Weight Loss Surgeries
 
Gastric Bypass Roux-en-Y
 
The gastric bypass, also known as the Roux-en-Y bypass, consists of two parts. The first step is to suture the upper part of the stomach and form a small sac in the region, which consequently makes the stomach much smaller and the patient will stop eating and feel satisfied and full. The surgeon then cuts the small intestine and attach the bottom of it to the bottom section of the shrunken stomach sac. This results in absorbing fewer calories since the food is not going to pass through most of the stomach and upper intestine. The surgeon then attaches the bypassed or discarded part of the intestine (upper part) to the end of the small intestine. This section of bypass is still considered as the continuation of the stomach, and for this reason, the digestive juice first passes through the stomach and through the first part of the small intestine, and then through its end. This surgery is not reversible, although in some cases a slimming surgeon may suggest restoring the stomach to its original condition.
 

Gastric Band (adjustable-non-adjustable)​

This surgery involves placing an inflatable band around the upper part of the stomach that carries a small balloon. This causes the top part of the stomach to become a small sac which has a very narrow path to the rest of the stomach. The surgeon then puts the adjustment device under the skin surface, which is attached to the band (ring) via a tube. The balloon may then be inflated to adjust the size of the strap by vacuuming or injecting liquids through the tube. This surgery reduces the amount of food that the stomach can hold and the patient immediately feels full but cannot minimize the absorption of calories and food.
 

Gastric sleeve surgery

 
Gastric sleeve surgery is also known as sleeve gastrectomy. The surgeon removes a large portion of the stomach, leaving only a banana-shape section that is sutured. This surgery is similar to gastric band surgery and will result in reducing the volume of the stomach and early satiety. This procedure is not reversible since the rest of the stomach has been removed. This type of surgery can also be beneficial for intestinal hormones and other factors, including intestinal bacteria, which can affect appetite and metabolism.
 
Gastric sleeve with duodenal switch
In this surgery, like gastric sleeve surgery, the surgeon removes most of the stomach. The surgeon then closes the middle of the intestine and directly attaches the end section to the duodenum, which is known as the duodenal switch. The detached part of the intestine will not be removed from the body and reconnected to the end of the intestine itself which results in bile and pancreatic juice flowing through these sections as well. The balloon is temporary and will remain in the stomach for up to six months and the patient can lose 10% of their excess weight during this period.
 

Gastric balloon surgery​

 
The gastric balloon is a type of restrictive slimming surgery in which a balloon (airless) is inserted through the mouth into the stomach.
After the balloon is inserted, it is filled with a saline solution that makes you feel full and prevents you from feeling hungry. Gastric balloon surgery cannot be performed on people who previously had weight loss surgery, gastrointestinal disease, or liver failure. The most important benefit of this approach is that it does not require hospitalization. The balloon is also temporary and can remain in the stomach for up to 6 months, and the patient can lose 10% of their excess weight during this period.

 


Aspiration therapy

Aspire Assist
 
It is a device that results in weight loss with a restrictive approach. A tube is inserted into the stomach through an incision, which has a disk-like valve near the outer surface of the abdomen. At about 20 to 30 minutes after each meal, the patient connects the tube to a draining device to empty stomach food. This weight loss device reduces about 30% of calories consumed and was approved by the US Food and Drug Administration in 2016.
 

 
Vagal Blockade or vBloc

 
This device is a form of nerve regulator that sends an electrical message to the parasympathetic nerve which induces a message of satiety. Parasympathetic nerves are passing from the brain to the stomach. The device is installed under the chest and functions with the assistance of a remote controller located outside the body.
