Digestive health refers to the overall well-being and functioning of the digestive system, which includes the stomach, intestines, liver, and gallbladder. Research in this area focuses on understanding and improving the health of the digestive system, including studying the causes and treatment of conditions such as irritable bowel syndrome, Crohn's disease, and gastroesophageal reflux disease. This research often involves examining the role of diet, lifestyle factors, gut microbiota, and genetics in maintaining digestive health. Additionally, researchers may explore interventions such as probiotics, prebiotics, and dietary supplements to promote digestive health and prevent digestive disorders.
