Abstract

Diabetes and hyperglycemia are common features of mitochondrial disorders. This study investigates the frequency of non-iatrogenic hypoglycemia in individuals with these disorders. Of 116 patients, 22 (18.97%) experienced at least two episodes of hypoglycemia. This rate is significantly higher (p < 0.05) than the 6% seen in the non-diabetic, general population. Neonatal readings were 30 mg/dL lower than non-neonatal readings. As hypoglycemia appears to occur frequently in individuals with mitochondrial disorders, with lower blood glucose levels in the neonatal period, early and continued monitoring of blood glucose is necessary. Also, mitochondrial disorders should be considered in cases of recurrent hypoglycemia.
