Thryoid and miscarriage

[Sleeplessin2023]

Last year I had three miscarriages, last one at start of December. I've had a load of tests since then and all came back normal, except my thryoid which was sub optimal for fertility with a TSH of 3.5. Doctors can't say if it's responsible for miscarriages as apparently its not that high but still not ideal and worth treating b4 trying again.

I've been put on what appears to be a low dose of levothyroxine at 25mg.

My heads all over the place, grieving but on one hand also hoping that the thyroid is the problem and is fixable and wanting to get pregnant asap but terrified of getting pregnant and losing another baby.

I've a ton of questions in my head and hoping someone who reads this has some advice :

• has anyone been in a similar position and had multiple miscarriages potentially caused by thyroid? What was yr tsh? Did u go onto have healthy pregnancy?
• has anyone been prescribed 25mg levothyroxine? Did it make any difference to ur tsh or did u need a higher dose? How long were you on levothyroxine before your tsh levels improved?

Thanks for reading

I'm sorry for your losses, that sounds extremely hard. I've had trouble conceiving and an early term miscarriage and have hypothyroidism caused by hashimoto's disease. My TSH is 1.34 and I take 125mg levothyroxine a day. It's important to get your GP to run a full thyroid panel, including TPO antibodies, ft4 and ft3 as TSH is just one part of a much bigger picture. TSH should be as close to 1 as possible and I'd recommend cutting gluten, dairy and soya from your diet as these can cause inflammation and increase your TPO antibody count (high TPO has been linked to increased risk of miscarriage in the first trimester) as well as making it more difficult for your body to get the nutrients it needs from the food you eat. GPs know next to nothing about any of this and you're best off speaking to a functional medicine practitioner, or an endocrinologist who specialises in fertility. Good luck x

Thanks for replying . is there any particular diet that you follow like paleo etc?

I follow a more relaxed version of AIP, which means for me no dairy, gluten, soya, refined sugar, or alcohol, and very few grains like rice. I also take a lot of supplements (iron, magnesium, zinc, vitamin D, calcium, selenium, folic acid, biotin, l-glutamine, probiotics, prebiotics, and thiamine). Everyone is different though and what you choose to do should be in accordance with your individual needs and symptoms x
