Types of Bulimia Nervosa
Bulimia is classified into purging type and non-purging type based on the methods adopted by patients for weight loss.
Bulimia has been classified as two types:
- Bulimia of purging type
This type is characterised by the use of self-induced vomiting or excessive usage of laxatives to purge food in order to prevent weight gain. Some patients may use diuretics.
- Bulimia of non-purging type
This type is characterised by using means, other than the self-induced methods, to avoid weight gain, like extreme degrees of fasting or excessive exercising that are both inappropriate.
