Pneumonia is an inflammation of the lungs. Usually the inflammation is caused by an infection, but it can also be caused by breathing certain chemical fumes. It's a more common problem than most people think. Usually pneumonia is a mild disease, but some forms are very dangerous. In all cases, you'll need to seek care from your health care provider.
Pneumonia can affect just one lobe of the right or left lung, a whole lung, or both lungs.

Bronchitis is a respiratory disease in which the mucus membrane in the lungs' bronchial passages becomes inflamed.
As the irritated membrane swells and grows thicker, it narrows or shuts off the tiny airways in the lungs, resulting in coughing spells that may be accompanied by phlegm and breathlessness.
The disease comes in two forms: acute (lasting from one to three weeks) and chronic (lasting at least 3 months of the year for two years in a row).
People with asthma may also have asthmatic...
Many different kinds of germs infect the lungs and cause pneumonia. Infected lungs leak fluids and shed dead cells. This material clogs up air sacs and makes it hard for the lungs to do their job of getting oxygen into the blood. Without enough oxygen, none of the cells in your body work as they should.
Pneumonia generally lasts about two weeks. However, you may feel tired or weak for a month or more after the lungs clear up.
What Causes Pneumonia?
Viruses cause many cases of pneumonia, but bacteria are the most common cause of pneumonia in adults over the age of 30. Fungi can also cause pneumonia.
Many of these germs are all around us. They usually can't get past a healthy person's natural defenses. Pneumonia is most common in those with weaker or compromised immune systems, elderly people, cigarette smokers, alcoholics, and people suffering from other diseases such as the flu.
