The article focuses on the findings of a study that aims to determine whether the Turner syndrome (TS) is due to impaired glucose sensing or to a more fundamental cell defect. It notes that type 2 diabetes (T2DM) and impaired glucose tolerance (IGT) are common in TS. The researchers compared insulin responses to glucose and arginine in TS and age-matched control women.

The article discusses a study on the effect of growth hormone (GH) treatment on glucose tolerance in girls with Turner Syndrome (TS). It states that since GH is known to promote insulin resistance, it is expected to increase the propensity for impaired glucose tolerance. The glucose tolerance and insulin secretion were investigated by means of an oral glucose tolerance test (OGTT). The reason for the improvement of glucose tolerance in girls with TS is given.
