What helped me was botox to the lower stomach muscle. An injection was given in 3 places via endoscopy so food always goes into the small intestine. With gastroparesis, the stomach nerves can be so damaged that the contraction (peristalsis), is so slow that by the time the food reaches the lower stomach to enter the small intestine, the pyloric sphincter (muscle opening) closes, keeping the food in the stomach. That is what causes all the nausea, fullness, bloating and vomiting. It also can become the source of infection. Very serious. A special diet is needed of easily digested foods like white bread no wheat, oat, seeded breads, i.e.. I use gummy or chewable vitamins and liquid medicines also. March 2014 I had the procedure at Hershey Medical Center in PA and it is still working. Mine was severe. I would NOT get a pacemaker! There is no guarantee on how long this lasts but so far so good. I use liquid erythromycin as a prokinetic (muscle contractor) for the stomach. The procedure took only 15-20 minutes and no pain. Rare nausea and not that constant loss and gaining of weight, unable to tolerate smells and look at food…etc. A real blessing.
