Acid reflux ( referred to by doctors as Gastro-oesophageal reflux) is a condition where the lower oesophageal sphincter is abnormally relaxed and allows the stomach's acidic contents to reflux (flow back) into the gullet (oesophagus). Symptoms of acid reflux disease or heartburn include:
- A painful or burning sensation in the upper abdomen or chest, sometimes also radiating to the back (commonly mistaken for symptoms of a heart attack as pain can be severe).
- bad or sour taste if acid reaches mouth and throat
- In serious cases some patients report difficulties breathing because the acid reflux irritates the throat and respiratory tract.
- Lots of belching and burping!
