A study has been made of menstrual blood loss measured in 50 women with unexplained heavy loss (more than 80 ml). Twelve of these women had an average menstrual loss greater than 200 ml, five women in excess of 450 ml. There was no relation between the duration of menstruation and the total menstrual blood loss. Compared to women with normal menstrual loss there was no difference either in the proportion of total menstrual loss passed on each day of menstruation in women bleeding heavily (92 per cent of the total menses being lost in the first three days) or in the coefficient of variation for menstrual blood loss from one period to the next. There was a reduction in menstrual blood loss in the first period following uterine curettage but no effect thereafter.
对50名不明原因月经过多（超过80毫升）的女性进行了月经失血量的研究。其中12名女性平均月经失血量超过200毫升，5名女性超过450毫升。月经持续时间与月经总失血量之间没有关系。与月经失血正常的女性相比，月经过多的女性在月经期间每天排出的月经总失血量比例（月经头三天失血占总月经量的92%）或不同月经周期之间月经失血量的变异系数均无差异。刮宫术后的第一个月经周期月经失血量有所减少，但此后没有效果。
