Well I've hit a problem. After 4 1/2 months of prep work and 1 week from my July 14th surgery date my pre-op blood bloodwork came back with a spike in my BUN level.

The surgeons office has me go retake the test and apparently it got even worse. My surgery is now on hold and I have to see a kidney doc and get an ultrasound.

I was 8 days into my 14 day pre-op diet (bariatric advantage) and was feeling very low energy and weak. Looks like the very high protein diet has messed with my kidney function and my body is reacting Badly to the shakes. Now back on a LOW protein low cal diet until all new doc(s) get to check me out. Anyone run into this? A very depressing day.

That really sucks, I'm so sorry.

Hey @@moltoguy

I had a creatinine spike (kidney function issue) right before surgery. I've also been postponed. How did you fare?
