Hey doctor, I recently got my blood tests done, and my creatinine level came back at 1.2. It was 0.78 for the past two years. Everything else, including urea, was normal. Last year, I started working out more intensely and focusing on muscle building, but I dont take any supplements and follow a vegetarian diet. I dont have any other symptoms either. Is this increase in creatinine something I should be worried about? Can intense exercise cause creatinine levels to rise like this in just a year?

The increase in creatinine levels from 0.78 to 1.2 over a year can be attributed to your rigorous workout regime and muscle building. When muscle tissue is broken down during exercise, creatinine is produced as a byproduct. Since you are vegetarian and do not take supplements, the increase in creatinine levels can be considered a normal response to your increased muscle mass. However, it is important to continue monitoring your creatinine levels and consult with your healthcare provider for further evaluation if needed.
