Understanding Chronic Bronchitis: Causes, Diagnosis, and Treatment
Overview
Chronic bronchitis, often referred to as "chronic bronchitis" or "slow bronchitis," is a chronic non-specific inflammation of the trachea, bronchial mucosa, and surrounding tissues. While the exact causes of chronic bronchitis are not entirely clear, it is likely a result of long-term interaction between multiple factors and individual predispositions. This article will delve into the diagnosis, treatment, and prevention of chronic bronchitis, offering valuable insights for those affected by this condition.
Causes and Symptoms
Chronic bronchitis is primarily caused by exposure to irritants such as smoking, dust, smoke, chemicals, industrial emissions, indoor air pollution, and harmful gases like sulfur dioxide, nitrogen dioxide, and chlorine. Infections with viruses, bacteria, and mycoplasma, immune dysfunction, age, allergic reactions, and climatic factors also contribute to the development of the condition.
Symptoms of chronic bronchitis include a chronic cough, sputum production, wheezing, or shortness of breath. In the early stages, patients may not exhibit any abnormal physical signs. During acute exacerbations, dry or wet rales may be heard in the back or at the base of the lungs. Simple chronic bronchitis may present with mild cough and sputum production, with no significant emphysema or shortness of breath. In contrast, obstructive chronic bronchitis often presents with symptoms of emphysema, and the patient may exhibit prolonged expiration, shortness of breath, or cyanosis.
Diagnosis
Diagnosis is based on a patient's cough, sputum production, or wheezing, with symptoms persisting for at least 3 months each year for 2 consecutive years, excluding other chronic diseases with similar symptoms. X-ray imaging may show increased and disorganized pulmonary markings in patients with recurrent episodes. Pulmonary function tests, such as the ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) (FEV1/FVC) < 0.70 after bronchodilator use, may indicate the development of chronic obstructive pulmonary disease. Blood tests and sputum cultures may also be helpful in diagnosing bacterial infections.
Treatment
Acute Exacerbation
During acute exacerbations, treatment involves anti-infection and cough suppressants. Commonly prescribed antibiotics include levofloxacin, roxithromycin, amoxicillin, cefuroxime axetil, and sulfamethoxazole-trimethoprim. Cough suppressants and expectorants may include guaifenesin, ambroxol, and glycyrrhizin. Patients with asthma may benefit from theophylline, theophylline controlled-release preparations, or β2-agonists.
Remission Period
During the remission period, the focus is on smoking cessation, avoiding exposure to harmful gases and particles, enhancing physical fitness, preventing colds, and getting vaccinated against influenza and pneumonia. Other measures include using "Three Heat Stickers" treatment, ensuring adequate nutrition and hydration, maintaining a comfortable room temperature of 18-20°C, and a relative humidity of 50-60%.
Chinese Medicine Treatment
Chinese herbal medicine can be used for chronic bronchitis, with various formulas tailored to different symptoms. For example, Erchen Decoction may be used for patients with excessive sputum, while Qingzao Jifu Decoction is suitable for dry cough and difficulty expectorating. Other herbal formulas may be prescribed for patients with concurrent infections or obstructive symptoms.
Diet and Other Treatments
Adequate caloric intake and a balanced diet rich in vitamins and minerals are essential. Specific dietary recommendations may include soup and porridge recipes with beneficial herbs and foods. Other treatments may include oxygen therapy, sputum clearance techniques, deep breathing exercises, relaxation techniques, and traditional Chinese therapies like massage, cupping, and acupuncture.
Prevention
Prevention of chronic bronchitis involves strengthening physical fitness, improving resistance to colds, maintaining good personal hygiene, avoiding smoking and alcohol, and a healthy diet. Regular removal of chronic infection foci, such as dental caries, sinusitis, and tonsillitis, is also recommended.
In conclusion, chronic bronchitis is a chronic respiratory condition that requires proper management and treatment. Early diagnosis, adherence to treatment, and lifestyle modifications can significantly improve the quality of life for patients with chronic bronchitis.
