Acidity
Acidity is related to heartburn and gas formation in stomach. In acidity, acid reflux or gastroesopohageal reflux disease, or more commonly known as urdhva gata amalpitta in ayurveda, there is a movement of gastric juices (carrying acid) from the stomach into the lower esophagus (food pipe). This is a condition which is caused when acidic contents in stomach (hydrochloric acid) move upward into the esophagus and making it dysfunctional.
