Hello...Good morning.

i wants to know that, my wife have a Hypothyroidism 4.40 (TSH) showing in medical report. we wanted to plan for family planning from next month. currently she is taking 50mg power Thyroid control medicine. Can anyone suggest weather we should plan in this situation or we should wait until Hypothyroidism level reduced less than 3.

  • Welcome to our forum,

    It's 10 pm in the UK. First your wife's TSH is too high and the doctor should increase her medication until her TSH is in the low-normal range. This is an excerpt that another Admin replied to a very similar question:-

    Hypothyroidism can cause temporary infertility but when optimally medicated you should be able to conceive. In the UK it is recommended that the TSH of women planning to conceive should be in the low normal range 0.4-2.0. TSH >2.0 can make conception difficult and increases the risk of miscarriage. Levothyroxine is usually increased by 25-50mcg when pregnancy is confirmed as the foetus is dependant on maternal hormone during the first trimester.

    Your wife should also have her Vitamin B12, Vitamin D, iron, ferritin and folate checked as well.

    When she goes for a blood test for thyroid hormones, it should be done as early as possible, she should not eat before it and supplements should be taken 4 hours apart from levothyroxine. Levothyroxine can be taken after the blood test but if she has something to eat after her blood test 2 hours should be allowed before and after she takes levothyroxine so that food will not interfere with the uptake.

    I hope everything goes well.

  • well thank you very much for the reply. She had taken dinner before that blood test. So may be it shows little high. I will test again with empty stomach.

  • That's good and if possible the blood test should be as early as possible. The reason is that the TSH (which doctors diagnose on) will be higher early morning and then your wife might need an increase in levothyroxine.

  • Hari, if she had dinner before the blood test, it would be showing LOWER than it really is. TSH lowers during the day - therefore the test should be done about 8.00 am, and it lowers after eating. You want it to be as high as possible, otherwise, she will not get the increase she needs. :)

  • This is another helpful site.


  • her TSH should be less than 1 and she should feel 100% well before you think about starting a family

    Also if as I suspect your wife is hypothyroid due to Auto immune Hashimotos Disease please think very very carefully about the genetic consequences

    My husband , our daughter and 4 of 6 grandchildren plus a nephew all have Hashimotos hypothyroid

  • Thank you very much for the reply. She is feeling perfectly fine. And her weight is also constant. neither increasing nor loosing. I think i should do one more time blood test with empty stomach. It was done after dinner.

  • I think you misunderstand a little. It's best to take the thyroxine medication on an empty stomach, so it is absorbed well. It doesn't matter if you have eaten before the blood test.

  • It has been found recently that an empty stomach is best when having a blood test. I will try and find the link.

    It is correct about taking it on an empty stomach.

  • yes she is taking medicine in the morning with empty stomach. But my query is that i should do blood test with empty stomach or not?
