8. Metallic Taste in the Mouth
Waste accumulation can alter taste sensations.
Foods may taste metallic, bitter, or simply unpleasant.
9. Bad Breath
High levels of waste products may contribute to persistent bad breath that doesn’t improve with brushing.
10. Nausea or Vomiting
As kidney disease progresses, toxins may accumulate in the bloodstream, causing nausea and occasional vomiting.
11. Trouble Concentrating
Reduced oxygen delivery from anemia or toxin buildup may make it difficult to focus or think clearly.
12. Difficulty Sleeping
Many people with chronic kidney disease report:
- Insomnia
- Frequent nighttime awakenings
- Restless sleep
13. Shortness of Breath
Excess fluid can build up in the lungs.
Anemia may also reduce oxygen delivery, making breathing more difficult.
14. High Blood Pressure
High blood pressure can both cause kidney disease and result from declining kidney function.
Managing blood pressure is one of the most important ways to protect kidney health.
15. Persistent Lower Back Pain
Pain near the kidneys—located below the ribs on either side of the spine—may occur with kidney infections, kidney stones, or certain kidney disorders.
