Recognizing the development of anorexia can be difficult due society's acceptance of glamorizes thinness. The future anorectic may begin by skipping meals, taking only tiny portions, begins to read food labels to knows exactly how many calories and how much fat the product contains and/or begin to exercise compulsively to burn extra calories. These symptoms are usually triggered by dieting in most cases. Anorectics spend a lot of time looking in the mirror, obsessing about clothing size, and practicing negative self-talk about their bodies.
Hospitalization is recommended for anorexics with weight of 40% or more below normal, severely disturbed metabolism, severe binging and purging, signs of psychosis, severe depression or risk of suicide.There is often a high level of resistance to treatment. After the individual is physically stable, treatment includes individual and group therapy as well as re-feeding and monitoring of the patient's physical condition.
