Chronic Kidney Disease (CKD) means the kidneys are damaged and cannot filter blood effectively, with Stage 3 indicating moderate loss of function. Symptoms to monitor include fatigue, swelling in hands/feet, changes in urination, and nausea. The primary goal of treatment is to slow progression by managing the underlying cause (like diabetes or high blood pressure) with medication and strict lifestyle changes. Dialysis or a kidney transplant (surgery) becomes necessary when the disease progresses to kidney failure (Stage 5). It is crucial to be under the care of a Nephrologist (Kidney Specialist) at a hospital with a dedicated nephrology and transplant department. The cost of ongoing care and potential dialysis is very high, making health insurance essential. Strict dietary guidance is a cornerstone of management, often involving limiting protein, potassium, phosphorus, and sodium intake, and working with a renal dietitian is highly recommended.
