Peptic ulcers come about when acid from the digestive tract erodes, or eats away at, the inner layer of the esophagus, stomach or small intestine.  This constant wearing away of the inner digestive lining creates open sores that over time cause pain, nausea and other symptoms over time.   Currently, about 1 in 10 Americans experiences gastric ulcers at some point in their lives.  Depending on the location of the developing ulcer, whether in the esophagus, stomach, or upper portion of your small intestine, complications can arise over time.
