Bariatric Surgery: Drastic
Measures for Drastic Measurements
It used to be that “stomach
stapling” was a rare and extreme response to dangerous cases
of obesity.
But as more long-term data become available
about the generally positive outcomes for bariatric surgeries, more
consumers are opting for these procedures than for any other
non-cosmetic elective surgery.
With most of us normally so reluctant to go
under the knife, what’s driving the popularity of bariatric
procedures? Quite simply, as an investment in health, they offer a
very high return.
Follow-up research on patients of earlier
bariatric surgeries is showing that the prospects for long-term
weight loss are better than with any other mode of treatment for
seriously overweight people, those classified as “morbidly
obese.”
The data also show that post-operative health
outcomes for patients of bariatric surgery are remarkably good,
with major improvements in diabetes, cardio-vascular health,
musculoskeletal conditions and sleep disorders.
But perhaps the most important outcome shown is
that these health improvements are lasting, specifically because
patients of bariatric surgery have excellent chances of maintaining
a much lower, much healthier weight for years to come.
According to the Journal of the American Medical
Association, “bariatric
surgery offers the best treatment to produce sustained weight
loss in patients who are morbidly obese.”
That assessment has been borne out by the
statistics. The maximum weight loss is usually reached between 18
and 24 months after their surgery. The amount of weight lost tends
to vary a little between the various procedures, but on an average,
a loss of 60 percent of the excess weight was still maintained at
five years after the surgery.
One study of over 600 patients reported that an
average of 50 percent of the excess weight lost was still
maintained at 14 years after the surgery. The numbers for weight
loss maintenance in other treatment approaches come nowhere near
these rates.
Roughly speaking, the “morbidly
obese” are those defined as being 100 pounds overweight, or
with a body mass index (BMI) of 39 or more. A score of 35 or more
is used for those who already have associated health problems, such
as diabetes or heart disease.
Also referred to as “clinically severe
obesity,” it’s a condition that presently affects about
six million Americans. And for these people, the risks associated
with remaining overweight are simply much greater than the risks of
going under the knife.
People at lower BMIs typically are not
considered as candidates forbariatric
surgery bariatric surgery without extenuating
circumstances.
And sometimes people above a BMI of 40 are not
considered because of other factors. Certain psychological
conditions might preclude an individual’s candidacy, or an
inability to commit to lifestyle changes necessary for weight
maintenance.
For instance, people who consume lots of sweets
and high-fat junk foods and who don’t really plan to give
them up, won’t get the lasting improvements they want from
the surgery.
And there are some patients who have delicate
health complications such that they may have to lose weight in a
supervised program before undergoing the surgery.
With rates for complications below 2 percent and
mortality of less than one-half a percent, bariatrics surgeries
have proven, safety-wise, to be comparable to other elective
procedures, and far less risky than the heart bypass operations
that are so common today.
That’s a remarkably low incidence of
post-operative complications, particularly considering that the
general health in this patient population is highly compromised by
their excess weight to begin with.
Yet even as new techniques are developed that
improve the safety and efficacy of bariatric procedures—and
minimize some of their unpleasant side effects—experts worry
that the public will get the idea that these are routine surgeries
that offer a silver bullet solution to the problems of the gravely
obese.
Surgery is a complex and demanding procedure for
both the doctor and the patient, and like any surgery, it
shouldn’t be taken lightly. Mostbariatric surgery specialists
will not agree to perform a bariatric procedure on a patient who
hasn’t already demonstrated a concerted effort to get rid of
some of their excess through more conventional weight-loss
methods.
Surgical preparation usually includes weight
loss and conditioning for the patient immediately before the
operation, and then there is a lot of lifestyle and maintenance
work afterwards.
That’s the investment. The return? Early
death related to weight decreases markedly, and aside from the
other specific medical improvements, studies also show thatbariatric surgery patients get
improved mobility and stamina, better mood and self-esteem,
improvements in social interactivity and interpersonal
effectiveness. And for overall quality of life, that means a real
long-term gain.
Through Thick & Thin
Bariatric surgery is remarkably effective, but it’s no silver
bullet. Before seeking a bariatric surgeon, consider getting
counseling to help establish whether you have the commitment and
the support system in place to make the lifestyle changes
you’ll need to make the surgery successful over the long
haul.
