There are two main types of bariatric surgery that help with weight loss in different ways:
Catholic Health performs gastric bypass surgery, lap banding surgery, and vertical sleeve gastrectomy.
In this procedure, the stomach is permanently divided into two. The top part becomes the newly created and smaller stomach, and the rest is closed and remains in place. This portion now becomes the bypassed portion of the stomach; it will not receive what is eaten, but it will continue to assist with digestion by producing gastric acid and other digestive juices.
The “new” smaller stomach is connected directly to the middle portion of the small intestine (jejunum), thus bypassing the rest of the stomach and the upper portion of the small intestine (duodenum).
Gastric bypass causes weight loss for two reasons:
Weight loss occurs more quickly after gastric bypass than after purely restrictive procedures, but it also is considered a more invasive procedure.
Life-long follow up and strict adherence to the dietary guidelines set by your doctor and nutritionist are critical to a healthy and successful outcome.
This non-invasive, restrictive and reversible procedure places a hollow, silicone ring, or band, around the main portion of the stomach, and a port is secured under the skin of the abdomen.
The band creates a small passageway between the uppermost part and the rest of the stomach. This narrow passageway restricts the amount of food required to feel "full," so less is eaten, which promotes weight loss.
The degree of stomach restriction is controlled by the amount of fluid in the band. Band fluid is adjusted with the injection or removal of fluid through the port. Both the band and the port remain in place until surgically removed.
Patients can expect regular office appointments, as adjustments to band tightness may be needed. Regular follow-up is mandatory and supplementation is commonly needed for as long as the band is present.
Vertical sleeve gastrectomy is a purely restrictive and irreversible procedure in which approximately 85% of the stomach is removed, creating a slim banana or tubular shaped stomach.
Although normal functions of the stomach are preserved, weight is lost because the amount of food that can be consumed is drastically reduced helping you feel fuller faster.
