Brief Answer:
TSH has to brought below 2.5

Detailed Answer:
Hi XXXXXXX

Welcome back to HCM.

Your TSH is slightly high. The doctor has appropriately increased the dose. Please recheck a T4 and TSH after 1 month and adjust dose based on the values.

Regarding your other questions

1. Adverse outcomes in baby

Chance of miscarriages and preterm delivery are higher in hypothyroidism - you only have mild hypothyroidism ( subclinical hypothyroidism ). The chance of these decrease with treatment.

Congenital anomalies are not with any increased risk.

IQ - slightly low in some studies, normal in others.

So there will be no significant abnormalities in your child other than doubtful effect on IQ ( Brain development ). There are studies involving more than 1000 mothers in which IQ was normal in babies born to hypothyroid mothers compared to non hypothyroid mothers.

2. Hypothyroidism in baby

If you are having hashimoto's hypothyroidism ( high anti thyroid antibodies in blood ) there is a chance of transient hypothyroidism in baby which can easily be detected in newborn screening and treated.

Mother's hypothyroidism is usually not transmitted to babies as congenital hypothyroidism. But since your genetic make up is similar, the child is at risk for hypothyroidism.

Hashimoto's hypothyroidism usually run in family.

Hope this will clear your doubts. Trust me, since you are having only subclinical hypothyroidism and treated properly, if you go for term delivery, you will be having a healthy baby.

Doctors give much importance to thyroid disorder ( and possibly scare you ) because it is an easily treatable condition and we can prevent miscarriages and pre term delivery.

Brief Answer:
Congenital anomalies are birth defects

Detailed Answer:
Hi,

Welcome back

Congenital anomalies are birth defects - like heart disease, or any deformities. There is no increased risk reported that the baby born to a hypothyroid mother can have congenital anomalies.

IQ (Intelligennt quotient) is a function of brain development. The reports on IQ babies born to hypothyroid mothers are not clear. Some studies say that there can be a mild decrease in IQ, some say there won't be.

Low IQ will be seen in severe hypothyroidism and not is mild decrease in thyroid function as in your case.

Any how now your baby's thyroid gland will be producing enough thyroid hormones for his brain development. ( Babies start producing thyroid hormones from 20 weeks)

Regards.
