Weight Loss Introduction
Gastrointestinal surgery is an option for people who are severely
obese and cannot lose weight by traditional means or who suffer
from serious obesity-related health problems. The operation promotes
weight loss by restricting food intake and, in some operations,
interrupting the digestive process. As in other treatments for obesity,
the best results are achieved with healthy eating behaviors and
regular physical activity.
Gastrointestinal surgery for obesity, also called bariatric surgery,
alters the digestive process. The operations can be divided into
three types: restrictive, malabsorptive, and combined restrictive/malabsorptive.
Restrictive operations limit food intake by creating a narrow passage
from the upper part of the stomach into the larger lower part, reducing
the amount of food the stomach can hold and slowing the passage
of food through the stomach. Malabsorptive operations do not limit
food intake, but instead exclude most of the small intestine from
the digestive tract so fewer calories and nutrients are absorbed.
Malabsorptive operations, also called intestinal bypasses, are no
longer recommended because they result in severe nutritional deficiencies.
Combined operations use stomach restriction and a partial bypass
of the small intestine.
Obesity Information
Overweight refers to an excess of body weight, but not necessarily
body fat. Obesity means an excessively high proportion of body fat.
Health professionals use a measurement called body mass index (BMI)
to classify an adult's weight as healthy, overweight, or obese.
BMI describes body weight relative to height and is correlated with
total body fat content in most adults. To get your approximate BMI,
multiply your weight in pounds by 703, then divide the result by
your height in inches, and divide that result by your height in
inches a second time. (Or you can use the interactive BMI calculator
at www.nhlbisupport.com/bmi/bmicalc.htm.) >> More
BMI Calculator
A BMI from 18.5 up to 25 is considered in the healthy range, from
25 up to 30 is overweight, and 30 or higher is obese. Generally,
the higher a person's BMI, the greater the risk for health problems,
according to the National Heart, Lung and Blood Institute (NHLBI).

Weight Loss Surgery Types
Purely restrictive operations for obesity include adjustable
gastric banding (AGB) and vertical banded gastroplasty (VBG). Adjustable
gastric banding. In this procedure, a hollow band made of silicone
rubber is placed around the stomach near its upper end, creating
a small pouch and a narrow passage into the rest of the stomach
(figure 2). The band is then inflated >> More

Weight Loss Pills
For obese people who have difficulty losing weight through diet
and exercise alone, there are a number of FDA-approved prescription
drugs that may help. "On average, individuals who use weight-loss
drugs lose about 5 percent to 10 percent of their original weight,
though some will lose less and some more," says the FDA's Colman.

Weight Loss Diets
The cabbage soup diet, the low-carbohydrate and high-protein
diet, and other so-called "fad" diets are fundamentally
different from federal nutrition dietary guidelines and are not
recommended for losing weight. Fad diets usually overemphasize one
particular food or type of food, contradicting the guidelines for
good nutrition, which recommend eating a variety of foods from the
Food Guide Pyramid. These diets may work at first because they cut
calories, but they rarely have a permanent effect. A high-protein
diet >> More
Liposuction Weight Loss Treatment
Liposuction is a surgical procedure intended to remove fat deposits
and shape the body. Fat is removed from under the skin with the
use of a vacuum-suction canula (a hollow pen-like instrument) or
using an ultrasonic probe that emulfsies (breaks up into small pieces)
the fat and then removes it with suction. Persons with localized
fat may decide to have liposuction >> More
FDA approved a new surgically implanted device to help severely
obese people lose weight. The product, the Lap-Band Adjustable Gastric
Banding System, made by BioEnterics Corporation of Carpinteria,
Calif., is an inflatable band that is placed around the upper stomach
to create a small gastric pouch. This limits food consumption and
creates an earlier feeling of fullness.
The band is implanted by laparoscopic "keyhole" surgery
and is then adjusted over time--either tightened or loosened--to
meet individual patient needs. Once the band is in place, it is
inflated with saline. Subsequent adjustments are made through a
portal under the skin.
The Lap-Band is intended for severely obese people--those at least
100 lbs. overweight or who are at least twice their ideal body weight--who
have failed to reduce their weight by other methods such as a supervised
diet, exercise and behavior modification programs. Severely obese
people usually have serious health problems such as hypertension,
gall bladder disease, and diabetes, resulting from their excess
weight. For them, being overweight is a serious health issue, not
just a cosmetic problem.
The Lap-Band is intended to remain in place permanently, but it
can be surgically removed, if necessary. People who get the Lap-Band
will need to diet and exercise in order to maintain their weight
loss. Previously the only surgical treatments available for severe
obesity were more invasive procedures such as stomach stapling and
gastric bypass.
The system is used for weight loss in severely obese adults who
have been obese for at least five years and for whom non-surgical
weight loss methods have not been successful. They must be willing
to make major changes in their eating habits and lifestyle. Patients
must have a Body Mass Index (BMI) of at least 40, a BMI of at least
35 with one or more severe morbid (unhealthy) conditions, or be
at least 100 pounds over their estimated ideal weight.
It may help the patient lose weight. In the U.S. study, the average
weight loss was 36% of a patients excess weight three years
after the device was implanted. More than half of the patients lost
at least 25% of their excess weight; some patients lost over 75%,
but some lost no weight. Most patients experienced at least one
side effect. Common side effects include nausea and vomiting, heartburn,
abdominal pain, and slippage of the band. The most serious side
effects required either another operation or hospitalization. It
should not be used for people who are poor candidates for surgery,
have certain stomach or intestinal disorders, have an infection,
have to take aspirin frequently, or are addicted to alcohol or drugs.
It should not be used on patients who are not able or willing to
follow the rules for eating and exercise that are recommended by
the doctor after surgery.
Tips for Choosing a Weight Loss Surgeon:
Check into the experience of the specialist, doctor,
or surgeon you are considering. Does he or she specialize in the
weight loss surgery procedure?
How many weight loss surgeries of this kind has the doctor done?
How many is the doctor currently performing per year?
Weight loss surgery before-and-after pictures can give you some
indication of a surgeon's ability, although you must realize that
they cannot be construed to guarantee the result you will achieve.
Make sure you are comfortable with the personal support between
you and your cosmetic surgeon. You should always feel that your
concerns are being addressed.
