Gastric Sleeve
Gastric sleeve also known as sleeve gastrectomy, is a surgical process in which the stomach is reduced into a sleeve-like thin tube, by doing that the surgeon isolates and closes most of the stomach, leaving only a small part of the stomach.
Stomach Balloon
A stomach balloon also known as the gastric balloon is a special balloon filled with liquid material. This balloon is placed into the stomach using endoscopy which is a thin tube that passes through the mouth and esophagus to reach the stomach and leave the balloon there.
The balloon settles in the stomach for about 6 months, reducing the size of the stomach available for food, and this limits the amount of food you can eat before feeling full.
How Are Weight Loss Surgical Procedures Done?
Gastric bypass and gastric sleeve operations are performed using open or laparoscopic surgical techniques.
As for gastric balloon, it is not considered an operation in the true sense, but rather a nonsurgical medical procedure that is performed using an endoscope, as it does not include opening the skin, as in the gastric bypass or gastric sleeve.
