Pneumonia Causes

The main cause of pneumonia is the infection of the lung tissue by one of many different microorganisms including bacteria, viruses, fungi and some parasites. These may be present in the body for some time before causing illness.

You may get pneumonia from the germs present in food, liquids and chemicals. In some cases, it is caused by breathing in small droplets containing the organisms that cause pneumonia. These organisms come into air from an infected person, when the person coughs or sneezes. In other cases, pneumonia is caused when bacteria or viruses that are usually present in the mouth, throat, or nose inadvertently enter the lung.

Though, pneumonia can be caused to anyone at any age, but very young and very old people are the most susceptible to pneumonia. Pneumonia very easily develops after an illness such as flu or cold.

Pneumonia is of two types according to the locations in the lung:

1) A lobar pneumonia- It affects a section of the lung.

2) A bronchial pneumonia -It affects the lungs in patches around the tubes, which bring the air into the lungs.

Some other causes of the pneumonia are:

• Excessive Smoking.
• Heavy Drinking.
• Heart Failure.
• Diabetes.
• Having a Lung Disease.
