Psychological Emotional abuse, rejection issues, and anxiety may contribute to poor body image. Some young females may have an obsessive-compulsive component to their personality and feel the need to adhere to strict diet and exercise regimens.

Environment The is a strong link to TV ads, magazine ads, and image to look good. It is all around us and we often feel like in order to be of importance, we have to be thin. In younger people, there is mounting peer pressure over looks.

Biological There may be a genetic component to the disorder. Some people are more genetically inclined to perfectionist tendencies. They tend to be more sensitive in nature and persevere in everything they do. These biological traits are strongly linked to people with anorexia nervosa.

Risk Factors for Anorexia Nervosa

Risk Factors for Anorexia Nervosa

The risk factors for anorexia are usually attributed to the following factors:

Age Group Teenagers are more at risk for anorexia because they are dealing with changes in puberty and growth. Emotionally teens are more sensitive to peer pressure and negative comments about their bodies.
Females Boys are at risk for anorexia, but there is a higher rate of females that suffer from eating disorders.
Genetic Tendencies There may be genetic links to eating disorders and it may run in families.
Changes in Weight Even small weight gains can cause someone to go on an extreme diet. When someone goes into starvation mode, they may change their brains response to food. It has been found that people with long standing anorexia cannot go back into normal eating patterns without intense therapy.
Life Trauma & Changes Moves, new schools, new jobs, or relationship issues can trigger an eating disorder.
Athletes or Performing Artist Being in a position where you have to maintain a certain weight can trigger an eating disorder. This is common among models, dancers, ice skaters, and gymnasts.

Mental Examination A mental workup can evaluate thoughts about eating, emotional status, and history of emotional trauma that may be linked to the disorder.
Radiology Studies Bone density may be checked. EKG’s can be done to see if there are any abnormal heart rhythms due to electrolyte losses.

Treatments for Anorexia Nervosa

Anorexia nervosa is successfully treated with therapy, medication, and dietary modifications. Treatment often is lifelong and sufferers are prone to relapse if therapy is not continued. There needs to be an adequate support group and behavioral therapy regarding food issues.

Medications used are usually anti-depressants, anti-anxiety medications, and sometimes appetite stimulants. In serious cases where there is significant malnutrition, sufferers may need inpatient hospitalization with tube feedings, intravenous nutrition, and vitamin supplementation.

Here are a few tips to use with kids and teens:
Encourage Healthy Eating and Exercise> Keep a positive outlook when talking about eating health and exercising. Stress that it is for good health and not looks.
Promote a Healthy Self Image Never call a child fat or say they will get fat. Teach them they are beautiful no matter what and what is inside is most important
Do Not use Food as a Reward or Punishment Never take away food if a child does something wrong or offer food if they are good.
Model Healthy Behaviors The best way to teach our kids is by doing. When they see us thinking about ourselves in a healthy way, eating and exercising right they will hopefully follow our lead.
