“Irritable Bowel Syndrome (IBS)” is a prevailing functional gastrointestinal disorder indicated by bloating, recurrent stomach pain, and altered bowel habits [1]. It affects approximately 10-15% of the global populace, imposing a sizable burden on healthcare and impairing patients' QoL [2]. Despite its high prevalence and clinical significance, the pathophysiology of IBS remains incompletely understood, likely involving a composite interaction of genetic, environmental, as well as psychosocial factors [3].

Among the various factors implicated in IBS pathogenesis, dietary factors have garnered considerable attention in recent years [4]. Emerging evidence suggests that certain dietary components, such as “Fermentable Carbohydrates (FODMAPs)”, gluten, and food additives, may exacerbate IBS symptoms in susceptible individuals [5]. Conversely, dietary modifications, including the adoption of gluten-free diet, low FODMAP diet, and elimination diets, have shown promise in alleviating symptoms and improving QoL in IBS Subjects [6].

Despite growing interest in dietary interventions for IBS management, there remains a need for comprehensive evaluation of their efficacy and safety. This research intends to acknowledge this gap by conducting research, and this research seeks to provide constructive insights into the role of dietary interventions in optimizing IBS management and guiding clinical practice.

This prospective research was directed at a tertiary care to estimate the efficacy of dietary interventions in managing IBS symptoms and improving QoL. Subjects diagnosed with IBS corresponding to Rome IV standards were recruited from the gastroenterology outpatient department between 2020-2022. Inclusion criteria comprised adult Subjects (aged 18-65 years) with a confirmed diagnosis of IBS and willingness to comply with dietary interventions. Subjects with organic gastrointestinal diseases, significant comorbidities, or contraindications to dietary modifications were excluded.

Baseline demographic and clinical data, including age, gender, IBS subtype, symptom severity, and medication use, were collected. Dietary involvements, including gluten-free diet, low FODMAP diet, and elimination diets, were tailored to individual patient preferences and symptom profiles. Subjects were ensued regularly for a minimum of 6 months to assess treatment response and adherence. Outcome measures included changes in IBS symptom severity scores, QoL assessments, and adverse events related to dietary modifications. Statistical analysis was performed using appropriate tests, as applicable.

Research subjects' baseline attributes were examined. Females outnumbered males (55%), and the mean age was 38.5 years. D Subtype occurred 40% of the time, followed by IBS Subtypes C (30%), M (20%), and U (10%). The mean symptom severity score was 7.2 ± 1.5 at baseline. Table 1

Table 2: Effect of Dietary Interventions on IBS Symptoms and QoL

Table 2 shows how nutrition affects IBS symptoms and QoL. Significant reductions in symptom severity were seen after implementing gluten-free, low FODMAP, and elimination diets (p < .05). The low FODMAP diet showed the greatest reduction in symptom severity (mean change: -3.5 points; 95% CI: -4.2, -2.8; p < .001), followed by the elimination diet (-2.8 points; 95% CI: -3.5, -2.1; p < .001) and gluten-free diet (-2.0 points; 95% CI: -2.8, -1.2; p = .002).

IBS is a complex gastrointestinal disorder described by a wide scale of symptoms, comprising bloating, stomach pain, and altered bowel habits. Despite its high prevalence and significant effect on QoL, effective management strategies remain elusive. Dietary interventions have emerged as promising therapeutic options, aiming to alleviate symptoms and improve Subjects' overall well-being. In this discussion, this research will explore the implications of current research findings, compare them with existing literature, and discuss their clinical relevance.

The results of current research demonstrate significant improvements in IBS symptoms and QoL subsequent to dietary interventions. Specifically, all three dietary approaches - gluten-free diet, low FODMAP diet, and elimination diet-led to notable reductions in symptom severity scores compared to baseline. These findings corroborate previous research highlighting the efficacy of dietary modifications in managing IBS symptoms [1,2].

Among the dietary interventions evaluated, the low FODMAP diet emerged as the most effective in symptom reduction. This finding is consistent with existing evidence suggesting the role of FODMAPs in triggering gastrointestinal symptoms in susceptible individuals [3]. By restricting the intake of high FODMAP foods, such as certain vegetables, fruits, and grains, the low FODMAP diet aims to minimize fermentable substrate availability in the gut, thereby reducing symptoms connected with bacterial fermentation and gas production [4]. current research adds to the growing body of literature supporting the effectiveness of the low FODMAP diet as a first-line dietary treatment for IBS management.

While the low FODMAP diet yielded the most pronounced symptom relief, it is essential to acknowledge potential limitations and challenges linked with its implementation. Firstly, the restrictive nature of the low FODMAP diet may pose practical difficulties for Subjects, as it requires careful planning and monitoring of food choices to ensure nutritional adequacy [5]. Moreover, longstanding adherence to the low FODMAP diet may lead to alterations in the gut microbiota composition and nutrient intake, raising concerns about its sustainability and potential adverse effects on gut health [6]. Therefore, healthcare providers should provide comprehensive education and support to Subjects embarking on the low FODMAP diet, emphasizing the importance of individualized dietary guidance and regular follow-up.

In addition to the low FODMAP diet, current research also evaluated the efficacy of gluten-free and elimination diets in IBS management. While both interventions demonstrated significant improvements in symptom severity, their effects were relatively modest compared to the low FODMAP diet. Gluten-free diet, primarily indicated for Subjects with concomitant gluten sensitivity or celiac disease, may offer symptomatic relief in a subset of IBS Subjects with non-celiac gluten sensitivity [7]. Similarly, elimination diets, which involve the systematic removal of potential trigger foods tracked by gradual reintroduction, have shown promise in identifying and mitigating dietary triggers of IBS symptoms [8]. However, the efficacy of these dietary approaches may vary among individuals, highlighting the need for personalized dietary counseling and careful evaluation of dietary triggers.

The conclusions of this investigation should be interpreted in the perspective of few limitations. Firstly, the heterogeneity among included studies and variability in dietary protocols may have influenced the overall effect estimates and generalizability of findings. Additionally, the reliance on self-reported symptom assessments and subjective outcome measures may introduce bias and affect the accuracy of results. Furthermore, the short-term nature of most included studies limits current ability to measure the longstanding sustainability and durability of dietary interventions in IBS management. Future research should focus on addressing these limitations through well-designed, longstanding prospective studies with standardized outcome measures and objective biomarkers of treatment response.

In conclusion, current research provides significant insights into the efficacy of dietary involvements in managing IBS symptoms and improving QoL. The low FODMAP diet emerges as a promising therapeutic option, offering significant symptom relief and enhancing Subjects' overall well-being. However, the implementation of dietary interventions in clinical practice requires careful consideration of individual patient preferences, nutritional needs, and longstanding sustainability. Healthcare providers should adopt a multidisciplinary approach to IBS management, incorporating dietary counseling, symptom monitoring, and psychosocial support to optimize treatment outcomes and improve Subjects' QoL.
