What is microthrombi?

Microthrombi are tiny clots that form inside blood vessels, like little traffic jams in the road of your blood.

Imagine your blood is like a busy highway with cars (red and white blood cells) zooming along. Sometimes, pieces of the road get sticky or damaged, and some plates, think of them like little sticky notes, jump into action. They stick together and grab on to other parts of the road, creating a small blockage.

It's kind of like when you drop a chocolate chip into your milk, it might not stop the whole drink from flowing, but it makes some parts slower or even stops them completely. That’s what microthrombi do: they slow down or stop blood flow in small parts of the body.

These tiny clots can happen anywhere, in your legs, lungs, or even your brain. Sometimes they cause no problem at all, and other times, they can help doctors find out if something is going on inside you!
