Mind in Metabolism - A Comprehensive Literature Review on Diabetes and Its Connections to Obsessive Compulsive Disorder, Schizophrenia, and Bipolar Disorder

Purpose Of Review: The co-occurrence of diabetes and mental illnesses such as bipolar disorder (BD), obsessive-compulsive disorder (OCD), and schizophrenia creates significant barriers for both people with diabetes (PWD) and their healthcare teams. This literature review provides an analysis of the relationship between diabetes and mental illnesses through exploring epidemiology, shared risk factors, and clinical implications. The aim is to enhance the understanding of these complex comorbidities to guide and improve future research and clinical practice.

Recent Findings: Recent research suggests a strong link between mental illness, metabolic syndrome, and diabetes. Studies show that BD has a robust relationship with metabolic disease and the antipsychotic medications used in treatment for many mental illnesses are strongly associated with weight gain and metabolic disease. However, there is limited research exploring the bidirectional relationship that diabetes has with BD, schizophrenia, and OCD. While research exists on the link between diabetes and mental conditions such as depression and anxiety, little research has examined schizophrenia, OCD and BD. The findings noted in this review suggest gaps in treatment options, healthcare services, and social support. While this paper provides a foundation for future progress, advancement in this field will require a collaborative effort from researchers, healthcare professionals, and community outreach programs to effectively close the gaps in care noted in these patient populations.
