Immune thrombocytopenic purpura or ITP is an autoimmune condition in which the body produces antibodies against its own thrombocytes or platelets, which are destroyed. And this result in purpura, or small bleeding spots beneath the skin.
Normally, when there’s any kind of damage to the blood vessel, hemostasis occurs, which is the process that stops the bleeding and plugs the damaged vessel to limit the blood loss.
Then, fibrin forms a protein mesh, kinda like a giant net that covers the platelet plug and stabilizes it.
This leads to lowering of platelet counts in the blood, which makes it harder for bleeding to stop. Now, ITP can be acute or chronic.
