Fibromyalgia: are you a genetic/environmental disease?

Fibromyalgia, characterized by chronic widespread pain and fatigue, involves complex interactions between genetic predispositions and environmental triggers. This review delves into the multifaceted nature of fibromyalgia, emphasizing recent advances in understanding its pathogenesis through genetic, epigenetic, and environmental lenses. We explore the roles of specific genetic polymorphisms, such as those in the catechol-O-methyltransferase and serotonin transporter genes, and their correlation with the syndrome's susceptibility. The review also examines the significant impact of environmental factors, including physical trauma and stress, which potentiate the syndrome's severity. In addition, emerging research on the microbiome and epigenetic modifications provides new insights into the disease mechanisms, potentially guiding future therapeutic strategies. This article aims to synthesize current research findings and propose directions for future research, underscoring the necessity of a multidisciplinary approach to decipher the complexities of fibromyalgia.
