-
Electrolyte Imbalances:
- Hyperkalemia results in increased potassium levels, posing a risk for cardiac complications.
- Hyperphosphatemia can cause bone disease due to elevated phosphate levels.
- Metabolic acidosis occurs from reduced acid excretion, which may contribute to bone health issues.
- Anemia: Decreased production of erythropoietin leads to anemia, causing fatigue and pallor in patients.
- Cardiovascular Disease: CKD is associated with higher risks of heart failure, stroke, and hypertension.
- Bone Disease: Altered metabolism of calcium and phosphate results in renal osteodystrophy.
- Malnutrition: Characterized by poor dietary intake and protein-energy wasting as a common issue in CKD patients.
- Infections: Increased risk due to immune dysfunction, especially in patients undergoing dialysis.
- Neuropathy: Peripheral neuropathy may arise from toxin accumulation in the bloodstream.
Interventions for Chronic Kidney Disease
- Dietary Modifications: Recommendations include low protein, sodium, potassium, and phosphorus diets to alleviate strain on the kidneys.
- Fluid Management: Careful monitoring of fluid intake and output is essential to prevent fluid overload.
-
Medication Management:
- Erythropoiesis-stimulating agents can help treat anemia effectively.
- Phosphate binders and antihypertensives are prescribed as necessary for managing complications.
- Dialysis: Options include hemodialysis or peritoneal dialysis, crucial for the removal of waste products.
