hello,BMI screening before any cosmetic surgery procedure is a must, and it is great that you are thinking about this! If a patient is healthy with no health concerns, I require all BBL and Tummy Tuck patients to have a BMI under 35. On the other hand, if you have diabetes or some other medical condition, I would ask you to reduce the BMI to something closer to 32 or below. Based on other surgeon's answers, my BMI35 cut off is indeed higher. This may be in part due to the fact that I use IV anesthesia instead of General Anesthesia. With IV anesthesia, most all of the pulmonary risks are eliminated. With IV anesthesia you are breathing on your own, as opposed to a machine breathing for you with General Anesthesia. Generally speaking, higher BMI patients are at increased risk for pulmonary problems, and General Anesthesia is more tied to pulmonary complications. I have performed hundreds of BBL's over 15 years and this BMI criteria it has served me well.To learn more about BMI screening and the requirements that I require for both BBL and Tummy Tuck patients, please read the link below.Cheers,Ricardo L Rodriguez MD
