Core Fighting Gut and Liver Disease logo


CORE is the research charity of the British society of Gastroenterology.

Digestive diseases are conditions that affect the gut, liver and pancreas. Collectively they are a factor in 1 in 8 deaths in the UK – and more than a quarter of cancer deaths are from cancers found in the digestive system. Core supports medical research to save lives. By increasing our understanding of disease we can diagnose earlier and provide more effective treatment. To enable patients to take control of their conditions, Core provides evidence-based information. And we want to make sure that nobody suffers through ignorance or embarrassment so we work to raise awareness of digestive diseases, their symptoms and impact.
