A prospective study was conducted amongst Hong Kong Chinese women to determine the incidence of acute menopausal symptoms following surgical menopause. Cases where a laparotomy was performed for other indications were used as controls. Hot flushes and sweating developed in 8/33 (24.2%) and 6/33 (18.2%), respectively, of those women having had a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Whilst vasomotor symptoms were more frequent in those women who had undergone a surgical menopause than in the controls, women in this population were shown to suffer fewer symptoms than has been demonstrated in Caucasian women. Although this study does not help to explain why such differences exist, the relative absence of symptoms may contribute to the low demand for hormone replacement therapy in Hong Kong and other countries where climacteric symptoms are relatively infrequent.
