What menopause and perimenopause are

Menopause is the point 12 months after a person's final menstrual period, when the ovaries have largely stopped producing estrogen. In the United States it happens on average around age 51. The years of fluctuating hormones leading up to it are called perimenopause, and this transition is often when symptoms such as hot flashes, night sweats, irregular periods, and sleep or mood changes are most noticeable.

Not everyone needs treatment. Many people manage the transition with lifestyle measures or non-hormonal options. For those with bothersome symptoms, hormone therapy is one option to discuss with a clinician, alongside its benefits and risks.

What hormone therapy is and how it works

Menopausal hormone therapy replaces estrogen that declines around menopause; people who still have a uterus also take a progestogen to protect the uterine lining from the effects of estrogen alone. According to The Menopause Society, hormone therapy remains the most effective treatment for bothersome vasomotor symptoms (hot flashes and night sweats) and for the genitourinary syndrome of menopause, and it has been shown to help prevent bone loss.

Hormone therapy does not stop or reverse aging, and it is not a wellness or anti-aging product. Its established role is symptom relief and bone protection in appropriate candidates, used at the lowest effective dose with periodic re-evaluation by a clinician.

Types of hormone therapy

Estrogen-only vs. combined therapy

People without a uterus may be prescribed estrogen alone, while those with a uterus typically receive estrogen plus a progestogen to lower the risk of uterine (endometrial) cancer.

Systemic vs. local

Systemic estrogen—pills, patches, gels, or sprays—circulates through the body and treats hot flashes and protects bone. Low-dose vaginal (local) estrogen mainly treats vaginal dryness and genitourinary symptoms with little absorption into the bloodstream, and may be an option for some people who cannot use systemic therapy.

FDA-approved vs. compounded "bioidentical"

Many FDA-approved products use bioidentical hormones such as estradiol and micronized progesterone. Custom-compounded "bioidentical" hormones, by contrast, are generally not FDA-approved. The FDA, ACOG, and The Menopause Society advise that compounded preparations should not be used routinely when an FDA-approved option exists, because they are not tested the same way for purity, dose consistency, safety, or effectiveness.

Evidence-based benefits

• Most effective treatment for moderate-to-severe hot flashes and night sweats
• Relief of genitourinary symptoms such as vaginal dryness and discomfort
• Helps prevent bone loss and fracture in appropriate candidates
• Benefits and risks are individual and should be weighed with a clinician

Note: These benefits are documented in clinical guidance for symptom relief and bone protection. Hormone therapy is not approved or recommended to prevent heart disease, dementia, or other chronic conditions.

Risks and who should not use it

Hormone therapy carries risks that differ by type, dose, route, duration, and timing. Depending on the regimen and the person, these can include blood clots, stroke, and—with long-term combined therapy—a small increase in breast cancer risk. Risk generally rises with older age and starting therapy many years after menopause.

Systemic hormone therapy is generally not recommended for people with a history of breast cancer or certain other hormone-sensitive cancers, blood clots (deep vein thrombosis or pulmonary embolism) or clotting disorders, stroke or heart attack, liver disease, or unexplained vaginal bleeding. Only a clinician who reviews your full history can determine whether hormone therapy is safe for you.

Why timing matters

When the Women's Health Initiative trials were first reported in 2002, they raised alarm about hormone therapy, but the participants were on average about 63 years old—older than most people starting therapy for menopause symptoms. Later age-stratified analyses showed that the benefit-risk balance is more favorable for healthy people who begin therapy before age 60 or within about 10 years of menopause, and less favorable when started later. This "timing" consideration is now central to how clinicians individualize decisions.

How online HRT services work

Telehealth providers typically begin with an intake questionnaire and a virtual visit with a licensed clinician. Many arrange lab work or review your history before deciding whether a prescription is appropriate, then ship medication or send it to a pharmacy. Quality varies: look for genuine clinician oversight, appropriate lab testing and follow-up, clear pricing, and transparency about whether products are FDA-approved or compounded.

Is hormone therapy right for you?

If menopause symptoms are affecting your sleep, mood, or daily life, hormone therapy is one of several options worth discussing. Whether it is appropriate depends on your symptoms, age, time since menopause, and medical history—not on a quiz or marketing alone. Use these comparisons to prepare questions, then make the decision together with a qualified clinician who can weigh your individual benefits and risks.
