Hot Flashes… one of the primary symptoms associated with menopause in industrialized countries. Although there is no empirical proof of the cause for hot flashes the following explanation sounds reasonable:
At menopause, estrogen levels fall and progesterone levels are usually already low. An area in the brain’s hypothalamus (the GnRH Center) monitors estrogen and progesterone levels. When levels of these hormones decline:
In addition to hot flashes, the heightened activity of the hypothalamus can cause mood swings, fatigue, feelings of being cold, and inappropriate responses to other stressors. Many women will have symptoms of hypothyroidism despite normal thyroid hormone levels.
