When do hot flushes start during perimenopause?
Hot flushes typically begin in the early stages of perimenopause, often several years before the final menstrual period, as hormone levels begin to fluctuate.
Detailed Medical Explanation
Hot flushes commonly start during the early perimenopausal years, a time marked by unpredictable fluctuations in oestrogen levels. These hormonal changes can trigger vasomotor symptoms even when periods are still regular or only slightly irregular. Research shows many women begin to experience hot flushes in their 40s, although the onset varies. See the NHS guide on menopause symptoms for more details.
Clinical Context
Perimenopausal symptoms, including hot flushes, often overlap with ongoing menstrual cycles. Women should be aware that symptoms can begin years before menopause is officially diagnosed. Early support and advice can help with symptom management.
Evidence-Based Approaches
Monitoring menstrual changes and symptom patterns is recommended. The NICE guidelines advise considering perimenopausal status if women present with vasomotor symptoms and changing periods. For further clinical details, see NICE guidance on menopause.
