Hot flushes & night sweats
Why it happens: Falling oestrogen narrows the temperature range your brain treats as comfortable, so small changes trigger a full flush.
What helps: Trigger tracking, layered clothing, paced breathing, cooling the bedroom, and HRT or non-hormonal prescriptions for moderate to severe symptoms.
Sleep problems & insomnia
Why it happens: Night sweats, a more fragile sleep architecture and rising anxiety combine into 3am waking.
What helps: A fixed wake time, a cool dark room, limiting alcohol, CBT for insomnia, and treating night sweats at the source.
Mood changes & anxiety
Why it happens: Hormone fluctuation affects serotonin and cortisol regulation — often before periods change.
What helps: Strength and aerobic movement, sleep repair, therapy, and a clinical review if low mood persists.
Brain fog & memory
Why it happens: Oestrogen supports verbal memory and processing speed; the dip is usually temporary.
What helps: Sleep, single-tasking, written prompts, exercise, and ruling out thyroid or iron deficiency.
Joint pain & fatigue
Why it happens: Oestrogen has an anti-inflammatory role, so aches in hands, knees and shoulders are common.
What helps: Daily movement, resistance training, protein intake, vitamin D and a clinical check for other causes.
Vaginal dryness & low libido
Why it happens: Thinning tissue and reduced blood flow cause dryness, discomfort and urinary changes.
What helps: Vaginal moisturisers, local oestrogen (very low systemic absorption), and an open conversation with a clinician.
Irregular or heavy periods
Why it happens: Cycles shorten, lengthen and skip as ovulation becomes unpredictable.
What helps: Cycle tracking, iron checks, and prompt review of very heavy or post-menopausal bleeding.
Weight & metabolic changes
Why it happens: Muscle loss and fat redistribution to the abdomen shift how your body uses energy.
What helps: Resistance training twice weekly, protein at each meal, sleep, and cardiovascular risk screening.
