Chronic smoking can lead to heart failure, chronic lung disease, etc., and hence, polycythemia occurs. It is called secondary polycythemia. With the treatment, the prognosis is good in secondary polycythemia.
But, polycythemia can occur as primary polycythemia as well, and in that case, the prognosis will not be good as it is considered under myeloproliferative neoplasm.
Primary polycythemia called polycythemia vera and for that JAK2 mutation study done by a molecular method to confirm it.
For polycythemia, the treatment is therapeutic phlebotomy in which 250 to 400 mL of blood is removed as per needed frequency.
Our aim is to maintain HCT - hematocrit of less than 45% in polycythemia male patient.
Initially, phlebotomy can be somewhat aggressive with more frequency and then maintained as less frequency. Hydroxyurea drug has proven effective in polycythemia.
Consult a nearby physician for examination with keeping all this in mind and stop smoking as soon as possible.
