During pregnancy, untreated hypothyroidism can lead to which of the following?

Untreated hypothyroidism during pregnancy is associated with an increased risk of various adverse outcomes for both the mother and the developing fetus. One of the primary concerns is the potential for developmental delays in the fetus. Thyroid hormones are crucial for normal neural development and cognitive function. Insufficient levels can lead to impaired brain development, resulting in long-term cognitive deficits and developmental delays.

During pregnancy, the demand for thyroid hormones increases due to the metabolic needs of the mother and the developing fetus. If the mother has untreated hypothyroidism, it can also contribute to complications such as preeclampsia, anemia, and postpartum hemorrhage, which further complicate maternal and fetal health.

Options suggesting benefits for fetal development, higher chances of multiple births, or improved maternal health do not align with the established medical understanding of the effects of untreated hypothyroidism during pregnancy. In summary, untreated hypothyroidism poses significant risks, particularly for the development of the fetus, supporting the selection of the answer indicating an increased risk of developmental delays.
