@contentandwell Old habits die hard, I'm a retired nurse so medicalese is familiar to me.

The liver helps process protein and sends it to the kidneys which turn it into urea. BUN stands for Blood Urea Nitrogen, which usually is elevated when the kidneys don't filter as well. It can build up in the bloodstream or come out in urine. Check with your care team but it may be that since your BUN is fairly stable your kidney(s) are putting protein waste products into your urine, which is as it should be - unless there's too much, which can mean your body's not getting/using it. This happens naturally with muscle exercises and weight loss.. I'm not a physician and I'm not diagnosing or prescribing, I'm just stating an opinion based on the little I know.

I agree, if the transplant department thought it was a problem, they'd have you cut back on the protein. It sounds like you're pretty stable.

I'm sending you positive thoughts and wishing you well!
