Scope
Aims, scope and focus
Digestion is published by S. Karger AG and is in Zone 4 of Medicine in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Helicobacter pylori-related gastroenterology studies, Gastrointestinal motility and disorders and Diverse Scientific and Economic Studies, together about 26.1% of its articles. (generated from OpenAlex topic counts and CAS ranking data)
Digestion concentrates on clinical research reports: in addition to editorials and reviews, the journal features sections on stomach/esophagus, bowel, neurogastroenterology, liver/bile, pancreas, metabolism/nutrition, and gastrointestinal oncology. Papers cover physiology in humans, metabolic studies, and clinical work on the etiology, diagnosis, and therapy of human diseases. It is thus especially cut out for gastroenterologists employed in hospitals and outpatient units. Moreover, the journal’s coverage of studies on the metabolism and effects of therapeutic drugs carries considerable value for clinicians and investigators beyond the immediate field of gastroenterology.
