In Detail
The earliest signs of perimenopause are often subtle and easy to attribute to stress, parenting, or a demanding career. Cycles may arrive a few days early or late, bleeding may become heavier or lighter, and premenstrual symptoms may intensify. Sleep frequently becomes the first thing to break — women wake at 2 or 3 a.m. and cannot easily return to sleep.
Other early signals include new or worsening anxiety, irritability, brain fog, breast tenderness, declining libido, occasional hot flashes or night sweats, and weight gain that does not respond to previous diet and exercise patterns. Many women describe simply 'not feeling like themselves.'
These symptoms can overlap with thyroid disease, iron deficiency, sleep apnea, and primary mood disorders. A thoughtful workup distinguishes perimenopause from its mimics and identifies which contributors need treatment.
