To improve kidney function, it is important to adopt several healthy lifestyle habits and take care of underlying health conditions. Key measures include staying physically active, managing blood sugar and blood pressure, maintaining a balanced diet low in sodium and processed foods, drinking plenty of fluids, avoiding smoking, and being cautious with over-the-counter pain medications like NSAIDs. Monitoring weight, reducing alcohol intake, and following medical advice for any existing conditions also help protect kidney health and prevent damage. Following these recommendations supports the kidneys in filtering waste and regulating important body functions properly, reducing the risk of chronic kidney disease or further deterioration if kidney issues exist.
