Diabetics with renal failure can experience unexpected hypoglycemia because the kidneys are involved in the metabolism of insulin. When the kidneys decline in function or fail, the metabolism of insulin is slowed and so it continues to operate for a longer time in the body, thus becoming more effective in reducing blood sugar. But on the other hand, dialysis causes a continual state of hormonal chaos, and as every diabetic patient knows, unstable hormones during the teenage years can cause both high and low blood sugar spikes, so again, the blood sugar becomes more difficult to control.The overriding consideration for diabetics with renal failure is that for them, getting a transplant and getting off dialysis as rapidly as possible is medically much more important than it is for other patients. Diabetics have a very much lower life expectancy on dialysis than others do, and their complications are made worse by the fact that excess sugar remains sequestered in the blood much longer than in patients with normal renal clearance, since the kidneys normally serve as a 'second pancreas' by removing excess sugar from the blood. While a transplant doubles the life expectancy of the average dialysis patient (depending on age, of course), it triples the life expectancy of a diabetic dialysis patient. Diabetics on PD also have the problem that the dialysate is based on glucose, which elevates both blood sugar levels and blood lipid levels.Interestingly, there is increasing evidence that diabetic renal failure is not caused by high blood sugar levels. The fact that there is an extremely sharp peak of new cases of diabetic renal failure 17.5 years after onset of diabetes, despite the fact that there is a fairly flat Bell curve distribution of excess blood glucose levels in that population, suggests that something else, quite possibly some gene inherited along with the genes for diabetes, is causing renal failure. The astonishing fact that very few diabetics who do not develop renal failure within 20 years of diabetes onset ever go on to develop it later, however high their blood sugar is for however many more decades they live, strongly points to something other than high blood sugar causing diabetic renal disease. The recent research by P. Aaltonen, et al, "Antibodies to Nephrin in Patients with Diabetic Nephropathy," Nephrology, Dialysis, Transplantation (2007) 22 (1) 146-153, suggests that the real culprit in diabetic renal failure may be the continuing autoimmune attack on the body which first began years before with the attack on the beta cells of the pancreas.
Stauffenberg is one of our resident experts. I have learned more from some of our members than I have from any doctor. Hope you find an answer to your question.
Hey Folks,I have Diabetes and Kidney Failure. Since my Kidney's have shut down I am having a very difficult time managing my bloodsugars. I wear an insulin pump and I have changed my carb to insulin ratio and my insulin sensitivity but I am still having problems. My sugars were never that great but much better than they are now. What is everyone doing for this? Am I alone in this or do others have similar problems?MODS: I would have put this in the diabetes section but there is not much action there.MarkModified: some dumb a$$ cannot spell
Chris,I hear you on the pump problems. They are a big advance but not perfect. I have plenty of mechanical problems with the pump also. I can handle that alright. My concern is getting the basels set correctly.Mark
