If you have chronic kidney disease, your doctor may have told you that your parathyroid glands are a little overactive. This condition is called hyperparathyroidism. You may have been prescribed a medication called Calcifediol as a treatment for this. So today, let's talk about this medication in a very simple and friendly way, what it does to your body, and what you should be careful about when using it.
Simply put, what is Calcifediol?
Calcifediol is a special form of vitamin D. The four parathyroid glands in our neck sometimes become overactive in people with kidney disease. When this happens, a chemical called Parathyroid Hormone (PTH) is produced in our blood in excess. This increased level of PTH is not good for our bones, that is, for bones. Over time, bones can become weak.
So, what this Calcifediol medicine does is control the increased PTH hormone levels . Through this, it helps protect your bone health and keep them strong.
