Psychosomatic illnesses represent a complex interaction between mind and body, wherein psychological factors contribute significantly to the onset, severity, or maintenance of physical symptoms. These illnesses are not merely imagined or fabricated; rather, they involve real physiological changes or distress that cannot be fully explained by a medical condition alone. The term “psychosomatic” underscores the inseparable link between psychological processes and somatic manifestations, highlighting the importance of understanding both emotional and biological contributions to health and well-being. In modern clinical psychology and psychiatry, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides a structured framework for understanding a range of conditions that fall under the category of somatic symptom and related disorders.
