DEAR DOCTOR K: My doctor says I have "functional dyspepsia." Medications haven't helped. Could something more serious be wrong?
DEAR READER: Dyspepsia is a medical term for persistent upper abdominal pain or discomfort. When doctors use the word "functional," they mean that there is no identifiable cause for the problem. By this definition, the majority of people with dyspepsia may have functional dyspepsia.
