Chronic Bronchitis

What is chronic bronchitis?

From: MedlinePlus, National Library of Medicine

Chronic bronchitis is a type of COPD (chronic obstructive pulmonary disease). COPD is a group of lung diseases that make it hard to breathe and get worse over time. The other main type of COPD is emphysema. Most people with COPD have both emphysema and chronic bronchitis, but how severe each type is can be different from person to person.

Chronic bronchitis is inflammation (swelling) and irritation of the bronchial tubes. These tubes are the airways that carry air to and from the air sacs in your lungs. The irritation of the tubes causes mucus to build up. This mucus and the swelling of the tubes make it harder for your lungs to move oxygen in and carbon dioxide out of your body.

What causes chronic bronchitis?

The cause of chronic bronchitis is usually long-term exposure to irritants that damage your lungs and airways. In the United States, cigarette smoke is the main cause. Pipe, cigar, and other types of tobacco smoke can also cause chronic bronchitis, especially if you inhale them.

Exposure to other inhaled irritants can contribute to chronic bronchitis. These include secondhand smoke, air pollution, and chemical fumes or dusts from the environment or workplace.

Rarely, a genetic condition called alpha-1 antitrypsin deficiency can play a role in causing chronic bronchitis.

Who is at risk for chronic bronchitis?

From: MedlinePlus, National Library of Medicine

The risk factors for chronic bronchitis include:

• Smoking. This the main risk factor. Up to 75% of people who have chronic bronchitis smoke or used to smoke.
• Long-term exposure to other lung irritants, such as secondhand smoke, air pollution, and chemical fumes and dusts from the environment or workplace.
• Age. Most people who have chronic bronchitis are at least 40 years old when their symptoms begin.
• Genetics. This includes alpha-1 antitrypsin deficiency, which is a genetic condition. Also, smokers who get chronic bronchitis are more likely to get it if they have a family history of COPD.

What are the symptoms of chronic bronchitis?

From: MedlinePlus, National Library of Medicine

At first, you may have no symptoms or only mild symptoms. As the disease gets worse, your symptoms usually become more severe. They can include:

• Frequent coughing or a cough that produces a lot mucus
• Wheezing
• A whistling or squeaky sound when you breathe
• Shortness of breath, especially with physical activity
• Tightness in your chest

Some people with chronic bronchitis get frequent respiratory infections such as colds and the flu. In severe cases, chronic bronchitis can cause weight loss, weakness in your lower muscles, and swelling in your ankles, feet, or legs.

How is chronic bronchitis diagnosed?

From: MedlinePlus, National Library of Medicine

Your health care provider may use many tools to make a diagnosis:

• A medical history, which includes asking about your symptoms
• A family history
• Various tests, such as lung function tests, a chest x-ray or CT scan, and blood tests

What are the treatments for chronic bronchitis?

From: MedlinePlus, National Library of Medicine

There is no cure for chronic bronchitis. However, treatments can help with symptoms, slow the progress of the disease, and improve your ability to stay active. There are also treatments to prevent or treat complications of the disease. Treatments include:

• Lifestyle changes, such as Quitting smoking if you are a smoker. This is the most important step you can take to treat chronic bronchitis. Avoiding secondhand smoke and places where you might breathe in other lung irritants Ask your health care provider for an eating plan that will meet your nutritional needs. Also ask about how much physical activity you can do. Physical activity can strengthen the muscles that help you breathe and improve your overall wellness.
• Medicines, such as Bronchodilators, which relax the muscles around your airways. This helps open your airways and makes breathing easier. Most bronchodilators are taken through an inhaler. In more severe cases, the inhaler may also contain steroids to reduce inflammation. Vaccines for the flu and pneumococcal pneumonia, since people with chronic bronchitis are at higher risk for serious problems from these diseases. Antibiotics if you get a bacterial or viral lung infection
• Oxygen therapy, if you have severe chronic bronchitis and low levels of oxygen in your blood. Oxygen therapy can help you breathe better. You may need extra oxygen all the time or only at certain times.
• Pulmonary rehabilitation, which is a program that helps improve the well-being of people who have chronic breathing problems. It may include
• An exercise program Disease management training Nutritional counseling Psychological counseling
• A lung transplant, as a last resort for people who have severe symptoms that have not gotten better with medicines

If you have chronic bronchitis, it's important to know when and where to get help for your symptoms. You should get emergency care if you have severe symptoms, such as trouble catching your breath or talking. Call your health care provider if your symptoms are getting worse or if you have signs of an infection, such as a fever.

Can chronic bronchitis be prevented?

From: MedlinePlus, National Library of Medicine

Since smoking causes most cases of chronic bronchitis, the best way to prevent it is to not smoke. It's also important to try to avoid lung irritants such as secondhand smoke, air pollution, chemical fumes, and dusts.

Which doctor should you see?

The suggested department for discussing Chronic Bronchitis is Pulmonology, with a pulmonologist / chest physician as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• What is the likely explanation for the breathing symptoms?
• Would a breathing test or another investigation change management?
• If symptoms worsen, what written action plan should be followed?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
