Adjunct Therapies to Standard Care for IBS and IBD Patients: Digestive Symptoms Improvement and Quality of Life Optimization.

The prevalence of both inflammatory bowel diseases (IBD) and Irritable Bowel Syndrome (IBS) is increasing, with persistent digestive symptoms, an altered quality of life, and higher rates of anxiety, chronic fatigue, and sleep trouble than the general population. This scoping review will analyze the latest clinical practice recommendations and clinical studies on non-pharmaceutical interventions such as diet adaptations, physical activity, cognitive behavioral therapies, and medical nutrition therapies such as probiotics, soluble fibers, chitin-glucan, and micronutrients for digestive symptoms relief, quality of life improvement and nutritional deficiencies correction in IBS and IBD patients. The objective is to help healthcare practitioners and dietitians to build personalized care program for IBD and IBS patients. Mediterranean diet, physical activity, cognitive behavioral therapies and medical nutrition therapies such as selected probiotics, soluble fibers, chitin glucan, peppermint oil and micronutrients are effective as adjunct therapies. These adjunct therapies may help to reduce persistent digestive symptoms, correct nutritional deficiencies and improve quality of life of IBS and IBD patients.
