Sleep disorders in individuals with diabetes mellitus are a significant concern due to their bidirectional relationship, impacting both diabetes management and overall health. Many diabetic patients experience disturbances such as obstructive sleep apnea (OSA), insomnia, restless legs syndrome (RLS), and alterations in sleep architecture. OSA, often prevalent in diabetics, exacerbates insulin resistance and glucose intolerance through intermittent hypoxia and sleep fragmentation. Insomnia, another common issue, can worsen glycemic control and increase the risk of diabetic complications. RLS affects sleep quality and is associated with higher insulin resistance and prevalence in diabetic populations. Moreover, diabetes-related neuropathy can lead to painful sleep disturbances. Addressing these sleep disorders requires a multidisciplinary approach involving endocrinologists, sleep specialists, and neurologists. Treatment may involve lifestyle modifications, continuous positive airway pressure (CPAP) for OSA, medications for RLS and insomnia, and optimizing diabetes management to improve sleep quality and overall health outcomes.
