The problem with it is that it can cause a lot of problems, and one of the big ones is dumping syndrome (basically the opposite of
gastroparesis). Also depending on what caused your
gastroparesis, it can actually cause more problems like nausea. For instance, my gastroparesis is caused by an autonomic neuropathy, so even though my stomach is the worst, my entire GI tract doesn't work well, so in my case, a pyloroplasty wouldn't be helpful. What medications have you tried?
