If you are approaching or going through menopause, you may have heard HRT suggested for symptom relief. So what is HRT? Hormone replacement therapy (HRT) is a treatment that replaces hormones — mainly estrogen — that fall to low levels during menopause, easing symptoms like hot flashes, night sweats, and vaginal dryness.
How HRT works
As you move through perimenopause and into menopause, your ovaries gradually produce less estrogen and progesterone. That hormonal shift drives many of the symptoms people notice. HRT works by topping up the hormones your body is no longer making in the same amounts, which helps steady levels and relieve symptoms.
Most people find that once hormone levels rise again, troublesome symptoms ease considerably. To understand where this fits in the wider transition, see our guides on perimenopause symptoms and what is menopause.
The main types of HRT
There are two broad approaches, and which one suits you depends largely on whether you still have a uterus.
- Estrogen-only HRT — usually prescribed for people who have had a hysterectomy (no uterus).
- Combined HRT (estrogen plus a progestogen) — for people who still have a uterus. The progestogen protects the lining of the uterus, lowering the risk of cancer that estrogen alone can cause.
HRT also comes in several delivery methods, so treatment can be tailored to your preferences and health needs:
- Tablets
- Skin patches
- Gels and sprays
- Vaginal creams, tablets, pessaries, or rings (often used for localized symptoms such as dryness)
What symptoms can HRT help with?
HRT is considered one of the most effective treatments for the core symptoms of menopause. According to health authorities, it can help relieve:
- Hot flashes and night sweats
- Sleep disruption
- Mood changes, anxiety, and low mood
- Vaginal dryness and related discomfort
It can also help prevent osteoporosis, the weakening of bones that becomes more common after menopause. For symptom-specific guidance, see hot flashes: causes and relief, menopause and sleep problems, and menopause and mood changes.
Benefits and risks to weigh
Like any medicine, HRT has both benefits and potential risks, and these vary from person to person.
Possible benefits
- Effective relief of hot flashes, night sweats, and vaginal dryness
- Better sleep and mood for many people
- Reduced risk of osteoporosis and related fractures
- Some forms of combined therapy may lower colon cancer risk
Possible risks
- A small increase in breast cancer risk with some types, especially with longer use
- A higher risk of blood clots or stroke with certain forms
- Greater cardiovascular risk if HRT is started many years after menopause begins
Your age, family medical history, personal health history, and symptom severity all shape the balance of benefits and risks. For most people who begin HRT near the start of menopause, the benefits are generally considered to outweigh the risks — but this is an individual judgment, not a blanket rule.
Who may need to be cautious
HRT is not suitable for everyone. People with a history of certain cancers, blood clots, uncontrolled high blood pressure, or liver disease may need alternatives. A range of non-hormonal options exists too, including lifestyle changes and prescription medicines for specific symptoms.
How HRT is started and reviewed
If you and your provider decide HRT is appropriate, treatment often begins at a lower dose, which may be adjusted over time. A follow-up appointment — often around three months after starting — is common, to check how well it is working and whether any changes are needed.
There is no single "correct" length of time to stay on HRT. Some people use it for a few years; others continue longer. The right duration is reviewed regularly with your provider based on your symptoms and risk profile. To see how the broader transition unfolds, compare perimenopause vs. menopause.
The bottom line
HRT replaces the estrogen — and often progestogen — that decline during menopause, and it remains one of the most effective ways to relieve hot flashes, night sweats, sleep problems, and vaginal dryness. It can also protect bone health. The benefits and risks depend on your age, health history, and the type and timing of treatment, so HRT is a personal decision best made together with your healthcare provider.
