Gastric bypass surgery is also referred to as Roux-en-Y (RNY). This form of bariatric surgery allows a patient to be able to lose weight by changing the way your small intestine and stomach processes food that you consume. Performed by a knowledgeable and licensed surgeon at Bariatric Select, the process is done laparoscopically.Because the surgery is done minimally invasive, individuals who are obese may be able to reverse dangerous illnesses such as high blood pressure, type two diabetes, back pain, depression, sleep apnea and other ailments.

While RNY gastric bypass surgery is common in the United States, patients will be comforted to know that weight loss surgery in Mexico can be performed by a qualified and trusted surgeon and in a full-service hospital.

Once the general anesthesia has been administered, the surgeon begins the laparoscopic process with several ¼ to 1 inch incisions in the abdomen. They will then:

  • Examine the abdomen and use surgical staples to design a pouch near the top region of the stomach. This small area will be now be a smaller version of the new stomach. The area can hold as little as four cups of food and as much as six. This restrictive strategy works by restricting the amount of food that the stomach is able to hold.
  • The surgeon will then cut the intestine and attach it to the pouch. This technique is best known as a "Roux-en-Y." Food will now be able to move from the new pouch to middle regions of the small intestine. This form of weight loss is called malabsorptive because it allows food to bypasses the lower areas of the stomach and upper regions of the small intestine.
  • The upper areas of the small intestine are then attached to the middle of the small intestine. This allows the digestive fluids that the stomach produces to flow down the upper areas of the small intestine and through the middle.
  • The incisions are then closed with either stitches or staples.
