Chronic Kidney Disease (CKD) & End-Stage Renal Disease (ESRD)

Chronic Kidney Disease (CKD) refers to the progressive and irreversible deterioration of kidney function over time. The kidneys gradually lose their ability to filter waste products, regulate electrolytes, and maintain fluid balance. Common causes include diabetes, hypertension, glomerulonephritis, and polycystic kidney disease. Early stages of CKD often remain asymptomatic, but as the condition advances, patients may experience fatigue, swelling, nausea, decreased urine output, and high blood pressure.

CKD is classified into five stages based on the glomerular filtration rate (GFR), ranging from mild damage (Stage 1) to severe impairment (Stage 5). Stage 5, known as End-Stage Renal Disease (ESRD), signifies near-complete kidney failure, where the kidneys can no longer sustain life without medical intervention. At this stage, renal replacement therapies such as dialysis or kidney transplantation become essential.

Timely diagnosis through routine blood and urine tests, along with effective management of underlying conditions, can slow the progression of CKD. Lifestyle changes like a kidney-friendly diet, blood pressure control, and avoiding nephrotoxic drugs play a crucial role. Early detection and comprehensive care are vital to improve quality of life and delay the onset of ESRD.
