You’ve probably Googled “hormone therapy” at least once. Maybe at 2am. Maybe after a hot flash that made you question your entire relationship with your own body. What you found was probably terrifying, contradictory, or both.
Here’s the thing: three-quarters of Canadian women have no idea what’s happening to their bodies during menopause… while it’s happening to them.
Only one in four reports being familiar with the signs and symptoms. So if you’ve landed here unsure whether what you’re experiencing is perimenopause, confused about hormone therapy, or wondering whether “bioidentical” is a real medical term or just something a clinic made up — you’re not behind. You’re in the majority.
In our recent Midlife Health Masterclass, Dr. Jeanne Bouteaud — OB-GYN with advanced training in Mature Women’s Health and Coral Medical Advisor1 — walked through hormone therapy without the fear and without the fluff. Here’s what she covered.
First, let’s get the language right
You may have noticed the shift from “HRT” to “MHT.” It’s not just semantics.
HRT stood for Hormone Replacement Therapy — but the term “replacement” was never accurate. The goal isn’t to replicate the natural hormonal rhythm you had before perimenopause (estrogen rising, peaking, falling, progesterone following suit). That rhythm is gone, and MHT doesn’t recreate it.
MHT — Menopausal Hormone Therapy — is more precise. It uses hormones to treat symptoms, not to restore a system that no longer exists.
And while we’re here: menopause is confirmed after 12 consecutive months without a period, in women over 45. The average age in Canada is 52. Perimenopause is the transition that leads there — it can last anywhere from two to eight years, with a symptom picture that varies enormously from one woman to the next.
What’s happening in your body
During perimenopause, your hormones stop following a predictable pattern. Instead of the regular monthly cycle of estrogen and progesterone, levels become erratic — surging one month, dropping the next, unpredictable week to week.
This is part of why hormone levels drawn on a single blood test during perimenopause can be hard to interpret in isolation. A result taken today could look completely different in six weeks. Dr. Bouteaud recommends pairing any lab work with a symptom calendar — more on that below.
“It’s really the perimenopause that’s erratic in terms of hormonal levels,” she explains. “Once you enter full menopause, stability is achieved again — at a new hormonal baseline.”
That instability is what drives most of the symptoms women experience during the transition.
The symptom list is wider than most women realize
Mood swings, brain fog, joint pain, changes in your sex drive, surprise chin hairs — yes, it’s a lot. Research has identified a significant number of symptoms associated with the menopause transition, and the full list is still being refined. The most common include:
- Hot flashes and night sweats
- Sleep disturbances
- Mood changes and increased anxiety
- Brain fog (difficulty concentrating)
- Joint pain
- Changes in sexual function (reduced libido, pain with intercourse)
- Cardiovascular and metabolic changes (including weight gain, particularly visceral fat)
- Loss of bone and muscle mass
- Changes in skin and hair
- Urogenital symptoms (bladder urgency, vaginal dryness)
What Dr. Bouteaud wants you to take away: not every woman will experience all of these, or experience them severely. This list covers what’s possible — not what’s inevitable
Your treatment options
When symptoms do appear, there’s a full spectrum of options — and they can be layered and combined.
Lifestyle changes
The evidence here is solid: reducing alcohol and tobacco use, prioritizing sleep, managing stress, and — especially — strength training all meaningfully reduce symptom burden. This isn’t optional background advice; it’s a high-return starting point at every stage, whether or not you choose any additional treatment.
“We were taught cardio, cardio, cardio,” Dr. Bouteaud says. “But weightlifting is the best type of exercise for your bone and muscle mass.” Your spin class isn’t going anywhere. But it might be time to make friends with the weight rack.
Non-hormonal options
For women who can’t or don’t want hormones, two non-pharmacological approaches have real evidence behind them:
- Cognitive Behavioral Therapy (CBT) — effective for managing symptoms and anxiety
- Acupuncture — shown to reduce hot flash frequency
A note on supplements: most over-the-counter products marketed for hot flashes have not been shown to outperform placebo. Dr. Bouteaud regularly sees patients who’ve spent months — and a lot of money — cycling through different supplements with no relief. If you’ve been down that road, it’s worth talking to a provider sooner rather than later.
A new class of non-hormonal medication
This is one of the more significant recent developments in menopause care. Fezolinetant — a new non-hormonal medication approved in Canada in 2025 — has shown:
- 50% reduction in hot flashes and night sweats by week 4
- 75% reduction by week 20
- Meaningful improvement in sleep and overall quality of life
“It’s a game changer,” Dr. Bouteaud says, “particularly for my cancer patients.”
If you were told years ago that hormones weren’t an option for you, this development is worth raising with your provider. The toolbox has genuinely grown.
Menopausal Hormone Therapy (MHT)
MHT remains the most effective treatment for hot flashes and night sweats — and its benefits go further than most women realize.
Beyond vasomotor symptoms, MHT has demonstrated effectiveness for:
- Bone protection and fracture risk reduction
- Mood support during perimenopause
- Joint pain
- Sleep disturbance
- Genitourinary symptoms (vulvar, vaginal, and bladder)
One distinction worth knowing: systemic and local treatments are not the same thing. Systemic MHT travels through the body and treats symptoms like hot flashes, mood, and sleep. Local vaginal estrogen is applied directly to treat urogenital symptoms — dryness, urgency, discomfort. Their safety profiles differ significantly. Even women who’ve had breast cancer and cannot use systemic MHT may be candidates for local treatment.
The truth about bioidentical hormones
“Bioidentical” is not a scientific term.
It emerged as a marketing term following the 2002 Women’s Health Initiative (WHI) study, designed to sound safer and more natural. The problem: it means different things depending on who’s using it.
In the United States, “bioidentical” typically refers to compounded preparations — customized hormone formulations made by compounding pharmacies. These are not currently recommended internationally because they lack safety, stability, and efficacy data.
In Canada, “bioidentical” is more often used to describe Health Canada-approved products formulated with hormones that naturally occur in the female body. These have been studied — and the data is reassuring: eight years of use with these body-identical hormones showed no increase in breast cancer risk. This is what we mean at Coral, when we use the term bioidentical. We always prescribe Health Canada-approved products.
“You really have to clarify, if you’re looking at a clinic that advertises bioidentical hormones — what is it they do?” Dr. Bouteaud says. “Are they using Health Canada products or compounding? Because one is using recommended, scientifically tested products and the other is not.”
The real risk picture
The fear around MHT traces largely to one study: the Women’s Health Initiative, published in 2002. A study that was misread, widely misreported by the media, and quietly revised over the following two decades… while the fear it created stuck around.
Here’s what it showed (and what it didn’t):
- It was designed to test whether hormones could prevent chronic disease in older women (ages 50–75), not to evaluate MHT as a treatment for menopausal symptoms
- It found a slightly increased breast cancer risk in women using combined synthetic estrogen and Provera (medroxyprogesterone acetate) for over seven years
- That risk was less than 1 additional case per 1 000 women per year after 7 years of use
- The risk was not seen in women taking estrogen alone — those women saw a reduction in long-term breast cancer risk, confirmed 22 years later
“When we simplify and say estrogen causes breast cancer, we have not seen that at all in the studies,” Dr. Bouteaud explains. “It’s really the type of progesterone being used that determines the risk — and even then, it’s extremely small, and it’s with over seven years of use.”
An honest look at the tradeoffs:
On the benefit side: symptom relief, osteoporosis prevention, fracture risk reduction, reduced insulin resistance, cardiovascular protection when started at the right time.
Worth weighing: breast tenderness and vaginal bleeding are common in the first few months (bleeding affects up to 20% of women early on). Breast cancer risk varies by hormone type and duration of use. Cost and daily commitment are real factors too. Your individual history — genetic background, breast density, personal risk factors — shapes the conversation.
When to start (and whether you’ve “missed the window”)
MHT has the greatest benefits when started within 10 years of your last period or before age 60 — particularly for cardiovascular and bone health. Starting later doesn’t close the door on treatment, but you may not get the full preventive benefits. Symptom relief, however, is available at any age.
The women who genuinely missed the window are those who were scared away from hormones by the WHI fallout 25 years ago. That fear spread widely — including among prescribers — and it caused real harm. The situation today is different.
“It’s never too early to start the conversation,” Dr. Bouteaud says, “and never too late either.”
How long do you stay on it?
Menopausal symptoms typically last 3 to 7 years. Most women use MHT for a few years — though they’re not required to stop.
There’s no age limit on continuing, and no mandatory stopping point as long as your health allows. The old guidance to stop after five years or at age 60 is no longer internationally recommended. You stop if a new medical condition creates a contraindication, or if you want to. Otherwise, the decision stays with you.
Once your dose is stable, your provider will likely want to check in around the two-year mark, then annually as you go.
What shared decision-making looks like
The thread that runned through everything Dr. Bouteaud covered: there is no single recipe for menopause care.
The right treatment depends on where you are in the transition, your symptom profile, your personal and family health history and your own preferences about medication. If you’re seeing a provider who offers only one option, dismisses your symptoms, or is still practicing based on 2002 guidance — you deserve a better conversation.
“It has to be adjusted to your health, your needs, your priorities, and your wishes,” Dr. Bouteaud says. “You can’t have one size fit all.”
A practical first step: track your symptoms
Before your next appointment, Dr. Bouteaud suggests the simplest possible tool: a printed monthly calendar.
Color-code your symptoms. Mark your cycle if you’re still having one. Track when things appear relative to your period. Four months of that pattern, brought to an appointment, gives a provider more useful information than you might expect — it shows what’s happening and when, rather than just a snapshot.
Key takeaways
- Hormone therapy is one tool in a larger toolbox — not a requirement, and not something to fear.
- MHT is the most effective treatment for hot flashes and night sweats, with additional benefits for bone, joints, cardiovascular health, and mood.
- The breast cancer risk tied to the WHI study was small, was linked to a specific hormone formulation, and emerged only after seven-plus years of use. It does not apply equally to all forms of MHT.
- “Bioidentical” is a marketing term with no scientific definition. It’s important to clarify what it means with each clinic/provider when they use this term for the products they prescribe.
- Fezolinetant, approved in Canada in 2025, is a highly effective non-hormonal option for women who can’t or don’t want hormones.
- Starting within the window (within 10 years of your last period or before 60) offers the most benefit — but the conversation is worth having at any stage.
- Your symptoms are real. Your options are broader than you may know.
