Thrombocytosis generally has little impact on life expectancy if the disease is well controlled and has no serious complications, but can affect life expectancy if the disease is poorly controlled or progresses rapidly.
Thrombocythemia is divided into reactive thrombocythemia and idiopathic thrombocythemia, in which reactive thrombocythemia will return to normal after controlling the related disease factors, and will not lead to shortening of life expectancy.
Patients with idiopathic thrombocythemia need to be actively treated for the underlying disease, which often requires lifelong treatment; the impact of the disease on life expectancy varies with the type of blood disease in different patients; generally, if the disease is properly controlled, the impact on life expectancy will be small.
A small percentage of thrombocythemia can turn into other types of myeloproliferative tumors, which can have an impact on life expectancy. If you have any discomfort, you should consult your physician for prompt medical attention.
