Question: what is the difference between dyspepsia and functional dyspepsia?
Answer: Dyspepsia is the most common upper gastrointestinal (GI) symptom, and it includes epigastric pain, fullness, discomfort, burning, early satiety, nausea, vomiting and belching. Functional dyspepsia (FD) is diagnosed when upper GI endoscopy reveals no organic lesions that might explain the dyspeptic symptoms.
