Hi and welcome to our forum! At your present weight, you would achieve a degree of improvement with BBL, but the result will not be optimal. Your candidacy for cosmetic surgery requires consideration of many factors. One is measurement of your BMI (body mass index equals weight in kg / square of height in meters). You can find BMI calculators on the internet. If your BMI is > 30, the cosmetic result will not be optimal. If your BMI is > 35, your operative risk will rise. From your height and weight data, your BMI is 33.47, in the "obese" category. Weight loss through diet and exercise is recommended. Your "normal" weight of 167 would represent a BMI of 30.54, a better option. Of importance, it is not worth starving yourself to achieve a "satisfactory" preoperative weight, as you most likely won't be able to maintain it. You should be at a comfortable maintainable body weight (i.e. 6 months or more). Visit a board certified plastic surgeon for evaluation and discussion. Best wishes...
