What is Hormone Replacement Therapy?

Hormone therapy is sometimes called Hormone Replacement Therapy. A very basic explanation of hormone therapy is that it replaces female hormones that are naturally produced by your body, but due to some reason are at a deficient level. The therapy primarily replaces estrogen and sometimes progesterone that are lost during the menopause transition. Hormone therapy is a first-line therapy approved by the FDA for treating menopausal symptoms such as hot flashes, fatigue, night sweats, or vaginal dryness. The therapy may seem complicated, but discussing the basics of this therapy with your doctor can make things easier, as the benefits of this therapy outweigh the risks for HRT. Mainly, there are two types of Hormone replacement therapy:

Systemic Therapy

When pills, patches, gels, sprays, or vaginal rings are used to deliver the hormones throughout the body, this is known as systemic therapy. Systemic doses have a significant effect in affected areas as they are absorbed into the bloodstream at very high levels, which is appropriate for treating menopausal symptoms such as hot flashes.

Low-dose Therapy

It is also known as vaginal estrogen therapy for post menopausal symptoms such as vaginal dryness, urinary issues, or painful sex. This therapy is effective in both rebuilding and moisturising tissue and is administered into the vagina. The risks are far lower than with systemic therapy, as very little of it enters the bloodstream.

Benefits and Risks of Hormonal Replacement Therapy for Women

Several factors are responsible for deciding whether to use hormonal therapy and whether it could be a significant choice for many women. Factors such as health condition, age, treatment options, symptom severity, and cost of treatment can help in making the decision. Even though the benefits of this therapy outweigh the risks, it becomes crucial for us to know that taking this therapy under the supervision of a healthcare provider is extremely important. The risks linked with hormonal therapy include stroke, blood clots, and, in a few cases, it may also lead to uterine and breast cancer.

But there are plenty of benefits that include a substantial decrease in menopausal symptoms such as hot flashes, vaginal dryness, night sweats, and poor sleep. It also provides relief from urinary issues or painful intercourse. A standard dose of hormonal therapy also helps in preventing osteoporosis. The scientific evidence shows that women on hormonal therapy are at low risk of getting type-2 diabetes, and it also lowers their risk of cardiovascular disease if the therapy is started within 10 years of menopause.

It's crucial to understand that hormonal therapy may not be the right choice for every woman, but for most of them it could outweigh the risks, if taken under the supervision of a health care professional.
