Kidney failure, or renal failure, is a critical condition where the kidneys lose their ability to effectively filter waste from the blood. This failure can lead to the buildup of toxins and fluids, causing significant health issues. Recognizing the early signs, such as fatigue, swelling, and changes in urination, is essential for timely intervention. Understanding the various causes and risk factors, including diabetes and high blood pressure, can help in prevention and management. With a range of treatment options available, including medication, dialysis, and lifestyle changes, managing kidney failure is possible with the right approach and medical guidance.
