Hello Honest968010, Thank you for your question regarding the fact that you are four years after weight loss surgery and is a panniculectomy a dangerous surgery? Thank you for your question and history. Thank you for your history of a current weight of 150 pounds. Any surgery can be dangerous. However, certain precautions are taken to minimize potential risks. Before surghery, you will need certain blood test, urine tests, chest Xray, and EKG. If you are over 55 years old, you should obtain a cardiac stress test and carotid duplex study. A pre-operative thorough physical examination will be necessary. These tests and examinations help to stratify your risk of complications. If you are healthy and are "medically cleared" for surgery, you may be a candidate for a panniculectomy. Most plastic surgeons offer free virtual or in-office physical consultations. Therefore, explore what other plastic surgeons have to say. Good luck. I hope that I have answered your question regarding four years after weight loss surgery and is a panniculectomy a dangerous surgery. If you have any more questions regarding the panniculectomy, contact an experienced plastic surgeon. Since the panniculectomy or lower body lift is a big procedure, please seek an experienced, board certified plastic surgeon with significant experience performing the panniculectomy. Do your research. Make sure they have performed at least 100 panniculectomies or circumferential lower body lift surgeries and have the before-and-after pictures to prove it. Carefully examine their before-and-after pictures and check their reviews on RealSelf. If you cannot find an experienced, panniculectomy or lower body lift surgeon in your neighborhood, consider traveling out of state if you must. Sincerely, Dr. Katzen, MD, MBA, FACS, FICS.
