In hypochondria paradox, Swedish study finds a higher death rate in those who fear serious illness

A large Swedish study has uncovered a paradox about people diagnosed with an excessive fear of serious illness: They tend to die earlier than people who aren’t hypervigilant about health concerns.

Hypochondriasis, now called illness anxiety disorder, is a rare condition with symptoms that go beyond average health worries. People with the disorder are unable to shake their fears despite normal physical exams and lab tests. Some may change doctors repeatedly. Others may avoid medical care.
