I coughed up blood.
tos-SI-to — three syllables, stress on second. 'Sangue' — SAN-gwe. Past participle construction.
Report haemoptysis to a doctor immediately — this is always a serious symptom requiring urgent investigation.
'Ho tossito del sangue' = I coughed up blood (haemoptysis). 'Emottisi' is the medical term. Even a small amount is significant. Causes include: lung infections (TB, pneumonia), bronchitis, lung cancer, pulmonary embolism, or heart failure. Do not confuse with blood from the mouth or nose — haemoptysis specifically comes from the respiratory tract.
C'era sangue nel catarro.
There was blood in the phlegm.
Blood mixed with mucus — typically seen in bronchitis or early infection
Ho sputato sangue rosso vivo stamattina.
I spat up bright red blood this morning.
Bright red blood — more concerning, may indicate significant bleeding
Non so se il sangue viene dai polmoni o dallo stomaco.
I do not know if the blood is from the lungs or stomach.
Important distinction — haemoptysis vs haematemesis have different causes and urgency
Lung cancer ('tumore del polmone') is the leading cause of cancer death in Italy. Italy has one of the highest smoking rates in Europe — though declining. Italian oncology guidelines recommend low-dose CT screening for high-risk smokers (age 50-80, 20+ pack-years). Tuberculosis ('tubercolosi') has resurged in Italy among homeless populations and recent immigrants — Italian public health monitors TB cases through 'notifica obbligatoria' (mandatory reporting).
