Perimenopause: the symptoms that start while your periods still come
Source: SOGC, Menopause and U; Ontario Health, Menopause quality standard.
Perimenopause is the stretch before your last period, when hormone levels rise and fall unpredictably. Perimenopause symptoms often start in your 40s, while your periods still come: night sweats, waking at 3am, brain fog, mood changes, anxiety, periods that change. For most people, symptoms are enough to identify it. Hormone therapy and non-hormonal options can help.
What perimenopause sounds like, in your words.
Many symptoms or none, mild or severe, changing over time. Most don't sound like hormones at all.

"I wake up soaked."
Night sweats are hot flashes at night: heat that starts in the chest and rises, usually for 3 to 4 minutes, sometimes with anxiety or a pounding heart.

"I'm wide awake at 3am."
Trouble sleeping is a common perimenopause symptom. Night sweats are an important cause of broken sleep, so the two often travel together.

"I lose words mid-sentence."
Problems with concentration or memory, often called brain fog. Losing the word, losing the thread, losing why you walked into the room.
"I snap, or cry, or feel anxious, and don't know why."
Low mood and anxiety are listed perimenopause symptoms, not a character flaw.
"My periods have gone unpredictable."
Closer together, further apart, heavier, lighter or skipped. A cycle that keeps shifting by 7 days or more is one of the markers clinicians use for perimenopause.

"My joints ache when I get up."
Aches and pains in the joints or muscles are on the list too. So are vaginal dryness, needing to pee urgently, a lower sex drive and changes in weight or shape. Dryness and bladder changes tend to continue or get worse unless treated, so say them out loud.

That's the short version. Your list has all 17, in plain words, on one page.
Perimenopause usually starts years before your last period.
Menopause itself is one day: 12 months after your last period. The average age is about 51; about 90% reach it between 45 and 55. Perimenopause comes first. On average it begins 4 years before the last period, but it can start up to 10 years before, and it can last up to 10 years.

So symptoms in your early 40s are not "too young". That's why Ontario's menopause quality standard asks clinicians to ask about menopause symptoms from age 40. If nobody asked you, we will.

If your periods stop before 40, that needs a clinician's look to find out why. It may not be perimenopause at all.

"Your labs are normal."
For most people, symptoms are enough to identify perimenopause or menopause. Blood tests or imaging are not needed. In perimenopause, hormone levels go up and down.

What helps: hormone therapy where it fits, and a plan B where it doesn't.
Hot flashes and night sweats
You don't have to wait for menopause to be treated. Ontario's standard says hot flashes and night sweats in perimenopause or menopause should be offered menopausal hormone therapy as first-line treatment, after your risks and preferences are assessed. Canada's obstetrician-gynaecologist society (SOGC) calls hormone therapy the most effective treatment for troubling menopause symptoms.

The standard describes it as a first-line option for people younger than 60, or less than 10 years past menopause. Your history comes first, and nothing is prescribed on a form.

If hormones aren't for you
There's a plan B. Non-hormonal prescription options can treat hot flashes and night sweats, and cognitive behavioural therapy is an evidence-based option too. If hormone therapy isn't right for you, we'll tell you, and tell you why.

Sleep, mood and brain fog
If night sweats are what wake you, treating them may help your sleep. Low mood and anxiety have their own options, including cognitive behavioural therapy. Straight answer on brain fog: hormone therapy hasn't been shown to improve memory and thinking scores over years of use. We'll still go through it, and what's feeding it.

One more thing
You can still get pregnant during perimenopause. Birth control is part of the conversation.

When to book.
- Your symptoms are getting in the way of sleep, work or home. Whether a symptom is bothersome is entirely up to you.
- You're 40 or over and nobody has asked about menopause symptoms.
- You want to know if hormone therapy is an option, or what the options are if it isn't.

Assessment online, from home, with a Nurse Practitioner, wherever you are in Ontario. Bloodwork only if it will change a decision, at a lab near you. Follow-ups from home too. You can book with us directly; if you do have a family doctor, we can send them a summary, with your permission.
Some things don't wait for a list. Very heavy bleeding, or bleeding between periods or after sex: speak to a clinician. Bleeding after menopause, or a new breast lump: contact a clinician promptly or call Health811 (811). Chest pain, sudden weakness or stroke signs: call 911.

Asked plainly
Answered plainly.
01Is 46 too early for menopause?
No. About 90% of people reach menopause between 45 and 55, and perimenopause starts years before that. Menopause between 40 and 44 is called early menopause, and before 40 it needs a clinician's look.
Source: Ontario Health, Menopause quality standard.
02Can I take HRT during perimenopause?
It can be offered in perimenopause for hot flashes and night sweats, after your own risks are assessed. Your history decides, not the calendar.
03How long do perimenopause symptoms last?
Perimenopause can last up to 10 years. Hot flashes and night sweats last a median of 7 years after the last period.
