Surveying the International Prevalence and Nature of Eating, Drinking and Swallowing Difficulties in Adults Presenting with Fibromyalgia

Abstract

Fibromyalgia is a centralized pain syndrome characterized by widespread pain, fatigue, sleep and sensory issues. Fibromyalgia is present in up to 8% of the global population, disproportionally affecting females. Research acknowledges that patients with similar rheumatic/neurological disorders experience eating, drinking and swallowing difficulties. There are also anecdotal reports regarding dysphagia among the fibromyalgia community. However, there is limited research exploring these issues, with potential impact on care delivery and patient outcomes. This study investigated the nature and prevalence of dysphagia in an international sample of adults with fibromyalgia. An online cross-sectional survey design was used to gather data. Questions were adapted from a criterion-based assessment and available evidence. The survey focused on demographics, dysphagia symptoms, and symptom experiences. Results were analyzed using descriptives and correlational analysis. 1983 individuals participated (age range: 18-94), located: Australia (n = 18), Ireland (n = 63), Canada (n = 174), New Zealand (n = 253), the UK (n = 434) and the USA (n = 1024). Many eating, drinking and swallowing symptoms were reported, including food sticking in the throat during swallowing (89%), and pills taking extra effort to swallow (88%), and dry mouth (85%). This study identified previously under-explored eating, drinking and swallowing difficulties among adults with fibromyalgia. These difficulties were self-reported across age, gender, and location, highlighting the potential prevalence of these concerns among a wide range of people, despite having not been explored in depth in previous studies. Timely and accurate dysphagia identification is vital given the its' potential impact on nutrition, prognosis and quality of life. This study highlighted the importance of honoring patient experiences in fibromyalgia management while also recommending input from allied health professionals such as SLTs and dietitians to improve therapeutic relationships and clinical outcomes. As such, continued research into the cause, implications, and management of these issues beyond is required to inform and optimise future patient-centred service delivery and care provision.
