Lung Disease

What is lung disease?

The lungs are part of the respiratory system. Its function is to supply oxygen and remove the dirty air so that the whole system and organs can function properly. The lungs are located on both sides of the chest. They are separated by a mediastinum (a cavity containing the esophagus, the trachea, and the heart), and are protected by the ribs.

Lung disease is a condition that makes the lungs cannot function normally. Some of the most common are asthma, chronic obstructive pulmonary disease (COPD), pneumonia, tuberculosis, and lung cancer. The disease can be derived from genetic, smo**king habit, air pollution, and exposure to chemicals in the workplace.

These diseases generally show symptoms of difficulty breathing, chronic cough, wheezing, and chest pains. Severe conditions can cause patients with a bloody cough, chronic infections that do not heal after treatment, and respiratory failure.

Types of lung diseases

The following are the kinds of diseases that can attack the lungs:


Lung Disease Types

Pneumonia is an infection that causes the air sacs in the lungs to become inflamed and swollen. Pneumonia is often referred to as wet lung, because in this condition, the lungs can be filled with liquids or pus.

This disease can also be caused by bacteria, viruses, and fungi that attack. However, in general, the most common attacks of pneumonia are Streptococcus bacteria and Mycoplasma Penumoniae bacteria.

In addition, the symptoms that can be caused by the inflammation of the lungs is that you will have a cough with phlegm to bleeding. In addition to that, pain and also feels tightness in the chest and you can experience a high fever even until your level of consciousness decreases.


Tuberculosis (TB) is a lung disease caused by the Mycobacterium tuberculosis bacteria. These bacteria don’t only attack the lungs, but can also spread to other parts of the body, such as bones, lymph nodes, central nervous system, and kidneys.


Bronchitis is an inflammation that occurs in the branches of the airways leading to the lungs or bronchus. One of the most frequent causes is viral infections.

Chronic obstructive pulmonary disease

Chronic obstructive Pulmonary disease (COPD) is a chronic pulmonary inflammation that causes the occurrence of airflow disorder both towards and from the lungs. There are two types of disorders that occur in COPD, namely chronic bronchitis and emphysema.


Asthma is a chronic disease characterized by inflammation and narrowing of the respiratory tract, causing shortness of breath.

Exposed to asthma is not only caused by infection in the lungs. Some asthma triggers are due to allergies to something, whether it’s food, beverages, certain medications, cold weather or allergens. The allergen itself meres something small which can be inhaled and causes narrowing of the respiratory tract.

Asthma disease suffered by each person can vary, it depends on the existing asthma attack. But of course, if you suffer from asthma you can’t leave it. Because, if the shortness of breath is quite heavy, life might be at stake.


Pneumothorax is the collection of air or gas in the pleural cavity located between the lungs and the thorax. This disease can occur suddenly in healthy people. But it can also attack someone who has a disease of complications in the lungs.

Legionnaires disease

Legionnaires disease is a pulmonary disease caused by the Legionella pneumophilia bacteria. Its infectious form is similar to pneumonia. The Legionella bacteria that cause this disease are stem-shaped bacteria found in most water sources. They multiply very quickly. They are found in plumbing systems or wherever the water can be flooded.

Symptoms are similar to pneumonia or other pneumonia, but sufferers also have diarrhea, abdominal pain, or jaundice.

This disease occurs often in people who are middle or older and can be serious or even cause death in people who have a weakened immune system.
