• Nephrology
  Colorado Kidney Care encourages you to learn as much as you can about the various aspects of nephrology (the practice of caring for the kidneys) so you can be your own powerful healthcare advocate.
• Kidney Stones
  Nephrology is the medical specialty that deals with kidney disease. A Nephrologist is a doctor who cares for patients with kidney disease. You have two kidneys that are designed to perform complex jobs within your body, like removing toxins from your body as well as control the body’s balance of fluids, electrolytes, and blood pressure. Kidneys are also integral to maintaining bone health because they control vitamin D metabolism and calcium balance. Additionally, they are essential to the production of red blood cells by the bone marrow through the production of the hormone erythropoietin. Unfortunately, many diseases can affect the kidneys and cause problems for the rest of the body. Diseases that harm the kidneys include diabetes, lupus, and cardiovascular disease. As Nephrologists, we care for patients with all types of kidney disease. We also specialize in correction of electrolyte abnormalities, difficult-to-control hypertension, kidney stone prevention, and more.
