What is the reason for blood in sputum

If there is blood in the sputum but there is no cough, it may be caused by dry weather. It is a seasonal disease and will heal after a period of time. If you suffer from chronic pharyngitis, this adverse phenomenon will also occur. The most worrying thing is that the patient has a tumor or tuberculosis and other diseases. At this time, active examination and treatment are necessary.

1. Causes of blood in sputum

1. It may be due to the dry climate, which is related to seasonality.

2. Chronic pharyngitis can also cause this symptom, especially during an attack.

3. Acute and chronic infections of the trachea and bronchi.

4. Rare diseases such as tumors, tuberculosis, bronchiectasis, etc. cannot be ruled out. Bronchiectasis refers to the abnormal, irreversible expansion and deformation of the lumen of proximal medium-sized bronchi due to the destruction of the muscle and elastic components of the bronchi's walls.

2. Inspection

1. Chest X-ray: lung infection, lung cancer or cardiovascular disease, etc.

2. Sputum examination: Y-cell or lung cancer

3. General blood and coagulation

4. It helps in the intuitive or etiological diagnosis of bronchiectasis. Fiberoptic bronchoscopy can detect areas of bleeding, dilation or obstruction, and can also perform local lavage for smear, bacteriological, and cytological examinations. Selective bronchography can also be performed through fiberoptic bronchoscopy. Pulmonary function tests can confirm airflow limitation due to diffuse bronchiectasis or related obstructive lung disease. Sputum examination often shows abundant neutrophils and polymicrobial colonization or infection. Sputum smear staining and sputum bacterial culture results can guide antibiotic treatment. The total white blood cell count and classification are generally within the normal range, and the white blood cell and neutrophil counts increase during acute infection.

3. Prevention and Treatment

Pay attention to protecting your respiratory system at ordinary times, and seek medical diagnosis immediately if any problems occur. Prevention and treatment of acute and chronic respiratory infections such as measles, whooping cough, bronchopneumonia and tuberculosis are of great significance in preventing bronchiectasis. Patients with bronchiectasis should actively prevent respiratory infections, adhere to body position for expectoration, and enhance the body's immune function to improve the body's disease resistance.
