Authors would like to demonstrate the beneficial effect of myo-inositol supplementation in a pregnant woman with insulin-dependent type 2 diabetes mellitus and polycystic ovary syndrome. Insulin and metformin treatment could not achieve normalization of glucose homeostasis for 3 years, and hypoglycemic episodes were frequent. Myo-inositol and folic acid supplementation added to the basic treatment resulted in improved glucose levels in 2 months. At this time she became pregnant. During pregnancy serum glucose levels still improved in the next 2 months. The amniotic membrane ruptured at the 19th gestational week, and pregnancy had to be finished. Developmental disturbances were excluded by the pathologist. She became pregnant again and gave birth to a premature male neonate at the 29th gestational week. The aim of the report was to demonstrate that myo-inositol supplementation may improve the efficacy of the therapy in type 2 diabetes mellitus. Orv. Hetil., 2017, 158(14), 541-545.
