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).

    Gastric BypassIn 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.


    • Produces significant long-term weight loss 
    • Restricts the amount of food that can be consumed
    • May lead to increased energy
    • Decreases appetite; prolonged sense of fullness after small meals
    • Typical maintenance of >50% excess weight loss


    • Permanent procedure
    • Requires cutting stomach, stapling and intestinal rerouting
    • Requires patient to follow recommendations for diet, vitamin intake, and clinical follow-up to avoid nutritional deficiencies

    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 reversible.

    Sleeve GastrectomyWith 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 loss.


    • Decreased appetite
    • Prolonged sense of fullness after small meals
    • Decreases cravings for sweets
    • Rapid initial weight loss
    • Laparoscopic procedure is minimally invasive


    • Permanent procedure
    • Requires cutting and removing a portion of the stomach
    • Requires patient to follow recommendations for diet, vitamin intake, and clinical follow-up to avoid nutritional deficiencies
    •  No long-term data

    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 with: 

    • Breathing, pneumonia
    • Blood clots, pulmonary embolism
    • Bleeding
    • Hernias at the site of the incision
    • Infection
    • Death

    Potential Complications Specific to Weight Loss Surgery:

    Listed are some, but not all, of the potential complications.  Your surgeon will discuss additional possible complications as part of the informed consent process.

    Roux-en Y Gastric Bypass (1)

    • Leaks
    • Internal hernia/bowel obstruction
    • Stricture
    • Nutritional deficits/vitamin deficiencies due to malabsorption

    Vertical Sleeve Gastrectomy (2)

    • Leak/dehiscence of staple line
    • Internal hernia/bowel obstruction
    • Gastric acid reflux
