What was done
This narrative review synthesized epidemiological evidence, biological mechanisms, and therapeutic strategies linking obstructive sleep apnea (OSA), obesity, and disturbed glucose homeostasis.
What was found
The authors describe direct weight-dependent mechanisms (fat excess altering respiratory mechanics) and indirect mechanisms (hyperglycemia, insulin resistance, hyperinsulinemia, leptin resistance, and hormonal dysregulation). Interventions including dietary weight loss, bariatric surgery, anti-obesity or antidiabetic pharmacotherapy, and continuous positive airway pressure (CPAP) are reported to positively influence comorbid metabolic and sleep parameters. The abstract reports no quantitative data or specific numerical effect sizes.
Why it matters
It emphasizes the interconnected pathophysiology of sleep apnea and metabolic disease, underscoring that therapeutic management of one disorder can yield concurrent clinical improvements in the others.
Limits
The paper is a non-systematic narrative review providing no study selection criteria, risk-of-bias assessment, or pooled quantitative results. The abstract provides no primary data, participant numbers, or effect estimates.

- context Insulin resistance is mechanistically linked to sleep apnea by promoting fat deposition in the pharynx and upper airway.
