Januari 17, 2010 Dear Doctor, Could you please advise me on treatment for my bothersome menstrual bleeding. I’m 46 years of age and mother of 3 children. I hardly can keep up my job as a teacher due to the prolonged bleeds and a lack of energy after a period. Yours sincerely, Mrs Jones © PHMvdW 2010

Dysfunctional Uterine Bleeding describes the spectrum of abnormal menstrual bleeding patterns that occur in women secondary after anovulation or oligo- ovulation and where no pelvic pathology or medical illness is present.
