Gastroparesis

I have been diagnosed with gastroparesis, and when I asked my MS specialist about it being an MS symptom, he told me it was not. However, when I asked my gastroenterologist, he told me it is a symptom of MS. Also, from what I've read on the internet, it seems it can definitely be a MS symptom. Has anyone else been diagnosed with this, and have you had success in managing it? Do your doctors consider it an MS symptom?
