Abstract:
OBJECTIVE:To determine if increases in core body temperature preceding most hot flashes are caused by increased metabolic rate, peripheral vasoconstriction, or central noradrenergic activation. DESIGN:Laboratory physiological study. SETTING:University medical center. PATIENT(S):Fourteen healthy, postmenopausal women reporting frequent hot flashes. INTERVENTION(S):Data were recorded for 3 hours in a temperature- and humidity-controlled room. MAIN OUTCOME MEASURE(S):Core body temperature, mean skin temperature, respiratory exchange ratio, sternal skin conductance, plasma 3-methoxy-4-hydroxyphenylglycol, and vanillylmandelic acid. RESULT(S):Twenty-nine physiologically defined hot flashes were recorded. Increases in core body temperature, measured with an ingested radiotelemetry capsule, preceded 76% of the flashes. Increased metabolic rate began after increased core temperature. Peripheral vasoconstriction did not occur. Plasma levels of 3-methoxy-4-hydroxyphenylglycol, a metabolite of brain norepinephrine, increased significantly, whereas vanillylmandelic acid, a peripheral metabolite, did not. CONCLUSION(S):Core body temperature elevations preceding menopausal hot flashes are not driven by peripheral vasoconstriction or increased metabolic rate, but probably by a central noradrenergic mechanism.
