Normal Menstrual Cycles Average age of menarche in the US: currently 12 years (12.8 in NHC females, and 12.2 in AA females) More cycle variability in menstrual cycles within the first 5 – 7 years following menarche. By year 1 following menarche, up to 65% of females will have a regular menstrual cycle of at least 10 periods per year. For females that reach menarche at age 13 will likely achieve regular menses at a slower rate. Approximately 50% of this population will have regular menses within 4.5 years of menarche. Normal Menstrual Cycles in Adolescents Vs Adults Adolescents: Adults: Menstrual cycle length: 21-45 days Menstrual cycle length: 28-35 days Duration of menstrual bleeding: 2-7 Duration of menstrual bleeding: 4-6 days days Median blood loss: 30ml Median blood loss: 30 ml (approximately 3 – 6 pads per day) (approximately 3 – 6 pads per day) Abnormal Uterine Bleeding Amenorrhea or lack of menses Abnormal intervals of menses Excessive volume or duration of flow **Heavy menstrual bleeding only applies to patients with heavy menses with regular, ovulatory cycles** Pictorial blood loss assessment chart (PBAC) The PBAC generates a score based on number of pads/tampons changed, percentage of saturation, and passage of blood clots. A score of >= 100 has been associated with heavy menstrual bleeding (HMB). Causes of AUB in adolescents Most common cause of AUB in adolescents within 1-2 years of menarche is anovulatory bleeding. Up to 20-30% of patients with heavier than usual menstrual bleeding will be found to have an underlying bleeding disorder, such as von Willebrand disease. Other differential diagnoses: Pregnancy, polycystic ovarian syndrome (PCOS), thyroid disorders, hypothalamic dysfunction (due to obesity, low BMI, stress, excessive exercise) and/or sexually transmitted infections (STIs).
