This is true to all patients with type 1 diabetes and partially true to certain people with type 2 diabetes. For patients with type 1 diabetes, the body does not produce insulin and so will need     more

Question: 
I'm 82yrs having carotid artery surgery blockage 90%. surgan wants metforman stopped why?
Answer: 
Metformin should not be used around the time of surgery.  This is a common practice and it can be restarted after the surgical procedure. Another concern might be your kidney function.  There is a certain cutoff for kidney function below which the use of metformin is not safe. It could lead to lactic acidosis, a condition that is dangerous for your health.  You should discuss this issue further with your doctor to see if metformin is still right for you.
