What is body mass index (BMI) and why is it important?
Body mass index is a measure that correlates height and weight to categorize weight health. Those with a BMI over 30 are considered obese (Table 1). Medical studies have shown that obese individuals are more prone to surgical complications such as infection and wound healing problems that may require additional surgery. They are also at greater risk from anesthesia. Patients with a BMI over 30 are therefore higher risk candidates for surgery. Weight loss is strongly recommended prior to surgery to reduce this risk.
