Anorexia Nervosa or known as “Anorexia” is a life-threatening disease that causes someone to obsess about their weight and slim figure to the point of not eating or severely reducing their calorie intake. Someone suffering from anorexia will use extreme measures in order to maintain a low body weight such as laxatives, purging, diuretics, diet aids, low calorie intake or excessive exercise.

Risk Factors
Eating disorders are a complex disease and can affect lots of different people. Researchers have found some similarities in people affected with anorexia and many factors can contribute to someone developing it including environmental, biological, psychological and sociocultural.
Some studies show that there is a correlation between serotonin levels and someone developing anorexia. Serotonin is a chemical in the brain that effects learning, mood and sleep as well as other things. Serotonin can affect a person’s eating habits or behaviors causing them to become anorexic.
The pressure from a person’s society to be thin and beautiful can play a role in them developing an eating disorder.
Biological Factors Studies have shown that there are genetic components that contribute to someone developing an eating disorder. A person with a family member who suffers from an eating disorder are 7-12 times more likely to develop one themselves. Inherited characteristics such as obsessive-compulsive disorder, overthinking or other mental health disorders can cause a person to overly obsess about weight or being thin.
Psychological Factors someone who suffers from mental health disorders such as anxiety, depression or other mental health disorders may be more likely to develop an eating disorder. People who have suffered from trauma may use control over their eating habits in order to cope with the stress or anxiety.
Sociocultural Factors The need to remain thin and beautiful can be attributed to social norms and expectations that a person look a certain way to be attractive or worthy. There is a lot of pressure for people to look good and often celebrities or other people in the media will go to extreme measures to lose weight.
Anorexia Nervosa Statistics
It can be difficult to get accurate results of studies on anorexia because many people who suffer from it do not want to admit to having it. It shows a lack of control and vulnerability that a lot of people can’t endure.
People with anorexia will often do things to hide the disease such as wearing baggy clothing, pretending to eat or deny symptoms that they are experiencing.
Anorexia is more common among women and men only make up 10% of total sufferers. Statistics show that somewhere between 1-5% of all adolescent females or young women may develop anorexia at some point in their life. It is most common among teenagers and young adolescents, but it is not unheard of for older people to develop it. It is not as common among people over the age of 40 but it does happen. The average age that someone develops the disease is 17 and generally people under the age of 10 do not ever have it.
Diagnosing
If your doctor suspects that you have anorexia, they will typically perform some tests to determine whether you have it. These tests include:
Physical Exam a physical exam from your doctor that includes getting your height and weight checked, vital signs such as blood pressure, heart rate and temperature.
Lab Testing blood tests or other lab testing to check proteins and electrolytes may be performed. Your liver, kidney and thyroid may also be evaluated.
Psychological Evaluation a physician will ask detailed questions about your thoughts, feelings and habits around eating. There may be a self-assessment with many questions.
Other testing there may be x-rays done in order to check bone density, bone fractures and to check for heart problems or pneumonia.
