The relationship of psychiatric illness with gastrointestinal disease.

Higher rates of psychiatric comorbidity as well as more impaired psychosocial adjustment occur with the functional bowel disorders and are particularly high in self-selected referral patients compared with community populations. Reciprocally, some studies show higher rates of functional bowel disturbances in patients with psychiatric diagnoses. Remaining alert for and addressing coexisting psychiatric illness will enhance treatment outcome (increased patient compliance, functioning, and satisfaction). Additionally, psychological factors affect the clinical expression of structural disease. Resetting treatment goals from cure to coping with chronic illness and setting personal limits are important.
