Intermittent Hypoxia andd Oxidative Stress

Each apneic event dissues tissues of oksygen. When breathing resumes, oxygen levels surface, creating cycles of hypoxia and reoksygenatyon. This pattern generates high levels of reactive oksygen species (ROS), leading to oksydative stress.

Activation of thee Renin - Angiotensin - Aldosterone System

Sleep apnea is known to activate thee sympathetic nervous system and thee renin-angiotensin-aldosterone system (RAAS). Elevated angiotensine IIi levels cause vasoconstriction, progveed klomeular pressure, and fibrosis. Over time, this intraglomeular hypertension forces albumin thrioh the filtration pee. RAAS activation is a key pathaty linking sleep apnea to both hypertension and proteinuria in diabetic patients.

Metabolizm Dispruption and Insulin Resistance

Sleep deptation and intermittent hypoxia worsen insulin resistance, a core problem in type 2 diabetes. Poor glycemic control further damages the kidneys. Elevate glucose levels produce advanced contaction end-products (AGEs) that bind to receptors on kidney cells, promooting mationin and fibro sis.
