- We all want to be liked and validated by other people. The sense of belonging is strong in childhood and adolescence. We want to be part of a group and we do all the things that may help us to be liked by others which may be unhealthy for us.

- There is a set standard of beauty. Being pretty means being slim and fair. So, we get obsessed with the idea of looking slim. We want to fit in it and it leads to the development of body dysmorphia.

- Perfectionism is another factor in developing an eating disorder. Since one wants everything perfect and so there should not be an inch extra of fat.

- Food is something we can control easily, whether we want to binge eat or not eat at all. It gives us a sense of control.

- Constant bullying is another factor that makes us feel unaccepted. We try too hard to feel accepted. Moreover, bullying is a traumatic event and affects us on many levels.

- Symptomatic treatment: Correction of electrolyte imbalance by providing supplements. Providing fluid therapy to reduce dehydration. The client may require the insertion of a nasogastric tube in order to maintain nutritional balance. Constant monitoring of weight to assess progress.

- Medications: Antidepressants, Selective serotonin reuptake inhibitors (SSRI) MAOIs to treat depression and OCD. Anti-emetics are used to prevent the client from purging.

Olanzapine is used to stimulate appetite.

- Therapies include CBT which is Cognitive behavior therapy and family therapy.
