What is the reason for blood in saliva? It turns out that you have these diseases

Under normal circumstances, saliva is colorless and odorless. Once blood appears, it is very likely that you have an acute or chronic respiratory disease, such as tuberculosis, pneumonia, lung abscess, chronic bronchitis, bronchiectasis, pulmonary edema, etc.

1. Blood in sputum is often seen in lung or bronchial diseases , or even nasopharyngeal inflammation. Dry weather can also cause blood in sputum. If it happens occasionally, it is not possible to determine what disease you have. If you cough up bloody sputum every day or continuously, and are accompanied by cough, chest pain, fatigue, fever, etc., you should go to the hospital's internal medicine department for diagnosis and treatment.

2. The main causes of hemoptysis are : acute or chronic respiratory inflammation, such as pulmonary tuberculosis, pneumonia, lung abscess, chronic bronchitis, bronchiectasis, pulmonary edema, etc.; cardiovascular diseases, such as mitral valve stenosis due to rheumatic heart disease, etc.; tumors occurring in the trachea, bronchi, lungs, mediastinum, and chest wall; hemorrhagic diseases, such as leukemia, hemophilia, etc.

3. But the most common causes are bronchial disease, tuberculosis and lung cancer. Patients with bronchiectasis and chronic bronchitis often have symptoms of hemoptysis, but most of them are small amounts of hemoptysis or blood in the sputum. Pulmonary tuberculosis may cause hemoptysis symptoms at different stages of its development. Most of the time, it is blood in the sputum or a small amount of hemoptysis. However, when the disease progresses and the lesions dissolve to form cavitary tuberculosis, it can cause rupture of small arteries and cause massive or even fatal hemoptysis. Lung cancer usually presents with blood in sputum or a small amount of hemoptysis. Occasionally, when the tumor spreads and erodes larger blood vessels, especially arteries, fatal massive hemoptysis may occur.

Precautions

Regarding what happens when there is blood in spit, it is also important to note that if an elderly person suffers from hemoptysis at home, family members, friends and the patient himself should not panic, especially the patient should avoid fear and anxiety, because panic can aggravate bleeding and easily cause choking. When coughing up blood, the patient must remain calm and must spit out the blood. Never hold it in, as this will prevent the blood in the trachea or bronchi from being discharged, blocking the trachea and causing suffocation and death. Secondly, you must strictly rest in bed. If the location of the lesion is known, lie on the affected side to prevent blood from flowing into the healthy lung.
