Do you fast for a GTT

[sunnyawry]

I have a GTT booked for next week and can't find the leaflet. Does anyone know if this is a fasting test?

Mine was. You could just ring and ask them, everywhere seems to have slightly different procedures.

I had to fast overnight (10 hours) before min.

I had to fast from 10pm. Only water the following morning and no water once I'd had the syrupy drink.

Thank you, I have found the letter and it doesn't mention anything so will ring them as suggested.

I had a glucose challenge test initially and no starving involved. I just turned up at a time convenient to me drank the lucozade and then had blood taken an hour later. Got a different glucose test tomorrow (moved areas) that also doesn't involve fasting but I have a breakfast menu of 75g carbohydrates with a blood test two hours later. Worth checking to see what your test involves.

I have mine Monday, my letter says no food from 10pm except for plain water. It says to eat as you normally would for 3 days before.

Not looking forward to it!

I have to fast for 12 hours except water. Am dreading it as so hungry at the moment!!

Mine was 12 hours.

So 8:30pm to 8:30am when my test was I was only allowed water till 7:30am. I'd then have my bloods. Drink a carton of sickly syrupy glucose drink (not lucazade where I am) and then wait 2.5 hours where you're not allowed to drink anything for another blood test.

The drink isn't pleasant it's 'orange' flavour apparently but if you're sick during the test it invalidates it and you'll have to do it again

Mine was 12 hours too. Test was at 9am so no food or drinks except water from 9pm the night before. They take blood then give you horrible sweet drink, you wait 2 ish hours then give more blood. It's a PITA. Take some food with you so that as soon as you have the second bloods taken you can eat something, I felt quite faint by 11.30 when they finally got some blood out of me and was worried about walking home without food, certainly don't drive without any. I also took a bottle of water that I'd frozen to keep me cool as waiting rooms are always so hot and stuffy.

Yup, I have mine on 18th May. Have been instructed to fast from 8pm until the appointment at 9.15am, then 2 hours as described above.

I'm more concerned about being bored out of my wits than the actual test; we have a family history of diabetes on both sides so just happy that I'm being tested to enable me to manage it if needs be for the rest of my pregnancy, and make sure that I don't give birth to a humungobaby!

Mine is at 9:30am, I am going to be so hungry!!

I was measured as 3 weeks ahead yesterday so I guess I had better get on with it.

Mine was a fasted test, I vaguely remember something about tap water being ok but not bottled water? Definitely worth ringing to check :)

I'm in the US so things seem a bit different here, but I just did a glucose screening, no fasting, just drink the sweet drink and then they test your blood in an hour.

I passed that so I didn't need the proper test, which definitely involves fasting. Over here they screen everyone, and then I assume you do the more involved test based on your results.
