Helicobacter pylori Infection in Gastroesophageal Reflux Disease
Non-ulcer dyspepsia (NUD) is a symptom complex which is very common in patients presenting to the gastroenterologist [1, 2]. Several definitions of non-ulcer dyspepsia have been proposed over the years, but none has been definitively adopted [3–6]. A recent working party  defined NUD as a clinical syndrome including: upper abdominal or retrosternal pain, discomfort, heartburn, nausea, vomiting, or other symptoms considered to be referable to the proximal alimentary tract and lasting more than 4 weeks and for which no focal lesion or systemic disease is responsible.
