What is acid reflux? i have been diagnosed with acid reflux but rarely get heart burn. if i eat too much chili, spaghetti, or pizza, hours later i will have rythmic pain just under my rib cage that get progressively stronger and then i vomit 4 or 5 times.

This : This occurs because your stomach produces excess acid in response to certain foods. This can cause pain, bloating, and a burning feeling in stomach, chest, and esophagus. Associated belching and even vomiting can occur. The vomiting is your bodies way of trying to clear the excess acid when it backs up into the throat. On the other hand, there are other issues that could be going on (hiatal hernia, esophagitis, etc.) it is a good idea to request an endoscopy, which is a test where a camera is used to visualize your upper GI (gastrointestinal tract). This will give your doctors more information in able to formulate an appropriate treatment plan. All the best to you.

Acid : Acid taste specialy when bending over or after meals, pain behind the sternum and many other symptoms are caused by acid reflex. Your symptoms can also be caused by gall bladder disease. Please visit your primary health care provider for appropriate evaluation (abdominal us , barium swallow, upper gi).
