This document discusses hernias, hernia repair surgery, and the relationship between body mass index (BMI) and surgical outcomes. It notes that higher BMI is associated with greater risks of wound complications and hernia recurrence after repair surgery. Specifically, it states that patients with a BMI between 30-40 have 3 times greater risk of wound problems, and those over 40 have 6 times greater risk. It also recommends patients aim for a BMI as close to 30 as possible for the best chance of a successful surgery. The document provides resources for weight management and weight loss surgery.
