I want to get the gastric banding done but i want to know is it safe or are there risk? i have a problem loosing weight i'm 270 right now

Safe but less effect: Bariatric procedures can be divided into 3 principle effects, causing malabsorption of nutrients, by restricting stomach size or a combination of both. Gastric band and sleeve gastrectomy are restrictive, while gastric bypass is considered to be a combination of restrictive (small stomach pouch) and malabsorptive (bypassing portions of the digestive tract that absorb calories and nutrients).
