Pneumonia mainly refers to the inflammation of lung parenchyma, which is a common respiratory disease. Most of them are caused by microorganism, physical and chemical stimulation, allergic reaction and so on. Every season, people will get sick, but mainly in winter and spring.

What are the early symptoms of pneumonia in middle-aged people?

The most common infectious pneumonia is fever, weakness, discomfort and other systemic symptoms, as well as cough, expectoration, chest pain, shortness of breath and other local symptoms. Pneumonia is inflammation of the lung parenchyma. Lung parenchyma is the part of the lung for gas exchange, which mainly refers to the terminal respiratory unit mainly composed of alveoli. Inflammation may spread to the whole lung or concentrate in limited areas.

  most cases of pneumonia have acute onset and short course of disease, and those with course less than one month are acute pneumonia; The course of disease in 1 ~ 3 months is called persistent pneumonia; More than 3 months of chronic pneumonia. According to the way of infection, infectious pneumonia can be divided into aspiration pneumonia (including inhalation of infectious particles in the air, oropharyngeal secretions and gastric juice, etc.), hematogenous disseminated pneumonia and traumatic pneumonia (infection caused by chest penetrating injury, trauma caused by diagnostic or therapeutic operation of the lung, etc.). Pneumonia can be divided into primary pneumonia and secondary pneumonia.

If inflammation first occurs in the lung tissue, it is called primary pneumonia, which is mainly caused by pathogenic factors entering the lung through the airway. Secondary pneumonia generally refers to all pulmonary inflammatory complications in the case of systemic or pulmonary diseases, which may be caused by the spread of microorganisms in the original lesions outside the lung into the lung, while the original diseases cause the decline of systemic or pulmonary resistance, and the secondary pneumonia caused by the invasion of resident bacteria in the body into the lung tissue is more common.
