Common endocrine issues in Williams syndrome: What you need to know

Treatment (for both conditions)

• Regular blood and urine tests
• A diet that is low in calcium. This means no more than 3 servings of dairy or calcium-fortified foods (foods with calcium added) per day. If you would like to give your child a multivitamin with calcium, please ask the care team for recommendations. Your child will need regular blood tests throughout their life to check their calcium levels and bone density (the amount of material in the bones).
• In rare cases, your child might need more medical care for issues caused by hypercalcinemia. This usually happens if your baby is not feeding well or gets sick. After treatment, calcium levels usually return to normal.
• In some cases, your child might need a renal ultrasound (kidney ultrasound). This helps make sure calcium is not collecting in the kidneys.
