Perimenopause, the years leading up to your last period, can start affecting your heart long before menopause itself begins. Palpitations, rising blood pressure, and cholesterol changes are common during this transition, and most are benign, but some are worth a closer look.
Most conversations about menopause and heart health focus on the period after your last menstrual cycle. But perimenopause (which can last anywhere from a few years to a decade) is often when the first cardiovascular changes actually begin, quietly, while periods are still happening.
If you're in your late 30s to late 40s and noticing new palpitations, mood changes, disrupted sleep, or a first "borderline" blood pressure or cholesterol reading, this stage (not menopause itself) may already be the cause.
Many of the women I see for this feel caught in between. They're too young, in their own minds, to be thinking about "menopause," but something has clearly shifted. Their periods are less predictable, their sleep is worse, and they're noticing their heart in a way they never used to. That in-between feeling is exactly what perimenopause is, and it deserves its own conversation rather than being folded into menopause advice that doesn't quite fit yet.
Noticing changes but not sure if it's perimenopause or something else?
Perimenopause and Your Heart: What's Actually Happening
Perimenopause is the transitional stage before menopause, when the ovaries gradually produce less estrogen. It typically begins in the mid-to-late 30s or 40s and can last anywhere from a few years to over a decade before periods stop completely. Unlike menopause (a single point in time defined as 12 months without a period) perimenopause is a moving target, and its length and intensity vary enormously between women.
What makes perimenopause distinct, physiologically, is that estrogen doesn't decline in a smooth, predictable line. It fluctuates, sometimes swinging higher than usual before eventually trending down. This hormonal instability, rather than a simple gradual decline, is part of why perimenopause can feel more unpredictable and unsettling than menopause itself, both emotionally and physically.
What Actually Changes During Perimenopause
Palpitations — often the first cardiovascular symptom women notice, usually benign but understandably alarming
Blood pressure fluctuations — some women see their first elevated readings during this stage, years before actual menopause
Cholesterol shifts — LDL can begin rising even while periods are still regular
Sleep disruption — independently linked to worse cardiovascular markers, not just daytime fatigue
Anxiety and mood changes — can overlap with, and sometimes mask, genuine cardiac symptoms like breathlessness or chest tightness
Weight redistribution — many women notice fat shifting toward the abdomen during perimenopause even without significant weight gain, which independently affects cardiovascular risk.
Perimenopause vs. Menopause — Why the Distinction Matters
Menopause is a single point in time — 12 months without a period.
Perimenopause is the unpredictable stretch of years beforehand, and it's arguably more relevant for early heart health screening, precisely because most women (and many doctors) don't think to look for cardiovascular changes until periods have actually stopped.
This matters practically: if you wait until you've technically "reached menopause" to start paying attention to your cardiovascular health, you may have already gone through several years of shifting blood pressure, rising cholesterol, and changing body composition without it being flagged anywhere.

When Palpitations Need a Closer Look
Palpitations during perimenopause are usually benign, but certain patterns are worth assessing rather than assuming they're hormonal:
New palpitations accompanied by dizziness or breathlessness
Palpitations that last more than a few minutes at a time
A racing heart that doesn't settle with rest
Any palpitations alongside chest discomfort [Read more: Chest Pain in Women]
If none of these apply, occasional palpitations during perimenopause are common and not typically a cause for alarm. However, it's still worth mentioning at your next check-up, since a baseline ECG at this stage costs very little time and can rule out anything more significant with confidence.
What You Can Track Yourself
Before or alongside a formal assessment, it can help to keep a simple record of:
When palpitations happen — time of day, in relation to your cycle if still regular, and any triggers (caffeine, stress, exercise)
Blood pressure readings, if you have access to a home monitor, taken at consistent times
Sleep quality and duration
Any pattern between mood, anxiety, and physical symptoms
This isn't about self-diagnosing. It is genuinely useful information to bring to a consultation, since patterns over time are often more informative than a single snapshot.
Why This Stage Is a Good Time to Get a Baseline
Because perimenopause can begin as early as your mid-to-late 30s, and because cardiovascular risk factors can shift well before your last period, this is genuinely one of the more useful windows to establish a personal baseline — blood pressure, cholesterol, and a conversation about family history — rather than waiting for menopause to "officially" begin.
A baseline assessment during perimenopause typically includes a review of your personal and family cardiovascular history, current blood pressure and lipid profile, and where relevant, an ECG to look at heart rhythm. This isn't about running every test available; It's about establishing where you stand now, so that any future changes can be measured against something concrete rather than guessed at.
Frequently Asked Questions
Q: Can perimenopause really affect my heart before menopause even starts?
A: Yes. Hormonal fluctuations during perimenopause can affect blood pressure, cholesterol, and heart rhythm years before your final period.
Q: Are heart palpitations during perimenopause normal?
A: Often, yes — fluctuating oestrogen is a common, usually benign cause. But new, persistent, or symptom-associated palpitations are worth assessing rather than assumed to be hormonal.
Q: How do I know if I'm in perimenopause?
A: Irregular periods, new sleep disruption, mood changes, and hot flushes are common early signs, though the only definitive marker of menopause itself is 12 months without a period. A doctor can help clarify where you are in the transition if it's unclear.
Q: Should I get my heart checked during perimenopause, or wait until menopause?
A: There's real value in establishing a baseline during perimenopause, especially if you're noticing new symptoms or have risk factors — waiting until menopause "officially" begins isn't necessary.
Q: I feel anxious most of the time — how do I know if it's anxiety or my heart?
A: This overlap is genuinely common and genuinely difficult to untangle on your own, which is exactly why a basic cardiac assessment can be reassuring either way — it either identifies something worth addressing, or gives you confidence that what you're feeling is not cardiac, so you can focus on managing the anxiety directly.
Q: Does perimenopause affect cholesterol even if I haven't gained weight?
A: Yes — cholesterol changes during perimenopause are driven by hormonal shifts, not just weight, so it's possible to see rising LDL even without noticeable weight gain.
