I always fast on Yom Kippur, but I’m not sure what to do this year. I’ve recently been diagnosed with stage 2 chronic kidney disease. I’m told that it may have been caused by elevated blood calcium which damages the kidneys. I may have to have surgery to remove the parathyroid gland which regulates calcium levels in the body. I know that drinking fluids, and maintaining adequate hydration is important to protect the kidneys and I am concerned about permanent damage I could be causing to my kidneys by not drinking on Yom Kippur. Please advise me what I should do.
Due to your medical condition you should drink “shiuruim”, meaning that you should drink less than 40cc of liquid, and then wait 9 minutes, and then you can drink again, wait nine minutes… This way you will be able to hydrate your body. It is technically possible to drink a liter and a half in this fashion. Since your condition can be life threatening, you are allowed to drink as much as you need to make sure you are not going to be putting yourself in danger. It would be a good thing to find out from a doctor how much you need to drink. You shouold also be careful not to do thinks that will cause you to need more hydration, as you don’t want to cause yourself to have to drink any more than what you need.
May you be blessed with a gmar chasima tova, a good healthy year, to you and your whole family, and have an easy, safe fast.
