If you are considering liposuction after a large weight loss, remember one thing: liposuction will remove unwanted fat, but will not make a significant change in the amount of excess skin or the quality of the skin. In fact, removing just the fat from your upper abdomen may create even more of a defect with worsening of the appearance of your upper abdomen. The cheapest answer will most likely be the biggest waste of money.
You should research your options very carefully. Liposuction or non-surgical fat reduction, like CoolSculpting, will most likely not help with your excess skin, and may actually make you look worse. Based on the images that you provided, an abdominoplasty probably your best option. This surgery can successfully remove excess fat and skin from the abdomen permanently, and is most commonly performed on women after pregnancies or significant weight loss. If you have gone through a gastric bypass or successful weight loss you should take the time to meet with a board certified plastic surgeon that has experience with weight loss patients.

I suggest a careful face-to-face consultation to determine if you are a good, and healthy, candidate for this type of procedure. The procedure can take from two to three hours, and patients usually go home the same day.
Large volume weight loss is difficult, living with the excess skin can be even harder. There are safe options for you to achieve the body imagined, but this is not the time to look for a cheap option that you may spend far more to correct in the future.
