How does bronchitis affect human body?

Bronchitis is an inflammation of the bronchi, which are the large airways that carry air to and from the lungs. This inflammation causes swelling, mucus production, and narrowing of the airways, which can restrict airflow and cause difficulty breathing. Symptoms of bronchitis may include cough, chest tightness, shortness of breath, wheezing, sore throat, fatigue, body aches, and chills.

Here are some additional details on how bronchitis affects the human body:

* The inflammation of the bronchi can cause the airways to become swollen and narrowed. This narrowing of the airways makes it more difficult for air to move in and out of the lungs, which can lead to shortness of breath, wheezing, and difficulty breathing.

* The inflammation can also cause the production of mucus, which is a thick, sticky fluid that can plug up the airways and make it difficult to breathe. Mucus production can also lead to a cough that is productive of yellow or green phlegm.

* In some cases, bronchitis can lead to a buildup of pressure in the chest, which can lead to chest pain.

* If the bronchitis is severe, it can also lead to respiratory failure. Respiratory failure occurs when the lungs are unable to function properly and deliver oxygen to the body, which can lead to death.

Most cases of bronchitis are caused by respiratory infections, such as the common cold, influenza, and respiratory syncytial virus (RSV). However, it can also be caused by other things, such as exposure to irritants, such as smoke and pollution, and allergic reactions.

In most cases, bronchitis is a self-limited condition that will resolve in a few weeks without specific treatment. However, for people with severe bronchitis or underlying medical conditions, treatment may be needed to help alleviate symptoms and prevent complications. Treatment options may include rest, fluids, over-the-counter medications, such as cough suppressants and expectorants, and prescription medications, such as antibiotics and inhalers.
