Coughing Up Blood: What are the Causes and When to Seek Care

Introduction

Hemoptysis refers to the medical condition characterized by the coughing up of blood from the respiratory tract, particularly originating from the lungs. Depending on the identified aetiology and severity of bleeding, treatment options may vary. You can seek observation and conservative management for mild cases to more aggressive interventions such as surgical resection or chemotherapy for malignancies. In any case, it is crucial for healthcare professionals to promptly evaluate and manage patients presenting with hemoptysis due to its potential association with life-threatening conditions.

Causes of coughing blood

Hemoptysis, while alarming, can stem from a wide array of underlying conditions ranging from benign to life-threatening. Some of the causes of coughing blood are as follows:

1. Respiratory Infections

Respiratory infections, such as bronchitis, pneumonia, and tuberculosis, can lead to the presence of blood in sputum. These infections cause inflammation and damage to the respiratory tract, which may result in the rupture of blood vessels within the airway walls. The presence of blood-associated symptoms, such as coughing up blood, should warrant immediate medical attention to rule out any severe infections.

2. Pulmonary Embolism

Pulmonary embolism, a condition where a blood clot obstructs blood flow to the lungs, can also cause hemoptysis. When clots dislodge from deep veins in the body (usually the legs) and travel to the lungs, they can damage lung tissue, leading to bleeding. Prompt diagnosis and treatment are essential in preventing complications associated with pulmonary embolism and ensuring patient recovery.

3. Lung Cancer

Lung cancer is one of the most worrying reasons for blood coughing. As tumours grow in the lungs, they infiltrate adjacent blood vessels, producing bleeding and, eventually, hemoptysis. It is important to highlight that the presence of blood in the sputum does not necessarily imply lung cancer. But it should never be dismissed as a potential symptom and should be investigated further.

4. Chronic Lung Conditions

Hemoptysis can be caused by chronic lung disorders such as chronic obstructive pulmonary disease (COPD) or bronchiectasis. These disorders lead to the degeneration and weakening of lung tissue, making blood vessels more prone to rupture. Active care of these disorders, such as regular monitoring and therapy, can significantly minimize the risk of hemoptysis.

5. Trauma or Injury

Trauma or injury to the chest or lungs can cause blood to be present in the sputum. Blunt force or penetrating trauma can result in damage to blood vessels, leading to bleeding. It is vital to consider any recent accidents or injuries when assessing the causes of hemoptysis.

6. Other Causes

While respiratory infections, pulmonary embolism, lung cancer, chronic lung conditions, and trauma account for the majority of hemoptysis cases, there are several other potential causes. These include bleeding disorders, such as haemophilia or von Willebrand disease, certain autoimmune disorders, and iatrogenic causes due to medical interventions. A thorough evaluation by a medical professional is crucial to accurately determine the underlying cause.

Symptoms of coughing blood

Some common symptoms of coughing blood are listed below:

1. Cough

Persistent or recurrent coughing, especially when accompanied by blood, is a prominent symptom associated with hemoptysis. The cough may sometimes be productive, bringing up phlegm or sputum stained with blood.

2. Chest Pain

Hemoptysis can be accompanied by various degrees of chest pain. The pain may be localized, sharp, or dull and may worsen with deep breathing or coughing.

3. Shortness of Breath

Dyspnea or shortness of breath is another common symptom associated with hemoptysis. This may occur due to the underlying pulmonary conditions causing the bleeding, such as infections or tumours.

4. Fatigue and Weakness

In cases where hemoptysis is persistent or severe, individuals may experience fatigue and weakness due to blood loss. Anaemia caused by chronic bleeding may also contribute to these symptoms.

When to seek medical attention?

Determining when to seek medical attention for coughing up blood depends on various factors, such as the amount of blood, the presence of other symptoms, and individual risk factors.

Recognizing the Severity of Hemoptysis

The first step in determining when to seek medical attention for hemoptysis is to assess the amount and persistence of the blood in the cough. If a small amount of blood is expelled, it is likely not an immediate cause for concern. However, if the blood is excessive, recurrent, or accompanied by other severe symptoms, it is crucial to seek medical attention promptly.

Determining When to Seek Medical Attention

While the severity and quantity of the blood expelled during hemoptysis are important considerations, several additional symptoms warrant immediate medical attention. These include:

• Respiratory Distress

If coughing blood is accompanied by difficulty breathing, rapid or shallow breathing, chest pain, or cyanosis (bluish skin discolouration), immediate medical help should be sought, as these symptoms may be indicative of a potentially life-threatening condition.

• Recurrent Hemoptysis

If coughing up blood is recurring or persistent, regardless of the amount, it is essential to contact a healthcare professional promptly. Recurrent hemoptysis may be a sign of an underlying condition that requires proper diagnosis and management.

• Systemic Symptoms

If coughing blood is accompanied by fever, unintentional weight loss, weakness, fatigue, night sweats, or a persistent cough lasting more than three weeks, it is vital to seek medical attention. These systemic symptoms may suggest an underlying illness that needs medical investigation.

• Risk Factors

Individuals with a history of lung cancer, smoking, exposure to environmental toxins, or a family history of hereditary lung conditions need to be particularly cautious. They should be vigilant in seeking immediate medical attention if they experience hemoptysis, regardless of the amount.
