Oesophagitis, endoscope view. Inflamed oesophagus due to grade A oesophagitis (A is the least severe grade), as seen with narrow band imaging. Oesophagitis is usually caused by acid reflux, where stomach acids enter the lower oesophagus due to poor functioning of the muscle that closes off the entrance to the stomach. It causes heartburn (chest pain). The condition is made worse by smoking, drinking alcohol and obesity. Treatment is aimed at removing the causes. Antacid drugs, which reduce the acidity of the stomach juices, may also provide relief.
