Symptoms of bronchitis?
summary
The main cause of bronchitis is chronic nonspecific inflammation of bronchus caused by repeated infection of virus and bacteria. When the temperature drops, the small vasospasm and ischemia of respiratory tract, and the defense function decreases, it is beneficial to cause the disease; Chronic irritation such as smog, dust and air pollution can also cause the disease; Smoking can cause bronchospasm, mucosal variation, decreased ciliary movement and increased mucus secretion, which is beneficial to infection; Allergic factors also have a certain relationship. Symptoms of bronchitis? I'd like to share my views with you.
Symptoms of bronchitis?
Acute bronchitis the early stage of acute bronchitis is often manifested as upper respiratory tract infection symptoms, patients usually have nasal congestion, runny nose, sore throat and hoarseness and other clinical manifestations. The general symptoms are mild, but there may be low fever, chills, fatigue, conscious throat itching, irritating cough and retrosternal pain. In the early stage, the amount of sputum was not much, but the sputum was not easy to cough up. 2-3 days later, the sputum could change from mucinous to mucopurulent. Cold, inhaling cold air or irritant gas can aggravate or induce cough. The cough is often obvious in the morning or at night. Cough can also be paroxysmal, sometimes persistent cough. Severe cough is often accompanied by nausea, vomiting and chest, abdominal muscle pain. If accompanied by bronchospasm, there may be wheezing and shortness of breath. Generally speaking, the course of acute bronchitis has a certain self limitation. The general symptoms can subside in 4-5 days, but sometimes cough can be prolonged for several weeks. Sometimes dry rales can be found on physical examination and disappear after coughing; Moist rales can occasionally be heard at the bottom of the lung, and wheezing can be heard when accompanied by bronchospasm. Usually, the white blood cell count is normal, and there is no abnormality in chest X-ray examination.
Chronic bronchitis chronic bronchitis refers to patients with chronic cough and expectoration for more than three months every year for two consecutive years, excluding various other causes of chronic cough. It is not necessarily accompanied by persistent airflow limitation. (1) long term, repeated and gradually aggravating cough is the prominent manifestation of the disease. Mild cases only occur in winter and spring, especially before and after getting up in the morning. Cough is less in the daytime. In summer and autumn, cough is relieved or disappeared. Severe patients cough in all seasons, especially in winter and spring, day and night. (2) expectoration of sputum is usually white mucous and foam, which is more frequent in the morning. After infection or cold, the symptoms quickly worsened, the amount of sputum increased, viscosity increased, or yellow purulent sputum or accompanied by wheezing. Occasionally, the sputum is bloody due to severe cough. (3) wheezing when complicated with respiratory tract infection, due to congestion and edema of bronchiolar mucosa, obstruction of sputum and stenosis of bronchial lumen, asthma (wheezing) symptoms may occur. Wheezing occurred in the throat during breathing and wheezing occurred in the lung during auscultation. (4) repeated infection in cold season or sudden change of temperature is prone to recurrent respiratory tract infection. At this time, the patient's asthma aggravated, the amount of sputum increased significantly and was purulent, accompanied by general fatigue, chills, fever and so on. Wet sound appeared in the lung, and the white blood cell count increased. Repeated respiratory tract infection is especially easy to worsen the condition of elderly patients, we must pay full attention to it.
Diet should be light, avoid spicy meat. Should quit smoking and drink more tea, because smoking will cause respiratory secretions increase, reflex bronchospasm, sputum difficult, conducive to the growth and reproduction of viruses and bacteria, make chronic bronchitis further worse. Tea contains theophylline, can excite sympathetic nerve, make bronchiectasis and reduce cough and asthma symptoms.
