A sudden pounding, fluttering, or racing heart is one of the most alarming symptoms of perimenopause — and one of the most common. It can arrive out of nowhere, sometimes with a hot flash, sometimes at night, sometimes with a wave of anxiety, and it naturally makes you fear something is wrong with your heart. For most women, perimenopausal palpitations are harmless and hormone-driven. But because the heart is involved, it is important to know both why they happen and the warning signs that do need a doctor.
Why Hormones Make Your Heart Race
Oestrogen influences the cardiovascular system and the nervous system that controls heart rate. As oestrogen fluctuates and falls in perimenopause:
The nervous system becomes more reactive. Oestrogen helps keep the body’s “fight or flight” system in balance. As it swings, this system becomes more easily activated, releasing adrenaline that speeds up and strengthens the heartbeat — felt as a pounding or racing heart.
Palpitations cluster around hot flashes. During a hot flash, the heart rate naturally rises as the body works to shed heat. Many women feel this as palpitations, either just before or during a flash.
Anxiety amplifies it. Perimenopause heightens anxiety, and anxiety itself causes palpitations. Then the palpitations cause more anxiety — a loop where a racing heart triggers fear, which speeds the heart further.
Night-time and blood sugar. Palpitations often feel worse at night when it is quiet and you notice your body more, and blood-sugar dips or stimulants like caffeine can set them off.
What It Feels Like
Women describe palpitations as: a pounding or thumping heartbeat, a fluttering in the chest, a sensation of the heart skipping or adding a beat, or a sudden racing that lasts seconds to a few minutes and then settles. They often come and go, may pair with a hot flash or a wave of anxiety, and frequently strike at night.
What Helps
Reduce stimulants. Caffeine and nicotine directly provoke palpitations. Cutting back on tea, coffee, and energy drinks, especially in the afternoon, often makes a clear difference.
Limit alcohol. Alcohol is a common trigger for palpitations and for the night-time version.
Steady your blood sugar. Regular meals with some protein prevent the blood-sugar dips that release adrenaline.
Calm the nervous system. Slow breathing — a longer out-breath than in-breath — during an episode helps settle the heart. Regular breathing practices, yoga, and consistent exercise lower baseline reactivity over time.
Address anxiety. Because anxiety and palpitations feed each other, calming the mind reduces both. Knowing that the sensation is usually benign itself takes some of the fear, and therefore some of the fuel, out of the loop.
Protect sleep. Tiredness heightens the whole system, so better sleep means fewer episodes.
Consider the hormonal angle. Since the root is hormonal, treatments that steady the system — including HRT for some women — can reduce palpitations along with hot flashes. Worth raising with your gynaecologist.
When to See a Doctor
Palpitations are common in perimenopause, but the heart is one area where it is always worth being checked rather than assuming. See a doctor for a routine assessment if you are having palpitations at all that concern you — it is reasonable to have your heart checked once to rule things out and get reassurance, which is valuable in itself.
Seek urgent medical help — call 112 — if palpitations come with any of these:
- Chest pain, pressure, or tightness.
- Breathlessness or difficulty breathing.
- Fainting, near-fainting, or severe dizziness.
- Palpitations that are very fast, very prolonged, or do not settle.
- A very irregular heartbeat, or a pounding that comes with sweating and a feeling that something is seriously wrong.
Also see a doctor promptly (not emergency) if palpitations are frequent, getting worse, or you have a known heart condition, high blood pressure, thyroid problems, or a family history of heart disease. An overactive thyroid, which is common at this age, can also cause palpitations and is easily tested.
The reassuring reality is that most perimenopausal palpitations are benign and hormone-driven. But because it involves your heart, getting checked once for peace of mind is exactly the right thing to do — and then you can manage the hormonal triggers with confidence.
