I've had some weird issues this pregnancy (this is my third bub) and have just had some results back that have indicated I have an underactive Thyroid. The Dr said that it won't effect the pregnancy but I need these tests repeated in 6 - 8 weeks. TSH 0.33 (normal is apparently 0.35)
I also have low iron and low Haemoglobin, tests done in September, repeated last week, show that they are still low so have to keep taking iron + C for at least 3 months after bubs in born.
I am concerned this could deteriorate further and effect bubs, even though Dr said it won't, Internet says it can. I see my midwife clinic this Sat so hoping to ask more qu's then.
Anyone able to give advise on this issue, I would really appreciate it.
I have had problems with hypothyroidism for years. I get my levels checked every 6 weeks atm.
My levels have been really odd during pg, my endocrinologist said that my levels will not affect the baby as babies start producing their own thyroid at the end of the first trimester.
I'm sorry I can't offer any better advice, all I can say is the endocrinologist I see is highly recommended and I trust what he recommends.
I have also got problems with underactive thyroid, but have also been told that the baby starts making its own thyroid after the first trimester so after this the mothers level is less critical. This is why as we haven't got my thyroid replacement levels quite right yet I have a blood test every three weeks but she indicated that once out of first trimester can have BT's 6-8 weeks apart.
The range for TSH I get from my doctor is 0.3 to 5.00 so you would actually be within the normal range according to that.
Is also can get a bit confusing because I thought low TSH means overactive thyroid, as Thyroid Stimulating Hormone gets higher when you have low thyroid e.g. at one point mine was 90 because my T4 was only 5 (should be 9-19), whereas now it is 1.53 and T4 is now right at 14.5. (Often they only check T4 if your TSH is out of range).
I found researching on internet totally confused me and there seems to be so much conflicting info, so like previous poster just trust the endocrinoligist now and fingers crossed scans etc show all ok so far.
A lot of Doctors/labs still use the old normal range of 4mlU/L as the upper limit for normal TSH. However it is easy to find reasearch in the last 5 years that indicates that if TSH is above 2mlU/L, the thyroid gland is in the early stages of disease.
In pregnancy TSH should be:
First Trimester: 0.24-2.99mlU/L
Second Trimester: 0.46-2.95mlU/L
Third Trimester: 0.43-2.78mlU/L
If its above normal ranges there can be all sorts of probs with premature delivery.
I saw my Dr on Thurs and she explained it really well to me. I'm just below their normal at the moment, which means that I might actually have an over active thyroid issue developing (not under active as I thought from what I read on the net). She said that the pituritory gland is the boss, and has slowed down the messages to the thryroid as it's probably working a bit harder to produce the T3/4.
So she'll keep an eye on it, hence the 6 - 8 week blood test. If it keeps going down or is still low, they will then look at the other hormones. Could just be a preggo thing. She said as we have 25% more blood, it could be slightly "watered" down, or it could be the start of something more. But a lot of these abnormalities can just fix themselves once bubs is out.
Made me feel a bit better about it, and will have my next test the week be xmas. Fingers crossed things are looking a bit better. See the obs at the hosp on 27th, so will see if he can check all the 3 hormones this time to give us a better idea on what's possibly going on.
I've been really sick with a cold last week and now have spots, so have more blood tests tomorrow to check for chicken pox etc and see what's going with that!
