Kidney damage refers to the impairment of kidney function, which can lead to serious health issues. The kidneys play a crucial role in filtering waste from the blood, regulating blood pressure, and maintaining electrolyte balance. When they are damaged, toxins can build up in the body, leading to symptoms such as fatigue, swelling, and changes in urination. There are various causes of kidney damage, including diabetes, high blood pressure, and certain medications. Early detection and management are essential to prevent further deterioration. Lifestyle changes, medications, and in some cases, dialysis or transplantation may be necessary to manage kidney health effectively.
