Hormone Replacement Therapy (HRT): Pros and Cons

What is hormone replacement therapy?

Hormone replacement therapy, commonly called HRT, replaces hormones that fall during the menopause transition, mainly estrogen and, when needed, progesterone or another progestogen. It can be given as tablets, skin patches, gels, sprays or local vaginal treatments.

The goal is usually symptom relief, not simply to “replace hormones” because hormone levels have changed. HRT is most often considered for symptoms that interfere with daily life, including hot flashes, night sweats, sleep problems, mood changes and vaginal dryness.

The choice is not one-size-fits-all. A person who still has a uterus generally needs a progestogen alongside systemic estrogen to protect the uterine lining. Someone who has had a hysterectomy may be able to use estrogen alone.

In clinical practice, one issue is often missed: the conversation should be about the individual's symptoms and risks, not simply whether HRT is “good” or “bad.” The same treatment can have a very different risk-benefit balance in two people of the same age.

The pros of HRT

1. It is highly effective for hot flashes

For moderate or severe hot flashes and night sweats, systemic hormone therapy remains one of the most effective treatments available. These symptoms can affect sleep, concentration, work and everyday comfort, so improvement can be meaningful rather than cosmetic.

HRT can also improve other menopause-related symptoms, including sleep difficulties and vaginal dryness. Mood symptoms may improve when they are related to the menopause transition, although HRT is not a general treatment for depression.

2. It can protect bone health

Estrogen levels fall during menopause, and bone loss can accelerate during the early postmenopausal years. HRT can help prevent this loss and reduce the risk of some fractures.

That can be particularly relevant for people who experience early or premature menopause, although the appropriate treatment depends on the person's circumstances.

Doctar's guide to preventing osteoporosis also explains why bone protection becomes increasingly important after menopause.

3. Vaginal symptoms may respond well to local estrogen

Vaginal estrogen is different from systemic HRT. It delivers a low dose locally and is commonly used for vaginal dryness, soreness and some urinary symptoms after menopause. Because very little enters the bloodstream, its risk profile is different from systemic hormone therapy.

This distinction matters. Someone whose main problem is vaginal dryness may not need the same type of treatment as someone experiencing severe hot flashes throughout the day.

The cons and risks of HRT

1. Breast cancer risk needs careful discussion

The relationship between HRT and breast cancer is complicated because risk varies according to the type of therapy and how long it is used. Combined estrogen-progestogen therapy is associated with an increased breast cancer risk, while the evidence differs for estrogen-only therapy.

That does not mean everyone taking HRT will develop breast cancer. It does mean personal and family history should be discussed before treatment.

Doctar has also published a detailed explainer on menopausal hormone therapy and breast cancer, which can help readers understand why blanket statements about HRT can be misleading.

2. Blood clots and stroke are potential risks

Some forms of systemic HRT can increase the risk of blood clots. Oral estrogen is more strongly associated with this risk than estrogen delivered through the skin, such as patches, gels or sprays. Oral HRT can also slightly increase stroke risk.

The absolute risk for an individual may still be low, but a history of blood clots, stroke or other cardiovascular risk factors changes the discussion.

Doctar's HRT and heart disease guide covers this issue in more detail.

3. There can be troublesome side effects

Some people experience breast tenderness, headaches, nausea or unexpected vaginal bleeding after starting HRT. These effects are often mild and may settle, but persistent or heavy bleeding should be assessed by a healthcare professional.

Finding the right type of HRT can take some adjustment. Treatment may need to be reviewed if symptoms do not improve or side effects continue.

4. HRT is not a general anti-ageing treatment

This is where menopause marketing can get ahead of the evidence. HRT can be very useful for specific symptoms and for bone protection, but it should not be presented as a universal way to prevent ageing, dementia or heart disease.

ACOG advises against using menopausal hormone therapy solely to protect against heart disease, and current evidence does not establish HRT as a dementia-prevention treatment.

Who may need extra caution?

HRT may not be appropriate, or may require specialist input, for people with certain histories, including breast, ovarian or uterine cancer, previous blood clots, untreated high blood pressure or liver disease. The decision should be individualized rather than based on age alone.

Age and timing also matter. The balance between benefits and risks can change as someone gets older or further away from menopause. That is why treatment should be reviewed periodically rather than continued automatically.

HRT is not the only option

Not everyone wants HRT, and not everyone can safely use it. Non-hormonal medicines, cognitive behavioural therapy and lifestyle measures may help manage particular menopause symptoms.

For example, regular physical activity and strength training can support bone and muscle health. Cooling strategies, sleep habits and avoiding individual hot-flash triggers may also help some people.

Doctar's menopause and amenorrhea explainer can also help readers understand why missing periods should not automatically be assumed to be menopause.

Hormone testing is not routinely needed before starting HRT for typical menopause symptoms. A clinician can often make the decision from symptoms, menstrual history and medical history.

What should you ask your doctor?

A useful appointment is less about asking, “Should I take HRT?” and more about asking, “What are my options, and which risks matter most for me?”

Discuss your symptoms, age, stage of menopause, uterus status, personal and family history of breast cancer, history of blood clots or stroke, blood pressure and other medicines. Ask whether systemic or local treatment makes more sense and how the treatment will be reviewed over time.
