Bronchitis vs Bronchiectasis: What's the Difference?

    Bronchitis vs Bronchiectasis: What's the Difference?

    Bronchiectasis and bronchitis are both conditions associated with the lungs. While both are lung infections, they are different in a number of ways. Read on to learn all about bronchitis vs bronchiectasis.

    What is bronchiectasis?

    Bronchiectasis is a lung condition that occurs when the bronchial tubes of your lungs are enlarged permanently. The condition makes the airways permanently broadened and inflamed. This causes the excess production and accumulation of mucus in the lungs.

    This condition makes you more prone to infection and causes difficulty in breathing. Though there is no cure for the condition, proper treatment and a healthy lifestyle can help to manage it. Even if you have minor symptoms, it is important to treat as soon as possible to avoid further lung inflammation.

    What is bronchitis?

    Bronchitis, on the other hand, is a lung condition that occurs when the airways in the lungs become inflamed. This makes it difficult for you to inhale and exhale. In most cases of bronchitis, individuals cough up mucus.

    There are two types of bronchitis – acute and chronic. Acute bronchitis is a common condition that is mainly caused by cold or respiratory infections. While chronic bronchitis is a condition that causes inflammation of the airways and is often caused by smoking.

    This is the difference between bronchitis vs bronchiectasis. Since bronchiectasis and bronchitis are different from each other, their respective causes, symptoms, and treatments are also different. Let’s look into these differences.

    Difference between bronchitis vs bronchiectasis causes and symptoms

    Acute bronchitis is mainly caused because of viruses that cause cold and flu. The infection that begins with the nose slowly spreads through the throat and then the airway. While chronic bronchitis is mainly caused because of pollutants present in the air that harm your lungs. The pollutants can be dust, chemicals, etc. Other possible cause of chronic bronchitis is smoking.

    In this condition, it becomes difficult for you to breathe in and out. Common symptoms of acute and chronic bronchitis include cough which initially starts as dry cough and eventually turns into a wet cough causing difficulty in breathing, wheezing, and heaviness in the chest.

    Other symptoms of acute bronchitis include body pain, fever, runny nose, and sore throat. In most cases, even after the symptoms are cured, it might take a few days for the airways to heal completely. If the cough is persistent, it is advised to talk to your doctor. It might be an indication of some other health condition. In chronic bronchitis, there are chances of you having a cough that may last for several weeks.


    If you have existing lung infections or lung diseases, you are more likely to get bronchiectasis. And if you have a weak immune system, you may be at risk of getting the condition. If you have cystic fibrosis, you are more likely to get bronchiectasis. Cystic fibrosis is a condition that causes severe lung infection and that makes it difficult to breathe.

    Other possible causes of bronchiectasis are a severe infection or injury to the lungs.

    Common symptoms of bronchiectasis include difficulty in breathing, pain in the chest, wheezing, fatigue, weight loss, coughing up thick phlegm. The symptoms of bronchiectasis may take a lot of time to develop.

    If you come across any of the above symptoms seek medical help. It is important for early diagnosis of the condition for effective treatment. In some cases, bronchiectasis can change the shape and proper functioning of airways.
