Surgical Weight Loss Options
Our board-certified surgeons have expertise in minimally invasive and laparoscopic bariatric surgery, and routinely perform two weight loss surgery options: Roux-en-Y Gastric Bypass and Vertical Sleeve Gastrectomy. Read more about these procedures, as well as risks and complications for bariatric surgery below.
Laparoscopic Roux-en-Y Gastric Bypass surgeries are combination
procedures that use both restriction and malabsorption to achieve weight loss. They
are the most common types of weight-loss surgery performed. The most frequently
performed type of gastric bypass is called the Roux-en-Y Gastric Bypass (RYGB).
RYGB, staples are used to permanently close off part of the stomach. This leaves
only a small stomach pouch for the food you eat. Additionally, a Y-shaped piece
derived from an upper portion of the small intestine is then attached to this small
stomach pouch. As a result, food from your stomach pouch bypasses the initial sections
of the intestine, which normally would absorb calories and nutrients after eating.

Laparoscopic Sleeve Gastrectomy is a restrictive bariatric surgery
procedure, in which approximately 85% of the stomach is removed, leaving a cylindrical,
or sleeve-shaped stomach. Unlike other forms of bariatric surgery, the outlet valve
and the nerves to the stomach remain intact and, while the stomach is drastically
reduced in size, its function is preserved. The sleeve gastrectomy is not
the sleeve gastrectomy, the new sleeve-shaped stomach is larger than the stomach
pouch created during the Roux-En-Y Gastric Bypass, and is about the size of a banana.
Weight loss occurs because the reduced stomach volume only allows for the
ingestion of a small amount of food, which increases the feeling of fullness.
Also, the production of Ghrelin, the “hunger hormone,” is drastically reduced,
therefore enabling patients to control hunger and cravings and enhancing weight
The risks of weight-loss surgery include, but are not limited to, the usual risks
of any surgery, which involves general anesthesia, including potential problems
