Athletes are often under a lot of pressure to be at a certain weight for some sports. These sports include dance, gymnastics, diving, or figure skating. This often causes athletes to lose weight in unhealthy ways (skipping meals, using diet pills or laxatives, or vomiting). Unhealthy dieting can lead to unhealthy eating habits or eating disorders (anorexia or bulimia). Unhealthy dieting and heavy exercise may also affect menstrual cycles and bone health in women. It may also affect the growth and development of young athletes.
