3. Persistent Fatigue and Muscle Weakness
Healthy kidneys manufacture a specific hormone called erythropoietin, frequently referred to as EPO. This vital hormone instructs your bone marrow to produce oxygen-carrying red blood cells.
When your kidneys struggle or sustain damage, their EPO production drops significantly. This rapid decline leads to a lower red blood cell count, a medical condition known as anemia. Anemia physically starves your brain and muscles of the oxygen they require to function.
Without adequate oxygen delivery, you will experience a profound, inescapable sense of exhaustion. You might feel unusually cold even in a warm room, or you might experience sudden dizziness when standing up—a major fall hazard for older adults.
If your usual morning walk or routine household chores suddenly leave you feeling completely drained and physically weak, you must not simply write it off as just getting older. Persistent fatigue requires a thorough medical investigation.
