Should Diabetics Avoid Tummy Tuck?

I am a 19-year type 1 diabetic. I have not had any problems with my weight management through out the course of my life. I exercise regularly and keep tight control of my diabetes. I check my glucose levels about every two hours through out the day. I am now faced with a bulging mid-section after being pregnant and giving birth to a rather large baby (over 10 lbs). My HA1C test during pregnancy was 5.8. I have consulted with two plastic surgeons about getting a Tummy Tuck, and neither of them had a problem with me being diabetic. However, there was one plastic surgeon's office I contacted first and I was flat out refused. I was told that the surgeon would not even consider doing such a procedure on me because I am diabetic. She also warned that I should be cautious of anyone willing to perform the procedure on me. This news is unfortunate for me, because this doctor seems to be very skilled and have great training, not to mention does great work with belly buttons. I am wondering, is what I was told valid or was the person I spoke with speaking irrationally?
