Thank you for writing.
I assume by transplant you mean kidney transplant.
The mean creatinine level in transplant patients is 150 µmol/L. How high are your levels?
You are at a very sensitive time - just two weeks post-transplant. A vegetarian diet can help with lowering creatinine in the body but at this junction, you need to speak with your doctors about healthy ways to lower your levels. Your immune system is likely very low right now - you need advice from your medical team.
