Atlanta Gastroenterology Associates (AGA) is a medical practice focused on gastroenterology and based in Atlanta, Georgia. Now part of United Digestive, it is described as one of the largest gastroenterology practices in the country and has served Georgia and the southeastern United States for more than four decades. The organization has grown from two physicians to more than 90 and operates more than 50 locations across metro Atlanta, the north Georgia mountains, and Athens. It runs several accredited endoscopy centers where outpatient gastrointestinal procedures are performed, and its physicians have privileges at most local hospitals.

United Digestive positions itself as a physician services organization that partners with gastroenterology practices nationwide, providing operational support, regulatory resources, and assistance with revenue cycle and managed care so physicians can focus on patient care. In 2026, AGA expanded its Forsyth County location to broaden access by increasing clinic hours.
