Final answer:
Second degree or reactive thrombocytosis is a condition characterized by an elevated platelet count, leading to an increased risk of thrombosis. It is considered reactive as it responds to some underlying condition or event. Treatment involves managing the underlying cause and monitoring platelet levels.
Step-by-step explanation:
Second degree thrombocytosis, also known as reactive thrombocytosis, is a condition characterized by an elevated platelet count in the blood, which can increase the risk of thrombosis, the formation of abnormal blood clots. It is termed 'secondary' because it is a reaction to another condition, such as inflammation, infection, or cancer. Unlike primary thrombocythemia, which is caused by inherent problems with blood cell production, reactive thrombocytosis is usually a response to another event or condition and is generally temporary.
High platelet counts can lead to an increased risk of blood clots forming within blood vessels, which can be potentially dangerous. These clots, known as thrombi, can obstruct blood flow, leading to conditions like deep vein thrombosis, strokes, or heart attacks if they occur in critical vessels. Reactive thrombocytosis can be caused by a variety of factors including severe infection, chronic inflammatory diseases, iron deficiency, surgery, or as a response to physical trauma.
Treatment for reactive thrombocytosis focuses on addressing the underlying cause. In some cases, when the platelet count is extremely high or the patient has a history of clotting, medications to reduce clotting risk may be prescribed. A healthcare provider will typically monitor platelet counts to determine the effectiveness of treatment and to make sure platelet levels return to normal.
