Estrogen enhances insulin sensitivity. When estrogen swings or drops, your cells can become slightly 'deaf' to the signal of insulin. This means your blood sugar levels stay higher for longer, leading to energy crashes and cravings.
The Hangry Phase
If you find yourself snapping at family before dinner, your blood sugar might be plummeting. Stabilizing glucose is the first step to managing perimenopausal mood swings.
