Study Finds Dietary Changes More Effective Than Medication for Managing IBS Symptoms

A recent study conducted at the University of Gothenburg suggests that dietary adjustments may offer more effective relief for irritable bowel syndrome (IBS) than traditional medications. The study, published in The Lancet Gastroenterology & Hepatology, revealed that more than seven out of ten patients experienced significantly reduced symptoms with dietary modifications.

The study involved adult patients with severe or moderate IBS symptoms and compared three treatment methods: traditional dietary advice focusing on eating behavior and low intake of fermentable carbohydrates (FODMAPs), a dietary plan low in carbohydrates and high in protein and fat, and medication tailored to individual symptoms. Results showed that the groups receiving dietary interventions experienced greater symptom relief compared to those on medication, with 76% of patients following traditional IBS dietary advice and low FODMAP intake reporting significantly reduced symptoms, and 71% of those on a low-carbohydrate, high-protein, and fat diet experiencing relief. In contrast, only 58% of patients in the medication group reported reduced symptoms.

Why this matters: IBS is a common condition that affects an estimated 6% of people in the US, with more women diagnosed than men. The study highlights the importance of personalized treatment for IBS and suggests that dietary changes may be more effective than medication for managing symptoms.

All groups in the study reported better quality of life, fewer physical symptoms, and less anxiety and depression. The researchers also found that a large proportion of participants in the dietary groups still had clinically significant symptom relief at a six-month follow-up. "The study emphasizes the importance of personalized treatment approaches for IBS and calls for further research to identify factors predicting individual responses to different treatment options," said the lead researcher.

The study concludes that diet plays a central role in the treatment of IBS and that further investigation is needed to personalize IBS treatment options. The researchers plan to investigate factors that can predict individual responses to different treatment approaches. While the low-carbohydrate, high-protein, and fat diet was effective, it was associated with a small rise in blood cholesterol levels, so participants were advised to seek their doctor's advice before adopting this diet.

Key Takeaways

• 76% of patients on traditional IBS diet saw reduced symptoms
• 71% of patients on low-carb, high-protein diet saw symptom relief
• IBS affects 6% of US population, more common in women
• Low-carb diet effective but may raise cholesterol, requires doctor's advice
