Excess weight affect our lives? The facts about
obesity
Individuals are considered severely overweight,

Obesity means that your excess weight is putting
your life at risk.
You are considered obese or morbidly obese if
you are:
- More than 45
kgs over your ideal weight

is 40 or greater

is 35 or greater and you have life
threatening conditions related to obesity

Why Weight
Loss Surgery?
It is now understood that severe obesity is not
just the result of excess eating but a chronic
disease with many contributing factors. Surgical
procedures have shown the best long-term results
in dealing with obesity.
BODY MASS INDEX (BMI)
BMI is used to estimate your best weight range
for your health. It is calculated by dividing
your weight in kilograms by your height in
metres squared (m2).

Failed to
lose weight through diet and exercise?
While a healthier diet and exercise can result
in weight loss, the real challenge is keeping
the weight off. Unfortunately, studies show a
nearly 100% failure rate during a five year
period for obese persons who diet for weight
control.
For those who have tried diet and exercise
without success, weight loss surgery may be the
best way to regain your health and lifestyle.
Who is suitable?
Your doctor will discuss with you the
indications for weight loss surgery and will
determine if surgery is appropriate for you. In
general, your doctor will consider your weight
versus ideal body weight standards, previous
experience losing weight with non-surgical
methods and your commitment to follow the strict
diet, exercise and medical guidelines associated
with the procedure. In addition to these
considerations, there are some pre-existing
medical conditions that are contra-indicated for
weight loss surgery.
What risks
are involved in weight loss surgery?
As with any surgical procedure, weight loss
surgery presents risks. It is important that you
discuss with your surgeon the specific risks for
someone with your conditions and undergoing your
specific procedure.
Which weight loss surgery option is
right?
There are two main approaches to weight
loss surgery. Discuss with your surgeon which
one is right for you:
- Restrictive
surgery
Bands or staples are used to section off a
part of the stomach, creating a pouch.
Because this stomach pouch is so small, the
amount of food one can eat is limited. Food
continues to be digested through the normal
digestive and absorption process.
Most restrictive procedures involve the use
of a polymeric silicone ring or mesh band
around the stomach. This band provides
stability by not allowing the pouch outlet
to expand.
One example is the Swedish adjustable
gastric band Laparoscopic surgery. The
Swedish Adjustable Gastric Band causes the
section of the stomach sitting above the
band to hold a small amount of food. As this
section of the stomach fills and stretches,
the body sends signals to the brain that the
stomach is full and consequently you feel
satisfied and eat less.
As your eating patterns change and you
become accustomed to eating less, you can
achieve sustainable weight loss, which in
turn will lead to a healthier lifestyle with
less risk of obesity related health problems.
With a Swedish Adjustable Gastric Band
procedure, using keyhole surgery,
your normal anatomy has not been altered and
there is no impact to your normal digestive
processes. The food you eat will be absorbed
by your body exactly as it was before
surgery.
- Restrictive
with malabsorptive
This procedure restricts both food intake
and the amount of calories and nutrients the
body absorbs. In addition to creating a
stomach pouch, the surgery disrupts the
body's normal digestive process. As a
result, food bypasses a large part of the
stomach and most of the small intestine.
- Roux-en-y gastric bypass
The Roux-en-Y Gastric Bypass procedure
combines restrictive and malabsorptive
procedures. During the Roux-en-Y procedure,
stapling is used to create a small, upper
stomach pouch, which restricts the amount of
food able to be consumed.
A portion of small bowel is bypassed, thus
delaying food from mixing with digestive
juices to avoid complete calorie absorption.
In most cases, patients report an early
sense of fullness, that reduces the desire
to eat. As with the purely restrictive
procedure many health problems i.e. back
pain, sleep apnoea, high blood pressure,
diabetes and depression, may improve or be
resolved following surgery.
