<p>Acidity is quite a common condition; in fact it is so common that most of us have experienced it in our lives. Though acidity is quite common, not many people know the actual reason why it happens. A ring of muscle called the lower esophageal sphincter acts as a valve at the entry of your stomach. Usually it closes as soon as a person consumes food, however, if there is a problem in it closing or if it opens up too often then the acid produced in the stomach moves up to the oesophagus causing a burning sensation known as acidity. If acidity occurs more than twice a week then it might indicate gastroesophageal reflux disease (GERD). If you suffer from acidity regularly then getting an Acidity Test is the best way to check if you suffer from GERD or if there is some other reason for it. While normally acidity is easily diagnosable and a person suffering from it can identify it easily, an acidity Test in Gurgaon usually includes other tests to check for impact as well as other underlying causes. The phlebotomist takes your blood sample, which takes only a few minutes. The sample is then sent to the lab to perform the tests included in an Acidity Test package.</p>
