Bronchitis is a lung disease in which bronchial and tracheal secretions increase and can be caused by either infectious or non-infectious factors. Patients who smoke are far more likely to develop bronchitis than those who do not smoke. The classification of bronchitis can be divided into two types: acute and chronic. The main causes of bronchitis are viral and bacterial infections. The triggering factors are dust, PM2.5
Inhalation of toxic gases such as dust, PM2.5, cold air, smoking, etc. Self-imposed causes are generally a decrease in immunity and a dysfunctional whistle. The clinical symptoms of bronchitis are: (1) cough. Acute patients have an acute onset and usually present with a dry cough, while patients with chronic bronchitis have a long and easily recurring cough; (2) coughing sputum; (3) shortness of breath in the whistle can be present, commonly in the acute phase. Early symptoms are mild and usually not obvious. The disease has a long and slowly persistent course. The late stage tends to affect health and lung function. There may be no abnormalities in the early stage of lung auscultation, or only coarse whistling sounds can be heard, and scattered dry and wet rales can be heard as the disease gradually progresses. In life, it is important to take precautions against bronchitis, to quit smoking, to stay away from places with a lot of smoke, to wear a mask when you go out, and to keep the air circulating indoors to prevent colds and keep warm. Do early detection and treatment to prevent the occurrence of the disease.
