9. Shortness of Breath
When kidneys fail, fluid can accumulate in the lungs—a condition called pulmonary edema. Additionally, anemia reduces oxygen delivery to tissues. Both can cause:
- Difficulty breathing, especially lying down
- Chest tightness
- Fatigue after minimal exertion
Shortness of breath should never be dismissed, particularly if accompanied by swelling or other signs of kidney trouble.
10. Nausea, Vomiting, and Gastrointestinal Issues
Waste accumulation in the blood affects the digestive system, leading to:
- Persistent nausea
- Vomiting without obvious cause
- Loss of appetite
- Unexplained weight loss
These symptoms, especially when chronic, are common in advanced kidney disease.
11. Poor Concentration and Brain Fog
When toxins build up in the blood, they can impact brain function, leading to cognitive issues such as:
- Confusion
- Poor memory
- Difficulty focusing
- Dizziness
This is often accompanied by fatigue and should not be confused with typical forgetfulness or aging.
