Recognizing and evaluating hyperthyroidism in pregnancy is a diagnostic challenge. [58] Thyroid hormones are commonly elevated during the first trimester of pregnancy as the pregnancy hormone human chorionic gonadotropin (hCG) stimulates thyroid hormone production, in a condition known as gestational transient thyrotoxicosis.
