We assess each patient to determine their best course of treatment. A key indicator of treatment is body mass index (BMI). Calculate your BMI. We also consider a patient’s overall health, lifestyle and personal preferences. Typically, patients with a BMI of 35 or less are considered candidates for non-surgical medical treatment. Surgical candidates are patients with a BMI of 36 or greater who have significant associated health conditions, or patients with a BMI of 40 or higher.
