What is Gastric Banding Surgery?

Quite seldom people undergo surgeries to accomplish weight loss. Gastric band surgery is one such weight loss surgery. However, this is the most common weight loss surgery and the complete medical name of the surgery is Laparoscopic adjustable gastric banding surgery.

Process during the surgery

In the gastric band procedure, the upper part of the stomach is wrapped around with a silicon band. This creates a small pouch in the upper stomach and larger lower stomach. The band creates a narrow passage which acts as the connector between the two parts of the stomach. Due to this narrow passage, the amount of food eaten during a meal is restricted. Although food can pass from the upper part to the lower region, since the passage is narrow it passes very slowly, so that your stomach feels full for a long time, making you less hungry during the rest of the day. This is done laparoscopically, like the name.

After this weight loss surgery, the gastric band can be adjusted very easily. There’s a balloon that is inflated with saline, in the band’s inner lining. This balloon is used to control the size of the opening thereby adjusting the amount of food to be passed through it.



Gastric band surgery is considered the safest weight loss surgery with fewer complications after the surgery. The most common type of complication people experience after the surgery is vomiting and nausea. This usually happens when the patient eats too much or too fast after the surgery, without enough chewing.  This gastric band surgery results in a weight loss of about 40% of the additional weight in the body. However, this is a very high level of estimation and the actual result can vary depending on many factors such as a patient’s health condition, age, etc. The band can be removed at any time bringing the stomach back to normal size.


There are of course a few, but minor disadvantages of this surgery.

  • Your eating pattern has to change. For example, you eat less and need to eat slowly. Whatever solid food you need should be chewed properly. Also, some foods such as steak, white meat, doughy bread are difficult to be eaten since they won’t pass through the narrow opening. Quite rarely, this narrow passage could get blocked by unsuitable food or large portions of food.
  • Minor complications such as wound infection, adjustment devise issues or bleeding can also take place.
