9. Headaches, fatigue, and general weakness
Vitamin D is converted in our bodies by healthy and properly functioning kidneys to maintain strong bones and create a hormone called Erythropoietin (EPO). This hormone is crucial for the formation of red blood cells. When the kidneys aren’t working correctly, they create less EPO. The loss of red blood cells (which carry oxygen) causes the fast weariness of your muscles and brain.
Warning: Anemia is prominent in persons with Chronic Kidney Disease. Anemia may develop when a person’s kidney function is between 20% and 50% of normal. If you’re receiving adequate rest and sleep but still suffering fatigue, low energy levels, and general weakness, you should see your doctor right away.
