Pulmonary Haemorrhage

Pulmonary haemorrhage is a medical condition that affects the lungs and respiratory system. Sudden, severe bleeding in the lungs can cause serious health issues, including coughing up blood and chest pain. It can be caused by several factors, including injuries or underlying medical conditions. Prompt diagnosis and treatment are essential to avoid potentially life-threatening complications. Early detection of pulmonary haemorrhage is key to the successful management of this condition.

What is pulmonary haemorrhage?

Pulmonary haemorrhage (or haemoptysis) is the coughing up of blood from the respiratory tract, usually originating in the lungs. It is sometimes referred to as 'expectoration of blood' or 'hemoptysis'. It can be caused by a variety of conditions, such as pulmonary embolism, pneumonia, tuberculosis, bronchiectasis, lung cancer, and pulmonary infarction. In some cases, it may also be due to a condition that affects the entire body, such as a bleeding disorder or even systemic lupus erythematosus. Treatment for pulmonary haemorrhage depends on the underlying cause and may involve medications, surgical procedures, lifestyle changes, or other therapies.

What are the different types of pulmonary haemorrhage?

There are various types of pulmonary haemorrhage. The main type is "primary" pulmonary haemorrhage, which occurs due to a disorder or disease of the lungs themselves, such as lung cancer, pneumonia, or blockage of small airways. Another type is "secondary" pulmonary haemorrhage, which is caused by diseases in other areas of the body that affect the lungs, such as pulmonary hypertension and heart disease. A third type is "idiopathic", which means it has an unknown cause. Finally, a fourth type is known as "hemoptysis", where a person coughs up blood from the lungs.

What are the causes of pulmonary haemorrhage?

Pulmonary haemorrhage is commonly caused by high blood pressure in the lungs, which can be due to a variety of underlying conditions. These include cystic fibrosis, pulmonary embolism, vasculitis, and diseases that damage the pulmonary arteries or capillaries. It can also result from high doses of chemotherapy or radiation therapy, prolonged ventilator use, and some infections, such as Pneumocystis pneumonia. In addition, it may be an inherited disorder or a side effect of certain medications.

What are the symptoms of pulmonary haemorrhage?

A pulmonary haemorrhage is characterised by coughing up blood. In some cases, a person may not be aware of the bleeding, as it can manifest as dark-coloured sputum or phlegm. Other symptoms include shortness of breath, chest pain, lightheadedness, and palpitations. Hoarseness and fatigue can also occur in some cases, as well as fever, a rapid heart rate, and a bluish tint to the skin due to a lack of oxygen. Blood tests may be used to confirm pulmonary haemorrhage in addition to imaging techniques such as X-rays and CT scans.

When should you see a doctor for pulmonary haemorrhage?

If you experience any symptoms of pulmonary hemorrhage, such as coughing up blood or shortness of breath, you should seek medical attention immediately. If left untreated, this condition can be life-threatening and require urgent medical intervention. It is also important to see a doctor if the coughing persists for more than two weeks or if you find yourself getting out of breath after minimal exertion. Respiratory failure may result from severe bleeding in the lungs, so it is essential to seek medical advice at the earliest possible opportunity.


Pulmonary haemorrhage is a serious condition that can be life-threatening if not treated quickly. Early detection and prompt medical intervention can prevent further complications and improve outcomes. In conclusion, pulmonary haemorrhage is a potentially dangerous condition that requires immediate medical attention to ensure the best possible outcome. With proper medical care and supervision, it is possible to mitigate the risks associated with this condition and ensure a successful recovery.
