- Patients with irritable bowel syndrome (IBS) experience significant symptom relief with a diet low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP), even after reintroducing high FODMAP foods.
Why this matters
- Growing evidence suggests that the low FODMAP diet is effective in reducing gastrointestinal symptoms in patients with IBS.
- Researchers studied the health records of patients with IBS consuming personalized diets developed by a FODMAP-trained dietician (N=127; women, 85%; median age, 45 [range, 16-80] years).
- They evaluated IBS symptoms with a questionnaire at baseline and 3-, 6-, and 12-month follow-up appointments.
- Funding: None disclosed.
- The most common baseline symptoms were lethargy (92%), bloating (91%), flatulence (91%), and abdominal pain (89%).
- All symptoms significantly improved by 3 months and remained so at 6 and 12 months (P<.0001 for all>
- All the patients who reintroduced high FODMAP foods maintained symptom control at 6 months (n=14) and 12 months (n=7; others lost to follow-up).
- The study was retrospective with a small sample size.
- Patient symptoms were self-reported.
- More studies are needed to assess the low-FODMAP diet's long-term safety.
