Hi Gizmos Mom,
I am not a doctor but I was diagnosed with CKD in 2006. Through diet (and blood pressure meds) I've been able to keep my GFR between 45-50 since then. I know how scared you must be but don't panic. Know that while CKD can't be cured it can many times be controlled for many years, perhaps forever. At 51 (which may vary a little either way once you are on meds or through diet) you are at the higher end of Stage 3. Your glucose is a little high so you need to check that as you may be diabetic or pre diabetic. Your creatinine isn't that bad - mine's been that since 2005. Check with your doctor when he gets back from his holiday. In the meantime you might check out this website www.DaVita.com. It has loads of information and it helped me immensely when I was first diagnosed and there was little information available where I live. It's important that you realize that there are things you can do for yourself which is mainly diet - for CKD you'll need to keep your protein low to perhaps 60 -70 grams (total) a day. You'll need to have blood tests for potassium and phosphorus to see if you will need to make any adjustments in the amount of fruit and veggies you eat a day. If you are diabetic then either medication or, again, controlled diet. Too, know that many over the counter meds affect your kidneys - so use sparingly, if at all. Consider your blood tests - which I get every 3-4 months - to be your bible. They will show you how you are doing in controlling your diet so insist on having them at least twice a year if not more often. Another good website is www.livestrong.com where you can input what you eat each day and it tallies up many of your nutrients - protein, fat, carbs, etc. I know it seems like a lot but just learn at your own pace and write down questions to ask your doctor when you get back - he should refer you to a nephrologist (insist on that) who is specialized in CKD. Don't let all the information initially overwhelm you - DaVita will help educate you and they also have a daily menu planner that might help you get started understanding how to control your diet.
I wish you the best, know the odds are on your side for a long and normal life.
