What does “gastro” refer to?

The prefix “gastro-” refers to the stomach and, more broadly, the digestive system. It is derived from the Greek word gaster, meaning stomach. Medical terms like gastroenterology (the study of the digestive tract) and gastritis (inflammation of the stomach lining) use this prefix. The gastrointestinal (GI) system includes organs such as the stomach, intestines, liver, and pancreas, all of which play vital roles in digesting food and absorbing nutrients. Maintaining gastrointestinal health involves balanced eating, hydration, fiber intake, and avoiding excessive alcohol or processed foods. Digestive disorders can affect nutrient absorption and overall wellness.
