In this review, pharmaceutical treatment options are unaccounted for. Consensus groups and meta-analyses have designed guidelines that are similar, with variations in the strength of recommendations and some cultural and geographical particularities. IBS-C diagnosis relies on clinical criteria like the Rome IV criteria, and treatment typically begins with dietary changes.
Studies show that a diet with FODMAPs affects bloating, abdominal pain, and other IBS symptoms, thus, the low FODMAP diet, as well as the modified National Institute of Clinical Excellence (NICE) diet, can offer symptom relief by reducing fermentable carbohydrates that cause bloating and discomfort. While gluten- and lactose-free diets are sometimes tried, evidence for their effectiveness in IBS is limited. Overall, individualized dietary and lifestyle interventions remain central to managing IBS symptoms.
