World IBS Day, observed worldwide every April 19, aims to combat the stigma surrounding irritable bowel syndrome (IBS) and educate the public about its symptoms, diagnosis, and treatment options. Established in 2019 by the IBS Patient Support Group, which was founded by Jeffrey Roberts, an IBS sufferer, the day highlights the significant impact of this gastrointestinal disorder on quality of life. Common symptoms of IBS include bloating, stomach aches, and changes in bowel movements, with risk factors such as stress and family history. On this day, various stakeholders, including patient organizations and concerned individuals, organize seminars, webinars, and social media campaigns using the hashtag #WorldIBSDay. In some locations, landmarks are illuminated in periwinkle to further promote awareness of IBS.
