| My GI doctor said the same thing about type 1s and Celiac. I'm in the lucky 80% though.
Endoscopies are easy, but most people have the blood test first and only get the scope if the blood test is positive. I had the scope cause I needed one anyway.
I've had 2 endoscopies. The first was under general anesthetic when I was 16. That was really easy.
The 2nd was under "twilight" (demerol and verced) when I was 20. That one was easy too for the actual procedure. I don't remember any of it and slept through it. However, when I started waking up I was having nasty hullicinations and couldn't stop crying and vomiting. Gah. They drugged me up more, I slept for a loooonnnnggg time and life was good. |
