Effect of Different Dietary Therapies on Intestinal Barrier Integrity in Patients With Irritable Bowel Syndrome

This study aims to evaluate the effects of different dietary treatments on intestinal integrity in female subjects aged 19-50 years previously diagnosed with constipation-predominant irritable bowel syndrome (IBS). At the Gülhane Training and Research Hospital's gastroenterology clinic in Ankara, Turkey, a randomized controlled experiment was carried out. 60 individuals with IBS were randomly divided into three groups. Group 1 was assigned to a regular constipation diet, group 2 to a constipation diet rich in soluble fibers, and group 3 to a constipation diet with probiotic yogurt supplementation. Every individual was monitored for eight weeks. Plasma zonulin level was used to measure intestinal integrity both before and after treatment.
