Thank you for your question regarding whether you can get a tummy tuck with a BMI of 42. Ideally, your BMI should be less than 30 for elective plastic surgery. However, some patients are unable to obtain this ideal number. Therefore, more and more plastic surgeons are finding that this ideal BMI is often unobtainable for their patients. If you are healthy and deemed medically stable by your internist, it is possible to undergo surgical procedures with a higher BMI. Though it would be ideal for your BMI to be lower, this may be unrealistic. However, I would counsel at least a good 6-8 months of conscientious eating, low carbs high protein, and eliminating sugar and alcohol. I would also suggest 30-40 minutes of exercise every day. With this regimen, I am certain you will lose some weight. If obtainable and you are still healthy, you are still able to have an abdominoplasty even with a high BMI. The goal of plastic surgery is not necessarily to reduce your BMI. The goal of the surgery is to get rid of excess skin and fat associated with weight loss. Another option to consider would be a surgical procedure to address weight loss. I would suggest a vertical gastric sleeve but it is important to consult with a professional weight loss general surgeon. Please seek an expert in your area. The vertical gastric sleeve usually yields excellent results. I hope this helps to answer your question about whether you can undergo a plastic surgery procedure like a tummy tuck or liposuction with a higher BMI. Sincerely, Dr. Katzen.
