Types of Weight Loss Surgery

In weight loss surgery, the surgeon can make some changes in your intestine or stomach and sometimes in both here are some common methods that surgeons typically use

Gastric Sleeve

In this surgery, the surgeon only left a narrow part of the upper stomach and removes most of the stomach. This kind of surgery is called a gastric sleeve.

This surgery reduces the hunger hormone and you eat less due to feeling full. This hunger hormone called ghrelin hormone.

Duodenal Switch

It is a most complicated surgery in which doctors remove the most part of the stomach by using the gastric sleeve and reduce the area of the small intestine through the bypassing process.

After this surgery, you eat limited and your body has a few chances to absorb nutrients and calories from your food. Which also reduces the number of necessary vitamins and minerals.

Gastric Bypass

This bypass surgery is also called Roux-en-Y or RYGB. In this surgery, the doctors leave a small part of the stomach which named a pouch. The size of the pouch is too small that you eat less. The rest of the food bypass direct to the small intestine.

Sometimes doctors do a mini-gastric bypass. It is the same procedure like a gastric bypass. In this procedure, doctors use many small cameras to see inside the body.

Adjustable Gastric Band

A small band is used to put around the stomach which has a small balloon inside this band. This balloon controls the tightness of the band.

Through this band you can control the limit of intake food,  Laparoscope is used to perform this surgery. Most doctors do not recommend this type of surgery due to its complications.

Electric Implant 

In this surgery, the doctors implanted a device in the abdomen controlled with a remote. This remote is used to control the device. This system is called the Maestro Rechargeable System. 

This system works just like a peacemaker. This device sends signals to the brain to control the nerves between the brain and stomach, to control the appetite.
