Glucose Tolerance During the Menstrual Cycle

Oral glucose tolerance tests were carried out at weekly intervals in thirteen young women and six young men. There was a greater variation in response by the young women compared to the young men. This greater variation was due to altered responses during different phases of the menstrual cycle. It is suggested that the fluctuations in the oral glucose tolerance test during the menstrual cycle may be secondary to alterations in gastric activity.
