Kidney problems can be easy to miss in the early stages. Many people do not feel obvious symptoms until kidney function has already declined. That is why changes in urination, swelling, unusual back or side pain, foamy urine, or blood in the urine should not be ignored.
Your kidneys filter waste from the blood, balance fluids, help control blood pressure, and remove extra water through urine. When they are not working well, warning signs may appear in different parts of the body.
