Hi adezmom! I am a volunteer, not a medical professional, so any information passed on to you should be verified & discussed with your Father's healthcare team.
I checked out a terrific website and found out some information that I believe you will find useful. Please refer to http://www.labtestsonline.org/understanding/analytes/bun/
test.html for some answers to your question.
I, thankfully, do not have any personal experience with this area of diabetes, but hope that others out there who do, will share their knowledge with you.
From the information that you have stated, it looks like you are doing the right thing by inquiring further into what the results mean for your Dad. Have you posed this question to his endocrinologist? Has he been maintaining better control of his blood sugars? It can be challenging, but better bg's mean better overall health. If you need help with that, please let us know and good luck with your Dad!
My doctor advised me to take a 24 hour urine analysis after he performed the blood tests on me testing all kinds of different things such as glucose levels, thyroid, etc. Should I be concerned or is this standard and common procedure for testing of Diabetes?
please read the web page
This has an article on a person who was on dialysis and is now leading a normal life. Modern medical treatment hits a dead end with a case as of your father. Maybe you can try this also while continuing your normal regular treatment with the endocrinologist/nephrologists.
If possible encorage him to start yoga and meditaton. Though yoga has its roots in India , but it is now practised the world over.
