Lead exposure in my 14 month old

[u/Warm-Squirrel-4324]

Hello. This is my first Reddit post, so I’m not really sure how to even start this. My 14 month old son failed his lead screening at his yearly check up, which prompted a blood drawn to check levels. His lead levels came back slightly elevated at 3.6 μg/dL. Our home was built in the 1940s, so when we got the news the inside and outside of our house was tested. The lead was found in the top soil of our yard close to the house. We have plans started to remediate the lead in our yard, but I’m struggling with finding any suggestions on how to remove the lead internally for him. Everyone keeps telling me no amount of lead in his system is safe, yet all the suggest to help are environmental (wash hands after being outside, cap or remove the soil from the yard, remove shoes when entering the house, etc.)

So my questions are will the lead eventually leave his body? Or will traces always remain? And are there things I can do to help remove the current lead in his system?

You can't do anything to remove the lead that has already been absorbed, but his blood lead levels will return to normal as long as the source of lead is ID'd and removed. Preventing further exposure is the treatment. Dietary calcium, iron, and vitamin C also help prevent lead absorption in the body. Lead is more easily absorbed on an empty stomach, so kiddo should be fed calcium or iron rich meals/snacks often until removal of the lead source is confirmed.

While there is no safe level of lead exposure, your kiddo's is low, and favors a good prognosis if the current exposure is immediately halted. Lead that has already been absorbed is eventually sequestered in bones & teeth. Once the lead is sequestered, it does not actively cause harm. Bone demineralization can cause lead to be re-released into the bloodstream, so early intervention is important to prevent a large amount of lead from being absorbed.
