The impact of psychological stress on glycemic control in type 2 diabetes

Abstract

Diabetes Mellitus type 2 (T2DM) is a significant chronic metabolic syndrome whose global prevalence is growing, and there is a growing body of evidence arguing that psychological stress is critical to its onset and progression. The biological pathways that are triggered by stress include hypothalamic-pituitary-adrenal (HPA) axis, responses of the autonomic nervous system, and persistent inflammation, which are all involved in insulin insensitivity and b-cell dysfunction. Together with these processes, psychosocial determinants such as diabetes-related distress, lack of social support, maladaptive coping and occupational strain contribute to poor self-care and glycemic control. According to recent research, it is possible to achieve positive results when the use of psychological and behavioral interventions in the context of managing diabetes is considered. Evidence-based interventions like Cognitive Behavioral Therapy (CBT), Mindfulness-Based Stress Reduction (MBSR), and structured mental health support have been demonstrated to decrease stress and increase levels of HbA1c, and complementary programs like yoga, relaxation training, mobile health applications, and peer-support programs can be used to increase access and patient response. Collectively, these results demonstrate that a glucose-based model should be replaced with a holistic biopsychosocial model, where stress management is the key to enhanced long-term metabolic stability, adherence to treatment, and quality of life.
