Insulin‐secretion capacity in normal glucose tolerance, impaired glucose tolerance, and diabetes in obese and non‐obese Japanese patients

Aims/Introduction: Pronounced reduction of insulin secretion in response to a rise in glucose level has been reported in Japanese patients compared with Caucasian patients, but the mean body mass index (BMI) is also lower in Japanese patients. As BMI is a determinant of insulin secretion, we examined insulin-secretion capacity in obese and non-obese Japanese patients. Using the oral glucose tolerance test (OGTT), we estimated the...
