I don't have chronic nausea or vomiting. Sometimes I do feel really sick after eating, and wish I could vomit, but I can't.
But I have reflux frequently. My stomach starts bloating as soon as I eat or drink anything, and sometimes it feels "sloshy" for hours after I eat, like everything I ate is still in there. It is really uncomfortable and sometimes it is painful.
What's weird is, you'd think I'd have chronic heartburn, but I don't. It's very rare for me to have heartburn.
I also have night sweats, and I was surprised to see this listed as a symptom. Not sure what the connection is.
I've had trouble with reflux since I was a teenager. When I was around 16 I got checked out to see if I had a hernia, but they didn't find anything.
My dad has the same problems with reflux and bloating, and he has Barrett's disease. The lining of his esophagus has turned black. He said, he told a doctor that he felt like food was still in his stomach for hours after eating it, and the doctor told him that was impossible. I think the doctor was wrong. lol
Anyway whatever is causing it, I think we have the same condition and it must be inherited. Still thinking on there being Parkinson's or some type of parkinsonism in the family.
