Estrogen is secreted by the ovaries, which cease production at menopause. Estrogen protects against heart disease, stroke, osteoporosis, Alzheimer’s Disease and memory disorders. It protects against vaginal atrophy, urinary incontinence, and prevents symptoms of menopause, including hot flashes. Estrogen deficiency results in urogenital atrophy, incontinence, sagging skin in the breasts, increased skin wrinkles of the face, increased fatigue, depression, mood swings and decreased libido. It is of extreme importance that the estrogen prescribed be a natural estrogen and not a synthetic estrogen. The synthetic estrogens have been shown to be harmful. For optimal protection, natural estrogen supplementation should be balanced by natural progesterone supplementation. You do need estrogen! But it must be the right type of estrogen, maintained at optimal levels for maximum protection.
