Common symptoms include persistent anxiety about serious medical conditions, misinterpretation of minor bodily sensations, avoidance of medical appointments, and interference with daily activities due to health preoccupation. The DSM-5 diagnostic criteria require a preoccupation with illness for at least six months, mild or absent somatic symptoms, high anxiety about health, excessive health-related behaviors, and the exclusion of other mental disorders.
