About Treatment
For anyone who has considered a weight loss program,
there is certainly no shortage of choices. In
fact, to qualify for insurance coverage of weight
loss surgery, many insurers require patients to
have a history of medically supervised weight
loss efforts.
Most non-surgical weight loss programs are based
on some combination of diet/behavior modification
and regular exercise. Unfortunately, even the
most effective interventions have proven to be
effective for only a small percentage of patients.
It is estimated that less than 5% of individuals
who participate in non-surgical weight loss programs
will lose a significant amount of weight and maintain
that loss for a long period of time.
According to the National Institutes of Health,
more than 90% of all people in these programs
regain their weight within one year. Sustained
weight loss for patients who are morbidly obese
is even harder to achieve. Serious health risks
have been identified for people who move from
diet to diet, subjecting their bodies to a severe
and continuing cycle of weight loss and gain known
as "yo-yo dieting."
The fact remains that morbid obesity is a complex,
multifactorial chronic disease.
For many patients, the risk of death from not
having the surgery is greater than the risks from
the possible complications of having the procedure.
That is the key reason that in 2000, approximately
40,000 weight loss surgical procedures were performed
and why the American Society for Bariatric Surgery
estimates that nearly twice that number will be
performed in 2002. Patients who have had the procedure
and are benefiting from its results report improvements
in their quality of life, social interactions,
psychological well-being, employment opportunities
and economic condition.
In clinical studies, candidates for the procedure
who had multiple obesity-related health conditions
questioned whether they could safely have the
surgery. These studies show that selection of
surgical candidates is based on very strict criteria
and surgery is an option for the majority of patients.

Weight Loss Surgery
Weight loss surgery is major surgery. Its growing
use to treat morbid obesity is the result of three
factors:
- Our current knowledge of the significant health
risks of morbid obesity
- The relatively low risk and complications
of the procedures versus not having the surgery
- The ineffectiveness of current non-surgical
approaches to produce sustained weight loss
Surgery should be viewed first and foremost
as a method for alleviating debilitating, chronic
disease. In most cases, the minimum qualification
for consideration as a candidate for the procedure
is 100 lbs. above ideal body weight or those with
a Body Mass Index of 40 or greater. Occasionally
a procedure will be considered for someone with
a BMI of 35 or higher if the patient's physician
determines that obesity-related health conditions
have resulted in a medical need for weight reduction
and, in the doctor's opinion, surgery appears
to be the only way to accomplish the targeted
weight loss. In many cases, patients are required
to show proof that their attempts at dietary weight
loss have been ineffective before surgery will
be approved. More important, however, is the commitment
on the part of the patient to required, long-term
follow-up care. Most surgeons require patients
to demonstrate serious motivation and a clear
understanding of the extensive dietary, exercise
and medical guidelines that must be followed for
the remainder of their lives after having weight
loss surgery (see Life After Surgery).

Diet & Behavior Modification
There are literally hundreds of diets available.
Moving from diet to diet in a cycle of weight
gain and loss - yo-yo dieting - that stresses
the heart, kidneys and other organs can also be
a health risk.
Doctors who prescribe and supervise diets for
their patients usually create a customized program
with the goal of greatly restricting calorie intake
while maintaining nutrition.
These diets fall into two basic categories:
- Low Calorie Diets (LCDs) are individually
planned so that the patient takes in 500 to
1,000 fewer calories a day than he or she burns.
- Very Low Calorie Diets (VLCDs) typically
limit caloric intake to 400 to 800 a day and
feature high-protein, low-fat liquids.
Many patients on Very Low Calorie Diets lose
significant amounts of weight. However, after
returning to a normal diet, most regain the lost
weight in under a year. Ninety percent of people
participating in all diet programs will regain
the weight they've lost within two years.
Behavior modification uses therapy to help patients
change their eating and exercise habits. Like
low-calorie diets, behavior modification, in most
patients, results in short-term success that tends
to diminish after the first year.
If diet and behavior modifications have failed
you and surgery is your next option, it is important
to understand that diet and behavior modification
will be instrumental to sustained weight loss
after your surgery. The surgery itself is only
a tool to get your body started losing weight
- complying with diet and behavior modifications
will determine your ultimate success.

Exercise
Starting an exercise program can be especially
intimidating for someone suffering from morbid
obesity. Your health condition may make any level
of physical exertion next to impossible. The benefits
of exercise are clear, however. And there are
ways to get started.
A National Institutes of Health survey of 13
studies concludes that physical activity:
- results in modest weight loss in overweight
and obese individuals
- increases cardiovascular fitness, even when
there is no weight loss
- can help maintain weight loss
New theories focusing on the body's set point
(the weight range in which your body is programmed
to weigh and will fight to maintain that weight)
highlight the importance of exercise. When you
reduce the number of calories you take in, the
body simply reacts by slowing metabolism to burn
fewer calories. Daily physical activity can help
speed up your metabolism, effectively bringing
your set point down to a lower natural weight.
So when following a diet to attempt to lose weight,
exercise increases your chances of long-term success.
Examples to get you started:
- Park at the far end of parking lots and walk
- Take the stairs instead of the elevator
- Cut down on television
- Swim or participate in low-impact water aerobics
- Ride an exercise bike
Overall, walking is one of the best forms of
exercise. Start out slowly and build up. Your
doctor, or people in a support group, can offer
encouragement and advice. Incorporating exercise
into your daily activities will improve your overall
health and is important for any long-term weight
management program, including weight loss surgery.
Diet and exercise play a key role in successful
weight loss after surgery.

Over-the-Counter & Prescription
Drugs
New over-the-counter and prescription weight
loss medications have been introduced. Some people
have found them effective in helping to curb their
appetite. The results of most studies show that
patients on drug therapy lose around 10 percent
of their excess weight and that the weight loss
plateaus after six to eight months. As patients
stop taking the medication, weight gain usually
occurs.
Weight loss drugs can have serious side effects.
Still, medications are an important step in the
morbid obesity treatment process. Before insurance
companies will reimburse/pay for weight loss surgery,
you must follow a well-documented treatment path.
"Since many people cannot lose much weight
no matter how hard they try, and promptly regain
whatever they do lose, the vast amount of money
spent on diet clubs, special foods and over-the-counter
remedies, estimated to be on the order of $30
billion to $50 billion yearly, is wasted."
