What is the primary focus of gastroenterology?

Gastroenterology is primarily concerned with the digestive system, which encompasses the organs involved in the process of digestion, absorption of nutrients, and elimination of waste. This field encompasses a wide range of functions and disorders related to the gastrointestinal tract, including the esophagus, stomach, intestines, liver, pancreas, and gallbladder. Gastroenterologists are specialists who diagnose and treat conditions such as ulcers, irritable bowel syndrome, liver diseases, and colorectal cancer, among others. Such a broad focus on the entire digestive tract distinguishes gastroenterology from other fields that concentrate on specific organs or systems, such as hepatology, which focuses solely on the liver. Understanding gastroenterology through its primary focus helps in appreciating the complexity and importance of the digestive system in overall health.
