What is the Causes, Types and Symptoms of Pneumonia?
Pneumonia is a respiratory infection that usually inflames the lung through bacteria. During a pneumonia attack, the air sacs, also called alveoli, become filled with inflammatory cells. These can then cause the breathing passages to swell and make it difficult to breathe.
Pneumonia attacks tend to occur more often when the person has not had any immunization in a long period. Pneumonia is the inflammation of the tissue in one or both lungs. This is usually caused by a bacterial infection. At the end of the breathing tubes in the lungs are clusters of tiny air sacs. If a person has pneumonia, these tiny sacs will become inflamed and fill up with fluid.
There are many different things that can cause pneumonia
There is usually a combination of factors that can be responsible for causing the infection. The most common factor is a weak immune system. There are many ways that your immune system can be weakened. One of the main causes of pneumonia is being around sick people who have other diseases that can weaken the immune system.
Other reasons include smoking cigarettes or using tobacco products. Other things include exposure to certain chemicals, like asbestos. The good thing is that pneumonia can be treated and if caught early, you can have your lung removed and that will end your suffering.
Once the lung is removed, the treatment is usually very simple. Just have the doctor put a Band-Aid on it and leave it alone. It should heal itself on its own, and you should never have to worry about the problem again. If you have pneumonia and it is still not gone, your doctor will want to test you to see why you had it and determine the exact cause.
Of course, the cause of pneumonia could be something else and they may have to perform surgery. Pneumonia can cause serious problems if left untreated, so if you think you have pneumonia and you do not have it yet, get yourself checked out. Get treated right away!
Pneumonia can be Classified in 2 different ways
Pneumonia can be classified in the different subheading, most commonly are where the pneumonia was acquired (hospital versus community), but may also by the area of the lung affected or by the causative organism.
There is also a combined clinical classification, which combines factors such as age, risk factors for certain microorganisms, the presence of underlying lung disease or systemic disease and whether the person has recently been hospitalized.
Pneumonia Acquired by Location
Community Acquired Pneumonia
This is infectious pneumonia in a person who has not recently been hospitalized. Community-acquired pneumonia is the most common type of pneumonia. The most common causes of community-acquired pneumonia vary depending on a person’s age, but they include Streptococcus pneumoniae, viruses, the atypical bacteria, and Haemophilus influenzae.
Streptococcus pneumoniae is the most common cause of community-acquired pneumonia worldwide. Gram-negative bacteria cause community-acquired pneumonia in certain at-risk populations. Community-acquired pneumonia is the 4th most common cause of death in the UK and the sixth in the USA.
There is a term, walking pneumonia that has been used to describe a type of community-acquired pneumonia of less severity (because the sufferer can continue to “walk” rather than requiring hospitalization). The walking pneumonia is usually caused by the atypical bacterium, Mycoplasma pneumoniae.
Hospital Acquired Pneumonia
This type of pneumonia is also called Nosocomial Pneumonia, this is a type of pneumonia acquired during or after hospitalization for another illness or procedure with onset at least 72 hrs after admission. The causes, microbiology, treatment and prognosis of this pneumonia type is different from those of community-acquired pneumonia.
According to reports, about 5% of the patients admitted to a hospital for other causes subsequently develop pneumonia. Hospitalized patients for pneumonia may have many risk factors for pneumonia, including mechanical ventilation, prolonged malnutrition, underlying heart and lung diseases, decreased amounts of stomach acid, and immune disturbances.
Hospital acquired pneumonia microorganisms may include resistant bacteria such as
- Methicillin Resistant Staphylococcus Aureus (MRSA)
- Enterobacter, and
Because people with hospital-acquired pneumonia usually have underlying illnesses and are exposed to more dangerous bacteria, and this tends to be more deadly than community-acquired pneumonia. Ventilator-associated pneumonia is a subset of hospital-acquired pneumonia. Ventilator-associated pneumonia (VAP) is a type of pneumonia which occurs after at least 48 hours of intubation and mechanical ventilation.
Pneumonia by Cause
- Bronchiolitis obliterans organizing pneumonia
- Chemical pneumonia
- Eosinophilic pneumonia
- Necrotizing pneumonia
- Aspiration pneumonia
- Dust pneumonia
- Opportunistic pneumonia
- Severe acute respiratory syndrome
- Double pneumonia (bilateral pneumonia)
Pneumonia by area of lung affected
This is the initial descriptions of pneumonia focused on the anatomic or Pathologic appearance of the lung, either by direct inspection at autopsy or by its appearance under a microscope.
- Lobar Pneumonia: an infection that only involves a single lobe, or section, of a lung. Lobar pneumonia is often due to Streptococcus pneumoniae (though Klebsiella pneumoniae is also possible
- Multilobar Pneumonia: this involves more than one lobe, and it often causes a more severe illness
- Bronchial Pneumonia: this affects the lungs in patches around the tubes (bronchi or bronchioles
- Interstitial Pneumonia: this involves the areas in between the alveoli, and it may be called “interstitial pneumonitis.” It is more likely to be caused by viruses or by atypical bacteria.
This is traditionally, clinicians have classified pneumonia by clinical characteristics, dividing them into “acute” (less than three weeks duration) and “chronic” pneumonias. This is useful because chronic pneumonias tend to be either non-infectious, or mycobacterial, fungal, or mixed bacterial infections caused by airway obstruction. An acute pneumonias are further divided into the
- Classic bacterial bronchopneumonias (such as Streptococcus pneumoniae)
- Atypical pneumonia (such as the interstitial pneumonitis of Mycoplasma pneumoniae or Chlamydia pneumoniae)
- Aspiration pneumonia syndromes.
The combined clinical classification, now the most commonly used classification scheme, attempts to identify a person’s risk factors when he or she first comes to medical attention. The advantage of this classification scheme over previous systems is that it can help guide the selection of appropriate initial treatments even before the microbiologic cause of the pneumonia is known.
When the lung becomes affected, the person’s immune system will usually fight off the infection. However, sometimes the immune system is weak and the pneumonia takes over and the body is not able to fight it off. This results in pneumonia and the patient usually dies within a few days. The lungs may have to be removed. In some cases, the patient can survive for a while but does not get better and is not treated properly.
The most common reason for pneumonia is because of a weak immune system, such as from chemotherapy. Other causes of pneumonia are exposure to certain chemicals, such as asbestos, and the like. The important thing is to recognize that pneumonia can happen and be treated. Although this type of pneumonia can be dangerous, it usually goes away on its own and there is no serious danger involved.
Treating the infection of Pneumonia is usually done by antibiotics
If left untreated, pneumonia can lead to a more severe complication called secondary pneumonia, which can cause the person to pass away while the body heals itself. If you suspect that you may have pneumonia, seek medical help. You can also seek out professional advice from your doctor about treating the infection, whether at home or at the hospital.
Many people are using natural remedies and home remedies to treat their pneumonia, but the best way to get rid of the infection is to seek medical attention. The best way to do this is to consult a doctor and get tested to make sure that you have pneumonia.
It is a good idea to seek out the internet and find out all you can about pneumonia and how to prevent it from happening to you. If you are not sure if you have pneumonia, it is best to go see a doctor and get tested for it. Your doctor will give you more information about your condition and tell you what to do next.
