Sleep apnea is a common yet of ten undedicsed disorder charakteristized by repeted intermitions in breathing during sleep.

Co je to Proteinuria?

Proteinuria refers to te te abnormal presence of protein in thoe urine. Healthy kidneys filter waste products from th te blood while retaing essential proteins like albumin.

Te connection bebeen sleep apnea and proteinuria is not contraidental.

Intermittent Hypoxia and Oxidative Stress

Each apneic event deraves tissues of oxygen. When breathing reconcepmes, oxygen levels regery, creating cycles of hypoxia and reoxygenation.

RAAS action is a key patway linking sleep apnea to both hypertension and proteinuria in divetic patients.

Metabolic Disruption and Insulin Resistance

Sleep deprivation and intermitent hypoxia worsen insulin resistance, a core problem in type 2 diabetes. Poor glycemic control further damages the kidneys. Elevate glucose levels produce advance d Amention end- products (AGEs) that bind to receptors on kidney cells, promoting concenmation and fibrossis.
