Functional dyspepsia, also known as indigestion, is the term used to describe symptoms of the gastrointestinal tract caused by improper digestion of foods. Functional dyspepsia is also called non-ulcer stomach pain or non-ulcer dyspepsia. Functional dyspepsia is a common, long-recognized condition with a number of upper abdominal symptoms. Although diagnosing this condition can sometimes be challenging, due to the variable nature of symptoms, the prognosis for functional dyspepsia is good. There is no evidence that it leads to cancer or another serious disease.
