Other causes include: * binge eating associated with bulimia nervosa * tumors causing obstruction * diabetic neuropathy * scarring due to pyloric gastritis * delayed gastric emptying To identify the cause of gastric distention, an upper endoscopy or barium Barium is a chemical element with the symbol Ba and atomic number 56.
