Causes Anorexia Nervosa

Experts don’t understand what causes anorexia. It typically begins as regular fasting. Over time it will result in extreme and unhealthy weight loss. you'll use extreme dieting and food limiting tricks thanks to worry of obtaining fat.

Anorexia is a disease that is unknown for the exact cause. It's likely a combination of biological, psychological, and environmental factors.

  • Biological.It's not yet clear which genes are involved in anorexia, but it's possible that there are genetic changes that make some people more likely to develop the disorder. Some people may have a genetic tendency toward being perfectionistic and persistent - all traits associated with anorexia.

  • Psychological. Some people with anorexia may have obsessive-compulsive personality traits that make it easier for them to stick to restrictive diets and avoid food even when they are hungry. They may have an extreme drive for perfectionism, which causes them to think they are never thin enough. And they may have high levels of anxiety. Anxious people often try to restrict their food intake in order to reduce their anxiety.

  • Environmental.In modern Western culture, being thin is often seen as a successful and good thing. This pressure may be especially strong among young girls.

Risk factors Anorexia Nervosa

Anorexia is more common in girls and women, but boys and men are increasingly developing eating disorders. It's possible that this is related to the increasing social pressures boys and men face.

Anorexia is more common in teenagers than in any other age group. It can occur at any age, but it is most common during puberty, when a teen's body undergoes a lot of change. Teens may be more likely to develop anorexia if they are under pressure from their peers or feel vulnerable. People may criticize or make casual comments about someone's weight or body shape.

Anorexia is a risk factor for those who have certain things in common, such as:

  • Genetics.People who have specific genes that change may be at a higher risk of anorexia. Those with a first-degree relative who has anorexia have a much higher risk of the disorder.

  • Dieting and starvation. Eating disorders are a risk factor for developing a different kind of eating disorder. There is strong evidence that many of the symptoms of anorexia are actually symptoms of starvation- a condition in which the body does not have enough food. Starvation can affect the brain and change how you feel, including feeling anxious and having trouble thinking clearly. People who lose weight or go through periods of starvation often have difficulty maintaining their weight or may even lose it again. Decoupage may change the way the brain works in vulnerable individuals, which may perpetuate restrictive eating behaviors and make it difficult to return to normal eating habits.
