Thank you for your question.
If your BMI is higher than 30 you are at an increased risk of complications occurring. I would recommend getting your BMI down to at least 30 or below. I also recommend that my patients remain at their goal weight for at least 6 months before having surgery done for optimal results. It is important to remember to live a healthy, balanced lifestyle through diet and exercise, even after surgery for best results and to reduce your chance of health related issues. I hope this helps.
Best of luck in your endeavors!
