Do you have gastro esophageal reflux or acidity also known? And do you have the need for antacids daily? This acid reflux is common named as heartburn. It means this is the pain you have in the chest and up the throat. GERD happens when the bile material, acid or food remains (pancreas juices) go up the esophagus. The acid climbs up the esophagus and inflames it, makes irritations and scars too. This can damage the esophagus and shrink it even. It becomes hoarse, burning, you cough, have nausea, eroded teeth, asthma and wheezing too. And all this makes you at risk for esophagus cancer.
