The digestive system is the group of organs that break down food so your body can absorb its nutrients. Everything in your body needs these nutrients from the digestive process to work correctly. Digestive diseases are disorders of the digestive tract, which is also called the gastrointestinal (GI) tract.      

Gastroenterology (GI) is the branch of medicine dedicated to treating diseases and conditions affecting the gastrointestinal or digestive system. Gastroenterologists, also known as "GI doctors" are experts on the digestive system and how it works.
