Gynec - Amenorrhea
harry206 - 05-14-09 09:24
A 35-year-old African-American marathon runner presents to the gynecologist complaining of secondary amenorrhea that developed three months ago. Her cycles are normally 28 days long, and her menses last three to five days with moderate flow. One year ago, the woman adopted a vigorous exercise regimen that lasted between three and five hours every day. Since then, her BMI has declined from 23.4 to 16.5. She has been winning many local races and is considering increasing the difficulty of her exercise regimen, but would like to address the issue of her amenorrhea first. Physical examination reveals a thin woman with well-defined musculature but is otherwise unremarkable. Pregnancy test is negative. What is the most likely etiology of her amenorrhea?
