What is weight loss surgery?
Weight loss surgery includes a good array of procedures performed on people who square measure severely overweight. typically speaking, weight loss is achieved by reducing the scale and volume of the abdomen.
Different types of bariatric procedures
While there square measure many various procedures and variations of procedures, there square measure 3 weight loss procedures that square measure most typically performed within the us. These procedures square measure typically tagged as restrictive, malabsorptive or each. throughout restrictive procedures, the physician creates alittle abdomen pouch, that limits the number of food patients will eat. The smaller abdomen pouch fills quickly, that helps patients feel happy with less food. throughout malabsorptive procedures, the physician reroutes the tiny internal organ in order that food skips some of it. the tiny internal organ absorbs calories and nutrients from food, and avoiding a part of it means several calories and nutrients aren't absorbed the foremost usually performed procedures square measure Adjustable internal organ band, Roux-en-y internal organ Bypass, and Vertical Sleeve operation. sure procedures use each restriction and absorption.

Adjustable Gastric Banding
Gastric
Band Surgery makes you feel full sooner which results in less food
consumed at one time and makes it easier for you to participate in
healthy eating and lifestyle habits. With Gastric Band Surgery, your
stomach is divided into two parts: a small upper pouch and a lower
stomach. The upper pouch can only hold about 4 ounces (1/2 cup) of food.
For this reason, you will feel full sooner and longer than usual. Lap
Band surgery does not change the functions of your digestive system.
Food consumed passes through the digestive tract in the normal route.
Approximately
four to six weeks after gastric band surgery, you will visit your
surgeon and begin a series of periodic procedures to adjust your band.
These gastric band adjustments may be necessary as long as you have your
band in place. Your surgeon may tighten the Gastric Band by injecting
saline into the injection port. As the saline is introduced to the
injection port, it travels through the tube to the Gastric Band. The
addition of saline to the band creates a smaller opening between the
stomach and the upper stomach pouch. This smaller opening pouch
restricts the amount of food you can eat before feeling full.
Roux-en-Y Gastric Bypass Surgery
Gastric
bypass surgery makes the stomach smaller and causes food to bypass part
of the small intestine. You will feel full more quickly than when your
stomach was its original size. This reduces the amount of food you can
eat at one time. Bypassing part of the intestine reduces how much food
and nutrients are absorbed. This leads to weight loss. In normal
digestion, food passes through the stomach and enters the small
intestine, where most of the nutrients and calories are absorbed. It
then passes into the large intestine (colon), and the remaining waste is
eventually excreted. In a Roux-en-Y gastric bypass, only a small part
of the stomach is used to create a new stomach pouch, roughly the size
of an egg. The smaller stomach is connected directly to the middle
portion of the small intestine (jejunum), bypassing the rest of the
stomach and the upper portion of the small intestine (duodenum). This
procedure can be done by making a large incision in the abdomen (an open
procedure) or by making a small incision and using small instruments
and a camera to guide the surgery (laparoscopic approach). A small pouch
is created along the inner curve of the stomach and a segment of the
small intestine is attached to the pouch to allow food to bypass a
portion of the intestine. This results in reduced calorie and nutrition
absorption. It is a restrictive and malabsorptive procedure.
Vertical Sleeve Gastrectomy
During
this procedure a bariatric surgeon removes about 85 percent of the
stomach so that it takes the shape of a tube or sleeve.
This
operation is performed laparoscopically, meaning that the surgeon makes
small incisions as opposed to one large incision. He or she inserts a
viewing tube with a small camera (laparoscope) and other tiny
instruments into these small incisions to remove part of the stomach.
The
tube-shaped stomach that is left is sealed closed with staples. In some
cases, gastric sleeve surgery may be followed by a gastric bypass
surgery or duodenal switch surgery after a person has lost a significant
amount of weight. Called a "staged" approach to weight loss surgery,
this makes the second procedure less risky than it would have been had
it been the first and only procedure.
