Chronic Kidney Disease (CKD)

Chronic Kidney Disease (CKD) is a progressive condition in which the kidneys gradually lose their ability to filter waste and excess fluids from the blood over a period of months or years. The kidneys are vital organs responsible for maintaining fluid balance, electrolyte homeostasis, blood pressure regulation, and red blood cell production. When kidney function declines to below 60% of normal for three months or more, a diagnosis of CKD is established. CKD affects approximately 10-15% of the global population and is a leading cause of morbidity and mortality worldwide. The progression of CKD is classified into five stages based on the Glomerular Filtration Rate (GFR), which measures how well the kidneys filter waste. Stage 1 involves normal or high GFR with evidence of kidney damage, while Stage 5, also known as end-stage renal disease (ESRD), occurs when GFR falls below 15 mL/min, necessitating dialysis or kidney transplantation. The most common causes of CKD include diabetes mellitus, hypertension, and glomerulonephritis. Early detection through routine blood and urine tests is crucial, as CKD is often asymptomatic in its initial stages. Living with CKD requires a multidisciplinary approach involving nephrologists, dietitians, and primary care physicians. With proper management, many patients can slow the progression of the disease and maintain a good quality of life for years. Treatment strategies focus on controlling underlying conditions, managing symptoms such as fluid retention and electrolyte imbalances, and preparing for renal replacement therapy when necessary. Regular monitoring, lifestyle modifications, and adherence to prescribed medications are essential for optimal outcomes in CKD patients.
