Down syndrome is associated with which systemic conditions?

• A. Congenital heart defects and thyroid issues
• B. Kidney stones and migraines
• C. Celiac disease only
• D. Diabetes insipidus

Answer: (A)

Down syndrome commonly comes with several systemic conditions, and the most consistent pairing among the options is congenital heart defects alongside thyroid issues. Heart defects are among the most frequent congenital problems in individuals with Down syndrome, with atrioventricular septal defect being a classic example. Thyroid problems, especially hypothyroidism (often autoimmune), are also common in this population. While there is an increased risk of other conditions like celiac disease, kidney stones, migraines, or diabetes insipidus, those are not as characteristic or widely recognized as the combination of heart defects and thyroid disease. Therefore, the pairing of congenital heart defects and thyroid issues best reflects the typical systemic associations seen with Down syndrome.
