Hot Flashes
Also known as: Vasomotor Symptoms · Night Sweats · Hot Flushes
Hot flashes are sudden, intense sensations of heat — often with flushing and sweating — driven by perimenopausal and postmenopausal narrowing of the thermoregulatory zone. They can persist for years and disrupt sleep, mood, and cognition.
What you need to know
Vasomotor symptoms reflect a narrowing of the thermoneutral zone in the hypothalamus driven by declining estradiol. They are the most disruptive perimenopausal symptom for many women, and they are highly responsive to bioidentical hormone optimization (BHRT) when candidacy is confirmed. Non-hormonal options exist but generally underperform estradiol-based pathways on symptom severity reduction. Provider-reviewed evaluation considers cardiovascular history, breast-health history, and personal goals.
