I've noticed that my creatinine level increased to 1.2 recently, while it had been stable at 0.78 for the past two years. Everything else in my blood and urine tests, including urea, came back normal. The one big change in my life is that I started a rigorous workout and muscle-building routine last year, but Im a vegetarian and dont use any supplements. Im not experiencing any other symptoms. Could the rise in creatinine be due to my exercise routine? Should I be worried about this?

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.
