Causes of an eating disorder

Researchers are unsure of the underlying causes and nature of eating disorders. Unlike a neurological disorder, which can generally be identified with a specific injury to the brain, an eating disorder probably involves abnormal activity distributed throughout the neural systems.

More researchers are using tools from modern neuroscience and modern psychology to better understand eating disorders. Also, they appear to be inherited, so research on genetic factors continues.

Other psychological, interpersonal, and social factors can play a role in eating disorders. Psychological factors that can contribute include low self-esteem, feelings of inadequacy or lack of control in life, depression, anxiety, anger, or loneliness.

Interpersonal factors include troubled personal and family relationships, difficulty expressing emotions and feelings, a history of teasing or ridiculing based on size and weight, or a history of physical or sexual abuse.

Social factors that may contribute include cultural pressures that glorify thinness and place value on obtaining the ‘perfect’ body, limited social definitions of beauty that include only women and men of specific body shapes and weights, or cultural norms that value women. people on the basis of physical appearance and not qualities and internal strengths.

Treatments and therapies for the improvement of an eating disorder

Proper nutrition, reducing excessive exercise, and stopping purging behaviors are the cornerstones of treatment. Treatment plans are tailored to individual needs and may include one or more of the following:

  • Individual, group and / or family psychotherapy .
  • Medical care and monitoring.
  • Nutritional counseling.
  • Medicines.

Psychotherapies

The psychotherapies , such as family therapy where parents of adolescents with anorexia nervosa assume responsibility for feeding their children, seem to be very effective in helping people to gain weight and improve eating habits and mood.

To reduce or eliminate bingeing and purging behaviors, people can undergo cognitive behavioral therapy , which is another type of psychotherapy that helps a person learn how to identify distorted or unhelpful thought patterns and recognize and change inaccurate beliefs.

Medicines

Evidence also suggests that medications such as antidepressants, antipsychotics, or mood stabilizers approved by the US Food and Drug Administration may also be helpful in treating eating disorders and other co-occurring illnesses such as anxiety or depression.

Prevention

Prevention aims to promote healthy development before the onset of eating disorders, it also aims to identify a disorder early before it is too late to treat it. Children between the ages of 5 and 7 know the cultural messages about body image and diet. Prevention comes in by bringing these problems to light.

The following topics can be discussed with young children (as well as teens and young adults).

Emotional eating: Asking children why they might eat in addition to being hungry, talk about more effective ways to deal with emotions, emphasizing the value of sharing feelings with a trusted adult.
Say no to teasing:  Another concept is to emphasize that it is wrong to say hurtful things about other people’s body sizes.
Body Talk:  Emphasizes the importance of listening to your own body, that is, eat when you are hungry (not starve) and stop when you are satisfied (not stuffed). Children intuitively understand these concepts.
Fitness comes in all sizes: Educate children about the genetics of body size and the normal changes that occur in the body, discuss their fears and hopes of growing larger. Focus on fitness and a balanced diet.

The internet and modern technologies provide new opportunities for prevention, online programs have the potential to increase the use of prevention programs. Developing and practicing prevention programs through online sources allows reaching a wide range of people at minimal cost, such an approach can also make prevention programs sustainable.
