Gastric Bypass Methods

Gastric bypass procedures have increased in regularity recently, due mainly to the growing number of incidences of obesity in the US.

There are two main methodological variants within gastric bypass surgery today, the original ‘loop’ method, pioneered in the 1960s having been largely abandoned. Presently, the most commonly used method in gastric bypass surgery is the Proximal, or Roux en-Y system.

 



Gastric Bypass Can Be Necessary

In some instances, gastric bypass can be a necessary treatment for morbid obesity. Many individuals find that even conscientious dieting has not helped them lose weight, and that their weight is causing multiple health concerns. Morbid obesity can cause diabetes, heart disease, high blood pressure and more. While gastric bypass surgery does involve some risks, it can be a lifesaving and life changing procedure for some individuals.

If your physician believes gastric bypass surgery is necessary for your health, discuss all your options. Is the risk of obesity at this point in your life greater than the risk of the gastric bypass procedure? Actively working to lose some weight prior to the procedure can make your recovery easier and lessen the surgical risks of the gastric bypass.

Gastric bypass surgery can offer you a new lease on life if it is a necessary procedure. The many health risks associated with morbid obesity will rapidly lessen as you lose weight following your gastric bypass. If the surgery is truly necessary, the lasting medical implications and side effects of gastric bypass surgery will be well worth the benefits to your life long health.

Gastric bypass may be considered a necessary procedure for those individuals who have a body mass index of 40 or higher, or whose weight is causing significant and potentially fatal health concerns. Individuals carrying smaller amounts of excess weight or without weight related health problems should look to diet or exercise for weight loss. Gastric bypass can be a necessary and lifesaving procedure, but it is not one that should not be taken lightly or without consideration.


After Proximal, or Roux en-Y gastric bypass surgery, the amount of food which can be eaten by a patient is severely restricted because, after swallowed, it moves into a small upper gastric (stomach) pouch, separated from the remainder of the stomach in surgery. From here, food then moves gradually into a ‘Roux limb’ of small bowel formed in surgery, bypassing the rest of the stomach and the initial part of the small intestine. This causes the patient to absorb fewer calories.

The other main form of gastric bypass surgery is the biliopancreatic diversion. This is a more complicated and less typically carried-out procedure. In its being carried out, portions of the patient’s stomach are literally removed. The small pouch of the patient’s stomach remaining is then directly connected to the end section of the small bowel, thus bypassing the rest of the intestine and, again, reducing calorie intake by the patient. Whilst this more drastic procedure is more regularly successful in facilitating weight loss, it is not nearly so widely carried out. This is because it carries with it a high risk of introducing inadvertent deficiencies to the digestive system.
