You must understand that safety must be our first priority and your BMI should be 30 or below in order to have a safe procedure.You must know that there is a limit for liposuction because the fat which is obtained by liposuction comes together with blood, electrolytes, protein, etc so removing more than 5-6 litters of fat will put your life at risk and if you have 80, 90 or 100 lbs overweight then 10-12 lbs of liposuction will NOT make any difference on your body added to the fact, that because you have a risky degree of obesity, the surgery itself becomes very risky as well.Try a Nutritionist or a Bariatric surgeon. Losing weight will be the best option.Dr. Cardenas
