Hi. Thanks of your query. Noted the history and understood your concerns. Gastroparesis does not just happen, there has to be a reason like diabetes or any other medical problem that can cause this. Gastroparesis can be diagnosed certainly only with Barium meal and follow-through examination under fluoroscopy control to directly visualize what the progress is - delayed or fast. Prilosec and Reglan may helps hence continue on. Increase the dietary fibers, whole fruits like banana and those which have high fiber contents. Increase Ghee in food as helps in bowel evaluation. Plenty of oral fluids. Green leafy vegetables. Ans whatever you know give you smooth bowel movements like Ladies fingers also called as Bhindi. These all natural measures will help you the most.
