Hi Sredevi

You don't give any medical history on your profile so I assume you are diagnosed - with hypothyroidism? Were you diagnosed after pregnancy or before?

This is a link which may be helpful and read from the third question onwards. Do you have the ranges of your blood tests (the figures are in brackets) as it makes commenting easier.

This is a quote from Dr Toft who was President of the British Thyroid Association.

Untreated maternal hypothyroidism results in neuropsychological damage to the offspring. Patients with hypothyroidism who become pregnant need to have the dose of levothyroxine increased on average by 50µg daily in order to maintain normal serum TSH concentrations.

The advice to patients with established hypothyroidism is that they should increase their dose of levothyroxine by 25µg daily as soon as pregnancy is confirmed and make an appointment for thyroid function tests to be measured some two weeks later. The aim is to achieve a free T4 concentration of 16-20pmol/l.

Further measurement of serum free T4 and TSH should be made six weeks later and again in the middle of the second and third trimesters.

The pre-pregnancy dose of levothyroxine can be restored four weeks after delivery by which time the increased concentrations of thyroxine binding globulin will have returned to normal. It’s not clear whether this meticulous care is necessary and it may well be that any thyroxine therapy in the hypothyroid mother will allow normal foetal development.

Dr Tony Toft is consultant physician and endocrinologist at the Royal Infirmary of Edinburgh, and a former president of the Royal College of Physicians of Edinburgh and of the British Thyroid Association

I was diagnosed hypothyroidism 2 years before & I have been taking medicine of eltroxin 50mg regulary & i was diagnosed before pregnancy

[shaws Administrator in reply to sridevi]

50mcg is usually a starting dose and your GP should increase due to your pregnancy.

If you can ge a copy of your most recent thyroid gland blood test results with the ranges and post on a new question, someone will comment just in case you have been undertreated and explain you are now pregnant.

Hi Sridev

Shaws is right that you should have an increase in thyroxine (if you are taking it) during pregnancy. I presume your T3 is 2.6, which could be on the low side and your TSH could be high. You should probably be treated if you are not already being treated.

Also I just wanted to say that my hypothyroidism was not properly treated during my pregnancies, and my babies were both fine. However, it would be good to get treated properly. I just wanted to say that even if you haven't been treated optimally, you can still have a perfectly OK baby, so you are not too concerned about what has already happened.

You may find you have a rather large baby also!

I hope you are able to find a physician to help you.
