I'm wanting to have a tummy tuck and breast augmentation - I'm a type 2 diabetic.

Thanks for your question.
I agree with much of what has already been posted in response.  There is not an absolute A1C "cutoff" for surgery.  It is best used as one piece of the puzzle in determining your health and risk for surgery.  If you are otherwise healthy, a non-smoker, exercise regularly you should have a minimal increase in your risk.  That being said, an A1C below 7 as been shown to reduce infection and wound healing problems.  Be sure to consult with your physician to try and optimize your glycemic control prior to any surgery.
Best wishes.

Thank you for the question.
 
Well controlled diabetes is not a contraindication to tummy tuck surgery and/or other elective plastic surgical procedures.  However, diabetics are at a greater risk of infection compared to non-diabetic patients. Always best to check with your primary care physician or endocrinologist for “medical clearance” prior to surgery. Managing your diabetic medications around the time of surgery (to avoid hypo as well as hyperglycemia), while you will have altered oral intake, will be important. I hope this  helps.  Best wishes.
