Can hot flushes start before periods stop completely?
Yes, hot flushes can begin during perimenopause, often years before periods have stopped, as hormone levels start to fluctuate.
Detailed Medical Explanation
During perimenopause, oestrogen levels become erratic, causing hot flushes even while menstrual cycles continue. This phase can last for several years, with symptoms often appearing while periods are still regular or only slightly irregular. Hot flushes are a key early sign of the menopausal transition.

Clinical Context
Many women are surprised to experience hot flushes long before their periods stop. Recognising these symptoms early helps guide care and symptom management options.
Evidence-Based Approaches
The NICE guidelines note that vasomotor symptoms such as hot flushes are diagnostic for perimenopause, even in the presence of ongoing periods. Individual assessment is advised. See NICE menopause guidance.
