I just had my gastric emptying test yesterday. I was given oatmeal with the stuff they put in it to be able to take the pictures of my stomach. I have been really sick since. I have had diarreah and sick to my stomach all day. I usually am constipated, that's why I'm wondering if this stuff they put in the oatmeal could have actually made me feel worse than I already am. Has anyone else had this experience after having their GES test done? The tech that did my test seems to think I passed and I don't have GP---although I sure do feel like I have it. Has anyone passed this test and found out later they did have GP after all? What can I take for the constant upper stomach fullness and nausea even if it's not GP???? Thanks for any info because I'm miserable!!!
