I am about 8wks now and I have Hashimoto's Thyroiditis (underactive thyroid). I had no issues with my first pregnancy but my TSH was 5.0 and they are sending me to the endocrinologist to get my synthroid levels increased. I have been SO tired and really groggy and I have been feeling like my heart is racing from time to time. Just wondering if anyone else had to adjust their dose with pregnancy?<br>
TIA

Yes. I had to adjust my dose several times. Please make sure you get this checked every 2 months or so as low thyroid can lead to problems for baby.<br><br>
I actually had the largest fluctuations in dosage AFTER dd #1 was born. Got much worse.<br><br>
Make sure you keep this under close watch and control post baby too as it can have an effect on milk. I have never had any problems though.<br><br>
Congrats!

I've always had to increase my dose during pregnancy... going from 75 mcg or so to usually 100 or 125 mcgs. It's normal. I think for me, we checked it every trimester, once we got the meds sorted out.

oh hon --<br><br>
get it checked monthly. my prescription went from .25 (mcg?) of levoxyl at the beginning of pregnancy to the current level of 100!<br><br>
every month my tsh got higher and higher and i was adamant about keeping it as close to 1 as possible. its at about 2-3 right now, even though the doc says "up to 5 is normal" i would rather keep it closer to 1. thats what all the new studies advise anyway<br><br>
good luck!!

I haven't been through a pregnancy yet, but I have Hashimoto's and had a complete thyroidectomy. The plan for when I get pregnant:<br>
The day I get a postive test we increase my dosage to 1.5 times the current level.<br>
then I get bloodwork done every 2 weeks for the duration of the pregnancy and for as long after as it takes to stabilize thereafter. It takes 6 weeks for a change in dosage to be fully reflected in bloodwork, but by then your level may have changed too much. So its a bit of a guessing game even with regular bloodwork.<br><br>
We keep my TSH between .1 and .3 to keep the cancer from coming back, so even if it goes up slightly it would still be in a reasonably healthy range for the fetus, but the doc is still recommending this aggressive plan because your thyroid supplement needs can increase dramatically during pregnancy.<br><br>
A level of 5 is insanely high. While it would have been considered slightly elevated under the old standards, the new standard of care is to keep your TSH much lower. Most endos I've met think anything above 2 is too high and the target should be 1.

Mine gets checked every month (I have hyperthyroidism), but oddly enough, this pregnancy has knocked me back into the normal range without medication.

I also have hashimotos, during my pregnancy I have been seing an endocronologist to monitor my levels instead of my regular dr. I have went from 125 mcg to 175 mcg. synthroid. I felt the same way as you do in the beginning of my pregnancy. After my levels were adjusted I felt much better. Good luck!

Also hypothyroid, VERY common to require an uptake in your synthroid. I went from 50mcg to 100mcg, they should retest you a couple of times during pregnancy to make sure the dose is all right.<br><br>
My GP said it takes about 3 months after pregnancy for it to settle back down so he didn't recommend a retest until then--I just got round to having it done <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/blush.gif" style="border:0px solid;" title="blush">

Hi<br><br>
I'm also hypo and on Synthroid. I'm 11 wks pregnant. My dose has already been increased once.<br>
My endocrinologist recommends TSH be kept between .5 and 1.5 during pregnancy. She's going to see me every four weeks, which I appreciate because my last endo would only see me every 6-8.<br><br>

Thanks so much for your replies! My last pre-preg levels were 4.5 (which is actually high for me). I like to be around a 2. Last pregnancy had me at 3.7 and I was fine.<br>
Now I'm taking 112mcg. Do you think they will increase it sort of slowly? I'm just nervous to skip to taking more then 125. The symptoms of thyroid disorder are so complicated and I know once my levels are adjusted I will feel tons better. Today I slept from 2-5:15 without skipping a beat and I'm still exhausted. Can't wait to see the endo on Thursday. I'll update you then.<br>
Thanks!

I had my levels checked during each trimester. I had to have my levels increased during the second trimester. It did help with the fatigue.

I tend to be stable during pregnancy but post partum...the thyroid roller coaster takes me for a ride for about 6 months.<br><br>
I agree, keep monitoring it. If you feel like things are off, don't wait!

So I saw the endo today. He was GREAT! I was so anxious!!!! My heart rate was 120 when they took it <img alt="" class="inlineimg" src="/img/vbsmilies/smilies/loveeyes.gif" style="border:0px solid;" title="Loveeyes">: , but BP was really fine (110/70). He was really informative and listened and stated that he is usually really aggressive with treating pregnant thyroid patients but that he understands based on my history that we should increase slowly so I went from 112mcg to 125mcg with a TSH of 5.05. I am so pleased! I was terrified that he would jump me up much higher. He also felt my thyroid (which the midwife freaked out about and called a goiter) and he said that it is just mildly enlarged as he would expect for someone with Hashimoto's. He also said I have a very slender neck which might make someone without specific traning overestimate the size. Very reassuring and I am excited to start my new dose tomorrow so I can start feeling better.<br><br>
PS-my pulse was much lower in the car, like 90, which is totally normal for me <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/lol.gif" style="border:0px solid;" title="lol">
