Health Consequences
Sustained low energy availability, with or without disordered eating, can impair health. Psychological problems associated with eating disorders include low self-esteem, depression, and anxiety disorders. Medical complications involve the cardiovascular, endocrine, reproductive, skeletal, gastrointestinal, renal, and central nervous systems. The prognosis for anorexia nervosa is grave with a sixfold increase in standard mortality rates compared to the general population. In one study, 5.4% of athletes with eating disorders reported suicide attempts. Although 83% of anorexia nervosa patients partially recover, the rate of sustained recovery of weight, menstrual function and eating behavior is only 33%.
Amenorrheic women are infertile, due to the absence of ovarian follicular development, ovulation, and luteal function. Consequences of hypoestrogenism seen in amenorrheic athletes include impaired endothelium-dependent arterial vasodilation, which reduces the perfusion of working muscle, impaired skeletal muscle oxidative metabolism, elevated low-density lipoprotein cholesterol levels, and vaginal dryness.
Due to low bone mineral density that declines as the number of missed menstrual cycles accumulates, and the loss of BMD may not be fully reversible. Stress fractures occur more commonly in physically active women with menstrual irregularities and/or low BMD with a relative risk for stress fracture two to four times greater in amenorrheic than eumenorrheic athletes. Fractures also occur in the setting of nutritional deficits and low BMD.

Famous quotes containing the words health and/or consequences:
“Criticism is often not a science; it is a craft, requiring more good health than wit, more hard work than talent, more habit than native genius. In the hands of a man who has read widely but lacks judgment, applied to certain subjects it can corrupt both its readers and the writer himself.”
—Jean De La Bruyère (1645–1696)
“We are still barely conscious of how harmful it is to treat children in a degrading manner. Treating them with respect and recognizing the consequences of their being humiliated are by no means intellectual matters; otherwise, their importance would long since have been generally recognized.”
—Alice Miller (20th century)
