Doctors don't know the cause of hypochondria. Maybe the sufferer feels the illness to be deserved due to some past real or imagined wrongdoing; or they want the apparent benefits of being sick, eg receiving attention. Hypochondria may occur to you if you had a childhood illness or had a sibling with a childhood illness. It may be related to another psychiatric disorders, eg anxiety or obsessive-compulsive disorder.
