IBS-D Causes, Triggers, and Why Stress & Hormones Matter

IBS-D Causes, Triggers, and Why Stress & Hormones Matter

The main IBS-D causes include gut–brain axis hypersensitivity, rapid gut motility, post-infectious changes after gastroenteritis, and gut microbiome imbalances such as SIBO. Triggers like high-FODMAP foods, caffeine, fatty meals, stress, and hormonal shifts can worsen diarrhea, bloating, and urgency. Understanding these causes helps guide diet, stress management, and treatment for lasting relief.
