Why does coughing cough and bleed?

Because when coughing or stimulating the tracheal wall, the blood vessels on the tracheal wall rupture and bleed. The more you cough, the more you bleed! ! There are many reasons for blood in sputum. Common ones are; (1) Bronchial diseases, such as bronchiectasis, chronic bronchitis, bronchial lung cancer, etc. (2) Lung diseases, such as tuberculosis and pneumonia. (3) Cardiovascular diseases, such as pulmonary congestion caused by mitral stenosis. (4) Blood diseases and some acute infectious diseases. There is unknown blood in the sputum of middle-aged and elderly people, especially a stabbing cough, which is often a precursor to bronchial lung cancer. There are abundant blood channels in cancer tissue. Irritating cough caused by cancer often leads to capillary rupture and blood in the disease, which is characterized by intermittent repetition, a small amount of blood sputum, and blood is often more than sputum. Tumors, such as blood vessels with large infiltration, often have massive hemoptysis after rupture. Hemoptysis is the phenomenon that blood comes out of the lung and coughs up through the airway due to lung collateral injury, or pure blood is bright red, or blood is in sputum, or blood is in sputum. Also known as cough and hemoptysis. Exogenous pathogens attacking the lung, phlegm and blood stasis blocking the lung, liver fire invading the lung, yin deficiency of the lung and kidney, and qi deficiency that cannot be absorbed all cause lung collateral damage, lung qi ascending and descending, and blood overflowing the airway. Generally, exogenous hemoptysis has a short course of disease and an acute onset. At the beginning, there were symptoms such as fever and aversion to cold. The onset of hemoptysis due to internal injury is slow, and the course of disease is long, all of which are manifested as deficiency or excess of Qi and blood of viscera, yin and yang. To treat hemoptysis caused by excess fire, we should clear away heat and purge fire, cool blood and stop bleeding, and choose Allium Macrostemon Powder combined with Daige Powder, Qingzao Jiufei Decoction and Qianjin Weijing Decoction. For hemoptysis due to deficiency fire, it is advisable to nourish yin and clear heat, smooth collaterals and stop bleeding, and choose Lily Gujin Decoction and Yuehua Pill. It is advisable to expel wind and dispel cold, smooth collaterals and stop bleeding, and Jin Fei grass powder should be used for addition and subtraction; Qi deficiency does not cause hemoptysis, so it is advisable to replenish qi, enrich blood and stop bleeding, and use the decoction of saving yang and relieving fatigue to add and subtract. It is easy to accumulate blood and form blood stasis after menstruation, so it is advisable to add drugs for promoting blood circulation and removing blood stasis at the same time to stop bleeding without leaving blood stasis. At the same time, we should strengthen nursing, instruct patients to avoid alcohol and tobacco, keep warm and cold, flirt, don't be tired, and don't eat spicy and phlegm-producing hot things. Modern medicine believes that hemoptysis is a disease in which the bleeding of respiratory organs below the throat is discharged through the mouth. Also called hemoptysis. Hemoptysis should be distinguished from nasal, pharyngeal and oral bleeding and upper gastrointestinal bleeding (hematemesis). The common causes are tuberculosis, bronchogenic carcinoma, bronchiectasis, lung abscess, pneumonia, chronic bronchitis, paragonimiasis, mitral stenosis and some blood diseases (such as thrombocytopenic purpura, leukemia and hemophilia). Its treatment measures include treatment of primary disease and symptomatic treatment. People with blood in sputum or a small amount of hemoptysis can use antitussive, sedative and hemostatic drugs. Patients with moderate or massive hemoptysis should stay in bed strictly, use powerful hemostatic drugs (such as pituitrin), and stop bleeding through fiberoptic bronchoscope and emergency surgery when necessary.
