There may be the several causes of Acid Reflux, but the most usual cause of GERD is the increase in acidity or gastric acid production in the body. It may also because of:

• Obesity
• Pregnancy
• Tight-fitting apparels
• Yeast infections is also thought to be one of the causes of GERD at times

Further an added ironical cause of the disease is normally, the insufficient production of stomach acid in the body. Actually, the valve, the hollow organ with a flap that insure the one-way course of fluid through the organ, once emptied triggers acidity in the intestines. If the valve fails to open, the contents of the stomach will be blended into the esophagus, and then irritation occurs.
