Which of the following conditions may result from fetal exposure to maternal hyperthyroidism?

• A. Neonatal hypoglycemia
• B. Craniosynostosis
• C. Maternal obesity
• D. Gestational hypertension

Answer: (B)

Fetal exposure to maternal hyperthyroidism can significantly impact the developing fetus in various ways. One of the notable consequences is the potential for craniosynostosis, which is a condition characterized by the premature fusion of one or more cranial sutures. This can lead to abnormal head shapes and various degrees of neurological impairment due to restricted growth of the skull. Maternal hyperthyroidism affects fetal growth and development as excessive thyroid hormone levels can alter the normal regulatory processes of fetal development. Specifically, the high levels of circulating thyroid hormones, such as thyroxine, can influence cell division and growth patterns in fetal tissues, leading to structural abnormalities such as craniosynostosis. It’s important to note that while conditions like neonatal hypoglycemia, maternal obesity, and gestational hypertension have associations with various maternal conditions, they are not directly linked to maternal hyperthyroidism in the same manner craniosynostosis is. Neonatal hypoglycemia is typically associated with factors like maternal diabetes or significant fetal stress rather than thyroid abnormalities. Maternal obesity and gestational hypertension are complex conditions influenced by multiple factors, including maternal lifestyle and other underlying health issues, but are not primary outcomes of maternal hyperthyroidism. Therefore, craniosynostosis
