You're not sleeping well. Your mood feels unpredictable. You're gaining weight around your middle despite nothing changing in your diet. Brain fog is making it hard to concentrate at work. You're in your early to mid-40s and wondering if something is wrong.
There's a good chance you're experiencing perimenopause symptoms, and you're far from alone. This transitional stage before menopause can last anywhere from two to twelve years, yet most people have never heard of it when it starts. At NuHaven Health in Saint John, we hear this story constantly: patients who spent months or years confused by their own bodies before someone finally named what was happening.
This post is that conversation.
What Is Perimenopause, and When Does It Start?
Perimenopause is the hormonal transition phase leading up to menopause, when the ovaries gradually begin producing less estrogen and progesterone. Menopause itself is defined as 12 consecutive months without a period. Everything before that point is perimenopause.
So what age does perimenopause start? Most people begin the transition in their mid-40s, though early perimenopause symptoms can appear as young as 35 to 38 in some cases. The timing is largely genetic, so if your parent went through menopause early, you may too. There's no single trigger and no precise schedule. That unpredictability is part of what makes it so disorienting.
The hormonal fluctuations during this phase are real, significant, and often more chaotic than what people experience during menopause itself. Estrogen doesn't decline in a straight line, it swings up and down before eventually falling, which is why symptoms can feel inconsistent and hard to pin down.
Common Perimenopause Symptoms
If you've gone looking for a list of perimenopause symptoms, you may have come across references to 34 or even more distinct signs. While the exact count varies depending on the source, the breadth of the list reflects something important: perimenopause affects nearly every system in the body, not just the reproductive one.
Here are the most commonly reported symptoms:
Sleep and energy
- Waking frequently through the night
- Difficulty falling asleep or staying asleep
- Fatigue that sleep doesn't resolve
Mood and cognition
- Increased anxiety or a sense of low-grade dread
- Mood swings that feel disproportionate to the situation
- Brain fog, memory lapses, difficulty concentrating
- Decreased motivation or sense of flatness
Physical changes
- Hot flashes and night sweats (vasomotor symptoms)
- Irregular or heavier periods
- Weight gain, particularly around the abdomen
- Joint aches and muscle tenderness
- Heart palpitations
- Changes in skin, hair, and libido
Vaginal and urinary symptoms
- Vaginal dryness or discomfort
- Increased urinary urgency or frequency
- Recurrent urinary tract infections
It's worth noting that menopause anxiety is one of the most underrecognized symptoms on this list. Many people are treated for anxiety disorders during perimenopause without anyone connecting it to hormonal changes. If your anxiety appeared or significantly worsened in your late 30s or 40s, it's worth exploring the hormonal connection.
What's Normal and What Deserves Attention
Some variability in this stage is expected. Irregular periods, occasional hot flashes, and mild sleep disruption are common and manageable. What isn't something to simply push through:
- Periods that are extremely heavy, very close together, or lasting longer than 7 days
- Mood changes so significant they're affecting relationships or work
- Anxiety, depression, or cognitive symptoms that feel new or out of character
- Symptoms that are disrupting your quality of life on a regular basis
The most important thing to understand is that perimenopause symptoms are not a moral test. They are a physiological event driven by hormonal shifts, and there are effective evidence-based treatments, including hormone replacement therapy (HRT) and non-hormonal options, that can make a significant difference.
The Menopause Society is clear that HRT is safe and appropriate for most healthy perimenopausal and menopausal patients, particularly those under 60 or within 10 years of their last period. The outdated fear around HRT has held too many people back from treatment that could genuinely help.
Why Getting the Right Diagnosis Matters
One of the challenges with perimenopause is that its symptoms overlap with so many other conditions: thyroid disorders, depression, anxiety, iron deficiency, and sleep disorders, among others. A thorough assessment matters.
At NuHaven Health, our approach starts with listening. We review your symptom history, cycle patterns, and overall health before recommending anything. Our clinical team is led by Angela McGraw, DNP, NP, MSCP, one of a select group of Menopause Society Certified Practitioners in Canada. That credential, the recognized gold standard in menopause medicine, shapes how we assess and treat every patient who comes through our door.
Whether you're just beginning to notice changes or have been struggling with symptoms for years, a proper evaluation can give you clarity and a path forward. Explore our women's hormone health services to learn more about what assessment and treatment looks like at NuHaven.
Menopause Weight Gain: A Note on One of the Most Frustrating Symptoms
We'd be doing our patients a disservice to not address this directly. Menopause weight gain, particularly the accumulation of fat around the abdomen, is one of the most distressing changes for many people going through perimenopause, and it's one of the most misunderstood.
This shift isn't simply about eating more or moving less. Declining estrogen changes how the body distributes and stores fat. Insulin sensitivity can shift. Sleep disruption affects hunger hormones. These are metabolic changes, not failures of willpower.
Treatment approaches that combine clinical hormone management with lifestyle support, including sustainable movement strategies, nutrition guidance, and metabolic health coaching, tend to produce the best outcomes. At NuHaven, our team includes both clinical and coaching support to address this from both directions.
