Procedure of the surgery
In addition, the Roux En Y Bypass technique sews a loop of small intestine to the fore stomach so that the food bypasses part of the small intestine and thus additionally absorbs fewer nutrients from the food. So that despite the bypass of the duodenum the digestive juices come to the food, a further small intestine loop must be sewn on, which supplies the digestive juices approximately 1-1.5 m after the other loop. This loop then leads from the 12 finger intestine (which is actually the continuation of the stomach) to the other loop.
Thus this technique deliberately leads to a poor absorption (malabsorption) of the food. Thus, the Roux En Y Bypass technique leads to a faster and greater weight loss than purely restrictive procedures such as the gastric band. About four weeks after the operation, patients can eat solid food again.
Patients usually report nausea after eating sweets, this is explained by the disturbed digestive tract. Also with this technique, vitamin B12, minerals and protein must be supplemented for life after the operation.
