What Is Pneumonia?

PneumoniaInfection causing fluid or pus to fill in the alveoli is known as pneumonia. Bacteria, virus or fungus can cause the problem. The germs resulting in the lung infection are contagious. So, it can spread from one person to another and result in lung infection. In both viral and bacterial pneumonia, the condition can spread through inhalation of droplets from a cough or sneeze of an infected person. It is a serious problem that needs immediate attention.

  • Pain in the chest during coughing
  • Fatigue
  • Confusion
  • Changes in awareness (it is seen in older people)
  • Fever or chills
  • Excess sweating
  • Nausea
  • Vomiting
  • Low body temperature (in people with a weakened immune system or older people above 65 years of age)
  • Diarrhea
  • Shortness of breath

Signs Of Pneumonia In Children

Newborns or infants can also suffer from a lung infection. They may not show signs at first. But, some children can exhibit the following signs:

  • Children younger than two years of age
  • People suffering from serious health issues
  • Individuals with a weak immune system
  • People taking medication to suppress the immune system
  • Cancer patients undergoing chemotherapy

Causes Of Pneumonia

Pneumonia affects you due to the germs, which attack your lungs, causing infection and inflammation. In most cases, bacteria or virus can result in lung infection. The bacteria and virus present in the air you breathe can result in the condition. Your body’s immune system prevents the germs from affecting your lungs. But, due to some reasons, the germs can overcome your immune system and attack the germs. It can affect you even without any health complication.

Types Of Pneumonia

Pneumonia is classified into different types based on the germs causing the problem and the specific location you got the infection. The different types are:

Community-Acquired Pneumonia

It is the common type of lung infection occurring outside of the health care facilities (like hospitals). The main causes of the type of problem are:

Bacteria

It is the common cause of lung infection. Bacteria called streptococcus pneumoniae can affect a person after suffering from cold or flu. In most cases, the bacteria affects the one part or lobe of the lung. It results in the condition known as lobar pneumonia.

streptococcus pneumoniae

Some people can also suffer from infection in the lung caused by bacteria-like organisms. Mycoplasma pneumoniae is one such organism affecting the lungs and causing inflammation. It usually has milder symptoms compared to other types of lung infections. It is also known as walking pneumonia as the person affected by the condition does not need bed rest.

Fungi

It is the lung infection affected people with chronic health complications or a weakened immune system. It also affects people who have inhaled a large dose of external organisms. You can find fungi in the soil or in bird droppings. Its presence varies depending on the geographical location.

Viruses

Cold or flu occurring due to the virus can also trigger lung infection. It is a common problem in children who are young. So, children younger than five years of age face the risk of such infections. In usual cases, the infection of the lung caused by a virus can cause mild symptoms. But, in some cases, the issue can become severe.

As the name suggests, you catch the infection during your stay in the hospital for other illnesses. Hospital-acquired pneumonia is serious as the bacteria triggering it has high resistance to antibiotics. It is because the affected people are already sick. The condition is prevalent among patients who are on ventilators (breathing machines) in the intensive care unit.

Health Care-Acquired Pneumonia

It is the type of lung infection caused by bacteria that affects people who live in long-term healthcare facilities. The also affects people receiving care in outpatient clinics like kidney dialysis centers. It is caused by bacteria with more resistance to antibiotics. So, people need to maintain caution.

Aspiration Pneumonia

Aspiration Pneumonia
Aspiration Pneumonia

It is the infection affecting your lungs when you inhale food, drink, saliva or vomit. It mostly occurs when something causes disturbance to your normal gag reflex. So, the following issues can put you at risk of the specific type of pneumonia:

  • Excessive alcohol or drug use
  • Brain injury
  • Swallowing problems

Risk Factors Associated With Pneumonia

Anyone can suffer from a lung infection. But, some people are prone to the problem compared to others. The factors leading to the infection are:

Age

People coming under two age group of people face the highest risk of suffering from the issue. They are:

  • Children who are two years or younger
  • Old people above 65 years of age

Hospitalization

People who are hospitalized for serious illness and stay in the intensive care unit can face more risk of lung infection. It is particularly true for patients who are hooked on a ventilator to breathe properly.

  • Oxygen therapy maintains the oxygen levels in the blood. It is received through a face mask, nasal tube, or ventilator depending on the severity of your infection.

Complications Due To Pneumonia

You can experience complications due to lung infection. Some people coming under the high-risk group can experience the problem even with treatment. The possible complications include:

Bacteremia

Bacteremia is the condition resulting in the presence of bacteria in the bloodstream. The bacteria enter your blood from the lungs. So, it can spread bacteria to other organs and cause infection. It results in organ failure.

Difficulty To Breathe

In severe cases of pneumonia or you suffer from chronic lung diseases, it causes trouble breathing. It results in trouble getting enough oxygen. Therefore, the condition can result in hospitalization. The doctor can use ventilator (breathing machine) until the lung heals.

Pleural Effusion

Pleural effusion is condition causing fluid accumulation around the pleura. The fluid accumulates around the thin space between the tissue layers that line your chest cavity (pleura) and lungs. When the fluid becomes infected, it can cause severe complications. You need a doctor’s assistance to drain the fluid through a chest tube. In some cases, the condition needs surgery to drain the fluid.

Lung Abscess

Abscess formation is another complication arising due to lung infection. The pus formation in the lung cavity is known as an abscess. Your doctor treats the condition with antibiotics.
