Menopause

What are Hot Flashes?

Hot flashes or vasomotor symptoms are the most common complaint during the menopausal transition and early postmenopausal; they can start during the late reproductive years.

They are usually related to estrogen withdrawal, which causes a thermoregulatory dysfunction at the hypothalamus level and inappropriate peripheral vasodilation. Perspiration is a rapid heat loss mechanism that lowers the core body temperature.
Hot flashes typically begin as a sudden sensation of heat centered in the upper chest and face that rapidly becomes generalized and lasts 2-4 minutes. They are usually followed by profuse perspiration and sometimes palpitations.

Estrogen therapies restore the thermoneutral zone and largely abolish these symptoms. Some antidepressive and anti-epileptic have shown some help as well. Consult your doctor to evaluate the best treatment; don’t suffer alone.
