Background It is presumed that breast reduction improves patients' quality of life and promotes weight loss. Preoperative body mass index (BMI) and the amount of breast tissue (breast reduction amount [BRA]) in proportion to the patient's body weight are important variables to affect the breast reduction outcome. Objective This study was designed to evaluate the short and long-term effects of breast reduction from the perspective of BMI and BRA. Methods One hundred fifty-seven consecutive patients were invited to participate in the study. All clinical information was recorded on a breast surgery form. Patients completed a standardized questionnaire preoperatively, at postoperative year 1, and after postoperative year 5. Patients were grouped according to their BMI as "normal weight" and "overweight" and according to BRA as "minor/moderate reductions" and "major reductions." The differences in the BMI values and the life scores were compared between the BMI and BRA groups. Results Sixty-four patients were included in the study. Postoperative year 1 BMIs were significantly lower than both the preoperative BMIs and postoperative year 5+ BMIs. The year 1 BMI decrease in the major reduction group was higher than the decrease in the minor/moderate reduction group. The postoperative life scores of all subgroups were better than the preoperative life scores. Conclusions Reduction mammaplasty has a significant effect on short-term weight loss and the improvement in lifestyle. Patients tend to return to their original body weight in the long term. BRA is a significant variable in short-term weight loss, but neither BMI nor BRA has any other significant effect on the outcome in any time section. Level of Evidence 4.
