1. Most of the people who have had
weight-loss surgery start to regain weight after two years, (NIH Statistic) and
some actually gain all the weight back. Why go through a surgery
that doesn't work?
this surgery, most people are not able to eat more than a tiny bit
of food at any one time. If you eat more than a half a cup of
food, you may throw up.
3. After this surgery, many
people find they have to stay close to a bathroom because of
severe diarrhea. This kind of diarrhea comes from food that isn't
digested correctly, so it is especially bad smelling.
4. After this surgery, many
surgery patients find that they can't eat any fruits or
vegetables. Some can't eat any food with fat in it or they will
throw up. Some have to drink hot liquids with their meals to
soften their foods. Some have to eat only liquid foods, so they
have to put everything through a blender and drink it. And
according to the US government, nearly 30% of surgery patients
develop nutritional deficiencies like anemia or osteoporosis. (NIH Statistic)
5. Ten to twenty percent of
weight-loss surgery patients have to go back into the hospital one
or more times to correct problems that were caused by the
surgery. (NIH Statistic) Some of these problems are:
a. the surgical incision can
b. you can get a hernia
where the incision was
c. the surgery can make a
hole in the stomach that can bleed and get infected
d. the surgery can make a
hole in the intestine that can bleed and get infected
e. if the surgery puts
staples in, the staples can pop; the same with inserted bands.
f. more than one-third of
weight loss surgery patients develop gallstones! (NIH Statistic)
g. every new kind of weight
loss surgery has its own possible complications
6. Some people who have
weight-loss surgery need to go back into the hospital to have the
surgery reversed because the problems are so severe that the
person could die.
7. The surgeons who do
weight-loss surgery don't tell patients about all the bad side
effects because they don't want to frighten the patients. We think
you should know before you decide. For more information, go to
this Informational Website to read both the benefits and risks of the surgery.
8. If you have the surgery, the
surgeon may not be the doctor who will take care of you. Instead
you would see an internist or a gastroenterologist. So we think
you should get a second opinion from one of those doctors before
making this life-changing decision. Most gastroenterologists do
not recommend weight-loss surgery, because they have seen the
health problems it can cause.
9. Medical science does not know
enough about how our bodies work yet. Weight-loss surgery is an
experiment, and people are the guinea pigs. We think people who
want to lose weight should wait until doctors and scientists come
up with a way that is absolutely proven to be completely safe and
completely effective. Until then, find other ways to improve your
health and well-being.

Weight Loss Surgery
by Paul Ernsberger, PhD.
Paul Ernsberger, PhD, Case Western
Reserve School of Medicine, wrote this commentary in response to a
reporter's request for information on the controversial subject of
weight-loss surgery. November 1999.
This is an issue where it has been
very difficult to get a balanced perspective. In my experience,
most physicians, especially academic physicians, disapprove of
these operations. However, they will only admit this in private,
because of an unwritten law in medicine that forbids one to speak
ill of another's procedure. Thus, there is no one with an MD after
their name who will appear on camera and criticize the operation.
If you do persist in trying to find one, I suggest talking to some
gastroenterologists. These are the specialists who have to take
care of patients suffering long-term complications from the
operations. The surgeon typically only sees the patient for a few
follow-up visits --the ones who suffer complications or regain the
weight are too angry or ashamed to return to the surgeon. So the
surgeon gets a biased picture --only the successes come back. Part
of this is because it is drilled into the patient that if the
surgery fails it is "their fault" because they "out ate" the
surgery (i.e. consumed more than 3 ounces of food per meal).
1. All of the operations, old and
new, are based on an incorrect assumption: that the stomach is no
more than a passive sac for receiving food. In fact, it is a
critical digestive organ and cannot be cut away or bypassed
without compromising the digestive process.
2. The operations work by forcing
the patient to consume small meals. If a meal of more than 3
ounces is consumed, the patient will vomit. Vomiting is very
frequent for some patients, but they will not often admit it,
because they have been told that the vomiting is "their fault".
The operations follow the same concept as wiring the jaws shut--an
involuntary restriction of food intake.
3. The stomach is very
expandable, and over a period of years will regrow. If part of the
intestine is bypassed, the remaining intestine will also adapt.
The result is that weight loss peaks at about two years after the
operation (versus one year after older types of surgery), and then
there is a gradual but accelerating regain of weight. Certainly,
surgeons can bring forward patients who have kept the weight off,
but the same is true for every weight loss plan. The difference
with surgery is that the rearrangement of your digestive tract is
permanent and so are the side effects --even though the weight
loss is temporary. This is an important point because the typical
persons getting the operation is a 30-year-old woman. Extremely
obese 30-year-old have 40 years of life expectancy (versus 45
years of they were thin). Thus, to actually extend lifespan the
surgery must keep weight off for life. This is not likely unless
new operations are done every 5 to 10 years.
4. Almost every surgeon does a
different operation. This should tell you that there is no ideal
operation. If the surgery was so wonderful, why are all the
surgeons experimenting with different techniques? Also, why has
there been no animal testing of these operations, as there is with
every other kind of surgery?
To summarize about the new
surgeries, they all follow the same principle as the old surgery.
The laparoscopic procedure is faster and will allow surgeons to do
a greater number of operations in less time, but the effects on
the digestive tract and the absorption of nutrients into the
bloodstream will be the same.
