Perimenopause

The transition is a life stage rather than a single laboratory result. Cycles may become shorter, longer, less predictable, or occasionally absent as ovulation becomes less consistent. Estradiol and progesterone can fluctuate, which means one test may not describe the overall pattern. The duration and experience of perimenopause vary widely among individuals.

People may report changes in bleeding, temperature regulation, sleep, mood, cognition, sexual function, or comfort. These experiences are not unique to perimenopause and can overlap with thyroid conditions, pregnancy, medication effects, sleep disorders, and other causes. New, severe, or unusual symptoms and bleeding patterns warrant qualified clinical assessment rather than assumption.

Menopause is identified retrospectively after a defined interval without menstruation when no other cause explains it. Perimenopause describes the changing period before that point. Hormone measurements sometimes contribute to an assessment, but age, cycle history, symptoms, contraception, medical history, and surgical history can be equally important. The term does not specify a particular intervention.

Early and later phases of the transition are sometimes distinguished by changes in cycle length and by longer intervals without menstruation. These staging conventions describe population patterns and may help clinicians communicate, but they do not predict exactly how long a phase will last or which symptoms a particular person will experience.
