Summary

This study is creating a long-term group of 600 people with irritable bowel syndrome (IBS) to track how the disease changes over time. Participants will fill out questionnaires about their symptoms, quality of life, and habits, and provide stool samples every six months. The goal is to better understand what factors influence IBS and its outlook.
