Anorexia Nervosa: Causes, Warning Signs & Treatment

Anorexia Nervosa: Causes, Symptoms, Signs & Treatment


Anorexia nervosa is a type of eating disorder. People who have anorexia have an intense fear of gaining weight. They severely limit the amount of food they eat and can become dangerously thin.

Anorexia affects both the body and the mind. It may start as dieting, but it gets out of control. You think about food, dieting, and weight all the time. You have a distorted body image. Other people say you are too thin, but when you look in the mirror, you see your body as overweight.



Anorexia usually starts in the teen years. It’s much more common in females than males. Early treatment can be effective. The earlier it is treated, the better the chances someone can recover from anorexia. Untreated anorexia can lead to starvation and serious health problems, such as bone thinning (osteoporosis), kidney damage, and heart problems. Some people die from these problems.

If you or someone you know has anorexia nervosa, get help right away. The longer this problem goes on, the harder it is to overcome. Over time and with treatment, a person with anorexia nervosa can feel better and stay at a healthy weight.

What causes anorexia nervosa?

Eating disorders are complex, and experts don’t really know what causes them. But they may be due to a mix of genetics, family behaviours, social factors, and personality traits. You may be more likely to have anorexia if:

  • Other people in your family have an eating disorder, such as anorexia or bulimia nervosa.
  • Your job or you do a sport that stresses body size, such as ballet, modelling, or gymnastics.
  • You are the type of person who tries to be perfect all the time, never feels good enough, or worries a lot.
  • You are dealing with stressful life events, such as divorce, moving to a new town or school, or losing a loved one.

Sub-types of anorexia nervosa

There are two sub-types of anorexia and both are very serious mental illnesses that require treatment.

Restricting Sub-type

 

People with the restricting sub-type place severe restrictions on the amount and type of food they consume. These includes restrictions of certain food groups such as carbohydrates and fats. They also do calorie counting, skipping meals, and/or obsessive rules and also rigid thinking (e.g. only eating food that is one colour). These restrictive behaviours around food may be accompanied by excessive exercise.

 

Binge Eating/Purging Sub-type

People with this sub-type also place severe restriction on the amount and type of food they consume. In addition to this the person will display purging behaviour. They may also engage in binge eating. Binge eating involves eating a large amount of food and also feeling a ‘loss of control’. Purging behaviour involves self induced vomiting, or deliberately misusing laxatives, diuretics or enemas to compensate for eating food.

What are the symptoms?

People who have anorexia often strongly deny that they have a problem. They don’t see or believe that they do. It’s usually up to their loved ones to get help for them. If you are worried about someone, you can look for certain signs.

How is anorexia diagnosed?

If your doctor thinks that you may have an eating disorder, he or she will compare your weight with the expected weight for someone of your height and age. He or she will also check your heart, lungs, blood pressure, skin, and hair to look for problems caused by not eating enough. You may also have blood tests or X-rays.



Your doctor may ask questions about how you feel. It is common for a treatable mental health problem such as depression or anxiety to play a part in an eating disorder.
