Researchers with Children's Hospital Boston have determined that teen girls who force themselves to throw up - even as little as one time per month - are at risk for a wide range of health disorders, including irregular menstruation.
Self-induced vomiting, which is primarily done as a form of weight control, can wreak considerable havoc on developing bodies, said S. Bryn Austin, one of the researchers who was involved in the study.
"Given that adolescence is the period of peak bone development and that normal hormonal functioning is essential for healthy bone growth, we are especially worried that these girls may be setting themselves up for a host of health problems, including low bone density, stress fractures, and osteoporosis later in life," Austin said.
The Children's Hospital study, which was published in the May 2008 edition of the
Journal of Adolescent Health, was based on an analysis of 2,791 girls who participated in the National Eating Disorders Screening Program. The report revealed the following statistics about the effect of forced vomiting:
- Twelve percent of the high school girls who were studied reported having forced themselves to throw up at least once in the previous three months.
- Girls who vomited one to three times a month were 1.6 times more likely to experience irregular menstruation than were girls who never forced themselves to throw up.
- Girls who vomited four times or more each month were 3.2 times more likely to have an irregular cycle.
According to a May 27, 2008,
New York Times article on the study, self-induced vomiting has been associated with a range of other medical problems, including electrolyte imbalances (which can lead to heart conditions), dental enamel erosion, and tears in the esophagus.
