okay to exercise before blood test?

[redrhodie]

I have to have some blood work done, a liver function test (because of the tamoxifen) and a thyroid test. Both are non fasting. The lab is on the way to work. Will riding there throw anything off?

[lph]

Not sure it makes any difference, but I remember riding quite hard to one blood test which was supposed to be non-fasting, and then measuring blood glucose which was down at a fasting level. Just burned it all right off I guess.

You should be fine to ride before those two tests. It's not a 100 miles to work, is it? You'll be fine.

I'm actually wondering the same thing. I know not to get blood tests done right after a marathon, but what about a really tough half?

[malkin]

Don't know anything about the science, but sending good wishes for passing your blood tests with flying (riding?) colors.

[lph]

My unscientific guess is ride but ride easy. If it was important not to exercise right before they would have told you so.

Yay! I'm hypothyroid! I was hoping! I got an rx for Synthroid.

When I told my oncologist my hair has been thin and brittle, she thought it might be my thyroid. I've been really tired and low energy for a long time, too. I'm so relieved there's a reason other than tamoxifen side effects. Hoping this makes me feel better.

No results yet on the liver function test.

And I did ride there.

Welcome to the Synthroid club. I've been on it for about a month. I've yet to have new labs done to see if it's helping. I feel better, but my hair is still uncooperative.

[redrhodie]

The hair issue is the pits, so I hope yours responds, Indy. Mine still could be the tamoxifen, but I have hope.

[indysteel]

I hav stubborn hair anyway, so the fact that it's grown limp and lifeless is par for the course. At least I don't feel like crying all the time anymore!

I hope you feel better soon, Red. There are some past threads about how and when to dose. I take mine in the middle of the night. I have to get up to pee anyway, so I kill two birds. Be sure to take it with a full glass of water.

This doesn't mention exercise, but interesting info about timing of and fasting for thyroid blood tests:

Took me until today to get up the guts to go in - I have meltdowns around needles. Guess I'll hear if it's iron, thyroid, or other soon enough.

Interesting. I almost always get my blood drawn in the morning and since I'm not a breakfast eater on work days (I know, but I have zero appetite until 9 or 10). I'm not on a T3 drug, so I don't think I'll skip the day's meds either.

@Jess. Sorry you're not feeling well. Let us know what the tests reveal.

[jessmarimba]

Thanks. I'm probably overreacting to what is likely job-related burnout but I've been totally wiped for months. My mom has thyroid problems so we figured it was time to check everything out. If nothing else, I now will have baseline comparison numbers for the future.

I took my first pill three nights ago (like Indy, the middle of the night works best for me) and I swear I felt better that day. I was walking to the store, and it dawned on me that a weight had been lifted. I know this is impossible, but I think my hair seems a little better. It feels soft. That could just be wishful thinking, but my boyfriend even thought so.

I wonder how long I've had this. I never had the weight gain that usually is the main symptom, but I've always been cold and tired. At least since high school. Maybe it was a little low all along, then the BC treatments affected it? But so far, so good. I felt really strong on my commute yesterday, too.

Good luck, Jess. The test didn't hurt at all. I hope you get clear answers.
