Te Physiology of Insulin in Kidney Disease

Heathy kidneys degrade and excurte a important portion of circulating insulin.

Te Role of Uremic Toxins in Glucose Dysregulation

Other Medications: Interactions and d Side Effects

Many CKD patients take medications that can influence blood glukose or insulin acidotics. Examples include kortikosteroids (creape glukose), certain diuretics (can cause hypokalemia and alter glukose metabolismus); and erythropetin- stimulating agents (may improne insulin sensitivity). Additionally, some blood pressure medications like beta- blockers can mask hypoglycemia contentoms, and ACE concentriors may insulin sentivity.

Impact of Anemia and Erythropoietin Therapy
