The etiology of chronic bronchitis is not very clear at present. It is considered that many factors work over a long period to cause chronic bronchitis. The most common factors include long-term irritation from harmful gases and particles, such as cigarette smoke, smog, dust, irritating gases like sulfur dioxide, nitrogen dioxide, etc., as well as infectious factors. There might also be a certain relationship with the occurrence of chronic bronchitis, but so far, no close relationship has been found between chronic bronchitis and genetics, and there is no evidence to prove that chronic bronchitis is a hereditary disease.

How to treat chronic bronchitis?

Chronic bronchitis is divided into acute exacerbation phase and remission phase. The treatment during acute exacerbation mainly focuses on controlling infections, and administrating antitussive, expectorant, and asthma-relieving medications. To control infections, antibiotics are empirically selected based on the common pathogens in the area. If the pathogen can be cultured, an antibiotic sensitive to the organism can be chosen based on the test. Oral administration is generally sufficient. In severe cases, medication can be administered intravenously. Patients with asthma are given bronchodilators. During the remission phase, treatment involves quitting smoking, avoiding inhalation of harmful gases and other harmful particles, strengthening physical health, preventing colds, and for patients with repeated respiratory infections, vaccines or immunomodulators may be administered to enhance immunity.

Can chronic bronchitis be treated?

Chronic bronchitis, commonly known as "chronic obstructive bronchitis," is treatable. The primary symptoms of chronic bronchitis are coughing and expectoration. If the disease occurs for more than three months each year, for two consecutive years, while excluding other organic diseases, chronic bronchitis can be diagnosed. Treatment for chronic bronchitis is divided into two parts. During acute exacerbations, which typically present with worsened coughing and expectoration, increased sputum volume, or the presence of purulent sputum and possibly accompanied by wheezing and fever, the main treatment is anti-infection. The primary medications for anti-infection are antimicrobial drugs, which include macrolides, quinolones, cephalosporins, etc. Additionally, treatment can be aimed at alleviating symptoms of coughing and expectoration and might include expectorants and cough suppressants, such as ambroxol. For wheezing, medications like aminophylline or nebulized treatments may be necessary. Most of the time, patients with chronic bronchitis are in a remission phase. The primary treatment here initially involves addressing known triggers, such as insisting smokers quit and minimizing exposure to dust or harmful gases at work. Chronic bronchitis patients are encouraged to exercise moderately, strengthen their physique, and prevent colds. For patients who experience repeated respiratory infections, vaccination or immune modulators, such as BCG, may be considered. Always follow a physician’s guidance regarding specific medication use.

How to cure chronic bronchitis completely?

At present, there is no cure for chronic bronchitis, and most treatments are mainly aimed at alleviating its symptoms. The treatment is mainly divided into two parts, one is the treatment during the acute exacerbation phase, which means that if a patient with chronic bronchitis experiences acute worsening of symptoms such as coughing and expectoration, or if accompanied by wheezing, fever, etc., then the main treatment methods might include anti-infection measures, expectorants to relieve cough, or treatments to alleviate wheezing. Most patients with chronic bronchitis are likely in the remission phase most of the time, and the primary treatment during this phase is initially to address factors that might trigger chronic bronchitis, such as insisting that patients who smoke quit smoking, and for those who have been exposed to dust or smoke, it is crucial to resolve triggering factors and avoid contact with harmful gases or inhalation of harmful particles. The next step is to enhance physical fitness and prevent colds. Chronic bronchitis patients can engage in appropriate physical exercise based on their condition, and those who suffer from long-term recurrent infections might consider pursuing immunotherapy.

What are the symptoms of chronic bronchitis?

Chronic bronchitis is also colloquially known as "old chronic bronchitis." From this name, we can tell that patients usually develop the disease slowly with a long duration, lasting for years, even decades. The symptoms, such as coughing and expectoration, can acutely worsen repeatedly. Most patients cough and produce phlegm mostly when indoors, particularly noticeable upon waking in the morning and also possibly at night. The phlegm is typically white, sticky, or serous and foamy; occasionally, it may be blood-streaked. During acute exacerbations of chronic bronchitis or when accompanied by an infection, pus-like yellow phlegm or green bloody sputum may appear. Additionally, a small number of patients may experience wheezing, also known as asthmatic bronchitis.

Chronic bronchitis symptoms

Chronic bronchitis is also known as "old chronic bronchitis." From the name, it can be inferred that its cough and expectoration last for a long time and its onset is slow, which can manifest as acute exacerbation. The main symptoms of chronic bronchitis are cough and expectoration, either with or without wheezing. The cough in chronic bronchitis usually occurs in the morning, meaning that the cough is more pronounced upon waking up. The sputum is generally white, sticky, mucoid, or frothy, and may occasionally contain streaks of blood but generally is not associated with coughing up blood. In addition to coughing and expectoration, a small number of patients may experience wheezing or shortness of breath. In cases where the wheezing is more pronounced, it is also referred to as asthmatic bronchitis.
