“Bad news?” or “Does running affect GH?”

November 26, 2008 at 9:51 am 6 comments

sad_cartoonThis morning I went to pick up my last bloodwork results and I was shocked to see this:

IGF-1 309 ng/ml (114 – 492)

GH 12.50 µg/l (0 – 6.88)

What is this supposed to mean???

This is a blood test done at the beginning of september. One week later I talked to my endo on the phone and she informed me of the results. She only said, IGF-1 is 309, that’s good. Everything is all right. Call the secretary for an appointment in 3 months for a glucose tolerance test.  I asked if I could have the results printed and she said, whenever you come along, ask for a copy. So I thought everything was all right and I was happy. I called for an appointment for a GTT and that’s scheduled for monday the 1st. I was close to the doctors today and I walked in to ask for a copy of that bloodwork… and then I found that GH is way higher than what it is supposed to be.


This, automatically brought me back to the beginning of my condition. For a loong, loooong time, my GH was way too high and my IGF-1 was in the normal range. Every doctor I saw told me not to worry, if IGF-1 is in the normal range, I am not ill. They explained the IGF-1 is a measurement of the GH of the last 24 hours and that GH could be anormally high in some moments of the day. But then, one day, IGF-1 was not in the normal range anymore. They said I had a GH (and PRL) producing tumor (the chickpea) and you know the rest of the story. Noone was able to explain why I had GH anormally high throughout the years with a normal IGF-1 and suddendly, the IGF-1 was not normal anymore.

So, obviously I am concerned. Is this the beginning of the nightmare again? Will it be like this (GH high, IGF-1 normal) for a few years and then, unexpectedly, IGF-1 will rise again and will I be back to the neurosurgeon? The only thing that keeps this little magpie from getting depressed is very simple: I ran to the doctors the day of the test. And when I say “ran” I mean sprint really, really, really fast. Well, I was late… I asked the nurse while she was doing the test and I was still trying to catch my breath if the running would anyhow affect the hormone values, and she said no. I guess she didn’t know what she was taking the blood for, because I’ve read everywhere that sport rises the levels of GH.

The question is, could a sprint be responsible for such a high value of GH?

Next GTT: monday the 1st.

Next Endo appointment: monday the 8th.

    Don’t be discouraged. From what I understand it’s the IGF-1 value that is important, not GH itself.

    Yes, exercise does cause a “spurt” of Growth Hormone. That could very well explain it. Get a taxi next time!

    Don’t worry yourself (stress increases GH too!) – remember it’s the IGF-1 that matters and you’re doing great.

    Sorry, I forgot to add – some medical treatment for acromegaly only controls the production or the effect of IGF-1 and ignores the GH altogether. The reason is that GH in itself does no real harm, but the IGF-1 does. It’s only IGF-1 that has the real effect. You’re fine. (Check with your Endo!)

    Hi Trys!

    Thanks for trying to cheer me up! I know, I know, IGF-1 is the only important hormone and GH rises with sport… … but still, if I had the choice, I’d rather have GH low as well!!!

    I try to convince myself it’s because of the run… and I’m pretty good at it (at convincing myself, not at running)… but until I visit the endo on monday and I check the results of my last OGTT I won’t be 100% convinced that the nightmare is over… Next piece of news on tuesday! Keep your fingers crossed!

    “Is this the beginning of the nightmare again? Will it be like this (GH high, IGF-1 normal) for a few years and then, unexpectedly, IGF-1 will rise again and will I be back to the neurosurgeon?”

    You know, ultimately it’s always hard to know for sure. Just stay on top of it and wait for the OGTT. That’s the tell-all test from what I understand. GH does go in spurts so they could’ve drawn when you were having a spike. That happened to me – my GH was 8ng and I panicked because before surgery I hadn’t seen it above 4.85. I was asking myself the same questions.

    I hope you get the good news you hope for…standing by for the updates.

    Thank you Alecia! I’ll be on tenterhooks until monday the 8th (still 4 days…)… deep inside me I am pretty convinced it was a spurt, but … until I don’t hear it from the endo I won’t feel relieved. You’ll get an update soon. Keep your fingers crossed!
