What is the average age for HRT?

There's no single "right" age for starting HRT. What matters most is whether your symptoms are affecting your quality of life.

Can you start HRT after your periods have stopped?

Yes. HRT can be started at any point after menopause, though the evidence for long-term benefits (particularly for the heart) is strongest when begun within 10 years of your last period. If it's been longer, a clinician can help you weigh up the options for your individual circumstances.

When do HRT patches start to work?

Most women begin to notice an improvement in symptoms within a few weeks, though the full effect can take up to three months. If you still think your HRT isn’t working after three months, it’s worth revisiting your treatment plan with your doctor. Sometimes the dose or type you’re taking just needs a tweak.

When to start HRT after a hysterectomy?

If you've had a hysterectomy, you can take oestrogen-only HRT. This can be started as soon as you experience menopausal symptoms, including if surgical menopause occurs before natural menopause age. Early treatment is particularly important after surgical menopause, as the hormonal drop is abrupt rather than gradual.

When is it too late to start HRT?

For managing symptoms, HRT can help at any age. For long-term protective benefits (bone and cardiovascular health), the evidence is strongest when started within 10 years of the last period or before age 60.

What to expect when you start HRT?

The first few weeks can involve some adjustment, and symptoms such as mild breast tenderness, bloating or spotting aren't unusual as your body adapts. These usually settle. Regular check-ins with your clinician make a real difference.

How does a woman know if she needs hormone replacement?

There's no definitive test to know if you need HRT. It comes down to symptoms and how they're affecting your life. If you're experiencing hot flushes, sleep problems, mood changes, brain fog or other symptoms listed above, it's worth having a conversation with a clinician who specialises in menopause.

What are the signs of low oestrogen levels?

Low oestrogen typically shows up as hot flushes, night sweats, vaginal dryness, irregular or absent periods, low mood, poor sleep, and reduced bone density over time. Many of these overlap with general perimenopause and menopause symptoms. Some low oestrogen symptoms are more surprising, such as itchy ears, restless legs and acid reflux.

Is it better to go through menopause without HRT?

For some women—particularly those with a history of certain hormone-sensitive cancers—HRT may not be appropriate, and alternatives can help. But for the majority of healthy women, the evidence does not support the idea that it's better to go without. Untreated menopause symptoms can significantly affect quality of life, relationships, and work. The decision should always be made with good information and a clinician you trust.

Will I age quicker without HRT?

Oestrogen plays a role in skin collagen, bone density, and cardiovascular health, so its decline does have physical effects. Some research suggests HRT may help preserve skin thickness and reduce fracture risk. That said, "ageing quicker" is a complex question and lifestyle factors like diet, sleep, exercise, and not smoking also have a major influence.

If you've found yourself Googling "Am I in perimenopause?" at 3 am after waking in a cold sweat, you're not alone. Millions of women are navigating hormonal changes right now, often without the information they need to make sense of what's happening to their bodies.

Hormone replacement therapy (HRT) replaces the hormones that your body produces less of as you approach and move through menopause. For many women, the relief HRT brings is transformative. Yet a lot of us delay seeking help.

Here are the signs your hormones may be behind how you're feeling.

What are the signs that you might need hormone replacement therapy?

Hormonal changes don't usually announce themselves with a single, obvious menopause symptom. For many women, the signs creep in gradually, before the picture becomes clearer. If several of the following feel familiar, it may be worth exploring with your GP or specialist menopause clinician whether HRT could help.

Night sweats and hot flushes

These are the symptoms most associated with menopause, and for good reason. Fluctuating hormone levels disrupt the body's temperature regulation, triggering sudden waves of heat, flushing, and night sweats.

Sleep disruption

Poor sleep often goes hand in hand with night sweats, but hormonal changes can also independently affect sleep quality. If your sleep has changed lately, perhaps you’re waking frequently, struggling to nod off, or feeling exhausted despite a full night in bed, hormones may be playing a role.

Low mood, anxiety and irritability

Oestrogen can impact your mood. As levels fluctuate, many women experience heightened anxiety, low mood, or a shorter fuse than usual.

Brain fog and memory lapses

Forgetting words mid-sentence, struggling to concentrate, and feeling mentally slower than usual are widely reported during perimenopause and menopause. While they can feel alarming, many women find them significantly improved with HRT.

Vaginal dryness and discomfort during sex

Lower oestrogen thins the vaginal tissues, leading to dryness, irritation and discomfort during sex.

Joint aches and reduced libido

Oestrogen has an anti-inflammatory role, so its decline can leave joints feeling stiff or achy. Meanwhile, falling testosterone (yes, women have it too) commonly reduces sex drive. If you've noticed a drop in desire that feels out of character, it's worth mentioning to your doctor.

When should you start HRT?

There's no universal answer about when’s best to start HRT, but the evidence increasingly supports starting sooner rather than later—particularly for protecting long-term bone and cardiovascular health.

The most important thing? Don't wait until symptoms become unbearable. If they're affecting your quality of life, that's reason enough to seek help.

When to start HRT: perimenopause vs menopause

Knowing the difference between perimenopause and menopause can help you make a more informed decision about when to start HRT.

When to start HRT in perimenopause

Perimenopause, the transitional phase leading up to your final period, can last several years. Hormone levels fluctuate unpredictably during this time, which is what causes so many symptoms. You don't need to wait for your periods to stop before considering HRT.

Starting HRT in perimenopause can smooth out those hormonal peaks and troughs, reducing symptoms.

When to start HRT after menopause

That said, you can absolutely start HRT after your periods have stopped. Menopause is confirmed after 12 consecutive months without a period if you’re over 50, but this doesn't close the door on HRT. Many women begin treatment years into menopause.

Benefits and risks of HRT

HRT has come a long way from the scary headlines in the early 2000s. The benefits of hormone HRT usually outweigh the risks. The risks of serious side effects from HRT are very low.

The most discussed is a small increase in breast cancer risk associated with combined HRT (oestrogen plus progesterone). However, factors such as drinking alcohol, leading a sedentary lifestyle and being overweight all increase the risk of breast cancer more than HRT.

The benefits and risks of taking HRT depend on your age, your menopause symptoms and any risk factors you have. Your doctor will take all these factors into account and help you find the right menopause treatment plan.
