Advantages of hormone replacement therapy after a hysterectomy include fewer symptoms of menopause, lower risk of heart disease and an increase in bone density, explains WebMD. Disadvantages include complications with current medical problems, such as liver disease or breast cancer, and a higher risk of blood clots and other heart-related problems.
Benefits and risks with hormone replacement therapy change with age, according to WebMD. Women under 50 years old who have a hysterectomy with ovarian removal experience a higher risk of certain diseases in later life, such as dementia. There is evidence that estrogen in hormone replacement decreases such risks for younger women but increases the risks for older women. Hormone therapy also alleviates adverse sexual symptoms after a hysterectomy, such as vaginal dryness and pain during intercourse, according to Mayo Clinic. Only women who experience ovarian removal during a hysterectomy have a lower level of estrogen, making hormone replacement unnecessary in procedures that allow women to keep at least one ovary.
Hormone therapy is available in pill, spray, patch and other forms, explains Mayo Clinic. Some women use lower doses of hormone therapy, available in vaginal creams and rings, although low-dose versions may not have the same benefits as higher doses of estrogen.
