Dysbiosis and Gastrointestinal Dysfunction in Ischemic Stroke: A New Frontier for Treatment

Background: Ischemic stroke (IS) is a leading cause of mortality and disability worldwide. Recent evidence suggests that gastrointestinal (GI) dysfunction and dysbiosis, an imbalance in the gut microbiome, may play a significant role in stroke pathophysiology. This article explores the relationship between gastrointestinal dysfunction, dysbiosis, and ischemic stroke, highlighting the potential for therapeutic interventions to improve patient outcomes.

Methods: A comprehensive review of the literature was conducted to explore the mechanisms linking ischemic stroke to GI dysfunction and dysbiosis. Studies published between 2000 and 2024 were examined for evidence of GI involvement, alterations in the gut microbiota, and potential therapeutic strategies targeting these factors.

Results: GI dysfunction, including impaired gut motility, intestinal permeability, and gut microbial imbalances, has been observed in ischemic stroke patients. Dysbiosis may contribute to stroke-related inflammation, immune responses, and long-term complications. Preclinical and clinical studies suggest that restoring gut microbiota balance through probiotics, dietary interventions, and gut-targeted drugs may offer promising therapeutic avenues.

Conclusion: Gastrointestinal dysfunction and dysbiosis represent important areas of research in ischemic stroke pathophysiology. Targeted interventions aimed at the gut microbiome hold promise for improving outcomes in ischemic stroke patients, though further clinical studies are needed to confirm these findings and optimize treatment strategies.
