Lung Disease Overview


Lung disease is the most common disease in the world. Tens of millions of people have been affected only in the united states. The working of the lungs is a complex system in human function, which expands several times a day to let the carbon dioxide out and get inside the fresh air of oxygen. Lung disease can happen when any part of the lungs is not performing well in this system. Many common ways of getting lung disease is smoking, infection, and genetic cause. 

Airways affected due to Lung diseas

Our windpipe is divided into several branches, which we call Bronchi, into smaller tubes through your lungs. Some of the diseases that affect airways include. 


Chronic obstructive pulmonary disease

Chronic bronchitis 


Acute bronchitis 

Cystic fibrosis


In asthma, our airways get inflated, that cause wheezing and shortness of breath. Some symptoms that can trigger  Asthma are allergies, infections, or pollution.

Chronic obstructive pulmonary disease

If you have been suffering from this disease, you will suffer from the problem of exhaling as you do in the standard form. 

Chronic bronchitis 

Cigarette smoking is the leading cause of chronic bronchitis disease. Air pollution and the environment in which you work may play a vital role. Additionally, you will feel a wet cough if you suffer from such a disease. 


When the air gets trapped in the lungs, this causes a disease called Emphysema.

Acute bronchitis.

Some of the viruses cause sudden infection in the air passage. 

Cystic fibrosis

When you cannot get through the mucous out of the bronchi, this leads to further lung infections. 

Lung Diseases Affecting the Air Sacs (Alveoli)

Our tubes carry air into sacs called alveoli. Most of these air sacs make lung tissues. Lung diseases that affect our alveoli include these diseases;


When bacteria damages your alveoli by the infection, you come across a disease called pneumonia. This disease is also the one that affected millions of people in the world during covid 19;


When pneumonia gets worsens slowly, it leads to tuberculosis. Tuberculosis is caused by the bacteria called mycobacterium tuberculosis.

Lung cancer

 This type of disease can occur in any part of the lungs, mainly near the air sacs called Alveloii. Furthermore, lung cancer has several varieties. 

Acute respiratory distress syndrome

Thai type of disease is caused by sudden damage to our lungs. Most of the people who have been suffering from such a disease need machines like ventilators to breathe. 


If you have been suffering from this disease, you will feel pain while inhaling—for instance, black lung disease from coal dust and asbestosis from asbestos dust. 


With time, a lot of new diseases are being introduced. The disorders which have cur these days were once incurable, but with the help of painstaking efforts, if the scientists successfully got the treatment, prevention is better than, ms of the disease can be prevented by taking care of ourselves. However, you should not need to worry because doctors are there to treat most of the conditions that have become common these days.
