Acid reflux surgery is done to repair the root cause of acid reflux: a weak stomach valve.
The procedure is called a "Nissen Fundoplication". Your doctor pulls your stomach down and restores structural support for your stomach valve. The goal is to repair the valve-mechanism that lets food enter your stomach, but prevents acid to escape.
If you have a hiatal hernia, which is an upward bulging of your stomach, your surgeon pulls it back down. He wraps the upper part of your stomach around your esophagus to prevent it from popping back into your chest.
In most cases, surgery is the last choice of treatment. If other options such as acid reflux remedies, medications and life style changes don't prove to be successful, you can consider acid reflux surgery.
Some surgeons claim that surgery can be a first choice of treatment, because it prevents you from taking pills for the rest of your life.
Numbers show that patients improve with acid reflux surgery:
Acid reflux is caused by a weak stomach valve ànd overpressure in your intestines. Surgery can become completely effective if you change your diet to stop small intestine bacterial overgrowth.
Surgery always includes a certain risk and no matter how good your surgeon is, you never have a 100 percent guarantee of success.
You can consider an operation if you have severe acid reflux after trying all remedies for acid reflux.
