Irritable bowel syndrome (IBS) is a chronic disease prevalent in today’s society and diet remains the most common aggravator of IBS symptoms. Existing literature suggest that IBS patients are dysbiotic as evidence indicates decreased levels of Bifidobacteria, Bacteroidetes and Faecalibacterium prausnitzii and increased levels of Firmicutes in comparison to healthy individuals. Studies suggest that changes in diet can modulate gut microbiota and therefore improve IBS symptoms. The two diets being investigated are the low FODMAP diet and the use of probiotics. A low FODMAP diet implements a reduction in the amount of poorly absorbed carbohydrates and probiotics are live microorganisms that have been proven beneficial when consumed appropriately. Based on the literature acquired from PubMed, a positive correlation appears to exist between the low FODMAP diet and IBS symptoms; 57% report symptom relief. There is also a notable effect on the gut microbiome after changing to low FODMAP diet, noted with a significant decrease in levels of Bifidobacterium, Clostridium, F. prausnitzii and Actinobacteria. This poses a concern as bacteria such as Bifidobacteria and F. prausnitzii are beneficial for health. When probiotics are taken amongst IBS patients a reduction in symptoms is also observed. Additionally, there is an increase in the abundance of Bifidobacterium and Lactobacilli. It is suggested that co-administration of probiotics with a low FODMAP diet may ensure beneficial levels of Bifidobacterium while IBS symptoms ameliorate.
