Hypercalcemia in infant caused by too much vitamin d through breastmilk

by Rebecca
(Torrance, Cali , )

My 5 month old son was recently diagnosed with Hypercalcemia. I am on a 3 month waiting list to have him seen by a pediatric endocrinologist at. Children's Hospital in Los Angeles. I eat a lot of foods high in vitamin D such as salmon 4x a week, egg yolks daily, orange juice with added calcium and vitamin d plus I spend an hour a day in the sun swimming with my 2 year old almost every day. I also give my son 1ml supplement a day plus I am still taking a prenatal vitamin with vitamin d. Could this have caused the Hypercalcemia? His blood calcium test result was 10.9.

Thank you!

Incredibly unlikely
by: Kerri Knox, RN

This is incredibly unlikely unless his vitamin d supplement is either a lot more concentrated than you believe (saying you are giving him 1 ml could mean anywhere between 100 IU's and 75,000 IU's. You have to know how much vitamin d is IN one milliliter for that to be meaningful).

There was a study done of a woman who had a medical condition where she was required to take 100,000 IU's of Vitamin D a day, and she was breastfeeding her baby. The baby never got hypercalcemia.

But to tell if his hypercalcemia is from too much Vitamin D, all you need to do is to check his vitamin D level. You can even get a test done through the mail using a Vitamin D In Home Blood Spot Test. The results would be excellent information to take to your doctor's appointment. Otherwise, your question will not be able to be answered, you'll have to ask for a vitamin d test, then take him to get a blood test, then wait for the results.

In the meantime, you should certainly have him avoid all forms of Vitamin D until you find out what his causing his hypercalcemia and get the OK to start taking Vitamin D again. I'd be curious as to what the cause of his hypercalcemia is. If it IS due to too much Vitamin D, I think you should have his supplement tested. Most Vitamin D overdoses are due to either incorrect amount of supplementation, or the manufacturer creating the supplement incorrectly at the wrong dose. But too much Vitamin D from breastfeeding is so unlikely as to be not worth entertaining the thought.
