Individuals with eating disorders have extreme concerns about their body shape and weight, because of which they alter their eating patterns (less or more) resulting in disturbed mind-body functioning, ultimately impacting a person’s physical and psychological health. There is a common belief that eating disorders are a lifestyle choice; in reality they are actually serious and often fatal illnesses, which if left untreated, can cause severe disturbances to a person’s eating behaviors. As mentioned, obsessions with food, body weight, and shape may also signal an eating disorder. 
There are certain behaviors that characterize feeding and eating disorders, such as:
A person suffering from Anorexia consumes little or no food, becomes overwhelmed with the thought of being ‘fat’, and tries to keep their weight as low as possible; for example, by starving themselves or exercising excessively.
Bulimia occurs when an individual goes through periods of binge eating and then deliberately makes themselves sick or uses laxatives (medication to help empty the bowels) to try to control their weight.
It is when an individual feels compelled to over eat huge amounts of food in a short span of time which is followed by feelings of guilt and embarrassment. However, this disorder is not followed by purging behaviors.
The habit of eating dirt or any other item not considered as edible.
This involves behaviors of regurgitating food which continues for a period of 1 month.
The habit of eating a minimal amount of food during the day which results in malnourishment.
