Gastroenterology is the branch of medicine focused on the digestive system and its disorders. The digestive system functions to move material through the gastrointestinal (GI) tract via peristalsis, break down that material via digestion, absorb nutrients for use throughout the body, and remove waste from the body via defecation. We realize the disorder in digestive system can affect to many aspects especially patients’ quality of life, Eisai committed to taking part in the latest therapeutic development for gastroenterology.
