Gut Transit Effect on Enterohepatic Circulation

Overview

A study to determine the influence of changing intestinal transit time of the enterohepatic recirculation of bile acids.

The digestion of food by human body starts from oral cavity and continues until its excreted as faeces. There are different factors affecting this process. Important factors are movement through the GI Tract, breakdown of food material and absorption by the body to produce energy. The unabsorbed waste material is then excreted by the body. Different enzymes are produced by human body which are responsible for digestion of food. One important chemical is bile which is produced in the gall bladder. It is important in digestion of fatty foods but affects the movement of food material as well. There are numerous bacteria present in human GI tract especially in mouth and large bowel which also play an important role in process of digestion of food. Different conditions of health and disease can affect how food moves through the GI tract (known as intestinal transit). It also affects the activity of different digestive enzymes and chemicals in body. The bacterial population in the body is also affected by changes described above. The purpose of this study is to observe how these different processes especially the intestinal transit, bile salts and gut bacteria affect each other. This will help to identify mechanisms responsible for different disorders of human gut like irritable bowel syndrome. The study is part of an effort to identify new and future treatment of these conditions.
