It arrives without warning — a tight chest before a meeting that never used to bother you, a 2am spiral over an email, a low hum of dread with nothing to pin it to. If you’ve spent decades as a fairly steady person and suddenly feel like you’re vibrating, the most unsettling part is the question: where did this come from? For many women in their late 30s and 40s, anxiety that seems to appear out of nowhere can be a sign of perimenopause.

The link between hormones and anxiety

Oestrogen and progesterone don’t just affect your cycle — they influence the brain systems that keep you calm. Oestrogen supports mood-regulating chemicals like serotonin, and progesterone has a naturally calming effect. As these hormones fluctuate through perimenopause, that internal “steadying” can waver, leaving you more prone to worry, racing thoughts and a fight-or-flight response that fires too easily.

How perimenopausal anxiety can feel

• A racing heart or tight chest in ordinary situations
• Waking at 2–3am with your mind spinning
• A constant background hum of worry or dread
• Feeling overwhelmed by things you used to take in your stride
• Physical symptoms — nausea, restlessness, shortness of breath

It’s not “just in your head”

Being told to manage stress better, when something genuinely feels different in your body, is frustrating and dismissive. Hormonal anxiety is real and recognised. It can also coexist with other causes, so it’s worth getting a proper assessment rather than assuming you simply have to cope.

How The M Clinic can help

We take your symptoms seriously and look at the whole picture — hormones, sleep, thyroid and lifestyle. From there we discuss evidence-based options, which may include MHT, non-hormonal treatments and supportive strategies, tailored to you.
