The Roux en Y Gastric Bypass (“RYGB”)
The Roux en Y Gastric Bypass (“RYGB”) is a surgical procedure that
significantly reduces the amount of food that can be eaten at one
time and somewhat reduces the amount of calories and nutrients the
body absorbs. The lower portion of the stomach and first segment of
the small intestine (Duodenum) are bypassed.
Food entering the new small stomach (pouch) causes a sensation of
fullness, and then slowly empties into the jejunum(middle segment
of the small intestine) through the “new” small outlet. This
re-routing causes food to bypass the lower part of the stomach and
duodenum. Digestive juices from the lower stomach and duodenum
flow to mix with food lower down the intestinal track, thus
permitting the digestion of food.

Other Options:
Restrictive Banding
Duodenal Switch
With the new arrangement of stomach and intestine, gastric contents
enter the jejunum directly after leaving the stomach pouch. When
concentrated sweets are ingested, the patient may experience
symptoms known as the “dumping syndrome”. This syndrome is
characterized by gastrointestinal symptoms of gastric fullness,
nausea, abdominal cramping and diarrhea, as well as, flushing,
sweating, weakness, rapid heartbeat, and tiredness. The effects of
the syndrome will pass in about 45 minutes. This syndrome is a
tool – discouraging the patient from eating too fast and making
poor food choices.
