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.
