Depends on the extent of the gastroparesis. You could have a somewhat manageable case, but you know what? You don't know what tomorrow can bring. For those with a severe case, once their bodies reject tube feeding and their body weight plummets, the body begins to consume itself and major organs shut down. For some they could live 30 years.... who knows and some succumb in 5 years. This question hasn't no definitive answer- impossible to answer
