Abstract

Hypomagnesemia may arise from various disorders such as renal magnesium wasting, familial hypomagnesemia, inadequate intake and increased gastrointestinal loss. Hypomagnesemia and hypocalcemia were found in a month-old female patient with generalized tonic-clonic seizure. Twenty-four hour urine collection samples were used to assess renal magnesium wasting; fractional excretion of 24-hr urine magnesium was less than 1.45%, i.e., within the normal limits. The patient had no history of chronic diarrhea or failure to thrive, which supports the conclusion that intake was adequate. She had no family history of hypocalcemia, hypomagnesemia, or seizures. Here, we report a case of idiopathic hypomagnesemia.
