Perimenopause isnât âjust in your headâ.
Itâs a real, biological transition. Hereâs whatâs actually happening in your body đ
Perimenopause is the phase leading up to menopause (Officially when you have had 12 consecutive months without a period), when your ovaries gradually produce less estrogen and progesterone. But the key word is fluctuate.
Hormones donât just decline smoothly, they swing up and down.
⨠Hot flashes & night sweatsâ¨As estrogen levels drop or suddenly shift, it affects your brainâs temperature control center (hypothalamus). Your body can misread normal temperature as âtoo hot,â triggering sweating, flushing, and chills.
đ¤ Irritability, mood swings & anxietyâ¨Estrogen supports serotonin and dopamine (the âfeel-goodâ brain chemicals.) When estrogen fluctuates, these neurotransmitters can dip, leading to mood changes.â¨Lower or inconsistent progesterone (your calming hormone) can also increase anxiety and disrupt sleep.
đ¤ Sleep problemsâ¨Progesterone has a natural sedative effect. As it declines, falling and staying asleep can become harder, and night sweats donât help.
đ§ Brain fogâ¨Estrogen plays a role in memory, focus, and cognitive clarity. Fluctuations can temporarily affect concentration and recall.
đ Irregular periodsâ¨Ovulation becomes less predictable. Without consistent ovulation, progesterone levels drop, cycles shorten, lengthen, or become heavier or lighter.
This phase can start in your 40s (sometimes late 30s) and last several years before menopause is reached.
Youâre not âcrazy.â Youâre in transition - hormonally, neurologically, and metabolically.
If youâre in this season, know this: your symptoms are valid, support is available, and your body isnât broken, itâs recalibrating.
