[Eating disorders in sports: risk factors, health consequences, treatment and prevention]

Eating disorders appear with relative frequency in sports, such as gymnastics, figure skating or resistance sports, in which weight control is important. Their incidence is greater in women, frequently appearing a low self-esteem, a distorted body image in which the body is perceived with an excess of weight, inefficiency, perfectionism and a sense of control loss, with compensatory attempts exerted through food manipulation and the use of inadequate methods of control weight. Frequently, they are associated in female athletes to irregularities of the menstrual cycle, reduction of the bone mineral density and osteoporosis, giving rise to so-called female athlete triad. Cardiovascular problems, a greater incidence of fractures, and muscular power and resistance losses which impair performance, can also develop. Between the risk for their appearance are attempts to lose weight, often by recommendation of the coach, increases of training loads associated to weight losses, characteristics of the personality that take to excessive preoccupation by body image, or injuries and traumatisms. Treatment requires a multidisciplinary approach, with participation of physicians, psychologists/psychiatrists, nutricionists, coaches and family, being specially important the emphasis on preventive measures.
