Chronic, progressive, immune-mediated illnesses of the digestive tract are referred to as "Inflammatory Bowel Diseases" (IBDs). IBDs mostly fall into two subtypes: Chron's Disease (CD) and Ulcerative Colitis (UC). Although the exact cause of many disorders is yet unknown, genetic, environmental, and host-related variables all play a role in their development. In terms of managing symptoms, preventing relapses, and taking care of the pathology, recent evidence has demonstrated that food therapy is the cornerstone of IBD treatment. IBD patients demonstrate how nutrition, particularly dietary fibre, may influence the makeup of the microbiome. These patients are lacking in micronutrients and are more susceptible than the general population to energy protein deficiency. There is now no known dietary component thought to be the cause of IBD, nor is there a known treatment diet for it. This review's objective is to assess how dietary fibres affect CD and UC and to aid medical practitioners in managing these diseases' nutritional needs. To better patients' psychosocial situations and quality of life and to advise the right amount and kind of fibre in the case of IBD, more research is required.
