Perimenopause Symptoms: What's Actually Happening to Your Body (And What to Do About It)

 If you've been feeling off lately — not sleeping well, snapping at people you love, skipping periods or having them more often than you'd like — you might be wondering if this is just stress, or something more.

For a lot of women in their late 30s and 40s, the answer is perimenopause. And the frustrating part? Most of us were never told it was coming.

Let's change that.

What Is Perimenopause, Exactly?

Perimenopause is the transition phase before menopause — and it can last anywhere from 2 to 10 years. It starts when your ovaries begin producing less estrogen, and it ends 12 months after your last period (that's when you officially reach menopause).

The average age it starts is around 47, but it's not uncommon to see signs in your late 30s. And because the symptoms can look like so many other things — burnout, thyroid issues, anxiety, depression — it often goes unrecognized for years.

The Most Common Perimenopause Symptoms

Every woman experiences this transition differently, but here are the symptoms I hear about most often in my practice:

Changes to your cycle
Your period might become irregular — longer, shorter, heavier, lighter, or just unpredictable. This is usually one of the first signs.

Hot flashes and night sweats
Sudden waves of heat, sometimes followed by chills. At night, these can wake you up repeatedly, leaving you exhausted by morning.

Sleep problems
Difficulty falling asleep, waking up at 3am with your mind racing, or just never feeling rested. This one affects quality of life enormously.

Mood changes
Increased anxiety, irritability, low mood, or feeling emotionally reactive in ways that don't feel like "you." This is real — it's driven by hormonal fluctuations, not just stress.

Brain fog
Forgetting words mid-sentence. Walking into a room and not remembering why. Struggling to concentrate. Estrogen plays a role in cognitive function, so as levels shift, so can mental clarity.

Vaginal dryness and discomfort
Declining estrogen affects vaginal tissue, leading to dryness, discomfort during sex, or more frequent UTIs. This is one of the most underreported symptoms because women often feel embarrassed to bring it up — please don't be.

Weight changes
Many women notice weight redistributing around the midsection during perimenopause, even without changes to diet or exercise. Hormonal shifts affect how your body stores fat.

"Is This Just Normal Aging?"

I get asked this a lot. And the honest answer is: some change is normal, but suffering through it isn't your only option.

There's a difference between experiencing a natural transition and having your quality of life significantly disrupted. If symptoms are affecting your sleep, your relationships, your work, or your mental health — that's worth addressing.

What Can Actually Help

The good news is that there are evidence-based options that make a real difference. Depending on your symptoms and health history, that might include:

  • Hormone therapy (HRT) — more on this in a future post, but the research on this has shifted significantly in the last decade and it's far safer for most women than old headlines suggested
  • Non-hormonal medications for specific symptoms like hot flashes or mood changes
  • Lifestyle strategies — sleep hygiene, stress management, nutrition, and exercise all play a meaningful role
  • Targeted supplements — some have solid evidence behind them, many don't, and sorting through the noise is part of what I do

When to See Someone

You don't have to wait until things get bad. If you're noticing changes and wondering if perimenopause might be the reason — that's already a good enough reason to book an appointment.

From Registered Nurse to Family Nurse Practitioner: A Personal Journey to Primary Care in Edmonton, Alberta

 People sometimes ask me when I knew I'd become a Nurse Practitioner. The honest answer is that I didn't know — not for a long time. My name is Kari Scinski, and I'm a new Nurse Practitioner working in primary care in Edmonton, Alberta. My path here wasn't a straight line. It was a slow accumulation of moments at the bedside that, eventually, made the next step feel inevitable. Why I Chose Nursing in the First Place Long before I was thinking about Nurse Practitioner programs in Alberta, I was a Registered Nurse trying to understand what good care actually looked like. The textbook answers were one thing. The hallway answers — the ones you only learn by being present with patients and families — were another. Nursing rewards anyone willing to slow down, ask the next question, and stay in a difficult conversation a few seconds longer than feels comfortable. That's the part of the work I fell in love with, and that's the part I refuse to leave behind as my scope...

Seeing the Barriers Up Close: What Underserved Care Taught Me as a New NP in Edmonton

Seeing the Barriers Up Close Beginning work with an underserved population can be shocking — not because the challenges are unknown, but because of how constant and layered they are. It quickly becomes clear that illness is often only one part of the story. Many patients are not just managing depression, anxiety, chronic pain, diabetes, addiction, disability, or trauma. They are also trying to survive unstable housing, poverty, food insecurity, limited transportation, gaps in medication coverage, and systems that are difficult to understand even for those of us working within health care. As a health care provider, it can be jarring to realize how much of the work extends beyond diagnosis and treatment. A patient may need a prescription, but first they need coverage. They may need counselling, but first they need transportation. They may need rest and stability, but first they need housing. They may qualify for AISH, Income Support, OAS, or other supports, but the process of applying c...
