Hipertiroidili Bir Hastada Hipokaleminin Nadir Nedeni: Gitelman Sendromu

Abstract

Hipokalemi sık görülen elektrolit bozukluklarından biridir. Azalmış potasyum alımı, hücre içine artmış potasyum geçişi, gastrointestinal sistemden ya da üriner sistemden artmış potasyum kaybı, ilaçlar gibi pek çok faktör hipokalemiye neden olabilir. Gitelman sendromu hipokaleminin eşlik ettiği nadir görülen otozomal resesif hastalıktır. Burada hipertiroidi nedeniyle tetkik edilirken Gitelman sendromu tanısı konulan bir olguyu sunduk.

A Rare Reason of Hypokalemia in a Hyperthyroid Patient: Gitelman Syndrome

Abstract

Hypokalemia is one of the commonly observed electrolyte disturbances. Many factors like decreased potassium intake, increased intracellular potassium influx, increased excretion from the gastrointestinal system or urinary tract, and drugs can cause hypokalemia. Gitelman syndrome is a rare autosomal recessive disease associated with hypokalemia. Here, we presented a case who was examined for hyperthyroidism and finally diagnosed as Gitelman syndrome.
