In almost 90% of cases, patients are women between 10 and 29 years, and although there are few epidemiological studies, experts estimate that affects about 1 percent of the population.

A particular detail of this disease is that anorexia is perceived-weight-fat but is far below for your frame. Were also found cases of anorexia in all cultures of the world, not only in countries of the Western Hemisphere.

For its part, bulimia is a disorder in which affected are food binge and then induce vomiting, laxatives or diuretics administered and strenuous exercise for purge-your-meal.
