fasting blood test and your meds

hey everyone  - i all ready did this but just was curious what you do or think ....  I had to go in for my 6 month diabetic check up today - so loads of bloodwork and had to fast - when i made the appt it was last minute so i was not able to get in until 10:30 am - (imagine waiting until after 11 am for your first cup of coffee!  OYE! LOL)  so i will never do that again!  i normally go for 8-8:30 if possible but again it was a last minute appt type thing...  but seeing it was later in the morning which i never do I was not sure if I should have still took my meds or not  - my morning ones - being thyroid meds, and 3 oral diabetic pills - I normally just would have taken them after my usual 8 am fasting appts but seeing this was later and i was away from home i took them w/me and when at the school asked the school nurse what to do - she said to just take them -  what have you done?  I would imagine they would want you to take meds as you normally do so you have more accurate blood test readings - however - i was worried taking my diabetic pills so early w/me not having my first food for the day until basically lunch - was afraid of going too low kwim?    thoughts?

Re: fasting blood test and your meds

Karen, when ever I have an appointment that late in the morning and fasting is required. My doctor has told me to take my medications at the normal time.

Karen,

 

I would not take the metformin nor the Glimepiride without eating first.  Probably not the Actos either.  Metformin will cause stomach upset if you take it on an empty stomach, Glim. could cause you to go low.

 

Next time bring a snack with you to eat as soon as the tests are done.  That's what I do when I have a late test.

well i ended up taking them about 10ish and they drew my blood about 11 - i didn't have any stomach issues but i grabbed a granola bar (They have them by their water cooler! lol) and ate it right away -   the coffee was the hardest!  I took my blood test in the car before i went in (brought my meter) and it was 118 -  when i woke up it was 100 - i think it started going up because of going so long w/o eating?   and the meds didn't kick in yet - for sure next time i will make sure to schedule those appts AT 8:00!!!!!

i ended up taking them an hour later - if i took them at normal time (8 ish am) and they didn't draw my blood til 11 am i was afraid of going TOO low w/the meds - i hope this all worked w/my test!

I think your doctor made that recommendation based on the fact that only just take metformin for diabetes  Metdormin doesn't cause lows, but glimipride does, so I'd have avoided that one.  Metformin doesn't cause me any stomach upset, but it does for a lot of people.  Delaying that one wouldn't have any real consequences, even skipping a day wouldn't be a problem for most of us.

and see as i said i tested before going in the office had my meter on me and it showed 118 and that was after taking the actos and glimeperide and metform an hour prior - though i think since tech at that point i was on a 14 hr fast time i think my body was starting to go into liver dump or something so i didn't have too low a low.....    yeah my stomach issues w/met are long gone have been on this one for 8 years my body is use to it the first 3 months 8 years ago though was another story! lmao

Re: fasting blood test and your meds

When I have bloodwork done, there are some meds that are withheld, others not.  Depends entirely on the type/s of bloodwork you're having done, and what your doctor/s instruct.

 

For my fasting labs, I also have to withhold caffeine, only water is OK, but for some other labs I can drink coffee or tea.

 

Cheers,

xena

I never thought that taking my Metformin before a fasting blood test could cause a liver dump. That is good to know.

well I just am wondering because - its odd that i woke up (pre-meds) and my blood sugar was 100 - then an hour later i take my meds and another hour later its 118 but i didn't eat or drink anything? so i am thinking regardless because it was so long since i ate it was causing my #'s to actually go up (the way they say the liver starts dumping sugar because it thinks you are starving yourself) because you would THINK taking my meds and still not eating yet it would have dropped!  hmmm
