Thank you for your question.There is no doubt that your risks are higher (infection, skin necrosis, heart problems, lung problems, etc.) and that extra precautions will be required prior to embarking in an elective surgery.We also know that removing your apron will help you in the long run in getting back to exercising and a better health. The panniculectomy may also positively affect your sugars, your heart and your blood pressure. Bringing your BMI under 30 would be beneficial but not always easy to achieve.You should not be a smoker.You endocrinologist will need to be involved to control your sugar levels preoperatively and also to guide the dosage around the surgery.More importantly, your congestive heart failure needs to be quantified and optimized by the cardiologist. Do we know what the congestive heart failure is due to? Any previous heart condition? valve issue? etc.The panniculectomy is a shorter procedure than a tummy-tuck (abdominoplasty) and likely safer in your situation; the idea is to remove the excess of skin only and close. In Canada, the panniculectomy does not include muscle tightening, liposuction nor umbilicoplasty.Your procedure in Canada would be done in a hospital setting. Make sure you seek a board-certified plastic surgeon.Let us know if this information was useful and good luck. Best regards, Dr. Marc DuPéré, Toronto aesthetic plastic surgeon and body surgeon
