Menopause Hormone Therapy: Benefits and Risks

Menopause hormone therapy is neither a miracle for everyone nor universally dangerous. It is the most effective treatment for hot flashes and night sweats and can help some other menopause symptoms. Whether it is a good option depends on your symptoms, age, time since menopause, medical history, treatment type and preferences.

What does hormone therapy contain?

Systemic hormone therapy delivers estrogen throughout the body through tablets, patches, gels, sprays or other formulations. If you have a uterus, a progestogen is usually added to protect the uterine lining from the effects of systemic estrogen. People without a uterus may be able to use estrogen alone.

Low-dose vaginal estrogen mainly treats vaginal and urinary symptoms, such as dryness or pain with sex, with much lower systemic exposure. Its risk discussion is therefore different from that of systemic therapy.

What can it help?

Systemic therapy can reduce moderate to severe hot flashes and night sweats and may improve sleep when symptoms are waking you. It can prevent bone loss while it is being used. Some people also notice improvement in menopause-related joint discomfort or quality of life, although responses vary.

Local vaginal treatment can help genitourinary syndrome of menopause, which may include dryness, burning, pain with sex, urinary urgency or recurrent urinary symptoms.

Who often has the most favorable benefit–risk balance?

For many healthy people who have bothersome symptoms and start therapy before age 60 or within about 10 years of menopause onset, expert groups consider the benefit–risk balance favorable. This is not an automatic green light. A clinician still needs to review personal and family history, blood pressure, bleeding and other medicines.

Starting later can carry a different balance of risks. Continuing beyond age 60 or 65 is not automatically forbidden, but it should be periodically reassessed.

What are the possible risks?

Risks depend on the formulation, route, dose, duration and individual. Systemic therapy can increase the risk of blood clots and stroke in some circumstances. Combined estrogen–progestogen therapy is associated with a small increase in breast-cancer risk with longer use; estrogen-only therapy has a different risk profile. Unopposed systemic estrogen in someone with a uterus can increase endometrial-cancer risk.

Hormone therapy is not used to prevent heart disease or dementia. It may be unsuitable—or require specialist review—for people with a history of certain hormone-sensitive cancers, unexplained vaginal bleeding, previous blood clots, stroke, heart attack or significant liver disease.

Are “bioidentical” hormones safer?

Some regulated, approved products are chemically identical to hormones produced by the body. “Bioidentical” does not automatically mean safer. Major professional organizations generally prefer approved, quality-controlled products over custom-compounded preparations when an approved option is available, because compounded products may have less consistent dosing and less safety evidence.

What about nonhormonal options?

Effective nonhormonal treatments exist for hot flashes and sleep disruption, including certain prescription medicines and behavioral approaches. Vaginal moisturizers and lubricants may help milder vaginal symptoms. The best option depends on what you want to treat and your health history.

Questions to ask at an appointment

• Which symptom are we treating, and how will we judge benefit?
• Do I need systemic treatment or a local vaginal option?
• If I have a uterus, how will the uterine lining be protected?
• Does a patch or gel change my personal risk compared with a tablet?
• When should we review the dose and whether I still need treatment?
• Which new bleeding symptoms should I report?

When to seek medical care

Report any bleeding after menopause and any unexplained bleeding before starting therapy. Seek urgent care for symptoms that could indicate a blood clot, stroke or heart problem, such as sudden one-sided weakness, chest pain, coughing blood, or painful swelling in one leg.

The takeaway

Hormone therapy is a valid, evidence-based option for many people with bothersome menopause symptoms. A personalized discussion—not online extremes—should guide the product, route, dose and duration.
