View source for Secondary polyglobulia

'''Secondary polyglobulia''' is mostly compensatory in ''chronic hypoxia'' (leads to ↑ [[Erythropoetin|EPO]]) when staying at high altitude, chronic lung disease, right-to-left shunts, methemoglobinaemia.

Less often, the cause of ↑ EPO is unclear/a manifestation of a disease ([[kidney tumors]], [[uterine myomatosis]], [[polycystic kidney disease]], etc.).

=== The clinical picture ===
* mainly symptoms of underlying lung/heart disease,
* plethoric appearance, [[cyanosis]],
* [[headaches]], [[dizziness]], [[visual disturbances]].

=== Laboratory Tests ===
* ↑ erythrocytes, HTK > 48%, oxygen saturation <92%, ↑ EPO (dif. dg. [[Polycytaemia vera]]).

=== Therapy ===
* Th. of underlying disease, [[venipuncture]] (↓ blood viscosity + reduces the risk of complications).<ref>{{Cite  |type = book |surname1 = Klener |name1 = P |collectiv = yes |title = Vnitřní lékařství |edition = 3 |place = Praha |publisher = Galén |year = 2006 |pages =  |isbn = 80-7262-430-X }}</ref>
