| '''Hemoptysis''' or '''haemoptysis''' (see [[American and British English spelling differences#Simplification of ae .28.C3.A6.29 and oe .28.C5.93.29|American and British spelling differences]]) is the expectoration ([[cough]]ing up) of [[blood]] or of blood-stained [[sputum]] from a source below the vocal cords such as the [[bronchi]], [[larynx]], [[vertebrate trachea|trachea]], or [[lungs]] (e.g. in tuberculosis or other respiratory infections). It is not the same as [[hematemesis]], which refers to [[vomit]]ing up blood. | |

| |
|
| ==Pathophysiology==
| | {{CMG}}; {{AE}} {{SSH}} |
| In most cases of hemoptysis, bleeding comes from the bronchial arteries as opposed to the pulmonary arteries.

| ==Causes==

| This can be due to [[bronchitis]] or [[pneumonia]] most commonly, but also to [[lung cancer|lung neoplasm]] (in smokers, when hemoptysis is persistent), [[aspergilloma]], [[tuberculosis]], [[bronchiectasis]], [[coccidioidomycosis]], [[pulmonary embolism]], or [[Bubonic plague|pneumonic plague]].
| |
|
| |
|
| Rarer causes include [[hereditary hemorrhagic telangiectasia]] (HHT or Rendu-Osler-Weber syndrome), or [[Goodpasture's syndrome]] and [[Wegener's granulomatosis]].In children it is commonly due to a [[foreign body]] in the [[respiratory tract]].
| | ==[[Hemoptysis overview|Overview]]== |
|
| |
|
| It can result from over-anticoagulation from treatment by drugs such as [[warfarin]].
| | ==[[Hemoptysis historical perspective|Historical Perspective]]== |
|
| |
|
| Cardiac causes like congestive heart failure and mitral stenosis should be ruled out.
| | == [[Hemoptysis classification|Classification]] == |
|
| |
|
| The origin of blood can be known by observing its color. Bright red, foamy blood comes from the respiratory tract while dark red, coffee-colored blood comes from the [[gastrointestinal tract]].
