Left untreated, some people with severe anorexia may die from malnutrition or cardiovascular problems. Intense fear of weight gain, even if currently underweight. Strong reliance on body weight or shape in determining self-worth. Denial of being underweight, or denial of the seriousness of being underweight. In women, missing three or more periods in a row when pregnancy has been ruled out.
Treatment is critically important.
In most instances, anorexia is treated with behavioral therapy. In severe cases, hospitalization may be necessary.
