TSH levels when trying to conceive?

[Jhenderson]

Can anyone tell me what range your bloods have to be when trying to conceive? TSH was 12 they increased my dose to 100mg now it's 2.2.

Thanks

Hi j, Your TSH should be around 1.0 Yours may be too high still at 2.2

Your progesterone is also important, right? If your thyroid levels aren't good it stresses the adrenals and then adrenals steal progesterone to make cortisol I think. Make sure to supplement magnesium and vitamin C for the adrenals.

I agree with Heloise. IN fact several women locally took progesterone after having miscarriages and got pregnant and kept the baby. you also need to know what your free t3 free t4 is to make sure you are coverting....

Thanks Heloise for your reply. Booked a doctors appointment to discuss increasing my dose. X

Do you have Hashimoto's, also called autoimmune thyroid disease. Have you had thyroid antibodies tested? If not get them checked

Also previous post 6 months ago you had low vitamin D. Have you been supplementing and had level rechecked

What about ferritin, B12 and folate too. They all need to be at good levels for thyroid hormones to work. Always get actual results and ranges

If you have Hashimoto's then really need to consider trying strictly gluten free diet

Thank you for your reply. Can you tell me how thyroid antibodies affect you when your trying to conceive? Does it really matter knowing your antibody levels if you TSH is in range?

Fertility dr happy with vitamins levels. Xx

Doctors are happy with vitamin levels which are in range, and some of them are happy with levels which are a bit below range, the attitude being "that's close enough". However being in range, or close to the range isn't the same as being optimal.

You should really find out

a) Which vitamins and minerals have been tested

and

b) What the results and reference ranges are.

Once you have them, post on here and ask for feedback. The ones that most often tend to be low in people with thyroid disease are iron/ferritin, vitamin D, vitamin B12, and folate.

Just about everybody knows that pregnant women need good levels of folate, but did you know that low vitamin D in a pregnant woman can have a bad effect on bone health in the developing child? Or that low vitamin B12 has been shown to increase the risk of neural tube defects and hydrocephalus (but, admittedly, only in rats - it is an unethical experiment to run in humans)?

Many doctors seem to think that vitamins and minerals are of low importance. They get no training in nutrition at all. But you can help yourself before conception if you want to, and you will benefit too.

JHenderson,

TSH of women planning pregnancy should be in the low-normal range of 0.4 -2.5. When pregnancy is confirmed dose is usually increased by 25-50mcg to ensure good foetal development.

NICE recommends hypothyroid women planning pregnancy should be referred to endocrinology for management.

cks.nice.org.uk/hypothyroid...

Management of primary hypothyroidism: statement by the British Thyroid Association Executive Committee

13. The serum TSH reference range in pregnancy is 0·4–2·5 mU/l in the first trimester and 0·4–3·0 mU/l in the second and third trimesters or should be based on the trimester-specific reference range for the population if available. These reference ranges should be achieved where possible with appropriate doses of L-T4 preconception and most importantly in the first trimester (1/++0). L-T4/L-T3 combination therapy is not recommended in pregnancy (1/+00).

If you have Hashimoto's then you need to see how high antibodies are and look for the reason or root cause, usually gluten and/or dairy intolerance

See The Thyroid Pharmacist website for masses of info about Hashimoto's, including fertility and pregnancy
