What
You Need to Know About Weight Loss Surgery?
Body:
Weight loss surgery
as a last resort can successfully help severely overweight or obese people lose
excess weight. There are several different types of weight loss surgeries to
choose from. Consult your health care provider to discuss whether or not you
make a good candidate for weight loss surgery, which procedure would work best
for you and whether natural options like Slimirex might be safer and more
effective.
How
Does Weight Loss Surgery Work?
There are two basic
types of weight loss surgery that are currently used for weight reduction.
Restrictive procedures work by decreasing food intake. Malabsorptive
procedures, on the other hand, alter digestion, and cause food to be poorly
digested and incompletely absorbed so that it is eliminated in the stool.
Restrictive
Procedures:
Restrictive weight
loss surgery works by altering the size of the stomach, to reduce the amount of
food that can be consumed at one time. It does not, however, interfere with the
normal absorption or digestion of food. A restrictive weight loss surgery
involves the creation of a small stomach pouch in the upper portion of the
stomach. The capacity of this pouch is about one half to one ounce. The pouch
then connects to the rest of the stomach through an outlet known as a
"stoma." The reduced stomach capacity allows the patient to feel
fuller with less food, and by decreasing overall food intake, the patient can
achieve sustained weight loss. The success of this weight loss surgery
ultimately depends upon the ability of the patient to alter his or her eating
habits. After surgery, it is likely that the patient will only be able to
consume a maximum of one half cup full of food at each sitting. Compliance with
these requirements is necessary to avoid stretching the pouch and defeating the
purpose of the surgery.
* Vertical Banded Gastroplasty: This is
restrictive weight loss surgery in which the upper stomach near the esophagus
is stapled vertically for about 2-1/2 inches to create a smaller stomach pouch.
The outlet or stoma that connects to the rest of the stomach is restricted by a
band or ring that slows the emptying of the food and allows the patient to feel
fuller with less food consumption. After 10 years, studies show that patients
can maintain at least fifty percent of targeted excess weight loss.
* Laparoscopic Adjustable Gastric Banding:
This restrictive weight loss surgery, also called stomach banding, utilizes a
band to divide the stomach into two portions. The band is placed around the
upper most part of the stomach, dividing the stomach into a small upper portion
and a larger lower portion. Because food is regulated, most patients feel full
faster. Food digestion occurs through the normal digestive process. This
surgery can be reversed as the band can easily be removed from the stomach. As
with other weight loss surgeries, the success of this procedure is dependent on
the compliance of the patient with a restricted diet and the development of an
exercise regime.
Malabsorptive
Procedures:
Weight loss
surgeries that alter the digestive process are referred to as malabsorptive
procedures. There are several different types of malabsorptive weight loss
surgery. Some of these techniques involve a bypass of the small intestine,
thereby limiting the absorption of calories. Malabsorptive weight loss surgery
reduces the amount of intestine that comes in contact with food so that the
body absorbs fewer calories.
* Biliopancreatic Diversion: The goal of
this surgery is to restrict the amount of food consumed and alter the normal
digestive processes. It also involves the creation of a stomach pouch, but it
is a larger pouch than one created in a restrictive weight loss surgery.
Biliopancreatic diversion alters the anatomy of the small intestine to divert
the bile and pancreatic juices so they meet the ingested food closer to the
middle or the end of the small intestine. Patients report a greater degree of
satisfaction with this procedure than with restrictive weight loss surgery,
because they are able to eat larger meals. And this surgery provides the
greatest amount of malabsorption, it also allows for the greatest amount of
weight loss. But as with restrictive weight loss surgery, long-term success is
dependent upon the patient's ability to adhere to a dietary, supplement,
exercise and behavioral regimen.
Combined
Procedures:
Gastric Bypass
Roux-en-Y is a recently developed procedure that utilizes the principles of
both restrictive and malabsorptive weight loss surgeries. According to the
American Society for Bariatric Surgery and the National Institutes of Health,
Roux-en-Y gastric bypass is the most frequently performed weight loss surgery
in the United States. This procedure involves the creation of a small stomach
pouch with the remainder of the stomach completely stapled shut and divided
from the pouch. The outlet from the pouch than empties directly into the lower
portion of the jejunum, thus bypassing calorie absorption. By adding malabsorption
to a restrictive weight loss procedure, food is delayed in mixing with bile and
pancreatic juices that aid in the absorption of nutrients. The result is an
early sense of fullness, combined with a sense of satisfaction that reduces the
desire to eat.
