Patients with Hashimoto’s hypothyroidism are able to have healthy children, but generally need to have normal thyroid control before becoming pregnant, otherwise it can lead to problems such as miscarriage and fetal malformations. Pregnancy is not recommended when hypothyroidism has not been corrected, and patients are required to take levothyroid hormone and become pregnant only after thyroid function is normalized.

In summary, patients with hypothyroidism can also have a healthy child, it is recommended to take medication under the guidance of a doctor, regular monitoring of thyroid function during treatment, and timely adjustment of dosage.
