@rrr1952 I have stage 3B CKD from norovirus 2 years ago, and IBD (microscoic colitis). I am on Jardiance, an SLGT2 inhibitor even tho I don't have heart disease, diabetes, or high blood pressure (was 120/70, now 105/73). Because of the IBD I don't tolerate NSAIDs, ACE or statin meds, some preservatives, or artificial sweeteners (we went low sugar years ago and don't miss it). So, to make a short story long, I moderate my water intake like @cheyne does because of water loss from IBD. Mostly pescatarian now, we need protein but not as much as the American diet. No beef, limit sodium, potassium, and phosphates. A lot of it is portion control. Hopefully you can find a good renal diatician to help you integrate your CKD and diabetes diets (there must be some out there). Also, exercise is very important to kidney and heart health. I think in the end, the balance is somewhat like a Mediterranean diet, but it should be individualized to your specific health issues.

Hi,
Eggs are good, cheese not so as with CKD you may find it can cause constipation. I use sardines to good effect despite being high in sodium they are high in energy and slow release so ideal for diabetics and my kidneys don't seem to mind. Sadly not to everyones taste though. Switch to wholemeal breads and try to limit the amount you eat. One thing I do eat is shaved ham slices the thickness you can see through, a max of 4 per day, just about every day on wholemeal bread with plastic butter. Chicken and fish are good along with vegitables but not parsnip as they are high in natural sugars. Stay away from fruit juices as they are also high in sugars, you are better to eat the fruit it's self. A medium glass of juice is equivelant to many fruits at once. Eventually you will find out what you can eat and what to steer clear of from testing your bloods and kidney function. I try to get blood drawn at the same time of day after having done the same things as the previous test date. This gives me a constant to judge how I'm doing. I know I can destroy those test results at will, when I feel my Dr's aren't paying attention. It is so simple and gets undivided attention instantly the results are returned. I found I have to use this trick to persued my Dr's to give me what I thought I should have to start with. Find I have to make it their idea to get results, I must be a bastard of a patient to deal with! But we get there in the end.
With what I go through daily it has been the ability to research everything and sift out the facts that helps me deal with it all. If I left it up to my Dr's I would still be getting temporary paralysis and every other symptom I get from Hyperglycemia and the shrug of the shoulders with the exclaimation we don't know what it is. I'm greatful I have been able to diagnose the problem and prove it with the results of treatment before the paralysis had a chance to become permanent.
While we are all humans we can react or operate in very different ways to any given food or medication. My rule of thumb is to research before taking the next medication that is going to cure me, because they haven't so far. While I think of it stay away from Gabapentin it will knobble your kidneys, I loose 15 percent in days but only get it back after weeks of strict diet. I find like me Dr's don't know everything, big problem is I'm their test case and they seldom get it right at the expence of my health.
Cheers
