Imagined ill-health, or hypochondria, is a condition characterized by excessive concern about one's health, even in the absence of any real medical problems. Sometimes, people who suffer from hypochondria may experience physical symptoms that they believe to be signs of a serious illness. Synonyms for imagined ill-health include somatization disorder, health anxiety, and illness anxiety disorder. Other possible terms for this condition might include psychosomatic illness, functional somatic syndrome, and non-specific somatic symptoms. Regardless of what it's called, hypochondria can be a distressing and challenging disorder to live with, and it often requires professional treatment in order to be effectively managed.
