The treatment of chronic bronchitis is generally symptomatic treatment and most acute bronchitis such as relieving cough, resolving phlegm and relieving asthma. Patients do not need antibiotics unless there is a definite bacterial infection. Both biological and abiotic factors can lead to bronchitis. Among them, virus infection is one of the most common causes, and a few patients may have bacterial infection. Biological factors such as age and immunity may affect the onset or acute exacerbation of bronchitis, and mycoplasma or chlamydia infection may lead to a temporary attack of bronchitis. Abiotic factors, including seasonal changes, irritating gases or particles of cold air and dust, smoke inhalation, etc., can all lead to bronchial mucosal injury and inflammatory reaction. Bronchitis, pay attention to prevent colds, avoid smoking, and avoid inhaling cold air, dust and pollen. And pay attention to more exercise to enhance physical fitness. First, patients with bronchitis should pay attention to colds at ordinary times, because colds can easily induce bronchitis, or lead to severe bronchitis. Inflammation on food and bronchial mucosa is mainly caused by pathogen infection. When patients catch a cold, pathogens in the body will multiply in large numbers. Leading to the aggravation of bronchitis. Second, patients with bronchitis should avoid smoking, because smoking may cause damage to bronchial mucosa and aggravate inflammation. Inhaling cold air, dust and pollen can easily stimulate the trachea, causing tracheal allergy, which in turn leads to aggravation of inflammation and bronchitis. Usually, we should pay more attention to physical exercise, enhance physical fitness, improve disease resistance and promote the recovery of bronchitis. For example, you can usually do more, do aerobic exercise, and exercise for more than half an hour every day. We can supplement more vitamins and increase nutrition in our diet. Bronchitis may aggravate cough and affect lung function, and it is also prone to complications and bronchitis. Usually refers to bronchial inflammation caused by various treatments, which can be acute bronchitis, chronic bronchitis and chronic bronchitis. If not treated in time, or if the condition is serious, it will usually cause serious harm to the human body. It may cause congestion and swelling of bronchial mucosa, decreased function of fibrous columnar epithelium, proliferation of goblet cells, resulting in increased secretion, and patients repeatedly cough and expectorate, because the ciliated columnar epithelium is not specific to prevent it from decreasing. It is impossible to expel the virus and bacteria in the inhaled air with sputum in time, so it may further aggravate bronchitis. Second, it may affect lung function, because after the patient has bronchitis, bronchopulmonary spasm leads to limited expiratory flow rate, and the gas in the lung stays in the lung for a long time, which will lead to excessive expansion of alveoli. When the alveoli expand to a certain extent, it will lead to the rupture of alveolar elastic fibers, which will lead to emphysema and emphysema, further aggravating respiratory function. When it reaches a certain level, it may also lead to chronic pulmonary hypertension, chronic pulmonary heart disease and other diseases. Third, the process of patients' complications, basic diseases, diabetes, hypertension, coronary heart disease and cardiac insufficiency. Due to the long course of disease, the use of various drugs can induce various complications, such as chronic pulmonary heart disease. , may further aggravate the original basic diseases, other diseases, damage, acute bronchitis attack and repeated medication will be aggravated, liver and kidney function will be damaged to varying degrees, which may endanger the lives of patients. In daily life, patients are advised to have regular physical examinations to understand their recent physical condition. If there is any abnormality, try to find it as early as possible and treat it as early as possible. In addition, if patients feel unwell, they should seek medical advice in time to avoid delaying their illness. It is recommended that patients increase appropriately. Running and mountain climbing help to improve the body's resistance.
