Menstrual/Reproductive Disorder

 Gynecology Program    Reproductive Endocrine Practice  
Girls usually start their pubertal development between age 8 and 13. Girls who have not started to develop their breasts by age 13, or have not started their menstrual period by age 15 should see their health care provider for an evaluation. Menstrual problems are common among teens. However, too few menstrual periods could be caused by a mild hormone imbalance called Polycystic Ovary Syndrome (PCOS). PCOS is especially likely to be causing irregular menstrual periods if acne, excess hair growth, or weight problems exist. Irregular or lack of menstrual periods could also be caused by problems such as being underweight, excessive exercise, and stress. Girls with more than 2 months between menstrual periods should see their health care provider.

Painful menstrual periods are also a common problem for teens. If heating pads and over-the-counter medications don't relieve the pain, a health care provider may prescribe birth control pills. If bad cramps continue while taking birth control pills, a problem such as endometriosis could exist.

Girls with heavy and/or long menstrual periods may be anemic, meaning they have too few red blood cells or too little hemoglobin (oxygen-carrying protein in the red blood cells). People who are anemic need to eat more foods that contain iron and take an iron supplement. The Reproductive Endocrine Practice within the Adolescent/ Young Adult Medical Practice and the Pediatric/Adolescent Gynecology Program provide counseling and treatment services related to menstrual/reproductive disorders.

Evaluation and Diagnosis:
The evaluation of menstrual disorders includes a careful history, review of growth charts from the pediatrician, and a general physical examination. The physician will note whether the girl has acne or excess hair growth that may indicate polycystic ovary syndrome (PCOS). A gynecologic assessment is modified to fit the problem of that particular patient and may include a pelvic ultrasound as well. Frequently blood tests are obtained to measure hormone levels from the pituitary gland, the thyroid gland, and the ovaries.
Treatment:
Treatments for menstrual disorders may include observation to see if the problem will correct on its own, monthly progesterone pills, or hormone replacement (such as oral contraceptives) for irregular menstrual periods. Treatment for cramps may include a heating pad, over-the-counter medications such as ibuprofen or naproxen sodium, and prescription medications such as oral contraceptives. Girls who are still having bad cramps on birth control pills are evaluated for a problem such as endometriosis.
Research:
Researchers at Children's Hospital Boston are searching for answers to questions about:
  • What is the best age to initiate treatment for menstrual disorders?
  • What type of treatment is best for polycystic ovary syndrome?
  • How often should teens with polycystic ovary syndrome have measurement of their blood sugar? What are their risks of diabetes?
  • How can we improve information for girls with polycystic ovary syndrome?
  • When should a girl with no menstrual periods have her bone density measured? When is she at risk for low bone density and osteoporosis?
