Irritable bowel syndrome (IBS) remains a challenging condition both for patients and clinicians, characterized by its chronic nature and the elusive complexity of its underlying mechanisms. The multifaceted relationship between the neuroendocrine axis, gut microbiota, and inflammatory response has emerged as a focal point in recent research, offering new insights into the pathophysiology of IBS. The neuroendocrine axis plays a crucial role in maintaining the delicate balance between the brain and the gut, often referred to as the "gut-brain axis". This bidirectional communication is essential for regulating gastrointestinal function, stress responses, and overall homeostasis. Dysregulation of this axis, as highlighted by elevated cortisol and serotonin levels in IBS patients, suggests that neuroendocrine imbalances may significantly contribute to the severity of gastrointestinal symptoms. These findings underscore the need for a broader understanding of how stress and emotional factors influence IBS, potentially guiding more effective, personalized treatment approaches. Equally important is the role of the gut microbiota, a diverse and dynamic ecosystem that directly impacts gut health. This dysbiosis disrupts gut function and appears to exacerbate the neuroendocrine and inflammatory responses. These findings align with the growing recognition that gut microbiota is a critical player in IBS, influencing both the disease's onset and progression.
肠易激综合征(IBS)仍然是患者和临床医生面临的一个具有挑战性的问题,其特征为慢性和潜在机制的难以捉摸的复杂性。神经内分泌轴、肠道微生物群和炎症反应之间的多方面关系已成为最近研究的焦点,为 IBS 的病理生理学提供了新的见解。神经内分泌轴在维持大脑和肠道之间微妙的平衡中起着至关重要的作用,通常被称为“肠道-大脑轴”。这种双向通讯对于调节胃肠道功能、应激反应和整体内稳态至关重要。IBS 患者中皮质醇和血清素水平升高表明该轴的失调,这表明神经内分泌失衡可能会显著影响胃肠道症状的严重程度。这些发现强调了需要更广泛地了解压力和情绪因素如何影响 IBS,这可能会指导更有效的个性化治疗方法。同样重要的是肠道微生物群的作用,它是一个多样化和动态的生态系统,直接影响肠道健康。这种生态失调会破坏肠道功能,并似乎会加剧神经内分泌和炎症反应。这些发现与越来越多的认识一致,即肠道微生物群是 IBS 的关键参与者,影响疾病的发生和发展。
