Type 1 diabetes does not automatically rule out elective plastic surgery, but it does make preoperative planning more important. Safety depends on how well your blood sugar is controlled, your recent HbA1c, whether you have kidney, heart, circulation, or nerve problems, and the length and type of procedure. For larger operations such as BBL or liposuction, I would want clearance from your endocrinologist or primary doctor, a clear insulin plan for the day of surgery, and surgery in an accredited facility with an anesthesia team comfortable managing diabetes. Poorly controlled glucose increases the risk of infection, delayed wound healing, and other complications, so surgery should usually be delayed until your diabetes is stable and optimized.
