Abstract

Abstract: This study was conducted to provide an approach for the diagnosis and prognosis of irritable bowel syndrome , with a particular focus on serotonin . The research was conducted in Najaf Governorate, Iraq, from July 1, 2025, to December 1, 2026 . A total of 90 participants were enrolled, including 60 patients diagnosed with IBS and 30 healthy individuals as controls. The results were stratified into subgroups according to age, body mass index , disease duration , diagnosis status (newly diagnosed or under treatment), familial or non , constipation or diarrhea , physical activity and non-physical activity. The results revealed a significant decrease in serotonin level among patients compared to the control group. The present results revealed significant decrease in serotonin in women patients in compare with control . In ages groups that results showed significant decrease in ages group (20-29) years than other groups , also significant decrease in diarrhea group in compare to constipation . The results also indicated a significant decrease in new diagnosed patients than treated ,also body mass index revealed a significant decrease in obese patients than overweight . Shorter duration of disease less than (1 year) showed significant decrease than long more than 1 year . both physical activity and familial status showed a significant decrease than non physical activity and non familial , In conclusion, the study suggests that serotonin is a novel biomarker for irritable bowel syndrome It may serve as a valuable diagnostic and prognostic tool.
