What happened to the sudden coughing up of blood? The reason turned out to be this

Sudden coughing up blood is a symptom that makes people very scared, because people don’t know what causes the coughing up blood. Many people even think they have an incurable disease. In fact, there are many reasons that can cause the human body to suddenly cough up blood. Let’s take a closer look!

Hemoptysis refers to the symptom that blood comes from the lungs or trachea and comes out with coughing. It is mostly caused by trauma, or external evil invading the lungs, liver fire invading the lungs, yin deficiency and hyperactivity of fire, or qi failing to restrain blood, which damages the lung meridian and causes blood to overflow from the vessels. Various lung diseases such as tuberculosis, lung cancer, pulmonary collateral dysentery, as well as hemorrhage, erythrocyte sedimentation, rice blast, heart failure, etc. can all cause coughing up blood.

1. First, we should rule out bleeding from the nose, pharynx, and mouth, as well as vomiting blood (which comes from the upper digestive tract, often contains food residues, the blood is acidic, and is often accompanied by black stools), and confirm that it is hemoptysis (the blood comes out with coughing, often contains bubbles and sputum, and the blood is alkaline).

2. Generally, a chest X-ray examination should be performed . If necessary, fiberoptic examination, bronchial iodized oil contrast, electrocardiogram and other examinations can be performed to help determine and differentiate the diagnosis.

3. Conduct diagnostic thinking based on the condition , such as:

(1) Repeated coughing for many years, or coughing up blood, is usually caused by pulmonary edema or tuberculosis.

(2) Coughing up blood accompanied by purulent sputum is usually caused by lung heat disease, lung abscess, lung collateral enlargement, etc.

(3) Continuous coughing up of small amounts of blood or blood in sputum, especially in men over 40 years old and long-term smokers, should be alert to lung cancer.

(4) For those with a history and signs of heart disease, coughing up blood may be related to the disease.

(5) Acute onset with high fever and coughing up blood is usually caused by febrile diseases such as pulmonary fever, pulmonary ecdysis, and rice blast.

(6) If coughing up blood is difficult to control and is accompanied by other systemic bleeding, the possibility of systemic bleeding disease, such as hemorrhage and myelopathy, should be considered.

(7) Whooping cough is a paroxysmal cough that can occasionally cause coughing up blood when the cough is severe.

(8) Women who experience periodic nosebleeds or coughing up blood during menstruation are called menstrual vomiting and bleeding.

(9) Traumatic damage to the lung network causes hemoptysis, with an obvious history of trauma.

4. Common symptoms are as follows:
