Hello there, First of all congratulations on the kidney transplant. You are one of the very few lucky ones who get a transplant in time. The medications you are on now are to prevent your body from rejecting the transplant which is a foreign body in your body. They do have a few side effects like all other drugs and one of them is high blood sugars. This is a type of diabetes called NODAT(New onset diabetes after transplant). Usually you need to be on some treatment for the high sugars depending on your sugar levels and kidney functions. You need to visit a diabetologist who can evaluate you and suggest some blood tests like Fasting blood sugars and post meal blood sugars and average sugar i.e HbA1c. After seeing the values your diabetologist can guide you whether you can be on oral medicines or need some insulin. If you continue to have high blood sugars it can damage your other organs along with your new kidney. So controlling sugars is important. Also the medications for kidney transplant cannot be stopped for some small side effects. If they are stopped it will put you at high risk for rejection. So try to see the bright side of the picture and keep track of your sugars and visit a diabetologist. Hope this helps. Take care.
