益生菌与肠易激综合征

摘要

人类肠道作为消化和营养吸收器官，在维持整个机体的健康方面发挥了重要作用，这一作用的发挥与肠道菌群是分不开的。肠易激综合征（ IBS）是一个世界性问题，其发病与肠道菌群有关，但确切的作用机制尚不明确。 IBS虽不是致命性疾病，但其严重影响了人们的日常生活，降低了生活质量，同时也给医疗健康和整个社会带来了巨大的经济负担。因此，寻找一种有效的方式来缓解这一现状迫在眉睫。而益生菌治疗IBS的目的即在于重建被破坏的肠道微生态环境。%As a digestive and nutrition uptake organ , human intestine plays an important role in keeping the whole body′s health,which cannot be separated from intestinal flora .Irritable bowel syndrome(IBS) is a global problem.Many lit-eratures have reported the relationship between IBS and intestinal flora though the definite mechanisms of action have not yet been elucidated .Even though IBS is not a life-threatening disease , it indeed severely influences people′s daily life and decreases the quality of life .Meanwhile ,it brings a huge economic burden on the healthcare system and the whole society .So it is imperative to find an effective way to relieve the condition .Probiotics,as a treatment for IBS ,aims at re-establishing the disturbed equilibrium of micro-ecological environment in gastrointestinal tract .
