Reactive Thrombocytosis

Reactive thrombocytosis occurs when your body produces too many platelets—a type of blood cell involved in clotting—as a response to another condition, such as infection, inflammation, anemia, or tissue injury. It is not caused by a disorder of the bone marrow itself. This increase in platelets is usually temporary and part of the body's healing process. While elevated platelets can raise the risk of abnormal blood clots, reactive thrombocytosis generally resolves once the underlying condition is treated or improves. Monitoring and managing the primary cause are key to controlling platelet levels.
