Kidney problems refer to issues that affect the kidneys, which are vital organs that help filter waste and excess fluids from the blood. When the kidneys don't function properly, waste can build up in the body, leading to symptoms like fatigue, swelling, and changes in urination. Common kidney problems include kidney stones, chronic kidney disease, and kidney infections. Many factors can contribute to kidney problems, such as high blood pressure, diabetes, and a poor diet. It's important to maintain a healthy lifestyle, including drinking enough water and eating balanced meals, to support kidney health. Regular check-ups with a doctor can help catch any issues early.
