At Corpus Christ Medical Center - Bay Area Hospital, we offer several surgical weight loss options to help you on your road to long-term weight loss success.

Each procedure involves modifying the stomach and/or intestines to decrease the amount of food that you can eat, and some procedures change the normal absorption of the food you consume. After recovery, it is essential that patients work to change their old habits and replace them with such things as healthy food choices, exercise and vitamins.

Read about each bariatric weight-loss procedure to determine which one best fits you and your lifestyle.

Gastric Bypass Surgery

Gastric Bypass Surgery, also known as bypass, is a procedure that uses both restriction and malabsorption to achieve weight loss. It is the most common type of weight-loss surgery. With gastric bypass surgery, staples are used to permanently close off part of the stomach, which 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.

Gastric Bypass surgery is performed laparoscopically, which may allow patients to recover more quickly and experience less scarring than with more invasive procedures. Several small incisions are made and a laparoscopic tool is inserted. There is also a traditional technique that may be used that requires open surgery with a single, long incision.


  • You eat and absorb less food
  • Decreases appetite
  • Prolonged sense of fullness after small meals
  • Rapid initial weight loss
  • Laparoscopic procedure is minimally invasive
  • Greatest percent of excess body weight lost in a shorter period of time


  • Requires cutting stomach, stapling and intestinal rerouting
  • Requires patient discipline/commitment to avoid nutritional deficiencies and malnutrition

Adjustable Gastric Banding Surgery

Laparoscopic Adjustable Gastric Banding, or "banding", is a restrictive procedure in which a silicone band is placed around the upper part of the stomach. This creates a much smaller stomach pouch. The band also slows the passage of food from the stomach into the intestine. This allows you to feel full for a much longer time after eating.

How It Works 

  • Inflating the balloon inside the band with the saline solution further restricts the opening through which food passes. This reduces the amount you can eat and slows the passage of food. You feel full longer after eating.
  • Deflating the balloon inside the band by removing some of the saline solution increases the opening through which food passes. This can be helpful if you develop certain problems, like regurgitation of food.


  • You eat less
  • Prolonged sense of fullness after small meals
  • Less invasive procedure
  • Shorter operating time
  • Can be an outpatient procedure
  • Adjustable
  • Reversible
  • Helps improve obesity-related conditions
  • Less risk of nutritional deficiencies and malnutrition


  • Slower weight loss over a longer period of time
  • Requires implant
  • Requires frequent follow-ups and adjustments
  • Requires strict diet change

Laparoscopic Sleeve Gastrectomy

Laparoscopic Sleeve Gastrectomy is a restrictive bariatric surgery. During this procedure, the surgeon removes about 80% of the stomach which leaves a small, sleeve-shaped pouch that is larger than the stomach pouch created during RYGB, and is about the size of a banana. Weight loss occurs because the procedure causes the stomach to tolerate a limited amount of food, causing a feeling of fullness more quickly.


  • You eat less
  • Decreased appetite
  • Prolonged sense of fullness after small meals
  • Rapid initial weight loss
  • Laparoscopic procedure is minimally invasive


  • Permanent procedure
  • Requires cutting and removing a portion of the stomach
  • Requires patient discipline with diet to avoid nutritional deficiencies and malnutrition
  • No long term data
