The Influence and Treatment of Sleep Disorders on Diabetes Mellitus

Sleep disorders and diabetes mellitus are both prevalent and increasingly common chronic diseases that significantly impact public health. Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia due to defective insulin secretion or action, leading to multi-system complications. Notably, sleep disordersincluding obstructive sleep apnea (OSA), insomnia, and restless legs syndrome (RLS)are highly prevalent in diabetic populations and often worsen glycemic dysregulation. Sleep disorders impair insulin sensitivity, trigger neuroinflammation and oxidative stress, and disrupt glucose metabolism, thereby worsening insulin resistance and hyperglycemia. Furthermore, alterations in circadian rhythms and reduced sleep quality compromise endocrine and metabolic balance, creating a vicious cycle that hinders effective diabetes control. This article explores the complex and bidirectional relationship between sleep disturbances and diabetes mellitus, emphasizing how disrupted sleep contributes to the development, progression, and poor control of diabetes. It also examines how diabetes-related complications, such as autonomic neuropathy and nocturnal polyuria, further worsen sleep quality. Current treatment strategies, including continuous positive airway pressure (CPAP) therapy for OSA, pharmacological interventions, and behavioral therapies, are discussed. The article highlights the importance of a multidisciplinary approach integrating sleep assessment with diabetes care to enhance clinical outcomes and overall quality of life.
