Elevated glucocorticoid levels also contribute to low bone density in anorectics. The Scope of the Problem Bone loss is a well established consequence of anorexia. Recent studies suggest that not only is osteopenia very common, but that it occurs early in the course of the disease. Key studies have found significant decreases in bone density in anorectic adolescents. Up to two thirds of teens with the disorder have bone density values more than two standard deviations below the norm.
Studies suggest that half of peak bone density is achieved in adolescence.
Anorexia typically develops between mid to late adolescence, a critical period for bone accretion. Affected teens experience decreases in bone density at a time when bone formation should be occurring. Studies have shown that anorectic girls are less likely to reach their peak bone density and are at increased risk for osteoporosis and fracture throughout life. According to the American Anorexia Bulimia Association, approximately ten percent of eating disorder sufferers are male. While men are much less commonly affected by anorexia than women, research suggests that male victims also experience significant bone loss.
