Introduction To Gastrointestinal Conditions

An Introduction To All Gastrointestinal (GI) System Conditions

The gastrointestinal system is one of the largest and most complicated systems that exists in the human body. One classically views the gastrointestinal system as a long hollow organ twisting its way from mouth to anus partitioning into the esophagus, stomach, small intestine and large intestine otherwise known as colon. The solid organs that support digestion include the liver, gallbladder and pancreas which not only supplement digestive juices but provide a myriad of other functions. Fundamentally, the gastrointestinal system is a collection of organs designed to breakdown food into smaller absorbable nutrients including carbohydrates, proteins, fats and their accompanying vitamins, elements and minerals. The esophagus acts as a conduit to the stomach and when food reaches the stomach it is churned and partially digested into chyme. A fraction of the stored chyme is then carefully emptied into the small intestine at precise amounts. The majority of digestion and absorption occurs in the small intestine which at length reaches 25 feet and when stretched out occupies a surface area the size of a tennis court! The end of the digestive tract which includes the colon reaching 5 feet in length provides the body a means of reabsorbing water and releasing non-absorbable food and waste through stool.


Research the last few decades has revealed that an intricate system of bacteria, nerves and hormones work in unison to control digestion and maintain the body’s balance of water and electrolytes. In fact, there are more bacteria in our gut than there are human cells! Within the approximately one hundred trillion bacteria that occupy the gastrointestinal lumen is a balance of good versus bad – hence the emerging use of prebiotics, probiotics and antibiotics. Similar in complexity to our gut flora is the gastrointestinal nervous system which equals in number the amount of nerves found in the spinal cord! As our understanding of the innervation of the gastrointestinal system unfolds novel medications have been designed to alter motility, secretion and overall sensation. Hormones complement bacteria and nerves in regulating the gastrointestinal system. Hormones act as the conductors for the symphony of digestion. Unfortunately, the types and their action are not completely known but as we tease out their function our understanding of appetite, satiety and obesity will become more clear and provide an avenue for future treatments.
