Hi Practo user,
Thyroid hormone is a growth hormone. It's demand is increased during pregnancy,so generally the
TSH level reaches upper limits or beyond that. 4.67is the upper limit, you must be prescribed 25mg because TSH levels are borderline. You don't need more than this. Thyroid hormone helps normal growth of the foetus. Take it regularly during pregnancy as prescribed. You might not be needing it post delivery. For further queries and treatment connect directly through Practo consultation.
