Mreyn, do you mean treatment for gastroparesis? If that is what your son has, first exclude mechanical obstruction, next look at what might be causing the gastroparesis and try to improve it (ie. Better diabetic control - usually won't fix it, but might stop it getting worse). Next, gastroparesis tends to have periods when it is worse than others. During a bad period, I would suggest avoiding solid food and stick with liquid food, much easier to tolerate. Also, there are medications that improve gastric emptying, mild ones like motilium and maxolon, and then stronger ones like erythromycin (only need small doses, ie. 50mg or so), takes these around 30 mins before meals.
