Overview
The current understanding of the pathogenesis of dyspepsia began with the first description of gastric ulcer disease in 1799. The term was first used in its current form in 1916 by Walter Alvarez.
Historical Perspective
- Indigestion is an old english word meaning ‘lack of digestion’, and the symptoms of dyspepsia have known since the birth of medicine. However, the underlying pathogenesis of dyspepsia only began to be understood when Baillie in 1799 first described the pathology and symptoms of gastric ulcer disease.

- Walter Alvarez at the Mayo Clinic in Rochester, MN was the first to apply the term 'functional dyspepsia' in 1916 to describe patients with ulcer-like symptoms and a normal X-ray.
- In pre-16th century:
- Hippocrates gave a detailed describtion of the symptoms of peptic ulcer disease
- Avicenna described the relationship between abdominal pain and mealtimes in peptic ulcer patients[1]
- In 1586, Marcellus Donatus of Mantua described gastric ulcers by performing autopsies
