I am female, 66 yrs. and have been taking Lamictal, Lithium, and Emsam for several years - lithium and Lamictal for 12 years. I have High blood pressure (Micardis), pre-diabetes as told by a Dr. a few years ago, and mildly raised cholesterol. I have regular Dr. visits and comprehensive blood panels on a regular basis. Last week my psyche called to say that a creatnine test he ordered just a few days earlier was on the high end. So, I decided to look up and pay more attention to the individual results of 2 recent tests. The last 2 tests were in March 2016 and Dec. 2015. On both tests my creatnine was 1.01-1.02 and GFR 54 and 55. On the line directly below the GFR result on both tests were the words 3rd stage kidney disease. I am completely confused and scared, deciding to halve my lithium, and planning to call my psyche in the morning. Could I really have 3rd stage kidney disease? Healthwise, what do I have to look forward to?
