What’s burning inside?

Gastritis occurs due to changes in the soft skin lining the stomach. In 80 per cent of people, this is due to a micro-organism, bacteria, that inhabit the stomach lining and impair its natural mechanisms to prevent damage from acid. The acid, which is supposed to aid digestion of food in the stomach, damages the stomach wall in addition, leading to gastritis.

However, GORD is different. In GORD, the problem is backflow of acidic contents in the stomach to the gullet or the oesophagus. Acid should normally be present in the stomach for digestive purposes and the stomach lining has defensive mechanisms that protect the stomach wall from it. However, the oesophagus or the gullet is not similarly protected. The only mechanism that protects the gullet is the valve at the junction between the stomach and the gullet which is always closed, other than at times when food enters the stomach.
