Is it too early to think about hormone therapy in my 40s?
No. HRT has the most favourable balance of benefits and risks when started before 60 or within 10 years of menopause. Who it suits, what happens at a menopause consultation, and the tests done before starting.

The short answer: No, your 40s are not too early to start the conversation. Many women begin perimenopause in their 40s, and hormone therapy (HRT) has the most favourable balance of benefits and risks when it is started before 60 or within 10 years of menopause. Whether HRT is right for you depends on your symptoms, health history and a few key tests, which is exactly what a menopause health check is for.
When is the right time to start thinking about HRT?
The best time to start thinking about hormone therapy is before you urgently need it. Perimenopause, the years of changing hormones before your final period, often begins in your 40s. You do not have to wait for your periods to stop, because HRT can be started during perimenopause if symptoms are affecting your life.
Timing also matters for safety. The Menopause Society’s 2022 position statement says that for healthy women under 60, or within 10 years of menopause, with no reasons to avoid it, the benefits of HRT generally outweigh the risks for treating symptoms and preventing bone loss. Starting much later carries more risk to the heart, brain and blood vessels. Having the conversation in your 40s keeps your options open.
What does HRT do, and who is it suitable for?
HRT replaces the estrogen your ovaries stop making. Women with a uterus also take a progestogen, which protects the womb lining. Women who have had a hysterectomy can usually take estrogen alone.
HRT can help with:
- Hot flushes and night sweats
- Poor sleep
- Mood swings and low mood linked to menopause
- Vaginal dryness and discomfort during sex
- Bone loss, lowering the risk of fractures
HRT may not be suitable if you have had:
- Breast cancer or another hormone-sensitive cancer
- A blood clot in the leg or lung, or a stroke
- Active liver disease
- Vaginal bleeding that has not been explained
The form matters too. Patches, gels and sprays go through the skin and may carry a lower risk of blood clots than tablets, which can make HRT an option for more women.
Do I need a blood test to know if I am in perimenopause?
Often not. Hormone levels rise and fall from day to day in perimenopause, so one blood test can look normal even when you have symptoms. The UK’s NICE menopause guideline advises diagnosing perimenopause in healthy women over 45 based on symptoms and irregular periods, without lab tests. For women aged 40 to 45, an FSH (follicle-stimulating hormone) blood test may be used to help confirm it.
Blood tests are still useful, though. They help rule out other causes of similar symptoms, such as thyroid problems or anaemia, and check your overall health before starting treatment.
What happens at a menopause consultation?
A menopause consultation is usually with a gynaecologist or a doctor trained in menopause care. Expect it to follow these steps:
- Your symptoms. The doctor asks about your periods, hot flushes, sleep, mood, memory, joints and sexual health.
- Your health history. Including past illnesses, surgeries, medicines and any history of cancer, clots, migraine or heart disease.
- Your family history. Especially breast or ovarian cancer, heart disease, osteoporosis and blood clots.
- A physical check. Blood pressure, weight, waist and sometimes a breast and pelvic exam.
- Tests. Your doctor orders the tests you need (see below).
- A shared decision. You talk through HRT, non-hormonal options and lifestyle changes, and choose together. If you start HRT, a review is usually booked after about 3 months.
Which tests are done before starting HRT?
Not every woman needs every test. Your doctor will choose based on your age, symptoms and risk factors.
| Test | Why it is done |
|---|---|
| Blood pressure, weight and waist | Baseline heart and clot risk |
| Mammogram (with or without breast ultrasound) | Checks breast health before starting hormones |
| Pap smear and HPV test | Routine cervical screening |
| Pelvic ultrasound | Checks the womb and ovaries if periods are very heavy or bleeding is unusual |
| FSH and estradiol | May help confirm perimenopause in women aged 40 to 45, or if the picture is unclear |
| Thyroid function (TSH) | Rules out thyroid problems that mimic menopause |
| Lipid profile, fasting glucose or HbA1c | Heart and diabetes risk |
| Liver function | Checks liver health before hormone treatment |
| Bone density scan (DEXA) | For women with risk factors for osteoporosis |
How should I prepare for my menopause health check?
A little preparation makes the consultation more useful:
- Note the dates of your last few periods
- Keep a two-week symptom diary (hot flushes, sleep, mood)
- List your medicines, supplements and any herbal remedies
- Find out your family history of breast cancer, heart disease and blood clots
- Bring past test results, especially mammograms and Pap smears
- Write down your questions, including whether you still need contraception
For blood tests that include glucose or cholesterol, you will usually be asked to fast for 8 to 12 hours.
What if HRT is not right for me?
You still have options. Non-hormonal medicines, cognitive behavioural therapy (CBT), regular exercise, strength training and good sleep habits can all ease menopause symptoms. Your doctor can help you find the right mix for your health history.
Frequently asked questions
Can I start HRT while I still have periods? Yes. HRT can be started in perimenopause if symptoms are affecting your life. Your doctor will choose a type that suits women who still have periods.
Is HRT safe in your 40s? For most healthy women, starting HRT before 60 or within 10 years of menopause has the most favourable balance of benefits and risks. A consultation checks whether it is safe for you.
Does HRT cause breast cancer? Estrogen-only HRT carries little or no extra breast cancer risk. Combined HRT slightly increases risk with longer use, and the risk falls after stopping. Your doctor will weigh this against your personal and family history.
Do I need a blood test before HRT? Not always to diagnose perimenopause, especially after 45. Blood tests are still useful to rule out other causes and check your heart, sugar and liver health.
How long can I stay on HRT? There is no fixed limit. Many women take it for several years, with a yearly review of benefits and risks with their doctor.
