Abstract：
BACKGROUND: Diet plays an important role in management of gastrointestinal (GI) symptoms in patients with irritable bowel syndrome (IBS). Restrictive diets have gained popularity as treatment for IBS, but no studies have examined the patients\' experiences of implementing such diets. Thus, the present study aimed to explore the experience of patients with IBS undergoing a structured dietary intervention.
METHODS: Using inductive content analysis, semi-structured interviews were conducted in 19 patients with IBS, who were recruited from a randomised controlled trial evaluating two different restrictive diets for 4 weeks: a diet low in total carbohydrates; and a diet low in fermentable oligo-, di- and monosaccharides and polyols (i.e., FODMAP) combined with traditional IBS dietary advice.
RESULTS: Three main themes developed from the qualitative analysis and together they describe the dietary intervention as supportive, as well as the dietary changes as challenging and contributing to reflection. Patients found the dietary support effective in both initiating and adhering to their dietary changes. Despite the support, the implementation of the diet was perceived as challenging when it interfered with other important aspects of their lives. However, going through the dietary change process, the patients began to reflect on their eating behaviours, which enabled individual dietary adjustments. The adjustments that patients maintained were not only a result of alleviation of GI symptoms, but also based on personal preferences.
CONCLUSIONS: Patients with IBS undergoing restrictive diets appear to benefit from structured support. However, considering the individual patient\'s life situation and personal preferences, individualised dietary options should be encouraged to achieve long-term dietary changes.

摘要：
背景：饮食在治疗肠易激综合征（IBS）患者的胃肠道（GI）症状中起着重要作用。限制性饮食作为IBS的治疗方法越来越受欢迎，但没有研究检查患者实施这种饮食的经验。因此，本研究旨在探讨IBS患者接受结构化饮食干预的经验.
方法：使用归纳内容分析，对19例IBS患者进行了半结构化访谈，他们是从一项随机对照试验中招募的，该试验评估了两种不同的限制性饮食，为期4周：总碳水化合物含量低的饮食；和可发酵寡头饮食含量低的饮食，二糖和单糖和多元醇(即，FODMAP）结合传统的IBS饮食建议。
结果：从定性分析中得出的三个主要主题，它们共同将饮食干预描述为支持性的，以及饮食变化具有挑战性并有助于反思。患者发现饮食支持在启动和坚持饮食变化方面均有效。尽管有支持,当饮食干预他们生活的其他重要方面时，饮食的实施被认为是具有挑战性的。然而,经历饮食变化过程，病人开始反思他们的饮食行为，这使得个体的饮食调整。患者维持的调整不仅是胃肠道症状缓解的结果，但也基于个人喜好。
结论：接受限制性饮食的IBS患者似乎受益于结构化支持。然而,考虑到患者个人的生活情况和个人喜好，应鼓励个性化饮食选择，以实现长期饮食变化。
