Some common side effects of hormone replacement therapy (HRT) are stomach upsets, headaches, vomiting, bloating, vaginal spotting or bleeding, breast swelling and retaining fluid in different areas of the body. Although rare, there can also be more serious side effects, such as double vision, severe depressive states, fevers and the skin acquiring a yellow color, as noted by MedlinePlus. For a woman going through menopause, hormone replacement therapy can help with the troublesome symptoms associated with the changes occurring in her body.
Hormone replacement therapy involves women taking medications that contain estrogen. The medication can also contain the hormone progestin, as stated by MedlinePlus. During menopause, there is a reduction in the amount of estrogen that a woman's body can produce. This can lead to symptoms such as hot flashes, sweating and vaginal dryness.
Women with conditions such as blood clots, breast or uterine cancer, or heart disease should not use hormone replacement therapy, according to WebMD. Additionally, a large clinical trial showed that there are risk factors associated with using HRT. This study on the HRT combination medication of estrogen and progestin showed that it can increase the risk factor for heart disease, blood clots, breast cancer and stroke, as stated by Mayo Clinic.
