A is known as palmitate, taken in a daily dose of 15,000 international units.

Vitamin A deficiency is uncommon in the U.S., but it affects many people in the developing world.  One of first symptoms of a vitamin A deficiency is night blindness, which, if untreated can develop into full scale blindness.  According to the World Health Organization Report on Vitamin A Deficiency, night blindness is estimated to affect 5.2 million preschool-age children and 9.8 million pregnant women around the globe.

Writing on a recent case in The Lancet, doctors who treated a pregnant woman who came to the emergency room after several weeks of progressive sight loss described this particular case, “Vitamin A deficiency can be secondary to poor intestinal absorption due to weight loss surgery, Crohn’s disease or pancreatic dysfunction. Our patient had anorexia nervosa and had limited her diet to white onions, white potatoes, and red meat for the past 7 years.”

We usually recommend taking vitamin A in the form of beta-carotene, which converts to vitamin A with a small amount of fat in the diet. Food sources of vitamin A include: yellow and orange vegetables (including yams, carrots, mangoes, cantaloupe, apricots, butternut squash,and sweet potatoes), and asparagus, spinach, kale, bok choy.  If you wish for additional supplementation, the recommended dose is approximately 15,000 to 25,000 I.U. of beta-carotene daily.
