However, in this surgery, intestines are rearranged to make the body take in fewer minerals, which causes patients feel dumping pattern symptoms that discourage patients from consuming harmful foods.

This surgery is performed by cutting and stapling the top part of the stomach to produce a small pocket at the esophagus end, leaving the remaining part of the stomach, connected to the top part of the small intestines. The end of the small intestine, which is still linked to the non-pouch part of the stomach is taken and attached it to the base of the Roux limb. This will allow the digestive liquids, produced by the abdomen, to assemble with the food in the small intestines.


Gastric Sleeve

This is also done to reduce the size of the stomach, which will make the patient feel full sooner following eating.

This type of weight loss surgery is performed by eliminating a huge part of the stomach to produce a long pouch, which joins the esophagus to the small intestine. The pouch is fastened and the rest of the abdomen is removed. Some doctors take an extra step to strengthen the staple line.

Gastric Balloon

This procedure is usually done by first bringing the patient to the sedative condition. A mouth guard made of plastic is then inserted into the mouth of the patient for the scope to go through. After the scope is passed, it is removed and a balloon, inflated with a saline solution or air is inserted into the stomach of the patient. The scope is again passed to confirm the appropriate balloon positioning.

vBloc Therapy

vBloc Therapy is an implanted appliance that blocks the vagal nerve periodically and prevents it from delivering appetite signals to the brain, making the patient feel full between meals and full quicker, following smaller meals.

First, the surgeon will insert the vBloc Therapy appliance below the rib cage of the patient just below the skin. The device will then be attached to the vagal nerve of the patient through two wires. This type of weight loss surgery can be completed between one hour and 1.5 hours.
