Weight stigma mitigating approaches to gender-affirming genital surgery

Abstract

The use of body mass index (BMI) to determine eligibility for gender-affirming surgery in transgender and nonbinary individuals has been contested. While BMI thresholds are often meant to be protective, restricting patients from access to surgery can also cause harm. There is a rationale for the continued use of BMI, but the inherent problems with it must also be recognized, including how weight stigma impacts patients’ access to gender-affirming surgery and influences clinical care. This article uses a narrative review of current literature to discuss how high BMI affects surgical outcomes in gender-affirming genital surgeries, as well as analogous procedures, existing de facto BMI thresholds, and how to both minimize the harms of proceeding with surgery in patients with a high BMI or the harms of delaying for weight loss. BMI factors into surgical decision-making based on the existing literature, which demonstrates that high BMI is associated with increased surgical risk, including higher incidences of surgical site infections and poor wound healing, as well as the possibility of free flap complications, which are a component of certain genital procedures. This patient population is at higher risk for eating disorders, and it is prudent to find alternatives to requiring patient self-monitored weight management. The impacts of weight stigma should be considered when treating gender-affirming surgery patients, and further data and research are needed to augment shared decision-making and lead to practice change.
