5 weeks pregancy with very low TSH and high T3 & T4

[DummyMom]

I'm 37 years old and ~5 weeks pregnant. I have tummyache sometimes these several days feel like my period is coming soon. I also feel thirsty and can't sleep well at night. Even though I eat normally, I have lost 7 lbs since Jun 15. I'm afraid of cold. Do not vomit in the morning. My heart rate is ~80 beat/minute. Am I seriously hyperthroidism? I'm still waiting for my family doctor referral for an endocrinologist. Did it hurt my baby already even if I get proper treatment now?

You are hyperthyroid they should have ordered propylthiouracil - PTU to take. Of the "anti" drugs this one is safest to take while pregnate.

YOU NEED TO START IT ASAP...if they didnt order it and are making you wait for the End. Get back on the phone and hound them. NOW.

All your symptoms are common pregnacy symptoms - most just happen to be hyper T symptoms too so it can be difficult to decifer which is from what.

I have gone through two hyperthyroid pregnancies. I have to two beautiful children with no problems.

I understand the scared part. It was something else to face and deal with.

Most important get your hyperT treated...Do not play:"I'm gunna protect my baby and not take anything"

The potentiual medication side effects to the baby are reversable...the damage untreated hyperT can do to you is NOT.

Hypert T can cause miscarrage (miscarriage) in the first and third trimesters.

Hyper T babies sometimes just stop growing.

Possible PTU side effects for baby (which develop later in preg)...supressed thyroid function and fetus develops a goiter (may require a C-section if large enough, will reverse itself after deliver).

They will run thyroid tests on the baby at birth then a few weeks later to make sure their thyroid is functioning. They dont test them anymore if those are normal even if you are breastfeeding and still on the PTU (the amount that crosses over in breast milk is mute)
I had mine tested just for peace of mind during nursing and they were always within normal limits.

You can expect to have more ultrasounds then normal with this diagnosis to monitor fetus growth and to watch for goiter.

Good luck on your pregnancy

Peace be the journey
