4Celiac disease
Another common cause of diarrhea is celiac disease, a disorder that causes damage and inflammation to your small intestine. It is usually triggered by gluten. However, it might be hard to link it to a specific food or meal because the gut is damaged. The disease often lasts more than 4 weeks with many possible symptoms, such as lack of growth in kids, lack of energy, unexpected weight loss. Your stools might be bad-smelling, large, greasy, and would float in water. With the right treatment, diarrhea could be reduced after a few days. [4]
