Duodenal Bypass
Benefits and
Risks
The Advantages
of the Duodenal
Switch Weight Loss
Surgery Procedure
-
The more normal
stomach allows
for better
eating quality
but may
possibly result
in more
diarrhea and
foul smelling
bowel movements
and gas
-
No dumping
syndrome
because the
pylorus is
preserved
-
Minimizes the
chance of an
ulcer occurring
-
Very effective
for high BMI
patients
(BMI>55 kg/m2)
-
The intestinal
bypass is
partially
reversible for
those having
malabsorptive
complications
-
Laparoscopic
approach is
offered by some
surgeons
The
Disadvantages of the
Duodenal Switch
Weight Loss Surgery
Procedure
-
Greater chance
of chronic
diarrhea
-
Significant
malabsorption
leads to
anemia, protein
deficiency and
metabolic bone
disease in up
to 5% of
patients
-
More foul
smelling stools
and gas
-
Carbohydrates
can be well
absorbed and
lead to
inadequate
weight loss
-
This procedure
is the most
complex
surgical weight
loss procedure
and may yield
an unacceptable
level of
complications
in high risk
patients
(heart
failure, sleep
apnea)
