Gastric bypass surgery procedure in San Antonio

The gastric bypass procedure is considered to be the gold standard in weight loss surgery. First performed in 1968, the operation has evolved, but has stood the test of time. We now have more than 30 years of data on the tremendous success of this operation.

This weight loss surgery is done in two parts. The first part involves creating a very small new stomach (about an ounce) called the “pouch.” The pouch is the only part of your stomach that will ever “see” food again.
The second part of the procedure is the bypass. This is done by re-routing the intestines to carry food away from the pouch. A second connection is made to allow the digestive juices coming from the remaining stomach, liver and pancreas to meet with the food downstream.

The gastric bypass surgery procedure works by several different mechanisms. This is metabolic surgery that actually changes the way your metabolism works! The neurochemical pathways and hormones are altered in a favorable way that helps you lose weight rapidly, gives you better control of your blood sugars and decreases inflammation! The small pouch also forces you to eat less. You will feel full after eating only a few bites of food!

Gastric bypass surgery also causes a phenomenon known as dumping syndrome. This is usually brought on by consuming refined sugars or “sweets.” Dumping syndrome is a very uncomfortable feeling usually characterized by weakness, nausea, sweating and “just feeling really bad,” and it acts as a great side effect that helps patients deal with a major food trigger. Gastric bypass surgery is the ONLY operation that causes dumping syndrome.

Because of the re-routing of the intestines, the body may not get enough vitamins and minerals. It is important to take a multi-vitamin, calcium and vitamin B12 supplements for the rest of your life.




What to expect post-op with gastric bypass surgery

With a bypass, you should expect to stay in the hospital for one to two nights. Your immediate goals after surgery are to walk frequently and to do breathing exercises using a special tool called an incentive spirometer. In addition, we will give you some blood-thinning medication to prevent blood clots. Patients are usually allowed to begin sipping on liquids a few hours after surgery.

Post-op Day One goals: Transition completely from IV fluids and medications to oral intake and liquid pain medicine. We use a very special three-day local anesthetic to keep the incisions numb so most patients experience very little pain. Some patients can even go home today!

Day Two: Most patients are ready to go home today. Don’t feel bad if you are not quite up to it, though. We realize that everyone is different, and we want you to be completely comfortable before we let you go home.
