Gluten-Free Diet Shows Promise in Alleviating Fibromyalgia Symptoms

In a groundbreaking revelation, a recent study has unveiled promising results for individuals grappling with the chronic pain and discomfort of fibromyalgia (FM). The study explored the potential benefits of a gluten-free diet (GFD) as a treatment option, and the findings are nothing short of remarkable.

The study results were published in the journal 'reumatisma - The Italian Journal of Rheumatology.'

Fibromyalgia, a baffling and often debilitating condition characterized by widespread musculoskeletal pain, has long eluded medical professionals. The challenge of finding effective treatment options has left countless individuals seeking relief. As per the recent guidelines from the European Alliance of Associations for Rheumatology therapeutic recommendations complementary and alternative therapies like a gluten-free diet (GFD) can improve the symptoms of irritable bowel syndrome (IBS) caused due to the abdominal symptoms of fibromyalgia. A new research team led by Bruzzese V carried out a new study in Italy to treat FM patients with a gluten-free diet (GFD), alternated with a non-restricted gluten-containing diet, followed by a rechallenge of the GFD brings fresh hope to those who have endured the relentless pain associated with FM. 

The study enlisted the participation of twenty postmenopausal women diagnosed with FM. Importantly, none of these participants had a history of celiac disease. The research protocol involved a carefully structured dietary regimen spanning several months. The study began with participants adhering to a GFD for half a year. This was followed by 3 months of a non-restricted gluten-containing diet and then a new GFD for another 6 months. At each visit, the widespread pain index (WPI) and the symptom severity scale (SS) scores were evaluated. 

Findings: 

• After six months on the GFD, significant improvements were observed in two critical measures: the widespread pain index (WPI) and the symptom severity scale (SS) scores.
• WPI decreased from an average of 10.3 to 7.7 which is a statistically significant reduction (p<0.0001).
• Equally noteworthy was the decrease in SS scale scores, which dropped from 6.4 to 4.15 (p=0.0002).
• A marked notable reduction of 24%±9% in WPI and a substantial 36%±21% improvement in SS scale scores after 6 months was seen.
• Following the reintroduction of a gluten-containing diet, there was a statistically significant increase in the absolute SS scale and WPI scores, as well as a change in the percentage modification of WPI (21%±13%) and the SS scale (74%±90%).
• The subsequent rechallenge of the GFD showed significant improvements in both absolute and percentage reductions of WPI (-24%±7%) and SS scale (-36%±11%). Notably, no significant changes were observed in the body mass index of the participants.

Thus, this study provides promising evidence that a GFD can lead to an improvement in FM symptoms, as assessed by WPI and SS scale scores. Moreover, the study introduces a novel element by demonstrating that these improvements were sustained even after a period of consuming a non-restricted gluten-containing diet, followed by a rechallenge of the GFD. These findings open up exciting possibilities for dietary management in FM, potentially offering relief to those who have been living with the challenges of this enigmatic condition. However, further research and larger clinical trials are needed to confirm these results and explore the underlying mechanisms of this dietary approach.
