###Human: Can I continue my pregnancy with a high TSH level? ###Assistant: Hi. Yes, you are right. Hypothyroidism can affect the fetal brain development, especially in early pregnancy. Thyroid hormone is normally very important for many functions of the body. It helps in the early development of the fetus. The brain is one of the parts of early organ development. In early pregnancy, fetus mainly depends on mother's thyroid level because fetus itself cannot produce up to around 11 to 12 weeks (three months). There is no data available whether you have taken treatment early and adequately. But yes, there is data that hypothyroidism can affect brain development and function in baby permanently and whatever damage occurs is irreversible. If you are taking Thyroxine (Levothyroxine) 50 mg and the level is this high, then you need to increase the dose. And, if you have started treatment just now, then continue and repeat according to the doctor. For further information consult an obstetrician and gynaecologist online -->
