Coughing up blood, also known as hemoptysis, can be a sign of a serious medical condition and should be checked out by a doctor as soon as possible. The most common reason for coughing up blood is a chest infection, such as pneumonia. Other common causes include:
- Pneumonia: An inflammation of the lung tissue often caused by a bacterial or viral infection.
- Chronic Obstructive Pulmonary Disease (COPD): A group of lung diseases that block airflow and make it difficult to breathe.
- Cystic Fibrosis: A genetic disorder that affects the lungs and digestive system.
- Lung Cancer: A serious disease where abnormal cells grow in the lungs.
- Mitral Valve Stenosis: A condition where the mitral valve in the heart doesn't open fully, causing blood to back up in the lungs.
In some cases, no cause is found for coughing up blood.
If you are coughing up blood, you may cough up:
- Blood-streaked sputum: This is when there is a small amount of blood mixed in with phlegm.
- Bright red blood: This indicates a more serious condition.
Important Note: Coughing up blood can be a symptom of a serious medical condition. If you are experiencing this symptom, it is important to see a doctor right away.
