How your kidneys work
Your kidneys serve multiple functions for your daily health. The kidneys can filter about 8.3 quarts (or 33 cups) of blood every hour. They take out waste water that turns into urine and heads to the bladder.
They can also help filter out drugs while producing powerful vitamins, like Vitamin D that helps your bones. Kidneys control the production of your red blood cells and release the hormones that regulate your blood pressure.
As we get older, our kidneys naturally begin to deteriorate, but that’s not the only cause of CKD. Though many patients don’t know it because CKD is often asymptomatic, it can often be found in people with diabetes, those who have high blood pressure, are overweight or obscese, have heart disease, or who use tobacco.
