I have a bun/creatinine ratio of 7.5 down from a 9. my creatinine is 1.32. it was a 1.1 two weeks ago. i've been on a self-imposed plant-based diet the last two weeks. my bp is ok at 119/81. can you explain exactly what is going on?

Low ratio: Your low bun to creatinine ratio may be due to low protein content of your diet. Your creatinine is mildly elevated. If you haven't had one already, I recommend that you have a urinalysis with a microscopic examination of the urinary sediment to see if you're losing protein and also a measurement of your serum albumin which is the important protein in your body. ? See a nephrologist as needed
