You may have seen the
recent headlines that having surgery for obesity can “cure” diabetes. The
Journal of the American Medical Association has published a review of 136
studies of 22,094 patients who had surgery for obesity, also called “bariatric
surgery.” The survey looked at four of the complications associated with
obesity:
- Diabetes
- High blood pressure
- High blood fats
(including cholesterol)
- Sleep apnea
The survey found that a
“substantial majority” of patients undergoing the surgery experienced either
improvement in or a resolution (elimination) of these four health problems.
For anyone who is obese and
has diabetes, this kind of news probably makes you sit up and take notice and
think about whether you should have the surgery yourself. That’s a decision you
and your doctor need to make together, of course.
There’s no question that
people who are obese have a very hard time losing weight and keeping it off.
Statistics show that only about 5 percent of obese people have long-term weight
loss success. Many surgeons who perform bariatric surgery believe that obesity
itself is a disease. They believe that the operation is the best way to help
obese people fight their disease and recover from life-threatening health
problems.
Here are some basics about
the surgery itself and a general description of the type of screening process
that most doctors conduct before agreeing to perform the procedure.
How the surgery works
In the United States, the
most commonly performed obesity surgery is called “roux-en-Y gastric bypass.”
Doctors usually choose this particular procedure because it has a high rate of
effectiveness and a lower rate of complications.
During the operation,
surgeons close off part of the stomach, creating a small pouch. They then attach
part of the small intestine to the pouch. This reduces the amount of nutrients
and calories your body is able to absorb.
As with any type of
operation, bariatric surgery does have complications that may arise, including
infection, tearing or leaking of the stitches and formation of blood clots.
There are also long-term complications that may occur, such as malnutrition due
to the decreased capacity of the intestine to absorb nutrients.
After the surgery, you need
to limit yourself to eating only ½ to 1 cup of food at a time—for the rest of
your life. You also will have to strictly limit sugar and fat, because eating
too much of these foods—candy and other desserts, chips, etc.—can cause you to
feel severe stomach cramping.
Because of the risk of
malnutrition after the surgery, you need to focus on eating healthy food, but
you also have to take nutritional supplements for the rest of your life. An
additional problem that many people experience after they lose a lot of weight
is sagging skin, which can cause serious chafing problems and infections. Many
people who have
bariatric surgery eventually feel the need for additional
surgery to treat this new problem.
As you can see, having
bariatric surgery is a serious decision. It requires major life changes and real
commitment to living your life a different way. Most bariatric surgeons believe
that patients should think of the operation as a last resort, only to be done
after other weight loss attempts have failed.
Who is a candidate?
The screening process to
identify who is a good candidate for the surgery varies from doctor to doctor,
but in general, most patients have to meet the following criteria to qualify:
- A body mass index (BMI)
of 35 to 40 with some of the complications of obesity, such as diabetes, high
blood pressure, sleep apnea and high cholesterol
- A BMI over 40 with no
complications of obesity
- Proof that you’ve tried
and failed to lose weight numerous times
Additionally, doctors
conduct the following types of screening
- Complete physical exam
and extensive lab workups
- Letter from your primary
care doctor giving you clearance to have the procedure
- Psychiatric screening to
make sure you are likely to be able to handle the major life changes the
surgery requires
- Psychiatric screening
for depression
- Commitment from you to
eat healthy foods in the right amounts and to exercise regularly
- Commitment from you to
participate in a support group before and after the surgery
- Commitment from you to
take the required nutritional supplements
- Commitment from your
spouse and other family members to support your efforts to lead a healthy
lifestyle
Bariatric surgery is a tool
that people have used to get them back on track to lead a healthy lifestyle.
It’s not a quick fix. But for people who have tried and failed to lose weight,
over and over again, the surgery offers a new option.
