Body checking is a compulsive behaviour related but not exclusive to various forms of body dysmorphic disorders. It involves frequently collecting various information about one's own body in terms of size, shape, appearance or weight.[citation needed] Frequent expressions of this form of behaviour entails for example mirror checking, trying to feel one's own bones, pinching the abdomen, frequent body weight measurement and comparing one's own body to that of others.[1] Studies have shown that an increased rate of body checking correlates with an overall increased dissatisfaction with the own body.[2]
