I've been Dx'd with mixed connective disease. Recently I got labs done and received the results. My gfr was 53 and albumin, protein, and creatinine all normal, in blood and urine. Also I was Dx'd with diabetes 2 but have not had any problems with it, all A1c's have been normal for 6 out of 7 years since the Dx. I've not taken oral meds nor use insulin at all. My question is could my auto immune disease be causing the Gfr to drop. I'm really perplexed about it. I'm going to see my Dr. in a few days and I thought I'd try to get some kind of answer before then. By the way, I'm 70 yo and am wondering if this could be the culprit.
