Roux en Y Gastric Bypass Surgery: How it Works
Gastric
bypass surgery involves three main steps:
1. Creating a new, smaller stomach (gastric pouch) from the
existing stomach.
2. Bypassing 3 to 4 ft. of the small intestine (normally 20 ft.
long).
3. Connecting the bypassed digestive section to the lower
section of the small intestine, where necessary digestive juices
mix with food.
Post-Op Dietary Plan for Roux en Y Gastric Bypass Surgery
Patients
As with all surgical weight-loss programs, it is imperative that
Roux en Y patients adhere to dietary recommendations following
surgery. For the first 18 months after gastric bypass surgery,
patients must restrict themselves to consuming less than 800
calories per day; after 36 months, patients may consume no more
than 1200 calories each day. In addition, patients must avoid
eating sugars and fats to prevent "Dumping Syndrome."
Long-Term Weight-Loss Surgery Results with Roux en Y Gastric
Bypass
On average, patients who undergo Roux en Y gastric bypass
surgery experience a 70% loss of excess weight.
Gastric Bypass Surgery Gets Results
Roux en Y achieves significant weight loss in the following two
ways: by reducing the size of the stomach (effectively limiting
the amount of food that can be consumed by the patient), and by
creating a digestive "short cut" (achieving mild malabsorption
by reducing the amount of calories that can be absorbed by the
patient's digestive tract).
Upon successful completion of Roux en Y gastric bypass surgery,
patients benefit from smaller stomachs and less caloric
absorption. They eat less food, absorb fewer calories, and, as a
result, begin shedding excess pounds. |
