Effects of Ondansetron on Gastrointestinal Sensorimotor Dysfunctions in Diabetes Mellitus and Dyspepsia
Researchers are trying to understand why people with indigestion and diabetes mellitus have gastrointestinal symptoms and in particular to understand whether symptoms are related to increased sensitivity to nutrients in the small intestine.
