In brief: Many things.

High platelets can occur with bleeding, iron deficiency and inflammatory conditions such as rheumatoid arthritis.
They can be high due to a blood disorder (myeloproliferative neoplasia). Platelets also can be elevated in response to serious illnesses. The cause should be investigated, found and if possible treated.
