Your kidneys help filter waste, balance fluids, and support many important functions in the body. One of the tricky things about kidney disease is that it often causes no symptoms in the early stages, which is why many people only find out through blood or urine testing. When symptoms do appear, they are usually more noticeable as kidney function gets worse.
1. Feeling tired or weak
When the kidneys are not working well, waste products can build up in the blood. Kidney disease can also contribute to anemia, which may leave you feeling weak, drained, or low on energy.
2. Swelling in the ankles, feet, hands, or around the eyes
Damaged kidneys may have trouble removing extra fluid and sodium, which can lead to swelling. This may show up in the ankles, feet, hands, or as puffiness around the eyes, especially later in the disease course.
3. Changes in how often you urinate
A noticeable change in urination can be a warning sign. Some people need to pee more often, especially at night, while others may notice they are urinating less than usual.
4. Foamy urine
Foamy urine can happen when protein leaks into the urine, which may be a sign of kidney damage. It is one of the classic warning signs listed by kidney health organizations.
5. Blood in the urine
Seeing blood in your urine should never be ignored. It can happen with kidney disease, but it can also be caused by other problems, so it is something that needs medical evaluation.
