Hi,
Welcome to HCM,
Thanks for posting your query,
If you are advised to take Thyronorm 25 microgram then we indirectly know you have underactive thyroid.
You have not mentioned any investigation about Thyroid function which is essential for the diagnosis of
Hypothyroidism, like Free T3, Free T4 and TSH and if TSH value is high generally indicate underactive Thyroid.
some are temporary and some like autoimmune destruction or post surgical may need treatment of Thyroxine supplement lifelong.
Please consult Internal medicine specialist or
Endocrinologist.
Proper history and examination further investigations like
Lipid profile,Serum Prolactin,
Complete blood count,anti TPO antibody and anti thyroglobulin may be done along with
Ultrasonography.
Even if Hypothyroidism is there and proper supplementation is given to maintain Euthyroid state there is no problem in pregnancy only more vigilant and good control of Thyroid is required.
In the meantime continue Thyronorm and take iodized salt with normal diet.
Hope this information is useful to you.
Please take care
Good Luck.
