This new understanding of the gastrointestinal tract, enteric nervous system, and the central nervous system has provided more holistic treatment options for those suffering from digestive disorders, such as IBS. Irritable Bowel Syndrome, or IBS, is one of the most common functional digestive disorders and plagues much of the United States population. It is characterized by a cluster of symptoms such as abdominal pain, bloating, diarrhea, constipation, and other digestive issues. It’s so broad range that the impact of IBS ranges from a mere inconvenience to a severe disability. Reports estimate that between 38-96 million Americans suffer from IBS in their lifetime, yet only 5-7% of them receive the proper diagnosis. This is unacceptable, disheartening, and preventable. With this growing body of gut-brain research, there are stronger possibilities for treatment, cure, and maintenance of many GI disorders, including IBS, with the help of functional medicine.
