Kidney failure occurs when the kidneys are no longer able to filter waste, maintain fluid balance, or regulate essential minerals in the body. This leads to a buildup of toxins in the blood, swelling, weakness, nausea, shortness of breath, and reduced urine output.
Early evaluation, blood tests, urine tests, and imaging help identify the cause and prevent further damage. Treatment may include medications, fluid management, electrolyte correction, and in severe cases, dialysis support. With timely medical care, lifestyle changes, and proper follow-up, many patients can stabilize kidney function and slow the progression of kidney disease.
