[Adult celiac disease presenting as tetany]

Tetany is a rare form of presentation of adult celiac disease. We present three patients with spontaneous episodes of tetania who were finally diagnosed of celiac disease. All were women. In two of them an unexplained chronic anemia was previously detected. The origin of tetania was severe hypocalcemia and hypomagnesemia. After intravenous restoration of calcium and posterior free gluten diet with supplements, clinical and biological remission was achieved. In the presence of isolated tetania or unexplained anemia resistant to treatment an adult celiac disease must be disclosed.
