Small amounts are released through the antrum of the stomach, which goes through the duodenum and proximal jejunum. Various substances stimulate secretion of gut hormones and enzymes. In gastric bypass operations, the antrum, duodenum and proximal jejunum are bypassed and reduce levels of these hormones. ...Read more

You just need to go to an experienced surgeon that does revisional bypass surgery. ...Read more

Diverts food from lower stomach and duodenum (helps with diabetes). Must eat appropriately. Solid food, no sipping with food, no sweets, no bad snacks. Most lose 80% of excess weight at one year. Then some bounce back with total loss at 5-7 years of 70% excess wt. ...Read more

How are lap band and gastric bypass surgery different?

How are lap band and gastric bypass surgery different?

Malabsorption: The lap band is a device placed to make the stomach seem smaller thus allowing you to eat less and feel satisfied. With the bypass, a surgeon creates a smaller stomach by cutting which has a similar effect. Additionally, the intestines are cut and rerouted so that the upper segment is "bypassed". This decreases the absorption of food which leads to faster and relatively easier weight loss. ...Read more
