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.
6. Dry or itchy skin
Persistent dry or itchy skin can be linked to kidney problems, especially when kidney disease becomes more advanced. This may happen alongside other symptoms rather than on its own.
7. Nausea, poor appetite, or weight loss
As kidney function declines, some people develop nausea, reduced appetite, or unplanned weight loss. These symptoms are more common in advanced kidney disease and should not be brushed off if they persist.
