Hi. Thank you for your question. With a weight of 270lbs and a height of 5'9, your current BMI (Body Mass Index) is 39.87. That is a morbid obesity state. Specifically a obesity class 2 (almost class 3, which starts at 40, and is the top level). You need special care of your weight. Please visit a nutrition specialist, or if diet is not enough for you, consider bariatric surgery first as a long term solution. You will always have time for a aesthetic plastic procedure at the end. Good luck
At 270 pounds and 5'9" you are very overweigth. You need to lose weight and then be evaluated for the BBL. You may need a nutritionist to hepl you lose weight. After weight loss you should consult with a Board Certified Plastic Surgeon with extensive experience in performing the BBL.Good luck!
