I'm 34 and was diagnosed with gastroparesis about 10 years ago through a gastro-emptying study. However, in looking at the symptoms, I don't know that the diagnosis is right. Until recently (like this month), I rarely became nauseated. I've always been a big eater, I'm not malnourished. I have had stomach issues from birth (spitting up consumed food), and maybe I've just always had it so I didn't develop those symptoms in the same way. I don't know. The doc that diagnosed me dismissed me when I refused to be on the medication he prescribed because it made me extremely jittery. A doctor a few years later told me I just "have an intolerance to all food" and dismissed me. I have another stomach emptying coming up and hope I will learn more, but I am wondering how common any of this is.
