Best Doctor List Near You for Renal Failure in Porto alegre

Renal failure, also known as kidney failure, is a medical condition characterized by the kidneys' inability to adequately filter waste products and excess fluids from the blood, leading to a buildup of toxins in the body. There are two primary types of renal failure: acute renal failure (ARF), which occurs suddenly and can be reversible, and chronic renal failure (CRF), which develops gradually and is often progressive. Both types can significantly impact overall health and require timely medical intervention. The causes of renal failure are varied. Acute renal failure can result from conditions such as severe dehydration, acute infections, or exposure to nephrotoxic drugs or toxins. It can also arise from sudden obstructions in the urinary tract, such as kidney stones or tumors. Chronic renal failure is often caused by long-term conditions like diabetes, hypertension, or glomerulonephritis, which damage the kidneys over time. Genetic disorders, such as polycystic kidney disease, and prolonged use of certain medications can also contribute to chronic renal failure. Complications associated with renal failure can be severe. In acute renal failure, complications may include electrolyte imbalances, fluid overload, and potential progression to chronic renal failure if not treated promptly. Chronic renal failure can lead to end-stage renal disease (ESRD), requiring dialysis or kidney transplantation to sustain life. Other complications include cardiovascular issues, anemia, bone mineral disorders, and weakened immune function. Managing renal failure involves regular monitoring of kidney function, treatment of underlying conditions, and supportive care to manage symptoms and prevent further progression.
