Suddenly coughing up a lot of bright red blood

Bleeding from any part of the human body is an abnormal phenomenon. However, if you suddenly cough up blood during the coughing process, you must go to the hospital in time to check what disease caused it, because suddenly coughing up a large amount of bright red blood can not only cause a person to go into shock, but may also be caused by a particularly serious disease. The following article will introduce to you the causes of sudden and large amounts of bleeding.

Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis that can invade many organs, with pulmonary tuberculosis infection being the most common. People who excrete bacteria are an important source of infection. A person does not necessarily develop tuberculosis after being infected with tuberculosis bacteria. Clinical illness may only occur when the body's resistance is reduced or cell-mediated allergic reactions increase. If diagnosed promptly and treated appropriately, most patients can recover clinically.

Causes

Mycobacterium tuberculosis belongs to the genus Mycobacterium in the family Mycobacterium, order Actinomycetales, and is a pathogenic, acid-resistant bacterium. It is mainly divided into human, cow, bird, mouse and other types. Those that are pathogenic to humans are mainly human-type bacteria, while bovine-type bacteria rarely cause infection. The drug resistance of tuberculosis bacteria can be formed by the development of innate drug-resistant bacteria in the bacterial flora, or it can be caused by the rapid development of resistance to the drug when a single anti-tuberculosis drug is used in the human body, that is, the acquisition of drug-resistant bacteria. Drug-resistant bacteria can cause difficulties in treatment and affect the efficacy of treatment.

prevention

1. Control the source of infection and detect and treat it in time.

2. Cut off the transmission route by opening windows for ventilation and paying attention to disinfection. 3. Protect susceptible people by vaccinating them with BCG, and take precautions to exercise and improve their own immunity.

Differential Diagnosis

1. The primary syndrome should be differentiated from lymphoma, intrathoracic sarcoidosis, central lung cancer and metastatic cancer.

2. Acute hematogenously disseminated pulmonary tuberculosis should be differentiated from typhoid fever, meningitis, sepsis, pneumoconiosis, alveolar cell carcinoma, and hemosiderosis.

3. Infiltrative pulmonary tuberculosis should be differentiated from various types of pneumonia, lung abscess, pulmonary fungal disease, lung cancer, lung metastasis, lung cysts and other benign lung lesions.
