A major cause of discomfort that I frequently see in my clinic is heartburn. Also known as GORD (Gastro Oesophageal Reflux Disorder – or the US version GERD), reflux is the result of stomach acids entering the oesophagus and burning the delicate tissue. Our stomach is protected from the acid due to a special mucosal lining, however, the oesophagus is not so protected. While there are numerous reasons for reflux, medical treatments lower stomach acid levels. These medications are known as Proton Pump Inhibitors (PPIs). Although this may appear to be a solution, it causes more damage than often acknowledged. You can read more about the dangers of taking PPIs at http://articles.mercola.com/sites/articles/archive/2010/06/05/natural-ways-to-relieve-heartburn-symptoms.aspx
If you have any problems with reflux, I strongly recommend you seek appropriate treatment as, if left untreated, can cause severe damage to your oesophagus (including oesophageal cancer). As with all health conditions, you must address the underlying cause of the reflux to achieve lasting results.
