Gastric bypass Roux-En-Y is currently the number one gastric bypass surgery performed. The operation requires the creation of a small gastric pouch for food in the top portion of the stomach and a small piece of the small intestine, resulting in most of the stomach and part of the intestine being "bypassed" as the food is digested.
The purpose of this surgery is to greatly reduce the quantity of food and drink that can be ingested and, as the surgery now bypasses part of the intestine the amount of nutrients absorbed from the food ingested is also limited. Consequently, patients undergoing this procedure are forced to make significant, permanent changes to the way they eat.
After the operation
After the operation, the patient will only be able to eat about 50 grams of food at a sitting. Eating more than this will probably make them sick and induce vomiting. This can also happen if they try to eat too quickly. "Dumping" (symptoms dizziness, nausea, cramping, and sweating) is another problem that may be experienced if the patient tries to eat too much sugar. It is also critical that the patient chews his food carefully and completely to avoid clogging. The patent will also only be able to drink a small amount at a time . So, to avoid dehydration, the patient needs to carry water with them all the time and take small sips throughout the day.
The portion of the intestine bypassed is one of the primary areas for the absorption of calcium and iron, so vitamin and mineral supplements will be required. Also for the first few months after surgery, the patient will need to drink protein powder shakes to compensate for the lower protein absorbed. In addition, the patient will require either a monthly vitamin B-12 injection or a daily vitamin B-12 tablet for the rest of his or her life, as the modifications to the stomach and intestines won't allow for the sufficient uptake of this essential vitamin from the food ingested.
Gastric bypass RNY is not a magic solution or quick fix. This process, like any weight loss strategy, requires strong commitment and patience to be effective. If you can't follow the rules and make the required lifestyle changes then don't have the surgery. If you are willing to commit to the life changes required to achieve and maintain a healthy weight and lifestyle, then this may be a suitable procedure to get you started in the right direction with respect to your weight loss.
