Te Hormonal Foundation of Glucose Variability

Te 28-day menstrual cycle (with normal variations spanning 21 to 35 days) is divided into diment al eras. Te folicular phase begins on tha firtt day of menstruation and lasts until ovulation. Te luteol phase spans from ovulation to te start of te next period. Each phase exerts unique pressures on glucosi consolidam, primarily controgh thactions of estrogen and progesterone on insulin signaling.

Progesterone and Insulin Resistance

After ovulation, thee corpus luteum sekres progesterone, a accore essential for mainting a potential gravestrancy. Progesterone is a natural insulid antagonistt. It reduces GLUT4 activity and can lead to eventant insulin resistance. This effect is mogt pronuced in thee mid- tolate luteol phase (days 19-28). For many women, this results in fasting and postprandial glukelas that can be dewer 10-30 mg / d hier thhase.
