Implant-Based Breast Reconstruction: Impact of Body Mass Index on Postoperative Complications and Aesthetic Results: A 5-Year, Single-Center Study.

Background: Increasing adoption of implant-based breast reconstruction (IBR) has raised expectations regarding postoperative outcomes and aesthetic results. BMI has been extensively explored as a predictor of complications. This study is the first to examine complication rates in underweight subjects, and compares these rates among underweight, normal weight, overweight, and obese patients.
