ask them !

it may be that you are getting a series where they ask you to drink various stuff - I got it in grapefruit juice - to outline the upper bits.


there was a delay in mine and I had to go on being topped up
if there is food there as well, it gets diluted and may not empty at the time wanted.

PP it takes long enough to get through on the phone at the best of times, without hanging on to ask, thats why I am hoping the knowledgeable ab folks may know
I believe it is so they can get clearer images.
sometimes food shows up as opaque lumps on images, also are you having any kind of sedation?
I have no idea and I can see no valid reason for it.

Just do what they tell you.

No not having sedation woofg thank you for link chelle, and rest of the comments
i had an ultrasound two weeks ago, adsomen and pelvic exam, they didn't tell me not to eat, just to drink plenty of water before the abdom exam so i had a full bladder. i'd had lunch maybe 2/3 hours beforehand
The reason for fasting is to ensure there is no food or fluid covering the area that is to be examined, and to reduce bowel gas - ultrasound cannot penetrate this.
Fasting also allows the gall bladder to be seen, as it contracts after eating and may not be seen if the stomach is full.

Sqad, the study referred to in that link appears to have been a very sound one.
Very well done sqad - it will get easier with time:)
Most radiologists unfortunately don't agree...
stewey...I would say..." Ultrasound"....get it?..........Ultrasound.
slaney.....LOL......how did i guess that would be the answer?
Sqad, I was thinking that if I used the term "ultra" in my response it might have made it a little enigmatic.
stewey....indeed!
