Answer #1

e. pH level

Gastroesophageal reflux disease or GERD is a common example of a patholological change in pH level. It is a chronic condition that exhibits the stomach contents to rise up into the esophagus. The symptoms of this disease include heartburn, chest pain, wearing away of teeth, etc. Acid reflux results due to poor closure of the sphincter that is present between the esophagus and stomach. Since acidic pH is involved in this disease, esophageal pH monitoring is the method by which diagnosis happens in this disease.
