Overview
Chronic bronchitis is a type of lung disease where the airways in your lungs stay inflamed and irritated for a long time. This makes your airways produce extra mucus, leading to a persistent cough. To be diagnosed with chronic bronchitis, you need to have a cough with mucus for at least 3 months each year for 2 years in a row.
This condition is part of a group of lung diseases called chronic obstructive pulmonary disease (COPD). About 16 million Americans have COPD, and chronic bronchitis affects millions of people worldwide. The condition makes it harder to breathe and can seriously impact your daily activities.
Chronic bronchitis is different from acute bronchitis, which is short-term and usually goes away on its own. With chronic bronchitis, the inflammation in your airways doesn't go away completely. Over time, this can cause permanent damage to your lungs and make breathing problems worse.
The damage to your airways happens slowly. Your cilia, which are tiny hairs that sweep mucus out of your lungs, get damaged and stop working properly. This means mucus builds up in your airways and stays there for a long time. Your body tries to clear this mucus by making you cough repeatedly.
Symptoms & Signs
The symptoms of chronic bronchitis develop slowly over time and tend to get worse during flare-ups. Many people don't realize they have the condition until it becomes more severe.
Primary Symptoms
Persistent cough - A daily cough that produces thick, sticky mucus (sputum) that may be clear, white, yellow, or green
Shortness of breath - Difficulty breathing, especially during physical activities or exercise
Chest tightness - Feeling like there's pressure or squeezing in your chest area
Wheezing - A whistling or squeaky sound when you breathe, similar to signs of asthma in kids
Your cough is usually the worst when you wake up in the morning. This happens because mucus builds up in your lungs while you sleep. As the day goes on, you clear some of the mucus by coughing, so the cough may get a little better. During winter months or when you have a cold, your symptoms often get much worse.
When to Seek Care
You should contact a healthcare provider if your cough lasts more than 3 weeks, if you're coughing up blood, or if you have a fever along with your symptoms. When should you go to urgent care for a cold can help you understand when symptoms need immediate attention.
Getting tired easily or having less energy than usual could also be a sign that you need medical help. These symptoms mean your lungs aren't getting enough oxygen to your body.
When to Seek Immediate Care
Call emergency services if you have severe difficulty breathing, chest pain, or if your lips or fingernails turn blue.
Causes & Risk Factors
Age
Most common in people over 40, with risk increasing with age
Genetics
Family history of COPD or lung disease increases your risk
Lifestyle
Smoking, poor diet, lack of exercise, and repeated lung infections
Other Conditions
Asthma, frequent respiratory infections, or acid reflux disease

Diagnosis
Medical History & Physical Examination
Your doctor will ask about your symptoms, smoking history, and exposure to lung irritants at work or home. They'll want to know how long you've had a cough and what your mucus looks like. During the physical exam, your doctor will listen to your lungs with a stethoscope to check for abnormal sounds like wheezing or crackling.
The doctor will also check how well you can breathe and may ask you to walk around to see if physical activity makes your symptoms worse. They'll look at your fingernails and lips to see if they have a bluish color, which could mean you're not getting enough oxygen.
Diagnostic Testing
Spirometry - A breathing test that measures how much air you can breathe in and out and how fast you can blow it out
Chest X-ray or CT scan - Pictures of your lungs to check for damage, inflammation, or other problems
Blood tests - Check oxygen levels in your blood and look for signs of infection or other conditions
Treatment Options
Treatment for chronic bronchitis focuses on managing symptoms, preventing flare-ups, and slowing down lung damage. The goal is to help you breathe easier and maintain a good quality of life.
Conservative Treatments
Bronchodilators - Medications that open up your airways to make breathing easier, similar to fluticasone inhaled treatments used for other respiratory conditions
Anti-inflammatory medications - Help reduce swelling and inflammation in your airways
Mucus thinners - Make it easier to cough up and clear mucus from your lungs
Most people with chronic bronchitis use inhalers to take their medications directly into their lungs. You may need to use your inhaler every day, even when you feel fine. Your doctor might prescribe different medications for when you feel good and different ones for when you have a flare-up.
Advanced Treatments
Oxygen therapy - Extra oxygen through a mask or nasal tubes when blood oxygen levels are too low
Pulmonary rehabilitation - A program that includes exercise training, breathing techniques, and education about managing your condition
Surgery - In severe cases, procedures like lung volume reduction or lung transplant may be considered
Treatment plans are different for each person based on how bad your symptoms are and how much your lungs are damaged. Your doctor may change your treatment over time as your condition changes. It's important to work closely with your healthcare team to find the treatments that work best for you.
Living with the Condition
Daily Management Strategies
Take your medications as prescribed and keep track of your symptoms in a diary. Use a humidifier to keep the air moist, which can help loosen mucus. Practice breathing exercises and techniques you learn in pulmonary rehabilitation. Stay up to date with vaccinations for flu and pneumonia to prevent infections that could make your symptoms worse.
Having a written action plan from your doctor helps you know what to do when your symptoms get worse. Keep your rescue inhaler with you at all times in case you need it suddenly. Avoid triggers like strong perfumes, smoke, and cold air that can make your cough worse.
Exercise & Movement
Regular, gentle exercise can help improve your breathing and overall health. Start with short walks and gradually increase your activity level as tolerated. Swimming and stationary biking are good options because they're easier on your lungs. Avoid exercising outdoors on days when air pollution is high or during extreme weather conditions.
Talk to your doctor before starting any new exercise program. They can help you find safe activities that work for your fitness level. Even a little bit of movement is better than staying still all day.
Prevention
Quit smoking - This is the most important step to prevent further lung damage and may help slow the progression of the disease
Avoid secondhand smoke - Stay away from places where people are smoking and don't allow smoking in your home or car
Protect yourself from air pollution - Stay indoors on high pollution days and use air purifiers in your home
Get vaccinated - Keep up with flu shots and pneumonia vaccines to prevent respiratory infections that can worsen your condition
Wearing a mask when you're around dust, fumes, or other irritants can also protect your lungs. If you work in a job with air pollution or dust, talk to your employer about safety measures. Even simple steps like keeping windows closed on high pollution days can help protect your lungs.
Frequently Asked Questions
There's no cure for chronic bronchitis, but treatments can help manage symptoms and slow down lung damage. Quitting smoking is the most effective way to prevent the condition from getting worse.
