Tight control. Breast augmentation is a safe procedure as long as your diabetes is well controlled. Diabetics usually have their glycosylated hemoglobin (hba1c) level checked every 3 months. My cutoff is 7. If you're hba1c is under 7, it means your glucose is well controlled and your level of risk with breast augmentation should be the same as that of a non-diabetic.
SAFE w preparation. The risk of surgery is no greater for breast implants in diabetic individuals as any other procedure in a diabetic patient. The same concerns such as wound healing or infection are present and should be addressed. Tight control of the diabetes as well as close peri-operative monitoring of blood sugars with management guided by your physicians, surgeons, and anesthesiologist are advised.
Long term. No difference in long term complications. Immediate risks include infection and difficulty healing if diabetes is not under control, but after everything is healed, you should be fine. http://www.dassmd.com/breast-augmentation/index.html.
Take vitamin pyridox. Since diabetics have elevated cortisol receptors, leading to Insulin resistance, (elevated sugar), and compromised immunity from the cortisone effect, treatment with vitamin b-6, b-2 in the active forms which over time will suppress the cortisol effect, helping healing, reducing infection risk, with sugar control before surgery. Papers on p-5-p, r-5-p, and cortisol receptors, can be found.
