7. Puffy Eyes
Notice puffiness around your eyes, especially in the morning? This may happen when protein leaks into the urine, signaling possible kidney damage.
8. High Blood Pressure
Kidneys play an important role in regulating blood pressure. When they are not functioning properly, blood pressure may rise, and uncontrolled hypertension further damages kidney health — creating a dangerous cycle.
9. Shortness of Breath
Fluid buildup in the lungs caused by kidney failure can lead to breathing difficulties. Additionally, anemia from kidney disease reduces oxygen supply to the body, leaving you feeling breathless.
10. Metallic Taste in the Mouth
Toxin buildup in the blood may affect taste perception. Many people with kidney problems experience a persistent metallic taste or bad breath, often described as ammonia-like.
11. Loss of Appetite
As waste products accumulate, nausea and poor appetite are common. Over time, this may contribute to unintentional weight loss and nutrient deficiencies.
12. Muscle Cramps
Electrolyte imbalances — particularly with calcium, magnesium, and potassium — may cause painful muscle cramps or spasms. This is another sign your kidneys may not be maintaining proper balance.

13. Difficulty Concentrating
When toxins build up in the blood and anemia reduces oxygen delivery to the brain, concentration and memory may decline. Brain fog or poor focus can be an early sign of kidney issues.
