Literally meaning: “inflammation of veins”
Origin: Anc Greek
φλέω/phleo(=be fruitfull or plentiful)
+ (-ίτις)/-ιτις (=-itis, suffix meaning “pertaining to” or “inflammation”.) It is in feminine gender because it was used with feminine noun η νόσος/ e nosos /(=disease)
German physician Rudolf Virchow(1821-1905) who coined the terms thrombosis and embolism disproved the previous theory that phlebitis causes most diseases.
Phlebitis is the inflammation of leg or arm veins caused by various factors such as smoking, obesity and pregnancy.
