BETHESDA, MD — May 29, 2002 —
Irregular menstrual periods in young women may be a warning sign of a hormonal shortage that could lead to osteoporosis, according to a preliminary study by researchers at the National Institute of Child Health and Human Development (NICHD).
The study, of women with a condition known as premature ovarian failure, appears in the May issue of Obstetrics and Gynecology.
Premature ovarian failure occurs when the ovaries stop producing eggs and reproductive hormones well in advance of natural menopause.
An estimated one percent of American women develop the condition by age 40. Most of the women who took part in the study reported a history of amenorrhea — absence of a menstrual period for three months or more — before they were later diagnosed with premature ovarian failure.
Moreover, the majority of these young women had not considered amenorrhea as a significant health problem.
