How safe it is to do a tummy tuck on a patient with a BMI of more than 50
It would be a high risk procedure. Risks would include wound infection, hematoma, seroma, delayed healing, deep venous thrombosis, pulmonary embolism, myocardial infarction, and even death. I do not perform tummy tucks on any patient with a BMI over 35, and preferably below 30. Morbidly obese patients should consider bariatric surgery first to reduce the weight.
Is it the right thing for you to do?
Perhaps start with an aggressive lipo with skin shrinkage(J Plasma/Renuvion) in order to reduce the surgical risk as well as allow time for diet to reduce intraabdominal fat stores which are extremely unhealthy and can interfere with an optimal abdominoplasty result.
Dr. Johnson is correct. You should not consider any operation except a bariatric procedure-and a bypass will lead to greater weight loss than a sleeve gastrectomy. After your weight loss has stabilized, which will take more than a year, you can consider a panniculectomy to remove the redundant tissue.
It would be an extremely risky procedure. You are exposed to complications around the time of surgery such as bleeding, heart attack, DVT / Pulmonary Embolism.
After surgery there is a significantly increased risk of surgical site infections, wound break down and seroma.
Overall the aesthetics of the procedure will most likely be suboptimal.
