In the United States, around 15.5 million people suffer from severe obesity, according to the National Institutes of Health, and the numbers are increasing. Obesity increases the risks of morbidity and mortality because of the diseases and conditions that are commonly associated with it, such as type II diabetes, hypertension, and cardiovascular disease, among other health risks. Metabolic and bariatric surgical procedures have proven to be effective in the reduction of comorbid conditions related to severe obesity.*
Which Procedure is right for Me?
ADJUSTABLE GASTRIC BAND
LAPAROSCOPIC GASTRIC BYPASS
Adjustable gastric banding surgery involves the
placement of a silicone adjustable gastric band around
the top portion of your stomach. This procedure can
be reversed more easily than other weight loss
surgeries and is adjusted based on your progress and
your specific nutritional needs. Adjustable gastric
banding allows you to lose weight gradually by
reducing the amount of food you can intake.
Adjustable gastric banding is considered the least
invasive of all weight loss surgeries, as no cutting,
stapling or stomach re-routing is involved. When
completed laparoscopically, adjustable gastric band
patients experience less post-operative pain, reduced
hospital stays and increased recovery time.
Gastric laparoscopic bypass surgery, also referred
to as Roux- en-Y, is the most frequently
performed weight loss surgery in the United
States. Gastric bypass surgery works by changing
the anatomy of your digestive system. This
surgical weight loss procedure limits caloric intake
and also helps decrease some of the hormones
that stimulate appetite. Your bariatric surgeon will
create a small pouch at the top of the stomach
and then connect it to a portion of the small
intestine. Additionally, gastric bypass surgery
can be completed laparoscopically with smaller
incisions, less blood loss, fewer complications
and often, a quicker recovery.
By decreasing the stomach size and bypassing a
part of the intestines, gastric bypass surgery
induces faster weight loss. The remainder of the
stomach is not removed, but by bypassing it, it
can no longer act as a reservoir for excess food.
The gastric bypass procedure has demonstrated
added health benefits beyond weight loss as
many patients also experience lower blood
pressure, improvement in sleep apnea, acid
reflux disease, diabetes control and joint pain.

During sleeve gastrectomy surgery, your bariatric
surgeon will remove approximately 75 to 85
percent of your stomach, maintaining the
remainder of your digestive tract. Sleeve
gastrectomy procedures preserve the natural
continuity between the esophagus, stomach and
small intestine, so malabsorption of nutrients,
vitamins and minerals does not occur.
Sleeve gastrectomy surgery is performed
laparoscopically. Patients who have laparoscopic
gastric surgery typically experience reduced
hospital stays, smaller incisions, less scarring,
and often a quicker recovery than traditional
“open” procedures.
