Chronic renal failure is a gradual loss of kidney function over time that cannot be reversed. It affects approximately 290,000 people in the United States. The kidneys gradually lose their ability to filter waste and excess fluid from the blood. Chronic renal failure is caused by conditions like hypertension, diabetes, kidney infections, and can lead to complications that affect many organ systems if not managed properly through treatments like dialysis and kidney transplantation. Proper management includes monitoring fluid and electrolytes, reducing metabolic rate, preventing infections, and providing nutritional therapy and skin care.
