Gastrointestinal System

The gastrointestinal (G.I.) system consists of the esophagus, the stomach, the small intestine, the large intestine or colon, the liver, gallbladder, and the pancreas. Generally, the physiological changes of an aging digestive system are minor. With this in mind, it is important to recognize and actively treat most new G.I. problems in healthy older people, rather than ascribing symptoms to aging. The following section reviews some of the most common changes among older adults that can affect the functioning of the G.I. system.
