What are the negative effects of starvation?

ANSWER:

Starvation plays havoc on the body. You burn your muscles for energy, reduce your calorie requirements, and develop nutritional deficiencies that produce bone loss, amenorrhea (no period), constipation or diarrhea, rashes, and other problems. You experience emotional changes, including irritability, social withdrawal, decreased concentration, sleep disorders, and depression. You also interfere with the body’s mechanism for regulating hunger and fullness making it likely you will binge. The effects of prolonged starvation take 6 months to 2 years to reverse.

How can I repair the damage my eating disorder did to my metabolism?

ANSWER

The metabolic effects of anorexia nervosa are largely reversed with recovery. Your metabolism will snap back as soon as you increase your calorie intake and reach the acceptable weight range. But recovery is the key, because until it occurs, you are at high risk for problems with the heart, kidneys and bones.  Eating disorders also increase the risk for suicide and death from malnutrition. Even after recovery, women with previous anorexia nervosa may have a greater than normal incidence bone fractures related to osteoporosis.
