Perimenopause symptoms: the full list, and what they mean

Well established

Changes in cycle length and flow. Usually the first objective sign. A persistent seven-day difference between consecutive cycles marks the early transition.

Hot flushes and night sweats. The most studied symptom of the transition. Median total duration around seven and a half years, and around ten years for Black women in the SWAN cohort.

Disrupted sleep. Frequently waking in the small hours rather than difficulty falling asleep. Sometimes driven by night sweats, often not.

Mood changes. New or worsened anxiety, irritability and low mood. Risk of a depressive episode genuinely increases during the transition, particularly in women with a previous history.

Vaginal dryness, discomfort and pain during sex. Grouped clinically with urinary symptoms as the genitourinary syndrome of menopause. Distinct from the rest of the list because it tends to progress rather than resolve, and because it responds well to specific local treatment that many women are never offered.

Urinary symptoms. Increased urgency, frequency and recurrent urinary tract infections.

Commonly reported, well recognised, less precisely quantified

Difficulty with word recall and concentration. Widely described and increasingly taken seriously. Studies of cognition through the transition suggest the changes are real and generally do not persist.

Joint and muscle aches. Very commonly reported. Oestrogen has effects on connective tissue and inflammation, and stiffness that is worst in the morning is a familiar description in this decade.

Weight redistribution towards the abdomen. Well documented. The shift in where fat sits appears more hormonally driven than the total gain, which tracks ageing.

Heart palpitations. Common and usually benign, but the combination with chest pain, fainting or breathlessness on exertion is assessed rather than assumed.

Headaches or worsened migraine. Often tracks hormonal fluctuation, and frequently improves once the transition completes.

Hair thinning and skin changes. Falling oestrogen affects collagen and hair follicles. Sudden or patchy hair loss is a different problem and should be seen.

Reduced libido. Multi-factorial: hormonal, but also sleep, mood, pain during sex, and relationship context all contribute.

Reported, but treat the internet’s certainty with caution

Several symptom lists circulating online run to 34 or more items, including burning mouth, electric shock sensations, itchy skin, tinnitus and body odour changes. Some women describe these genuinely. The evidence linking them specifically to the hormonal transition, as opposed to ageing or a separate condition, is thin.

We would rather tell you that than pad a list. If you have one of these and it bothers you, it deserves proper assessment on its own merits rather than being filed under hormones and dismissed.

The point about pattern

Almost nothing on this list is exclusive to perimenopause. Fatigue, weight gain, low mood, hair thinning and cycle change are all also produced by thyroid disease. Palpitations, breathlessness and exhaustion are all produced by iron deficiency, which heavy perimenopausal bleeding causes.

This is why any decent assessment considers the whole picture and why blood tests for thyroid function and a full blood count are reasonable early steps. It is also why our symptom pages each carry a section on what else could cause the same thing.

A platform that told you everything in your forties was hormonal would not be worth trusting.
