IMPORTANT SAFETY INFORMATION
Bariatric Surgery is used in morbidly obese adult patients for significant
long-term weight loss. It may not be right for individuals with certain
digestive tract conditions. All surgery presents risks. Weight, age, and
medical history determine your specific risks. Ask your doctor if bariatric
surgery is right for you.
Adjustable Gastric Band
The Band* wraps around the upper part of the stomach, dividing the stomach
into a small upper pouch that holds about 1/2 cup food and a larger lower
stomach. By creating a smaller stomach pouch, the Band* limits the amount
of food that can be eaten at one time, so you feel full sooner and stay
full longer. It does not significantly affect normal digestion and absorption.
Food passes through the digestive tract in the usual order, allowing it
to be fully absorbed in the body. Gastric band patients have been shown
to lose 41% of their excess at 3 years.
During the sleeve gastrectomy procedure, a thin vertical sleeve of stomach
is created using a stapling device. The sleeve is about the size of a
banana, the rest of the stomach is removed. By creating a smaller stomach
pouch, a sleeve gastrectomy limits the amount of food that can be eaten
at one time, so you can feel full sooner and stay full longer. Sleeve
gastrectomypatients have been shown to lose an average of 66% of their
Roux En Y Gastric Bypass
The surgeon creates a small stomach pouch and attaches a section of the
small intestine directly to the pouch. This allows food to bypass a portion
the small intestine, limiting the amount of food that can be eaten at
one time, so you feel full sooner and stay full longer. By bypassing a
portion of he small intestine, your body also absorbs fewer calories.
Complete resolution or improvement of some of the obesity-related health
problems, including type 2 diabetes, high lipid (fat) levels, high blood
pressure, and obstructive sleep apnea are common. Gastric Bypass patients
are shown to lose up to 75% of excess body weight on average.
