Hello all-
This is more out of curiosity at this point rather than concern...I had labs done for an annual physical and I go see the Dr. on Tuesday to review. I saw the labs were posted today so I went through them in order to prepare what to talk to her about. I saw that my BUN/Creatinine ratio was 9 which on these labs is the lowest number of the normal range so it will not pop up out of range and my guess is she will not even mention it. I noticed it though. In Feb last year the ratio was 13 and in Sept last year at my GI it was 12 and now 9. When I look at the BUN number it was 11, then 12 and now 8 (normal range 6-24) over those same labs and the Creatinine has slowly crept up from .82 to .88 to .91 now-this lab places high of range at 1.0. I'm thinking this number going up could be related to high protein diet....
Just curious if there are any thoughts especially on the BUN lowering so much in the last 5 months?? Everything I see is related to the BUN increasing and being an issue and that the lowering is not a big concern unless other factors are present. My liver enzymes are great. Nothing in urine-all negative. Not on any drugs other than Armour and taking supplements that many others here are-D, B complex,magnesium
Otherwise all looked pretty good.
As for as MC stuff-I feel like in the last week I can feel my gut slowing down if that makes sense. I definitely have had fast transit issues probably most of my life. When I had the barium follow though last year a month before my dx with LC, I pretty much set a record there. Went through me very fast and the Dr there said they are usually on the lookout for slow but my GI called to talk about results and was like-you defiantly have fast transit issues. Maybe my diet changes are finally kicking in-and in the last 2 weeks I have tweaked diet more based on Enterolab results.
Appreciate you all reading and if anyone has ideas on the blood work, I'd love to hear. Thanks!

Hi Taia,
Compared with your past results, your current test results may have been skewed for some reason or other. Sometimes test results are incorrect for various unknown reasons.
If the numbers are accurate, a BUN/Creatinine ratio may be decreased because of liver disease (due to decrease in the formation of urea), but if that were the case then your liver enzymes should have been elevated. Another possible cause is malnutrition. It can also be caused by being overhydrated when the blood draw was made.
Low BUN levels are not common and are not usually a cause for concern. They may be seen in severe liver disease, malnutrition, and sometimes when a person is overhydrated.
It's true that increased protein in the diet can cause an increase in creatinine. But creatinine levels can also be increased due to kidney disease, or other issues that affect kidney function. For example, a magnesium deficiency can affect kidney function. When I had the magnesium deficiency problem last spring, my creatinine level was significantly above range, but it came down quickly when I increased my magnesium intake
If your Estimated Glomerular Filtration Rate (GFR) was within the normal range, then your kidneys are probably OK. My GFR was way below range when I had the magnesium deficiency episode.
Your current test results are probably transient, and nothing to be concerned about. And after all, they are within the normal ranges. If that trend continues with the next set of test results, then there might be a reason to do a little more testing.

It is suspected that some of the hardest material known to science can be found in the skulls of GI specialists who insist that diet has nothing to do with the treatment of microscopic colitis.
Thanks Tex! You confirmed what I had researched. My GFR was 75 and the reference range was above 59 so that looks good.
One thing I wondered about with blood sugar...I see my HA1-C is 5.3 but fasting glucose was 103 so that is a bit high. Seems odd. Again, maybe a fluke. I saw eating low carb can cause fasting glucose to be higher. It usually hovers at 89-91 but last year at this time was 98 with A1-C 5.4. She didnt seem concerned. I would think with a restricted diet this would be lower. I don't use a lot of gf alternative flours and have cut potatoes and rice way down in the last few weeks. Comments or non issue for now?
I think I will up the external magnesium a bit-although from reading your recent post on mag., that may be easier said than done!!
