Menorrhagias consisting of heavy menstrual bleeding are a common complaint, encountered in approximately 15% of women between the ages of 30 and 50. Diagnosis is difficult because women present different forms of excessive menses and no simple objective ways of measuring menstrual blood loss exist. A pictorial blood assessment chart was therefore validated for a better management of heavy menstrual bleeding. In half of the cases, no gynaecologic cause is found. Therefore, blood tests should be performed aiming at identifying coagulation disorders. We present here the results of our small series. Identification of coagulation disorders may allow specific treatments. These improve the quality of life and prevent unnecessary radical measures such as notably, hysterectomies.
