DSM IV
(8) Somatiform Disorders. People with these disorders have a lot of physical symptoms, like pain or stomach problems. However, these symptoms are not thought to be caused by an actual medical disorder. They are thought to be caused by mental health problems instead. One example is hypochondriasis, where a person is always worried that they have serious medical problems when they do not. Another condition in this category is Body Dysmorphic Disorder, where a person hates his body, or a part of his body.
