While an excellent procedure for body contouring, liposuction is not a true weight loss procedure. As mentioned by others, a bariatric weight loss procedure such as a band, bypass, or gastric sleeve will give you significant weight loss in a relatively short period of time (1-2 years). These procedures are best followed up by a procedure to remove the excess skin that you will likely have after the weight loss. Typically it is best to be stable at, or close to, your desired weight for 6-12 months. You should be aware that insurance companies will commonly cover a portion of the skin removal from your abdomen, but not the entire procedure. Insurance companies tend not to cover any additional surgery you may need (arms, thighs, neck, upper abdomen, breasts). Massive weight loss is a serious undertaking and the health benefits are amazing, however, be aware of all that comes with it. Best of luck in your pursuits!
