Irritable Bowel Syndrome (IBS) is a gastrointestinal disorder of growing interest, both in the United States and globally. In this thesis, I discuss and analyze various aspects of IBS, including the symptomology, potential causes and risk factors, the diagnosing process, and clinical manifestations. Further discussion includes current treatment and management plans for IBS. Fish oil supplements are also another area of growing interest in the medical field, and discussions about relevant findings regarding fish oil that indicate that it may be beneficial to patients suffering from IBS will be included. Finally, recommendations include a study to test whether fish oil supplements could serve as a potential treatment for IBS.
