Egd stomach scope scheduled for 28th sept. my gi problems n symptoms has worsened. including weight loss of 10 pound in just one week. can i ask for scope to be done sooner. is it legit reason ?

GI: Try and get in before the scheduled 28th. If you can't get in but have those worsened symptoms please have someone take you to the nearest Emergency facility.

Don't wait 5 days: If you really lost 10 pounds in a week I assume you have not been eating or drinking or you have severe vomiting and/or diarrhea. As such you are likely dehydrated and should be feeling ill at this point and I would not wait 5 days to see a physician. See if you can see your GI now, and if not, you should go to the ER for evaluation.
