Anorexia nervosa

Anorexia nervosa (usually just called anorexia) is an eating disorder.
People with anorexia think that they are fat, or desperately fear becoming fat even if they are very skinny. To try to lose weight, anorexics do not eat enough. When they do eat, they do not eat the amount of food their body needs, in an effort to avoid gaining weight. This causes them to lose too much weight too quickly. This is very harmful to a person's body. There are various treatments for anorexia. One example is the Maudsley Method. This type of treatment is for patients who are 18 or younger. Two thirds of adolescent anorexia patients are 'recovered' at the end of this treatment. People with anorexia are more likely to die than people with any other mental illness.
Diagnosis
Doctors use the Diagnostic and Statistical Manual of Mental Disorders to make a medical diagnosis and decide if a person has anorexia or not. Four signs of anorexia are listed in the manual. People do not have to show all four signs for the doctor to decide that they have anorexia.
- Signs of anorexia
- People with anorexia do not want to keep a body weight and BMI that is normal for their age and height.
- People with anorexia think that they are fat. They are afraid of gaining weight.
- People with anorexia have low self-esteem because of the shape or weight of their body. Also, they do not think that low body weight is a problem.
- A woman with anorexia might not have their period multiple months in a row (one period is sometimes called a menstrual cycle). They also must make sure the woman is not pregnant and has not had their periods stop permanently due to their age, which is called menopause.
Symptoms of anorexia
- Rapid, unexplained weight loss
- Refusal to maintain a healthy weight
- Low self-esteem and distorted self-image
- Frequent weighing, "body-checking", or negative comments on appearance
- Amenorrhoea, the loss of menstrual periods
- Low body temperature
- Low pulse, blood sugar and blood pressure
- Depression
Dangers of anorexia
- Total self-starvation
- Heart attack or heart failure
- Kidney failure[1]
- Electrolyte imbalance
- Muscle and organ damage (when the body has no fat to live off of, it begins to digest muscle and tissue)
- Suicide[2]
Causes
There is no single cause of anorexia. Researchers believe that it is caused by a combination of biological and environmental factors. It has been linked to the media. Many people think that anorexia is caused by wanting to be thin like models in magazines. However, it is not that simple.
People who develop anorexia tend to be perfectionistic. They are also more likely to have problems socializing.[1] There has been research about the link between anorexia and autism spectrum disorder (ASD), a disorder that involves problems with socializing. Another symptom of autism spectrum disorder is OCD, which has also been linked to anorexia.[2] Starvation is known to create antisocial behavior so there needs to be research that compares those traits in anorexics with people who have recovered.
