Kidney issues refer to problems that affect the kidneys, which are vital organs responsible for filtering waste and excess fluids from the blood. Common conditions include chronic kidney disease, kidney stones, and acute kidney injury. These issues can lead to a buildup of toxins in the body, affecting overall health. Symptoms of kidney issues may include fatigue, swelling in the legs or ankles, changes in urine output, and high blood pressure. Early detection and management are crucial to prevent further complications, making regular check-ups important for those at risk, such as individuals with diabetes or high blood pressure.
