According
to the American Society for
Bariatric Surgery and the NIH,
roux-en-y gastric bypass is
the current gold-standard procedure
for weight-loss surgery. One
of the most frequently performed
weight-loss procedures in the
United States, it is surgery
that significantly reduces the
amount of food that can be eaten
at one time, and somewhat reduces
the amount of calories and nutrients
the body absorbs, thus creating
a restrictive and malabsorptive
approach to losing weight. In
this procedure, surgical
“stapling” creates
a small stomach pouch. The remainder
of the stomach is not removed,
but is completely stapled and
shut and divided from the stomach
pouch. Ultimately, the “old”
stomach and the first portion
of the small intestine are “bypassed,”
thus delaying food from mixing
with digestive juices to avoid
complete calorie absorption
The lower portion of the intestine
is now joined to the new stomach
pouch, creating a y-shaped connection.
In most cases, patients report
an early sense of fullness,
combined with a sense of satisfaction
that reduces the desire to eat.
Advantages
of this procedure include weight-loss
ranging from 60 percent to 75
percent of excess body weight
over the first two years, and
an improvement in the majority
of obesity-related medical conditions,
including diabetes, high blood
pressure and sleep apnea.
Disadvantages
or risks include poor absorption
of vitamins, minerals, iron and
calcium resulting in the lowering
of total-body iron and a predisposition
to iron-deficiency anemia and
metabolic bone disease in some
patients. Chronic anemia due to
vitamin b-12 deficiency also can
occur. These deficiencies can
be managed through proper diet
and vitamin and mineral supplement.
A condition known as “dumping
syndrome” can occur as a
result of rapid emptying of stomach
contents into the small intestine.
This is sometimes triggered when
too much sugar or large amounts
of food are consumed. While generally
not considered to be a serious
risk to your health, the results
can be extremely unpleasant and
can include nausea, weakness,
sweating, fainting and diarrhea.
Lap band adjustable gastric banding
is a restrictive surgical procedure
that limits the
amount of food that can be eaten
at one time. An adjustable silicone
band is placed
around the upper part of the stomach,
creating a small “stomach”
or reservoir that
causes most patients to feel full
faster. Food digestion occurs
through the normal
digestive and absorptive process.
This procedure is less invasive
than other
surgical techniques and the band
can be adjusted or removed. Other
advantages
include shorter hospital stays
and quicker recoveries. Weight
loss ranges from 35
percent to 45 percent of excess
body weight.
Possible complications
of this procedure include band
erosion and esophageal dilatation,
outlet obstruction, pouch dilatation
and band slippage.
It may take
up to 6 months for your surgery
to be scheduled.
Our program has
found optimal results are obtained
with the involvement of a multidisciplinary
team approach. We require
the following to participate
in the program:
-
Initial
consultations with : Surgeon,
Registered Dietitian, Clinical
Psychologist
-
Pre
operative visit with: Surgeon,
Registered Dietitian, Clinical
Psychologist
-
1 week post operative visit
with the Surgeon
-
6 week post operative visit
with the Surgeon, Registered
Dietitian, Clinical Psychologist
-
Documentation of attendance
of 2 support group meetings
before surgery
-
Reports from all required
testing and medical clearance
-
Participation in Remedy MD
data base
The actual weight a patient will
lose after the procedure is
dependent on several factors.
These include:
-
Patient's
age
-
Weight before
surgery
-
Overall condition
of patient's health
-
Surgical
procedure
-
Ability to
exercise
-
Commitment
to maintaining dietary guidelines
and other follow-up care
-
Motivation
of patient and cooperation
of their family, friends and
associates
In general,
weight loss surgery success
is defined as achieving loss
of 50% or more of excess body
weight and maintaining that
level for at least five years.
Clinical data will vary for
each of the different procedures
mentioned on this site. (Keep
in mind that results may also
vary by surgeon.)
Clinical studies
show that, following surgery,
most patients lose weight rapidly
and continue to do so until 18
to 24 months after the procedure.
Patients may lose 30 to 50% of
their excess weight in the first
six months and 77% of excess
weight as early as 12 months
after surgery. Another study
showed that patients can maintain
a 50-60% loss of excess weight
10-14 years after surgery. Patients
with higher initial BMIs tend
to lose more total weight. Patients
with lower initial BMIs will
lose a greater percentage of
their excess weight and will
more likely come closer to their
ideal body weight. Patients with
Type 2 Diabetes tend to show
less overall excess weight loss
than patients without Type 2
Diabetes. The surgery has been
found to be effective in improving
and controlling many obesity-related health
conditions. Additional studies
have shown that 96% of certain
associated health conditions
(back pain, sleep apnea, high
blood pressure, diabetes and
depression) are improved or resolved.
For example, many patients with
Type 2 Diabetes, while showing
less overall excess weight loss,
have demonstrated excellent resolution
of their diabetic condition,
to the point of having little
or no need for continuing medication.
