Comorbidity of psychiatric illness and physical illness

Psychiatric illnesses rarely occur in isolation; patients will often present with two or more co-occurring psychiatric illnesses. For instance, a mood disorder is often accompanied by an anxiety disorder, and substance use disorders and trauma often present hand-in-hand. This pattern of co-occurrence includes physical illness as mental and physical health are closely interconnected. For instance, chronic physical illnesses such as cardiovascular disease, diabetes, chronic pain, cancer, and autoimmune disorders often have a significant impact on mental health, while psychiatric illnesses can, in turn, affect the onset, course, and prognosis of physical conditions for example the association of schizophrenia with a substantial burden of physical illness. By understanding these interactions, we can provide more holistic and comprehensive care to individuals with comorbidities.
