Yes, raised TSH suggests uncontrolled hypothyroidism
which would definitely have an impact on your baby and pregnancy
It can lead to miscarriage
, still birth, death of baby in uterus, growth restriction, mental retardation and low IQ of the baby.
Also difficult labor and prolonged bleeding are seen in untreated cases of hypothyroidism.
Inorder to ensure safe pregnancy outcome you have to start thyroxine replacements to normalize your TSH levels. Consult an endocrinologist
for the required dose and drug.
4-6 weekly monitoring of TSH levels is required once you start the treatment.
In pregnancy the TSH levels have to be kept below 2.5 mU/L in first 3 months and then below 3 mU/L in later pregnancy.
Thyroxine replacement drugs like thyronorm
are safe to use in pregnancy. So you need not worry about the harm caused by the drugs to the baby.
