Abstract:Neuropathic pain (NP) is frequently accompanied by anxiety, and the two conditions often mutually reinforce each other, forming a vicious pain-anxiety cycle that significantly impairs patients' quality of life. In recent years, advances in microbiota-gut-brain axis research have provided increasing evidence that gut microbiota participates in the pathogenesis of both NP and anxiety through neural, immune, and endocrine pathways. Furthermore, intervention strategies targeting gut microbiota modulation have demonstrated promising potential in alleviating pain and anxiety symptoms. However, the specific molecular mechanisms by which gut microbiota contributes to NP accompanied by anxiety remain poorly understood. This review systematically analyzes the potential mechanisms underlying gut microbiota-mediated regulation of NP and associated anxiety, aiming to provide novel insights for the clinical management of this condition.
