Hemoptysis is the term for coughing up blood or bloody mucus from your respiratory tract (lungs and throat). It’s not the same as bleeding from your mouth, throat or gastrointestinal tract, though it may look similar.
Blood can appear bubbly since it includes air and mucus. It may be bright red, rust-colored or have bloody streaks.
Symptoms and causes are usually treatable. However, hemoptysis can be life-threatening. These conditions or treatments can make you cough up blood:
- Inhaling food, saliva or stomach acid (pulmonary aspiration)
- Procedures such as bronchoscopy (viewing airway and lungs with a lighted tube) and biopsy (taking a sample)
- Bronchiectasis (widens airways)
- Bronchitis (bronchial tube or airway inflammation)
- Diseases such as cancer or cystic fibrosis
- Blood vessel inflammation (vasculitis)
- Lung artery injuries
- Violent coughing
- Lung infections such as pneumonia
- Pulmonary edema (lung swelling)
- Autoimmune diseases such as lupus
- Tuberculosis (bacterial disease)
- Medications
