Final answer:
Second degree thrombocytosis, or reactive thrombocytosis, is associated with conditions that cause an increase in platelet counts, such as inflammatory diseases, iron deficiency, certain cancers, and tissue damage, and can lead to an increased risk of thrombosis.
Step-by-step explanation:
Second degree thrombocytosis, also known as reactive thrombocytosis, is associated with a variety of conditions that can trigger an increase in platelet counts. Unlike primary thrombocytosis, this reactive form does not originate from abnormalities within the bone marrow itself, but is a response to other factors or conditions. These include inflammatory diseases, such as infections or chronic inflammatory disorders; iron deficiency; certain cancers; after surgery; or as a result of hemolysis or tissue damage. It's important to address the underlying cause of reactive thrombocytosis to prevent thrombosis, the excessive formation of blood clots that can have severe health implications, including increased risk of stroke or heart attack.
