Approaches to Weight Loss Surgery
Please note: A brief explanation is provided below. For more details, including
risks and additional benefits of surgery, please contact your physician.
The Roux-en-y Gastric Bypass (pictured on the left) is a combination malabsorptive/
restrictive procedure. The surgeon attaches the patient’s small
intestine directly to a pouch that has been surgically created in the
stomach. Food bypasses part of the small intestine, which reduces the
body’s absorption of calories and nutrients without interfering
with digestion. Patients may experience about 60 to 70% of excess body
weight loss, most within a year.
In Gastric Banding surgery, a silicone band is inserted around the upper
portion of the stomach to create a “pouch” which can hold
about two ounces of food. The type of surgery is most often done through
small incisions (laparoscopically) and is referred to as the Lap-band
procedure. The band may be removed but it is designed to remain permanently.
This procedure generates weight loss solely through gastric restriction
(reduced stomach volume). The stomach is restricted by stapling and dividing
it vertically and removing more than 85% of it. This part of the procedure
is not reversible. The stomach that remains is shaped like a very slim
banana and measures from 1-5 ounces. The nerves to the stomach and the
outlet valve (pylorus) remain intact with the idea of preserving the functions
of the stomach while drastically reducing the volume.
For best results following surgery, patients are advised to:
- Eat less
- Eat slowly
- Chew well
- Avoid drinking fluids shortly before, after and during meals
- Regularly exercise
- Participate in support groups
