Is this trial a fit for you?

Likely a good fit

Adults 30–65 with confirmed fibromyalgia (ACR criteria) and Rome III/IV IBS with an IBS-SSS score ≥125, BMI 18.5–29.9, and no severe cardiac, hepatic, neurological, or psychiatric disorders.

Probably not a fit

People with severe comorbid illnesses, BMI outside 18.5–29.9, those unable to discontinue symptom-management medications, or those with only mild IBS are unlikely to be eligible or benefit.

What this trial studies

This randomized crossover trial recruits adults with both fibromyalgia and irritable bowel syndrome from outpatient clinics at IRCCS Saverio de Bellis in Italy. Participants will follow periods of a structured exercise program (including aerobic exercise) combined with an IBS-specific nutritional plan, with each participant receiving different interventions in separate phases. Outcome measures include symptom diaries, accelerometer monitoring of activity and sleep, blood/urine/stool sampling, and validated questionnaires on GI symptoms, fibromyalgia, psychological status, and quality of life. The crossover design lets each person serve as their own control to compare changes in pain, GI symptoms, sleep, and metabolic markers.

Why it matters

Potential benefit: If successful, the program could reduce pain, improve sleep and physical function, and lessen IBS symptoms, improving daily quality of life.

How similar studies have gone: Previous research shows exercise can help fibromyalgia and dietary strategies can reduce IBS symptoms, but combining a structured exercise program with an IBS-specific diet in a randomized crossover format is relatively novel.
