Gastric Bypass

Different types of gastric bypass surgeries


Gastric bypass is the common name giving to different kinds of weight loss surgeries that involves bypassing a part of small intestines. Generally the surgery involves cutting up the stomach into two . The smaller first pouch and a bigger pouch. These two are then re-attached to the small intestines in differnet ways. Hence different types of the sugery.

Weight loss surgeries are either mal-absorptive meaning they reduce rate of calorie absorption or restrictive. Restrictive surgery involves restricting the amount of food you can hold.The gastric bypass method involves combining these two effects in the same procedure to reduce calorie intake, reduce appetite and reduce calorie absorption to result to weight loss. 

In particular gastric bypass involves reducing the functional size of the stomach into the small first pouch into the size of a golf ball to the size of a tennis ball. This reduces calorie intake as well as appetite. Due to the small stomach you eat less. And since it fills with just a small amount of food your brain gets the signaling that your stomach is full. 

It further involves re-arranging the intestines to allow the food eaten to bypass most of the absorption hence the name gastric bypass. 

It is this severe mutilation of the digestive system that makes many uneasy about weight loss surgery. However if you can find an appropriate weight loss program then you can lose weight without having to undergo surgery. 

For example a common error in losing weight is obssesing about calories. Actually to lose weight fast, easily and permanetly you should ignore calories. Infact you need to "Go Beyond Calories" and focus on two things, just two things. Watch this short video below to see these two things... 


Losing weight with this kind of surgery is usually drastic and dramatic. 

The procedures usually end up having both a physiological as well as psychological effect which leads to this huge drop in weight. Many doctors offices and hospitals specialize in gastric bypass surgery. It takes a well rounded staff to ensure that each patient is taken care of from the time they come in for their assessment and insurance clearance, to the time they leave to go home for recovery. One of the key roles in this is that of a healthcare administrator. Those that are interested in this, may consider a CSU Global bachelor of science in healthcare administration.

Types of Gastric Bypass

Basically there are three types of bypass procedures 

Roux-en-Y Stomach Surgery:

In this procedure, the upper part of the stomach is separated from the rest of the stomach using weight loss staples or a plastic bonding. 

This creates the small pouch. The surgeons then connect the small pouch directly to the lower end of the smaller intestines. 

This way the food comes through the oesophagus after swallowing into the small stomach pouch and out through the lower end of the small intestines called Jejunum and finally to the large intestines (colon). 

The procedure allows the food to by-pass the upper end of the small intestines (duodenum). It also has the distinctive "Y" connection of the "amputated" intestine (duodenum) where it is reconnected to the rest of the intestines to deliver digestive juices. 

Since it’s at the duodenum that a lot of dietary fat is absorbed the procedure help further reduce calorie intake by reducing fat absorption. Roux-en-Y and it’s close variance are the most common bypass surgeries. 

Mini-Gastric Bypass Surgery:

This procedure is usually done laparoscopically and takes only about 30 minutes. 

Unlike most gastric bypass, the mini-procedure does not create a small pouch. 

Rather it staples the stomach into a tube on the less curved side of stomach which is directly attached to the lower end of the intestines. 

The process allow minimal cutting of the intestines hence the term mini otherwise it is similar to Roux-en-Y. 

It has the advantage of shorter hospital stay and is even insinuated to have better results than Roux-en-Y.

Biliopancreatic Diversion:

This procedure is more mutilating than the other two. It involves completely removing the large secluded section of the stomach. The small pouch is then also attached to the lower end of the small intestines. The upper end of the intestines that is usually normally connected to the stomach is sealed and left un-attached within the abdominal cavity. 

As opposed to all other gastric bypass procedures in this operation about half of the stomach is removed completely. (Note not nearly the whole stomach). This is done vertically rather than horizontally which is normally the case when creating the small stomach pouch. 

Vertical removal is nearly similar to the mini gastric bypass, only that in this case the stomach is larger than a narrow tube. Similarly unlike the other procedures, the natural pyloric valve that controls the release of food from the stomach is left intact. 

Also left intact is some significant length of upper small intestines (duodenum). This is unlike the other procedures that completely eliminate and bypass the duodenum. This short duodenum is connected directly to the lower end of intestines bypassing the middle intestines. 

This procedure has two slightly varying forms. 

By the very nature of gastric bypass the procedure are usually irreversible, so careful consideration should be put into choosing surgery to lose weight. And as a technique bariatric surgery is really a support structure to help you change your lifestyle. 

The fact that these procedures are irreversible is a primary reason you should get  informed. You want to make informed decisions so you donot have to be stuck with a life permanent condition you could have choosen different.

You see when it comes to losing alot of body fat, there are two primary things you should do. These two will lead to weight loss in the hundred of pounds over time, because they put your body in a natural state of fat burning which in turn results to consistent weight loss.

Even more importantly, if you want to lose belly fat and get a flat stomach or even a six pack; you need to "Go Beyond Calories. You need to "Go Beyond Calories" and focus on two things, just two things. These two are....
