HI Thank for asking to HCM I really appreciate your concern the serum creatinine level that you have shown here of course increased, the underlying cause of this is important and that should be treated here you have to get done the test of Renal functions test, with ultrasonography test, here the renal pathology will be detected that might be responsible for increased creatinine value, chewing tobacco might be the reason and that need to be stop, hope this information helps you, have nice day.
