The low FODMAP diet eliminates carbohydrates and fermentable alcohols because they are not absorbed by the intestine, but are fermented by the micro biota, causing bloating and flatulence [1]. FODMAP includes short chain carbohydrates like fructose and lactose, fructose and galactosaccharides, sorbitol and mannitol [2]. Patients with functional gastrointestinal disorders present with symptoms like excessive intestinal gas manifesting as bloating and flatulence. In recent studies the low FODMAP diet has demonstrated effective in the treatment of irritable bowel syndrome (IBS), however, not exist papers that evaluate this treatment in Mexican patients [3]. The aim of this study is to evaluate de clinical response of a low FODMAP diet in a group of Mexican population with the diagnosis of IBS in any or its variants.

Materials and Methods

We conducted a clinical, prospective, longitudinal, comparative and experimental study. Patients attended at the Gastroenterology Department in 2014 that were diagnosed with IBS base on the Rome III criteria were included. They were managed with a low FODMAP diet for 21 days and their response to the symptoms of abdominal pain, bloating, flatulence and stool form pre and post-diet were evaluated through the visual analogue scale, Bristol scale and patient overall satisfaction.

Patients were included in an initial visit, in which the patient usual diet was register. They were cited once a week during the two weeks prior to the start of dietary treatment to evaluate the basal visual analog scale (VAS) and Bristol scale (BS). In the second visit it gave them a diet in writing with the forbidden foods. The patient has to register his daily meals.

The clinical response was evaluated once a week during the three weeks of treatment. The results were analyzed by means, 95% CI and the t Student’s test.


Of the 31 patients included in the study, 87% were women and the mean age was 46.48 years. Distribution eas: IBS-C 64.5%, IBS-D 22.6% and IBS-M 12.9%. The score for pain was 6.0 (95% CI 5.04-6.96) and the post-diet score was 2.77 (95% CI 1.60-3.95) (p<0.001). The score for bloating was 7.10 (95% CI 6.13-8.06) and the post-diet score was 4.19 (95% CI 2.95-5.44) (p<001). The score for flatulence eas 5.94 (95% CI 4.79-7.08) and the post-diet score was 3.06 (95% CI 1.99-4.14) (p<0.001). The pre-diet Bristol Scale result was 3.68 (95% CI 3.14-4.22) and the post-diet result was 4.10 (95% CI 3.66-4.54) (p=0.1). The satisfaction percentage was 70.9%.


The present study evaluated the clinical response in Mexican patients of the common symptoms in IBS (abdominal pain, bloating, flatulence and stool form) treated with low FODMAP diet. Although IBS is one of the most frequent causes of consultation (with a mundial incidence between 10 and 20% and an incidence in Mexico in different studies between 16 and 35%) [4,5]. An important number of patients refers that some foods cause their symptoms. In the recent years it has focused attention on various diet modifications. Low FODMAP diet was shown efficacy in multiple studies [6]. The strengths of our study are that were included patients of different areas of our country so the population is more representative, but is important to extend the sample to other areas of Mexico to confirm our results. This is the first study of treatment of IBS in Mexico with low FODMAP diet proving that this approach will be useful to our patients with IBS in all its variants.

    This study evaluates the beneficial effects of low carbohydrate diet in Mexican patients with Irritable Bowel Syndrome. Diet which is rich in carbohydrates like fructose and lactose and similar foods were eliminated from the diet for the study period. Past studies showed beneficial effects of low carbohydrate diet, however in this study the authors systematically evaluated this dietary intervention in Mexican patients.
