The first cause of heartburn is attributed the contents of the stomach backing back into the esophagus. This is attributed to weak esophagus muscles that fail to close tightly. If you have this condition repeated for over two weeks, then you should seek medical advice. The likelihood that you could be suffering from gastroesophageal reflex disease, also known as GERD, is a possibility. This is a medical condition that manifests itself with the individual basically tasting the contents of the stomach at the back of their mouth. Also on account of the fact that the contents of the stomach go back to the esophagus one might feel a burning sensation in the chest region. This is a condition that must be immediately arrested. A delayed intervention will result in the long term use of medication to neuter the acid. In the worst case scenario, a prolonged episode of heartburn might require the individual to go for surgery to intervene in this situation.
Another factor that can cause heartburn is a medical condition referred to as Hiatal Hernia. This is a medical condition where the stomach is pushed upwards through the diaphragm and into the chest. The natural bent of such an episode is that the pressure continues been exerted upwards, and this could possibly cause the muscles at the base of the esophagus to open up. The corollary is that a portion of the stomachs contents are then opened up and this leads to hearburn.
