How much does levothyroxine increase?
The percentage increase in levothyroxine dose needed can be as high as 30–50% and is highest when the cause of the hypothyroidism is a thyroidectomy or ablation of the thyroid gland . Achieving a serum TSH < 1.2 mIU/l preconception seems to reduce the percentage of patients requiring a dose increase .
Why does thyroxine increase during pregnancy?
Higher levels of thyroid hormone are needed during pregnancy and, in women with normal thyroid function, the thyroid gland increases the production of thyroid hormone to meet this increased need. In hypothyroid women, this often means that the dose of Levothyroxine needs to be increased during pregnancy.
Can thyroid affect baby growth?
Early studies found that children born to mothers with hypothyroidism during pregnancy had lower IQ and impaired psychomotor (mental and motor) development. If properly controlled, often by increasing the amount of thyroid hormone, women with hypothyroidism can have healthy, unaffected babies.
Can my thyroid affect my pregnancy?
There is greater risk to the pregnancy from an untreated over-active thyroid gland than from taking antithyroid medication. Untreated hyperthyroidism can also lead to complications of high blood pressure in pregnancy, poor growth of the baby and premature delivery.
What is ideal TSH for pregnancy?
However, the definition of a normal TSH during pregnancy has been changing over time. In 2007, The Endocrine Society recommended that all women on thyroid hormone replacement therapy (levothyroxine) have TSH less than 2.5 mIU/L during the first trimester and less than 3 mIU/L throughout pregnancy.
What is a good thyroid level for pregnancy?

How can I lower my TSH naturally during pregnancy?

Joint and muscle weakness and pain, especially in the arms and legs, can be evidence that you need an increased dose of antithyroid drugs for your hyperthyroidism.
Is 25 mcg levothyroxine a lot?
There are two strategies for initiating levothyroxine in healthy adults younger than 65 years: low-dose (50 mcg) and full-dose (1.6 to 1.7 mcg per kg). Traditionally, lower starting doses of 25 to 50 mcg per day are recommended for patients 65 years and older or who have ischemic heart disease.
