What is the cause of children coughing up blood? Parents must read

Many people think that coughing and spitting up blood is a very serious illness, especially when children cough and spit up blood, parents will be very worried and scared. There is a difference between children coughing up blood and vomiting blood. Coughing up blood may be caused by bronchitis or bronchiectasis.

1. bronchitis. The course of the disease is generally long. Due to long-term inflammation, the bronchial wall mucosa becomes congested. After severe coughing, blood vessels are damaged, causing a small amount of bleeding. When coughing, there are blood streaks in the sputum, and in severe cases, there are small blood clots.

2. Bronchiectasis. It often occurs after whooping cough or chronic bronchitis, causing the trachea walls to deform and dilate. It may manifest as repeated coughing, especially in the early morning when coughing up large amounts of purulent sputum, sometimes with blood in the sputum. If necessary, bronchoscopy or iodized oil angiography can be performed to confirm the diagnosis.

3. tuberculosis. The children suffer from long-term low fever, cough, fatigue, weight loss, and sweating. The sputum coughed up may contain blood, which usually indicates a history of contact with tuberculosis. A chest X-ray can provide a clear diagnosis.

4. Systemic bleeding disorders. It may be caused by thrombocytopenia, capillary defects or coagulation factor deficiency. In addition to coughing up blood, there may also be bleeding in other parts of the body.
