Messages are all around us of the benefits of a healthy diet and regular exercise. Advice on how to do that is also readily available. However, an obsession with losing weight and exercising can lead to anorexia. The emotional and physical consequences are serious. A person with anorexia does not realize the dangers (including hair loss, fatigue and weakness, dehydration, weakened immune system, heart trouble, even death) of denying food to their body. It's also important to know that about 50% of people with anorexia also develop bulimia. (See our Bulimia Assessment for help if you think you or a loved one may have bulimia.) Answer these few questions to learn more about the signs of anorexia and help you determine if your child or someone you know may have anorexia.
