Brief Advice

A low fermentable oligosaccharide, disaccharide, monosaccharide, and polyol (FODMAP) diet has been recommended for irritable bowel syndrome (IBS) patients. This study compared the efficacy of two types of dietary advice: (1) brief advice on a commonly recommended diet (BRD), and (2) structural individual low-FODMAP dietary advice (SILFD). Patients with moderate-to-severe IBS were randomized to BRD or SILFD groups. Gastrointestinal symptoms, 7-day food diaries, and post-prandial breath samples were evaluated. The SILFD included (1) identifying high-FODMAP items from the diary, (2) replacing high-FODMAP items with low-FODMAP ones by choosing from the provided menu. The BRD included reducing traditionally recognized foods that cause bloating/abdominal pain and avoidance of large meals. Responders were defined as those experiencing a ≥30% decrease in the average of daily worst abdominal pain/discomfort after 4 weeks. Sixty-two patients (47 F, age 51 ± 14 years), BRD (n = 32) or SILFD (n = 30), completed the studies. Eighteen (60%) patients in SILFD vs. 9 (28%) in the BRD group fulfilled responder criteria (p = 0.001). Global IBS symptom severity significantly improved and the number of high-FODMAP items consumed was significantly decreased after SILFD compared to BRD. Post-prandial hydrogen (H2) breath production after SILFD was significantly lower than was seen after BRD (p < 0.001). SILFD was more effective than BRD. This advice method significantly reduced FODMAP intake, improved IBS symptoms, and lowered intestinal H2 production.

The Impact

ObjectiveA diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) is recommended for irritable bowel syndrome (IBS), if general lifestyle and dietary advice fails. However, although the impact of a low FODMAP diet on individual IBS symptoms has been examined in some randomised controlled trials (RCTs), there has been no recent systematic assessment, and individual trials have studied numerous alternative or control interventions, meaning the best comparator is unclear. We performed a network meta-analysis addressing these uncertainties.DesignWe searched the medical literature through to 2 April 2021 to identify RCTs of a low FODMAP diet in IBS. Efficacy was judged using dichotomous assessment of improvement in global IBS symptoms or improvement in individual IBS symptoms, including abdominal pain, abdominal bloating or distension, and bowel habit. Data were pooled using a random effects model, with efficacy reported as pooled relative risks (RRs) with 95% CIs, and interventions ranked according to their P-score.ResultsWe identified 13 eligible RCTs (944 patients). Based on failure to achieve an improvement in global IBS symptoms, a low FODMAP diet ranked first vs habitual diet (RR of symptoms not improving=0.67; 95% CI 0.48 to 0.91, P-score=0.99), and was superior to all other interventions. Low FODMAP diet ranked first for abdominal pain severity, abdominal bloating or distension severity and bowel habit, although for the latter it was not superior to any other intervention. A low FODMAP diet was superior to British Dietetic Association (BDA)/National Institute for Health and Care Excellence (NICE) dietary advice for abdominal bloating or distension (RR=0.72; 95% CI 0.55 to 0.94). BDA/NICE dietary advice was not superior to any other intervention in any analysis.ConclusionIn a network analysis, low FODMAP diet ranked first for all endpoints studied. However, most trials were based in secondary or tertiary care and did not study effects of FODMAP reintroduction and personalisation on symptoms.

The aim of this study is to evaluate the effect of rice, mung bean, and wheat noodle ingestion on intestinal gas production and postprandial gastrointestinal (GI) symptoms in non-constipation irritable bowel syndrome (IBS) patients. Methods: Twenty patients (13 F, 46 ± 11 y) underwent 8 h breath test studies and GI symptom evaluations after standard rice, wheat, or mung bean noodle meals at 8:00 a.m. in a randomized crossover study with a 1-week washout period. The same meal was ingested at 12:00 p.m. Results: The H2 and CH4 concentration in the breath samples were similar at baseline (rice:wheat:mung bean, H2 = 3.6 ± 0.5:4.1 ± 0.5:4.0 ± 0.7 ppm, CH4 = 1.3 ± 0.3:2.1 ± 0.4:1.9 ± 0.4 ppm, p > 0.05). Beginning at the fifth hour after breakfast, H2 and CH4 concentrations significantly increased after wheat compared to rice and mung bean (8 h AUC H2 = 4120 ± 2622:2267 ± 1780:2356 ± 1722, AUC CH4 = 1617 ± 1127:946 ± 664:943 ± 584 ppm-min, respectively) (p < 0.05). Bloating and satiety scores significantly increased after wheat compared to rice (p < 0.05), and increased but did not reach statistical significance compared to mung bean (p > 0.05). A higher bloating score after wheat compared to rice and mung bean was observed clearly after lunch but not after breakfast. Conclusion: Wheat ingestion produced more intestinal gas and more bloating and satiety scores compared to rice and mung bean, especially after lunch. This provides insight into the role of intestinal gas in the development of bloating symptoms in IBS.

Irritable Bowel

In children, functional gastrointestinal disorders (FGIDs) are common at all ages. Consumption of certain foods, particularly gluten, is frequently associated with the development and persistence of FGIDs and functional abdominal pain disorders (FAPDs) in adults and children. However, this association is not well defined. Even without a diagnosis of celiac disease (CD), some people avoid gluten or wheat in their diet since it has been shown to trigger mostly gastrointestinal symptoms in certain individuals, especially in children. The incidence of conditions such as non-celiac gluten sensitivity (NCGS) is increasing, particularly in children. On the other hand, CD is a chronic, autoimmune small intestinal enteropathy with symptoms that can sometimes be mimicked by FAPD. It is still unclear if pediatric patients with irritable bowel syndrome (IBS) are more likely to have CD. Abdominal, pain-associated FGID in children with CD does not seem to improve on a gluten-free diet. The threshold for gluten tolerance in patients with NCGS is unknown and varies among subjects. Thus, it is challenging to clearly distinguish between gluten exclusion and improvement of symptoms related solely to functional disorders.

The Impact

Malabsorption of fermentable oligo-, di-, mono-saccharides and polyols (FODMAPs) in response to prolonged exercise may increase incidence of upper and lower gastrointestinal symptoms (GIS), which are known to impair exercise performance. This case study aimed to explore the impact of a low-FODMAP diet on exercise-associated GIS in a female ultraendurance runner diagnosed with irritable bowel syndrome, competing in a 6-day 186.7-km mountainous multistage ultramarathon (MSUM). Irritable bowel syndrome symptom severity score at diagnosis was 410 and following a low-FODMAP diet (3.9 g FODMAPs/day) it reduced to 70. The diet was applied 6 days before (i.e., lead-in diet), and maintained during (5.1 g FODMAPs/day) the MSUM. Nutrition intake was analyzed through dietary analysis software. A validated 100-mm visual analog scale quantified GIS incidence and severity. GIS were modest during the MSUM (overall mean ± SD: bloating 27 ± 5 mm and flatulence 23 ± 8 mm), except severe nausea (67 ± 14 mm) experienced throughout. Total daily energy (11.7 ± 1.6 MJ/day) intake did not meet estimated energy requirements (range: 13.9–17.9 MJ/day). Total daily protein [1.4 ± 0.3 g·kg body weight (BW)−1·day−1], carbohydrate (9.1 ± 1.3 g·kg BW−1·day−1), fat (1.1 ± 0.2 g·kg BW−1·day−1), and water (78.7 ± 6.4 ml·kg BW−1·day−1) intakes satisfied current consensus guidelines, except for carbohydrates. Carbohydrate intake during running failed to meet recommendations (43 ± 9 g/hr). The runner successfully implemented a low-FODMAP diet and completed the MSUM with minimal GIS. However, suboptimal energy and carbohydrate intake occurred, potentially exacerbated by nausea associated with running at altitude.

Irritable Bowel

Irritable bowel syndrome (IBS) is a complex, functional gastrointestinal condition characterized by abdominal pain and alteration in bowel habits without an organic cause. One of the subcategories of this disorder is IBS with diarrhea (IBS-D). Clinically, patients who present with more than 3 months of abdominal pain or discomfort associated with an increase in stool frequency and/or loose stool form are defined as having IBS-D. This review addresses IBS-D, detailing the epidemiology, etiology and genetics, pathophysiology and pathogenesis, diagnosis, clinical manifestations and physical examination findings, differential diagnosis, treatment, emerging therapies, complications, and prognosis. Figures show potential mechanisms and pathophysiology of IBS, IBS-D suspected by clinical assessment and Rome III criteria, pharmacologic and nonpharmacologic treatment options, potential mechanisms of action of probiotics, and potential treatment modalities. Tables list the Rome criteria for IBS, alarm signs and symptoms suggestive of alternative diagnoses, IBS criteria, differential diagnosis of IBS-D, dietary advice options for IBS-D, and alternative and emerging therapies in IBS-D.

The Impact

Introduction: Irritable bowel syndrome represents one of the most difficult gastroenterological diseases to treat, that usually induces the patients to follow different drug therapies, often not useful in symptom control. In this scenario low FODMAP diet could have positive effects in patients with irritable bowel syndrome, even because this type of diet regimen is characterized by a low gluten amount due to the exclusion of cereals. Methods: We enrolled 120 patients with irritable bowel syndrome, according to the Rome IV criteria, who were referred to Hepatogastroenterology Division of the University of Campania L. Vanvitelli from June to December 2018. They underwent a low FODMAP diet for six weeks, followed by a gradual weekly reintroduction of every category of food for three months. The patients had a follow-up evaluation for six months after the end of food reintroduction period. We measured abdominal pain with subjective numerical scale from 0 to 10. We evaluated other gastrointestinal symptoms with a questionnaire about symptoms of lower digestive tract, evaluating their frequency and intensity. We also evaluated the impact of irritable bowel syndrome on daily life with neurological bowel dysfunction score. Results: We obtained a good patient-adherence to diet and a statistically significant decrease of abdominal pain, bloating, flatulence, diarrhea, constipation, and neurological bowel dysfunction score (p < 0.001) at the end of the diet. These results remained constant in the follow-up period. Conclusions: We recommend the use of a low FODMAP diet regimen in patients with irritable bowel syndrome in order to control the symptoms and improve the quality of life.

Irritable bowel syndrome (IBS) is commonly diagnosed when the typical symptoms of irregular bowel habit, abdominal pain and distension, and a feeling of incomplete defaecation are not associated with other gastro-intestinal disease. The management of the patient with IBS has been covered previously1 but if dietary advice, reassurance and simple psychotherapy have proved unhelpful the doctor may be under pressure to prescribe as symptoms are usually recurrent. We now review the evidence to support the use of some antispasmodic drugs.
