hypochondriasis

Preoccupation with the details of one's bodily functions and excessive concern about the possibility of having a disease. It is generally believed to be caused by neurotic anxiety. Hypochondriacal individuals typically present physical symptoms but no actual disturbance in bodily function. These people often develop physical symptoms such as dizziness, sweating, and rapid pulse, arising from fears about their health. They often seek help from various medical specialists but are reluctant to accept reassurance of well-being. See also neurosis and somatoform disorders.
