Therapeutic CPAP does not significantly improve glycaemic control (HbA1c) or insulin resistance (measured by euglycaemic clamp and HOMA) in men with established type 2 diabetes and obstructive sleep apnoea.

If you have type 2 diabetes and sleep apnoea, using CPAP will help you feel less sleepy and improve your quality of life, but it will not lower your blood sugar or fix insulin resistance on its own. You still need to manage your diabetes with diet, medication, or other treatments specifically designed for metabolic control.

Why this rating

The study is a double-blind, randomized controlled trial with a placebo control group, which is the gold standard for establishing causality and ruling out confounders.
