Researchers find the time it takes for a Lego head to pass through the body thanks to some brave volunteers. As it turns out, parents do not need to worry that Lego heads will appear in the stool just a few days later.

Inadvertent ingestion

In the new study entitled “Everything is amazing: Do not forget the LEGOs”, a team of pediatricians wanted to know how long a Lego head would pass through the system. This is because among the many foreign objects that children place in the mouth and inadvertently swallows, small toy parts are the second most commonly swallowed object.

To find out, researchers made six adult volunteers who merged from a pediatric community’s health prosecutor. Anyone who has had gastrointestinal surgery, has problems swallowing objects or has “aversion to search through fecal matter” was expelled.

SHAT and FART Scores

All six volunteers devoured a Lego head and held a “fecal diary.” Before and after swallowing the Lego head where the documented frequency and unloading of their stools based on pallet hardness and transit points (SHAT). After shutting down the Lego head, every volunteer has to be sifted through his own fecal matter to determine if the toy had already passed. The time it took before the Lego Head was downloaded was dubbed FART or Found and Retrieved Time.

As it turns out, parents worrying that their children are killing a Lego head need not worry too much as five of the volunteers’ FART points ranged from 1

.14 days to 3.04 days, with an average of 1.71 days or 41 hours.

As mentioned, researchers noted that this is a small study focused on adults instead of toddlers, and that small toys of different shapes could take different amounts of time to pass. One of the volunteers never retrieved the Lego head.
