Needing to urinate more often (especially at night) or much less than usual are both warning flags of kidney malfunction.
6. Pain in the Lower Back or Side
Kidney pain is often felt on one side of the back, just under the rib cage. It may signal stones, infection, or advanced kidney disease.
7. Constant Itching
When toxins build up due to poor kidney filtration, they can cause intense itching beneath the skin.
8. Shortness of Breath
Failing kidneys may lead to fluid in the lungs or reduced oxygen-carrying red blood cells, leaving you breathless after minimal activity.
9. Puffy Eyes
Persistent puffiness around the eyes may indicate protein loss through urine, one of the earliest signs of kidney issues.
10. Muscle Cramps
Imbalanced electrolytes like calcium and phosphorus, caused by kidney problems, often lead to painful cramping.
11. Metallic Taste in Mouth
Toxin buildup can give you a constant metallic taste or cause bad breath (uremic breath).
12. Poor Appetite and Nausea
Kidney failure may cause toxins to accumulate, leading to nausea, vomiting, and an overall lack of appetite.
