Anorexia Nervosa: Signs, Causes, and Treatment

Anorexia nervosa is a serious mental illness and a potentially life-threatening eating disorder. With the right treatment though, recovery is possible however recognizing the warning signs early on is important.

What is anorexia?

Anorexia results in excessive weight-loss and extreme thinness caused by a very low-calorie intake or self-starvation. Though it most commonly affects adolescent girls and women, it can also impact boys of all ages, races, and ethnicities. In addition to a very low body weight, anorexia is also accompanied by an intense fear to gain weight, extreme exercise regimens, refusal to eat in public, and an obsession with controlling one’s body shape and size.

What are the causes?

The exact causes of anorexia nervosa are unknown. However, there could be a genetic predisposition as research shows the illness may run in families. Other causes include psychological, environmental, and social factors.  Usually, people who suffer from anorexia have similar traits and tend to be perfectionists and overachievers; they are generally excellent students and are active in school and community activities. Many experts believe anorexia is related to unresolved traumas or conflicts that happened in childhood; and some think sexual abuse may also be a reason.

What are the treatment options?

Recovery is possible with the correct treatment, and the earlier you seek help, the higher the likelihood of overcoming it. Anorexia treatment requires a multidisciplinary team that includes a general practitioner, a psychologist, and a dietitian. In addition to counseling, family support is vital. It is important that family members know it is not their fault and at the same time understand the eating disorder and recognize its signs and symptoms. In fact family can play a big role in recovery and maybe a huge source of support. Group therapy is also sometimes helpful as people suffering from eating disorders may find comfort and support sharing their feelings and experiences with others.
