There is no clear-cut, single cause for any eating disorder. Many factors
seem to contribute, including social influences (such as the glorification
of thinness by the mass media), emotional issues (such as a teenager’s
striving for perfection, exposure to intensely stressful situations, and fears
of maturity, puberty, or sexuality), family factors (such as overly controlling
parents, serious emotional conflicts, or problems expressing feelings),
or poor childhood feeding and eating patterns. People who have an eating
disorder usually do not set out deliberately to have this problem. Generally,
eating disorders develop slowly, as do the signs and symptoms.
