HRT explained: benefits, risks and options for menopause
Hormone replacement therapy is the most effective treatment for menopause symptoms. What HRT is, the forms available, and an honest look at benefits and risks.
Reviewed by Emma Carter, Senior Health & Nutrition Editor
HRT is the most misunderstood part of menopause care. Old headlines still make many women wary, yet for a lot of women it is the single most effective way to feel better. Here is a clear, honest overview to take into a conversation with your doctor.
What HRT is
Hormone replacement therapy tops up the hormones that fall during menopause, mainly estrogen and usually progesterone. Replacing estrogen eases the symptoms driven by its decline. The progesterone is there to protect the lining of the womb, which is why women who still have a womb take both, while those who have had a hysterectomy can usually take estrogen on its own.
What it helps with
HRT is the most effective treatment for hot flashes and night sweats, and it is recommended as the first-line option for these symptoms in women without contraindications (North American Menopause Society). It also commonly helps with:
- Broken sleep, low mood and mood swings
- Brain fog and joint aches for some women
- Vaginal dryness, comfort and some urinary symptoms
- Bone density, lowering the risk of osteoporosis
One practical point: HRT is not a contraceptive. If you are perimenopausal you can still become pregnant, so contraception may still be needed alongside it.
The forms, and who takes what
HRT is not one thing. The form is matched to your symptoms and your risk profile with your doctor.
| Form | Best for | Notes |
|---|---|---|
| Tablets | Whole-body symptoms | Simple to take; some risks are slightly higher than skin routes |
| Patches, gels, sprays | Whole-body symptoms | Absorbed through the skin; often preferred for a lower clot risk |
| Vaginal pessaries, creams, rings | Dryness and urinary symptoms only | Act locally, with very little absorbed into the body |
The progesterone part also comes in different types, and a body-identical (micronised) form is widely used. The type, dose and route are all tailored to you rather than fixed.
Benefits and risks, honestly
For most women under 60, or within 10 years of menopause, the benefits generally outweigh the risks. Current reviews favor starting within 10 years of menopause, using transdermal estradiol at low to moderate doses (Int J Mol Sci, 2025). Much of the old fear came from a large early-2000s trial, the Women's Health Initiative. It tested only one estrogen and one progestogen combination, so its findings cannot be generalized to every hormone type or to women starting treatment around the time of menopause (Int J Mol Sci, 2025).
HRT does carry small risks that vary by the type and how you take it. Taking estrogen through the skin, as a patch or gel, avoids the small clot risk seen with tablets: transdermal estradiol is not associated with a raised clot risk, while oral estrogen is (Int J Mol Sci, 2025). That is one reason skin routes are often preferred. Breast cancer risk follows the same pattern of depending on what you take: it rises with longer use of combined estrogen-and-progestogen therapy, while estrogen-alone after a hysterectomy is neutral to favorable (Int J Mol Sci, 2025). These are small, individual considerations, not reasons for blanket fear, and your doctor weighs them against your symptoms and health. Some women, including those with certain cancers or a history of blood clots, are steered toward alternatives.
Vaginal estrogen: a special case
Vaginal dryness, discomfort and recurrent urinary symptoms are common and very treatable, and vaginal estrogen deserves its own mention. It acts locally, with very little absorbed into the body, so it is suitable for many women, including some who cannot take systemic HRT, and it can usually be continued long term. It is one of the most underused, effective options in menopause care.
HRT is not the only option
If HRT is not right for you, non-hormonal medicines, including certain prescription treatments and cognitive behavioral therapy, help with hot flashes and mood, while specific treatments ease vaginal dryness. Lifestyle measures such as strength training and bone care, steady sleep and stress management support the whole picture. Many women use a combination.
When to see a doctor
Talk to your doctor if menopause symptoms are affecting your life, or if you simply want to understand your options. A personalized conversation about the benefits and risks for you, weighing your symptoms, age and health, beats any general headline. If you have already tried HRT and it does not feel right, go back rather than stopping quietly, since the type, dose or route can often be adjusted.
Frequently asked questions
What is HRT?
Hormone replacement therapy replaces the estrogen, and usually progesterone, that falls during menopause. It is the most effective treatment for hot flashes and night sweats, helps with several other menopause symptoms, and protects bone density.
What forms does HRT come in?
Tablets, skin patches, gels and sprays, and vaginal preparations for local symptoms. Women who still have a womb usually take estrogen combined with progesterone; those who have had a hysterectomy may take estrogen alone. Your doctor tailors the type and dose to you.
Is HRT safe? What are the risks?
For most women under 60, or within 10 years of menopause, the benefits generally outweigh the risks. Older safety scares came from a trial that tested only one estrogen and progestogen combination, so its findings do not carry across to every hormone type. Small risks vary by type and route, so it is an individual decision with your doctor.
Does HRT cause weight gain?
No. HRT is not a cause of weight gain. The midlife weight shift toward the middle is driven by falling estrogen and ageing, and some women find that easing their symptoms with HRT helps them stay active. HRT is not a weight-loss treatment, but it does not add weight either.
Who might not be suitable for HRT?
Women with certain cancers, a history of blood clots, or some other conditions may be advised against systemic HRT, or offered alternatives such as vaginal estrogen or non-hormonal treatments. This is why it is always assessed individually rather than being one-size-fits-all.
