What Causes Elevated BUN And Creatinine Levels?

default
Posted on Mon, 7 Jul 2014
Question: Hi, I'm just wondering is I should be concerned about my BUN and Creatinie readings over the past two routine labs? My primary care didn't note any concern and my endocrinologist just pointed out that these were high and we'd be watching my kidneys readings and maybe do more tests in the future. I asked what caused higher reading...he said an infection can do it. I did have a sinus infection in April...So, I got online to do some reading on this. I also went back to look at the data.
Lab Results:
Creatinine 1.17 Bun 30.0 6/4/2014
1.1 Bun 27.0 4-11-2014
1.24 Bun 34 11/20/2013

Will setting a benchmark standard of quantity of water to drink daily help?
What type of water? Distilled, purified? Thanks.

Brief Answer:
Monitoring is best at this time!!

Detailed Answer:
Hi and thank you so much for this query.

I am so sorry to hear about these not very stellar kidney function tests numbers and all the inconveniences that this has caused you.

I have taken a look at these numbers. They are not ideal but somewhat just over the bar for the normal upper limit. The good news is that these numbers have been stable over the months and implies that it is not an ongoing disease process.

For now, these numbers are not alarming and undergoing further aggressive testing to explore even further may not be the wisest of decisions. It is already good enough that this subtle increase has been picked up and would be monitored to see when more testing and intervention would be needed. There is no reason to be too concerned about this right now.

As for water, drink as much as the body requires. A benchmark of 1.5Litres daily would be a good start and adjusted accordingly based on the daily activities and requirements.

I hope this helps. I wish you well. Thank you so much for using our services and feel free to ask for more information and clarifications if need be.
