Impact of anorexia, bulimia and obesity on the gynecologic health of adolescents.
Dieting behaviors and nutrition can have an enormous impact on the gynecologic health of adolescents. Teenaged patients with anorexia nervosa can have hypothalamic suppression and amenorrhea. In addition, these adolescents are at high risk of osteoporosis and fractures. Unfortunately, data suggest that estrogen replacement, even in combination with nutritional supplementation, does not appear to correct the loss of bone density in these patients. Approximately one half of adolescents with bulimia nervosa also have hypothalamic dysfunction and oligomenorrhea or irregular menses. Generally, these abnormalities do not impact bone density and can be regulated with interval dosing of progesterone or regular use of oral contraceptives. In contrast, the obese adolescent with menstrual irregularity frequently has anovulation and hyperandrogenism, commonly referred to as polycystic ovary syndrome. Insulin resistance is thought to play a role in the pathophysiology of this condition. While current management usually involves oral contraceptives, future treatment may include insulin-lowering medications, such as metformin, to improve symptoms. Because all of these patients are potentially sexually active, discussion about contraception is important.
