Book excerpt: According to Dr. Mark Pimentel, Director of the Gastrointestinal Motility Program at Cedars-Sinai Medical Center, the majority of IBS cases can be treated successfully. Dr. Pimentel believes that the root cause of most IBS symtoms can be attributed to an overgrowth of bacteria in the small intestine. A New IBS Solution takes you through the historical evolution of conventional medicine's view on IBS in a way that can be easily understood. In addition, Dr. Pimentel presents a simple treatment protocol that will not only help you resolve your IBS symptoms, but will also prevent their recurrence.
