Introduction: Irritable Bowel Syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain, bloating, and altered bowel habits. The low FODMAP diet (Fermentable oligosaccharides, disaccharides, monosaccharides and polyols) is one of the most documented dietary interventions in IBS, though its application may be limited by psychological and economic factors.
Objectives: To evaluate the effectiveness of a personalized nutritional intervention based on the low FODMAP diet, considering both patient-centered needs and food waste reduction.
Material and Methods: A 26-year-old female patient with IBS diagnosed according to Rome IV criteria was studied using a case study design. Symptoms were assessed with the Gastrointestinal Symptom Rating Scale (GSRS), dietary-health interviews, and body composition measurements by bioelectrical impedance. The intervention lasted seven months and followed three phases of the low FODMAP protocol, incorporating psychological support and the zero-waste concept.
Results: A significant improvement was observed, with gastrointestinal symptoms reduced and quality of life enhanced. The mean GSRS score decreased from 6.0 to 1.9 points. Although statistical analysis was not applicable due to the single-case design, the observed change (average reduction of 4.1 points) suggests clinical relevance. Discussion: Evidence from meta-analyses and randomized trials supports the low FODMAP diet in reducing IBS symptoms. At the same time, this dietary approach requires individualization and professional supervision, as it may limit dietary diversity and contribute to psychological burden.
Conclusions: Personalized dietary therapy based on low FODMAP principles may be effective in managing IBS, particularly when combined with nutritional education and an eco-friendly approach. The results are consistent with current literature supporting the efficacy of the low FODMAP diet in reducing IBS symptoms. An additional advantage of this intervention was integrating the zero-waste principle, which positively impacted both the patient’s economic situation and nutritional awareness.
