Chronic Renal Failure, also known as Chronic Kidney Disease (CKD), is a gradual loss of kidney function over time. The kidneys are essential organs that filter waste and excess fluids from the blood. When they fail to work properly, harmful substances can build up in the body, leading to various health issues. This condition can result from several factors, including diabetes, high blood pressure, and glomerulonephritis. Symptoms may not appear until the disease is advanced, making regular check-ups important for early detection. Treatment options include lifestyle changes, medications, and in severe cases, dialysis or kidney transplantation.
