Osmosis video - Heparin-induced thrombocytopenia

Heparin-induced thrombocytopenia (HIT) is a rare but potentially life-threatening complication that can occur during the treatment course with heparin. HIT occurs when the body produces antibodies against heparin, which then attach to and damage platelets (the cells that help the blood clot). This can decrease the number of platelets in the blood (thrombocytopenia), which can cause easy bruising and bleeding.
