Pneumonia, What is it?

Pneumonia begins when a virus, fungus or bacteria enters your lungs. (if it enters the two lungs, it is called double pneumonia) This causes the small sacs inside the lungs to become inflamed and fill with fluid or pus. If you are healthy and treat the right way, it usually does not become serious. However, it can be dangerous for children, the elderly and people with health problems that affect the immune system.

How to handle

Most of the time, your body filters out the germs that air carries into your lungs. Coughing, for example, helps keep germs out. If they go in, your immune system usually fights them before you get sick, if the germs really are strong or your immune system can not deal with them, your lungs can become infected. When your immune system sends cells to attack these germs, your lungs become inflamed, becoming a pneumonia.


You may have a high fever, chills, shortness of breath and chest pains in the breath. You will also likely have a deep cough that does not go away and brings a thick liquid called phlegm. If you are able to do your daily activities with these symptoms, you may have “walking pneumonia” which is often caused by a certain type of bacteria called Mycoplasma pneumoniae. But if your symptoms are worse than this, you should consult your doctor.

Causes: Bacteria

Some of these tiny organisms are a natural and healthy part of your body, as in your gut where they help digest food. Others may make you sick. Most cases of pneumonia are bacteria that can be combated with antibiotics.

Cause: Virus

The flu virus is the most common cause of viral pneumonia in adults, but any virus that infects your mouth, nose, throat or lungs can lead to this. The symptoms are usually milder than with bacterial pneumonia, and your body usually fights for one to three weeks.

Cause: Fungus

Some of these are useful: mushrooms for example are a type of fungus, but some type of fungus can cause pneumonia. Antifungal medicines are usually used for treatment, but people with HIV or AIDS or taking medicines that weaken the immune system, for example cancer medication, may develop pneumocystosis. which is more dangerous and difficult to treat.


You may not notice that you have pneumonia. It can look like a lot with a cold or the flu while not moving. Your doctor will ask about your symptoms and when they started, and he will listen to your lungs for crackling or wheezing. He may want a chest x-ray to get an image of the lungs. With that, you can tell with certainty if you have pneumonia, but it will not show what is causing it.

Bacteria, Virus, or Fungus?

It is not always easy to discover the cause of pneumonia. Even a urine test can help the doctor figure out the cause. Some questions like, recent trips, hobbies, animals or sick people who had recent contact can help.


Vaccines can protect against some types, good habits also help, keep hands and face clean with soap or alcohol to ward off the germs that cause pneumonia. Healthy eating and an exercise routine help keep your immune system up. And do not smoke, smoking makes it hard for your body to keep bacteria and germs away from your lungs.
