Definition

Noun: * The act of coughing up blood or blood-stained mucus from the respiratory tract (the bronchi, trachea, or lungs). This is typically a symptom of a serious underlying condition, such as a severe infection, tuberculosis, or cancer.

Usage

• Medical Symptom: "Hemoptysis" is a clinical term used by healthcare professionals to describe a specific symptom. It is important for patients to report any instance of hemoptysis to a doctor immediately.
• Distinction from Hematemesis: It is crucial to distinguish hemoptysis (coughing up blood from the lungs) from hematemesis (vomiting up blood from the gastrointestinal tract), as they indicate problems in different organ systems.

Examples

• The patient was admitted to the emergency room due to hemoptysis and shortness of breath.
• Persistent hemoptysis can be a sign of pulmonary tuberculosis.
• The doctor asked if the blood was coughed up (hemoptysis) or vomited (hematemesis).

Advanced Usage

• Massive Hemoptysis: A medical emergency defined as coughing up a large volume of blood (e.g., more than 100-600 mL in 24 hours, depending on the definition), which can be life-threatening due to airway obstruction or blood loss.
• Pseudohemoptysis: This refers to coughing up blood that originates from a source other than the lower respiratory tract, such as the nose, mouth, or throat (e.g., from a nosebleed).

Variants and Related Words

• Hemoptysic (adjective): Relating to or characterized by hemoptysis. (e.g., )
• Hematemesis (noun): The vomiting of blood. This is a different condition from hemoptysis.
• Expectoration (noun): The act of coughing up and spitting out material from the lungs. Hemoptysis is a type of expectoration involving blood.

Synonyms

• Coughing up blood
• Bloody sputum (though this specifically refers to the mucus mixed with blood)

Antonyms

• There is no direct antonym, but the absence of the symptom would be described as "no hemoptysis" or "absence of hemoptysis."

Notes

• "Hemoptysis" is derived from Greek roots: (blood) and (spitting).
• It is a formal medical term. In non-medical conversation, people would typically say "coughing up blood."
