Many women have explained to me that their doctor did not feel the need to increase their thyroid hormone dosage. This led to a miscarriage because of the imbalance of thyroid hormone. The amount of hormone needed increases when pregnant because you need to provide for the baby too.
When you take thyroid medication you block your thyroid from doing the job to naturally produce thyroid hormones. That means if you take thyroid medication you need to make sure it doesn’t need to be adjusted. Most women need to increase the dosage of medication.
How Much Hormone Will Your Thyroid Need?
This all depends on the mom but many women need to increase their dosage by 40% to 100%. Meaning if you are taking 50mcg (Synthroid or Levothyroxine) you may need to increase it up to 75mcg.
Do not be hard on yourself if you have to increase your dosage as it is needed for you and your baby. Most importantly you should out find if you need to increase it as soon as possible. The first trimester is when your baby needs it the most. So making sure to find this out in the first trimester is so important.
