Core Tip

In the following eight articles we have provided an overview of the current research and epidemiology of two leading chronic gastrointestinal conditions that affect populations across the globe. The challenges of accurately diagnosing irritable bowel syndrome (IBS) are covered and the pathophysiology of constipation is thoroughly explored. Both standard and innovation strategies for the treatment of IBS are discussed, including 5-HT4 antagonists, surgery and the use of probiotics. Inflammatory bowel disease (IBD) encompasses several multifactorial conditions including Crohn's disease, ulcerative colitis and pouchitis. An alarming link between IBD and colorectal cancer has been made, which heightens the importance of preventive colonoscopic screening. Treatment for IBD may involve immunomodulators, biologic agents and surgery. Technologic advances that increase the detection of etiologic agents for IBD are being developed and may help in the development of better therapeutic strategies for these complex conditions. I hope these articles will inspire clinicians and researchers to focus their efforts on preventing the development of these conditions before irreversible damage occurs and the difficult job of treating these patients is required.
