hot flash

hot flash

a transient sensation of warmth experienced by some women during or after menopause. Hot flashes result from autonomic vasomotor disturbances that accompany changes in the neurohormonal activity of the ovaries, hypothalamus, and pituitary. The exact causative mechanism is not known. All menopausal women do not experience hot flashes; among those who do, the frequency, duration, and intensity vary widely. Although physically harmless, the symptom may be extremely disturbing or, rarely, disabling. Hot flashes may be alleviated by cyclic or continuous administration of exogenous estrogen. Also called hot flush. See also menopause.
A symptom complex afflicting 80–85% of middle-aged women, first occurring during perimenopause, continuing with decreased intensity for years, appearing as transient waves of erythaema and uncomfortable warmth beginning in the upper chest, face and neck, followed by fine sweating and chills. Hot flashes are precipitated by emotional stress, meals and environmental cues, and are more intense if ovaries are surgically removed than if the decline of ovarian function is less abrupt
Mechanism Hot flashes are attributed to central alpha2-adrenergic activity
Aetiology Idiopathic, due to response of autonomic nervous system to decreased oestrogens; they are responsible for osteoporosis, atrophy of vaginal epithelium, leukorrhea and pruritus
Management While hormones—e.g., oestrogens in women and androgens in men—ameliorate symptoms of age-related hormonal decline, they are contraindicated in women with breast cancer, and in men with prostate cancer; megestrol acetate decreases hot flashes by 85%—vs. 20% with placebos. Oestrogen replacement ‘drives’ proliferation of endometrial tissue, which may result in adenomatous hyperplasia and occasionally endometrial carcinoma
Note: Hot flashes occur in eunuchs and in most men who have been acutely deprived of testosterone as in castration, a therapeutic modality for advanced prostate carcinoma; diethylstilbestrol may stop the flashes, but exacerbates cardiovascular disease and blood clots; in Europe, cyproterone acetate is used
