Acidity is characterized by the increased secretion of acid in the stomach that causes pain and burning sensation in the middle of chest after the intake of meal. It consists of the feeling of heartburn that is felt in the area of the lower part of the chest. This is caused by the backflow of stomach acid into the esophagus. Many people are completely unaware that this occurs because of habits and lifestyle choices that are very unhealthy.
What happens is that the gastric glands end up generating too much acid than is needed to help in digestion. The consequence is the burning feel that seems to come from just upwards of the stomach or just downwards of the breastbone.
In common tongue, this condition is called ‘heartburn’. It might also be understood as ‘acid indigestion’. In more scientific spheres, acidity is called acid reflux, gastroesophageal reflux (GERD), and acid reflux.
Nevertheless, it is fairly common to experience an occasional heartburn. This type could be relieved by simple antacids.
