Hormone replacement therapy is believed to have several benefits, including helping to ease symptoms of menopause such as hot flashes, night sweats, and vaginal dryness and discomfort caused by loss of estrogen. It is also believed to help prevent osteoporosis. Hormone replacement therapy is an especially important consideration for female patients who experience early menopause and have had their ovaries removed as they have a higher risk for osteoporosis, heart disease, Parkinson's, anxiety, depression, and early death. In addition, women with menopause symptoms or begin menopause at an age of more than 45, may benefit from hormone replacement therapy.
