Bariatric surgery is considered one of the most ideal ways to lose weight when good nutrition and exercise fail to work. Patients who undergo bariatric surgery are required to eat healthy foods and exercise regularly following surgery to help accelerate the weight-loss process, and to get into the habit of maintaining a healthy lifestyle. In some cases, bariatric patients can end up losing hundreds of pounds within a short period of time, which can result in areas of loose, excess skin.
