Before we start
If you’ve made it here, you’re probably in that stage where your body does strange things and nobody gave you the manual.
The hot flashes that wake you at three in the morning, sleep that isn’t what it used to be, that little voice asking “is this normal?”.
Menopausal hormone therapy (HRT) is one of the most effective and worst explained tools of this stage.
Here’s the whole story: what really helps, what to watch out for and the mess of misinformation around it. No scare tactics, nothing to sell you.
In this guide
Everything you
need to know
Start by recognising it
7 clear signs you’re
low on oestrogen
- 01
You wake up at 4 in the morning
And can’t get back to sleep. It’s a pattern: every night, at the same time, eyes open and your mind racing.
- 02
Extreme dryness
In your vagina, your skin, your eyes.
- 03
Mood swings that don’t feel like you
Out of nowhere you feel rage. Anxiety that appears for no reason. Emotional outbursts you’ve never had before. And afterwards you wonder what happened.
- 04
Your body aches for no reason
Your hands, your back, the soles of your feet, even frozen shoulder. Oestrogen is anti-inflammatory: when it drops, the body becomes inflamed and pain appears.
- 05
Urinary infections, one after another
Sometimes with antibiotics that never quite clear them. Without oestrogen, vaginal pH changes and lactobacilli decrease: the good bacteria that protect the area.
- 06
You forget words
You’re talking and the word disappears. You know it, but it won’t come.
- 07The hardest to explain
You feel like you’re not you anymore
It’s not a single symptom. It’s everything combined: poor sleep, pain, mood changes, brain fog. Together they make you look in the mirror and not recognise yourself. You feel you’ve lost something but can’t say exactly what.
If you recognise any of these signs, you’re in the right place.
Why it happens
Oestrogen doesn’t only act on the reproductive system
Oestrogen is one of the key pieces behind menopause symptoms.
- Stable
- Fluctuates
- Drops
When it fluctuates and drops, you get:
- hot flashes
- insomnia
- joint pain
- vaginal dryness
- fatigue
- brain fog
That’s why, when properly indicated, hormone therapy can relieve many of these symptoms and greatly improve quality of life.
First, the basics · in 30 seconds
What HRT is
HRT replaces some of the hormones your ovaries stop making:
- Oestrogen
- mainly
- Progestogen
- almost always · progesterone or similar
- Testosterone
- sometimes, a little
It’s not “a pill”: it comes as
- patches
- gels
- sprays
- tablets
- vaginal creams
and how you take it matters as much as the dose.
Menopause isn’t an illness or something that needs “fixing”; but if symptoms are making life hard, you have options.
Has anyone explained the hormones?
The hormones in HRT
- 01Oestrogen
Estradiol
Chemically identical to the oestrogen your ovaries produce. It improves hot flashes and sleep, eases joint pain and gives you that feeling of having your body and brain back.
- 02Oestrogen
Conjugated oestrogens
They also help with hot flashes, insomnia and pain. They are mixtures of several oestrogen molecules of equine origin.
- 03Progestogen
Progesterone
It’s not an oestrogen: it goes with it. If you have a uterus and are prescribed systemic oestrogen, you almost always need progesterone to protect the endometrium. It also reduces hot flashes, improves sleep and can help stabilise temperature swings and anxiety.
Both are approved; the choice depends on your case.
Not all oestrogen is used the same way
Local vs. systemic
Local
Vagina · vulva · urinary tract
Applied directly to the area that suffers most from the hormonal drop.
Helps with
- dryness
- burning
- pain during sex
- urgency to urinate
- recurring urinary infections
Comes as
vaginal creams, pessaries or rings
Systemic
Whole body
Absorbed and circulated throughout the body. For symptoms beyond the vaginal area.
Helps with
- hot flashes
- sleep problems
- joint pain
- brain fog
Comes as
patches, gels, sprays or pills
Two different routes. For different symptoms. And sometimes they’re combined.
Low-dose vaginal oestrogen generally doesn’t need a progestogen.
If you have urine leakage, talk to your doctor: depending on the type, local oestrogen may or may not be part of the treatment.
The good
Where it works best
The best there is for hot flashes and night sweats
+80%
of women get relief with low to moderate doses. Nothing beats it, and you often notice the improvement within a couple of weeks.
Both transdermal and oral routes are effective. This use has the strongest evidence.
Related alternatives: tibolone (STEAR; effective but less so than standard HRT), estetrol (E4) 15 mg, and the TSEC complex (conjugated oestrogens + bazedoxifene).
Your bones will thank you
First-line treatment to prevent menopausal bone loss; it reduces fracture risk, with a better balance if started within 10 years / before 60. Note: stopping it leads to rapid bone loss.
It lowers the risk of the leading cause of death in women
In women under 60, recently menopausal and without cardiovascular disease, oestrogen therapy reduces coronary heart disease and all-cause mortality. It also reduces new-onset diabetes.
Backed by Cochrane, meta-analyses and the 18-year WHI follow-up.
Restores intimate health
Vaginal oestrogen is recommended for genitourinary syndrome of menopause (GSM). The evidence is strong. It works very well for dryness, discomfort during sex or recurring urinary infections, and no systemic risks have been identified at low doses. It can be added if GSM persists despite systemic HRT.
Alternatives: intravaginal DHEA (prasterone) and ospemifene.
Duration
There are no mandatory limits. Whether to continue is an individual decision between an informed woman and her clinician.
The window of opportunity
If you start early (before 60 or within 10 years of your last period), the balance works in your favour.
In healthy women in this group, oestrogen is linked to less heart disease, lower mortality and even a lower risk of diabetes.
Early menopause?
If it came before 40 (premature ovarian insufficiency) or between 40 and 45, HRT isn’t just for symptoms: it’s long-term protection for your bones, heart and brain.
It’s recommended to start as soon as possible and continue at least until the usual age of menopause.
If this is you, it’s a priority conversation with your doctor.
What to keep in mind
No drama, no downplaying
It isn’t for everyone. There are situations where it’s not appropriate, especially with systemic oestrogen:
- unexplained bleeding
- hormone-dependent cancers
- active blood clots
- acute liver disease
- uncontrolled high blood pressure
For women with a history of breast cancer, local oestrogen is a separate assessment, together with oncology.
That’s why it’s a conversation, not self-service.
Blood clots and the oral route
- Pill
- raises the risk of thrombosis
- Patch or gel
- doesn’t raise it
Not even if you have risk factors. That’s why treatment often starts there. When there’s risk, micronised progesterone, dydrogesterone or an LNG-IUD are preferred.
Timing matters (again)
Stroke risk depends on when you start.
- Before 60 / within 10 years
- risk similar to not using it
- Started later
- oral HRT is linked to higher risk
- Transdermal and low dose
- lower risk
Breast cancer, calmly
The risk attributable to HRT is small, similar to or lower than inactivity, obesity or alcohol.
- Combined HRT increases risk with duration, and it falls after stopping.
- The increase is mainly linked to synthetic progestogens (e.g. CEE+MPA); it appears lower with micronised progesterone or dydrogesterone.
- HRT (and tibolone) is not recommended with breast cancer or high risk.
- Vaginal oestrogen does not suggest higher risk in women without a history.
If you have a uterus, progestogen isn’t optional
Oestrogen alone can thicken the lining of the uterus; progestogen protects it. Non-negotiable, but very easy to sort out.
Continuous combined therapy carries a lower risk of endometrial cancer than not using HRT. Switching from sequential to continuous is suggested after 5 years or at age 54.
What the evidence says today
Testosterone
Testosterone isn’t a cure-all
Its only evidence-based indication is postmenopausal hypoactive sexual desire disorder (HSDD). For now it isn’t supported for other symptoms or prevention.
DHEA
Systemic DHEA
Not backed by strong evidence. Intravaginal DHEA (prasterone) is effective for pain during sex caused by atrophy.
New studies could change this, but today this is the best evidence.
Worth remembering
Your age and the years since your last period matter too.
The benefits and risks are not the same if you start close to menopause as many years later.
The hard part
The historic scare, the information gap and the snake oil
The big scare
2002
A huge study (the WHI) came out with alarming headlines and, overnight, half the world stopped HRT.
It mainly studied older women, long past menopause, and the risks were communicated as if they applied to everyone equally.
A generation of women putting up with symptoms out of fear of a treatment that, for many, was safe.
Twenty years later, regulators (the FDA in 2025-26) have removed the most severe warnings, recognising they had been applied with far too broad a brush.
“Why did nobody tell me?”
That information gap is real, and it’s exactly why spaces like this exist. You’re not exaggerating: for years the system downplayed all of this.
Not recommended
Compounded bioidentical hormones
Guidelines do not recommend them due to a lack of quality control, regulatory oversight and evidence of safety, purity and efficacy. Regulated HRT is advised.
We know not every therapy is accessible or available in every market, and that shortages are used by pharma companies to raise prices. But the lack of control over bioidenticals is real.
The noise online
There’s a huge amount of information about menopause out there, and much of it is marketing dressed up as advice.
Simple rule: if something sounds like a miracle cure, it probably is.
What to take to your appointment
You don’t need the decision made. You need good questions.
- 1Given my age, stage and history, am I a good candidate?
- 2Which of my symptoms would it really help… and which not?
- 3Is a patch/gel or a pill better for me, and why?
- 4Do I need a progestogen? Which one?
- 5What specific risks apply to me, in real numbers and not just percentages?
- 6If my symptoms are mainly vaginal or urinary, can vaginal oestrogen help even if I take nothing systemic?
- 7How often do we review it?
What information to bring
- 01
Your menstrual history
The date of your last period, how your cycles have changed, and whether you’ve had a hysterectomy or your ovaries removed. It defines the “window” and whether you need a progestogen.
- 02
Your symptoms, tracked
How many a day, whether they wake you, how much they interfere (1 to 10), since when and what you’ve tried. One or two weeks of tracking is worth more than memory.
- 03
Your medical history
Blood clots or thrombosis, heart problems, high blood pressure, migraines (and whether with aura), liver or gallbladder disease, and any cancer you’ve had.
- 04
Your family history
Especially breast or ovarian cancer, and early thrombosis or heart attacks in close relatives. It helps estimate your baseline risk.
- 05
Medication and supplements
The full list, including contraceptives and any “natural” hormones you’re taking.
- 06
Recent health data
Blood pressure, weight/BMI, and the date of your last mammogram and Pap test. If you have a bone density scan (DXA) or lab results, bring them.

In summary
HRT is one of the most effective therapies for menopause symptoms, and the fear around it was, for most women, overblown.
It’s a nuanced decision: your age, your stage, the route and your history. Understanding the map is enough to ask good questions. That’s what this guide is for.
Don’t self-medicate. Look for menopause specialists who can assess your case and prescribe the best option for you.
