Perimenopause

Perimenopause is the transitional phase leading up to menopause, when hormone levels begin to fluctuate. Changes in sweating, including hot flashes, can start during this period.

This phase can last several years before menstrual cycles finally end, and hormone levels shift unevenly throughout it. Those fluctuations can trigger hot flashes and night sweating even before menopause is reached. Because cycles may still occur, the sweating changes can appear alongside other evolving symptoms. It is often when people first notice temperature-related sweating shifts. The uneven nature of the hormone changes means the sweating can be unpredictable from week to week. Recognizing this phase helps explain new sweating that appears while periods are still happening. The prefix peri means around, marking the time around menopause. Cycles often become irregular during this phase before stopping. The sweating it brings shares the same vasomotor character as that of menopause itself.

In practice

Occasional hot flashes and night sweats appearing while periods are still happening, though irregular, suggest perimenopause. The fact that these episodes come and go unpredictably fits the uneven hormone shifts that define this transitional phase. Someone in their forties noticing new waves of heat, with cycles becoming irregular, may be entering this stage.
