Chapter 50: Estrogen and Progestins
Menopause
1. Estrogen Loss: Menopause is associated with a reduction in estrogen levels, which usually begins
around ages 51 to 52, with 95% of women experiencing menopause between ages 45 and 55.

alternating periods of amenorrhea and menstruation.
3. Cessation of Menstruation: Eventually, both ovulation and menstruation stop completely.

women, characterized by sudden skin flushing, sweating, and a sensation of uncomfortable warmth,

short-term memory loss. Some also report depression or increased anxiety.

and a hump. In osteoporotic women, fractures of the hip and wrist can occur from minor trauma.
