Thyroid dysfunction is very common and much more so in women than in men. It comes in 2 district forms , an under active gland ( hypothyroidism ) or an overactive gland
( hyperthyroidism ). The presence of either condition is NOT a contraindication to pregnancy , but pregnancy loss or sub fertility & infertility has been recognised retrospectively in patients who are not optimised on their treatment .
It is imperative that particular TSH targets ( the TSH is a marker of thyroid function ) are achieved and maintained in steady state. Once that it is established, the ' thyroid environment ' is optimal for pregnancy .
When the patient is pregnant however , there are further dose / medication adjustments needed in whatever one may be taking ( Eltroxin in the Hypothyroid patient / Neomercazole in the hyperthyroid patient) , and so it is recommended that you see an endocrinologist for ongoing care
