Anorexia
Anorexia, also known as anorexia nervosa, is an eating disorder in which one restricts food intake. They do not eat enough calories to support normal body functioning. Over time, their bodies will begin to shut down. They often believe they are overweight, even when they are severely underweight. Many believe our media contributes to this problem, because it places such emphasis on being thin and equates thinness with beauty.
There are other reasons people may develop anorexia. Eating disorders may also run in the family.
Anorexia nervosa causes a number of physical problems, including:

* A weakened heart muscle, low pulse, low blood pressure, and increased risk of heart failure
* Low levels of potassium, magnesium, and sodium in the body
* Anemia
* Dehydration
* Malnutrition
* Hormonal imbalances, leading to lack of menstrual period in women
* Weak muscles and fatigue
* Dizziness or fainting
* Kidney problems
* Gastro-intestinal problems, such as constipation, stomach pain, and ulcers
* Osteoporosis (brittle bones that break easily)
* Multiple organ failure
* Eating very little
* Exercising obsessively
* Severe weight loss
* Being obsessed with weight and appearance
* Depression or moodiness
* Fatigue or lethargy
* Withdrawal from social situations
* If untreated, anorexia can result in death
It is important to seek treatment as soon as the signs of anorexia are recognized, because this is a serious illness that can result in death if it is not treated. In fact, 10% of all people diagnosed with anorexia die from the condition.
Because the health problems caused by anorexia nervosa are so severe, it is important to get medical treatment if you or someone you know has signs of anorexia. Treatment for anorexia takes a long time. Hospitalization is often required at the start of treatment.

Both medical and psychological treatment is generally needed for a full recovery.
Medical treatment will address the physical conditions caused by anorexia. It will treat any heart conditions, chemical imbalances, or other health problems. In severe cases, a patient may need to be fed through a tube until they are able to begin eating on their own again.

A registered dietician will help with a healthy eating plan. Realistic goals will be set for the patient to begin regaining weight. The patient will be educated about their condition and the importance of eating properly and maintaining a healthy weight.

Psychological treatment for anorexia nervosa will assist the patient in dealing with the issues that led to the development of anorexia and will help him or her develop new coping skills. Psychological treatment is very important and without it, medical treatment is unlikely to be successful.
