BIOS is short for Basic Input Output System. It is much more than the name suggests. One might think that BIOS controls input and output system.

Four common types of weight-loss surgery are: 1  Roux-en-Y gastric bypass. 2  Laparoscopic adjustable gastric banding. 3  Sleeve gastrectomy.  Duodenal switch with biliopancreatic diversion.
In contrast to gastric banding, gastric bypass (sometimes referred to as roux-en-Y gastric bypass) is a permanent reduction in the size of the stomach. Gastric bypass is the most common type of weight loss surgery. It makes up about 80% of all weight loss surgeries in the U.S., and combines both restrictive and malabsorptive approaches. The proximal portion of the stomach is used to create an egg-sized pouch that is connected to the intestine in a location that bypasses about 2 feet of normal intestine.
