Effects on the Gastrointestinal System

The importance of effective liver function for overall health, and proper gastrointestinal function in particular, is rarely emphasized in health discussions in the United States. One reason might be that there is neither laboratory evidence nor specific physical symptoms to reveal an overburdened liver in the beginning stages. The symptoms may be nonspecific, such as general malaise, fatigue, headache, epigastric pain, bloating, nausea, or constipation. Discomfort following meals and intolerance of fat are also notable indications of disturbances in the biliary system.
