5 Things Nobody Told You About Pneumonia Symptoms-causes, Diagnosis & Treatment


Lungs with Pneumonia are an infection that inflames the air sacs in one or both lungs.

The air sacs may fill with fluid or pus (purulent substance ), causing cough with phlegm or pus, fever, chills, and difficulty breathing.

A variety of organisms, such as bacteria, viruses, and parasites, may lead to pneumonia.

Pneumonia can range in seriousness from mild to life-threatening. It is most serious for babies and young children, individuals older than age 65, and people with health problems or weakened immune systems.

Symptoms of Pneumonia:

The signs and symptoms of pneumonia vary from mild to severe, depending on factors like the type of germ causing the infection, and your age and general health.

Mild signs and symptoms frequently are much like those of a cold or flu, but they last longer.

Signs and symptoms of pneumonia may include:

  • Confusion or changes in psychological awareness (in adults age 65 and older).
  • Cough, which may create phlegm.
  • Fever, sweating, and shaking chills.
  • Lower than normal body temperature (in adults older than age 65 and individuals with weak immune systems).
  • Nausea, vomiting, or diarrhea.
  • Shortness of breath.

Newborns and infants may not show any indication of the infection. Or they may vomit, have a fever and cough, appear tired or tired and without energy, or have trouble breathing and eating.

When to see a doctor:

See your doctor if you have trouble breathing, chest pain, persistent fever of 102 F (39 C) or greater, or persistent cough, particularly if you’re coughing up the pus.

It’s especially important that individuals in those high-risk groups visit a doctor:

  • Adults are older than age 65.
  • Children are younger than age 2 with symptoms and signs.
  • People with an underlying health condition or weakened immune system.
  • People receiving chemotherapy or taking drugs that suppress the immune system.

For some older adults and individuals with heart failure or chronic lung issues, pneumonia may quickly become a life-threatening condition.

Causes of Pneumonia:

Many germs may cause pneumonia. The most common are bacteria and viruses from the air we breathe.

Your body usually prevents these germs from infecting your lungs. However, sometimes these germs can overpower your immune system, even though your health is usually good.

Pneumonia is classified according to the types of germs that make it where you have the infection.

  • Community-acquired pneumonia. It happens outside of hospitals or other health care facilities. This type of pneumonia may occur by itself or after you have had a cold or the flu. It may affect 1 part (lobe) of the lung, a condition called lobar pneumonia.
  • Bacterialike creatures. Mycoplasma pneumonia also can lead to pneumonia. It typically produces milder symptoms than do other types of pneumonia.

Walking pneumonia is an informal name given to this type of pneumonia, which generally is not severe enough to require bed rest.

The fungi that cause it may be found in soil or bird droppings and also vary based upon geographic location.

Viruses, such as COVID-19:

A few of the viruses that cause colds and the flu can lead to pneumonia. Viruses are the most common cause of pneumonia in children younger than 5 decades.

Viral pneumonia is usually moderate. But in some cases, it can become very severe.
Coronavirus 2019 (COVID-19) may lead to pneumonia, which can become severe.

  • Hospital-acquired pneumonia- Is a bacterial infection that occurs in people who live in long-term care centers or who take care in outpatient clinics, including kidney dialysis centers.
  • Aspiration pneumonia– It happens when you inhale food, drink, vomit, or saliva into your lungs. Aspiration is more likely if a person disturbs your regular gag reflex, such as a brain injury or swallowing issue, or excessive use of alcohol or drugs.

Risk Factors of Pneumonia:

Pneumonia can influence anyone. However, both age groups at highest risk are:

  • Children who are two years old or younger.
  • Individuals That Are age 65 or older

Other risk factors include:

  • Being hospitalized– You are at greater risk of pneumonia if you are in a hospital intensive care unit, particularly if you’re on a machine that helps you breathe (a ventilator).
  • Chronic disease-You’re more likely to get pneumonia when you have asthma, chronic obstructive pulmonary disease (COPD), or heart disease.
  • Smoking- Smoking damages your body’s natural defenses against the bacteria and viruses that cause pneumonia.
  • Weakened or suppressed immune system– People who have HIV/AIDS, who have had an organ transplant, or who receive chemotherapy or long-term steroids are in danger.

Complications of Pneumonia:

Despite treatment, some people with pneumonia, especially those in high-risk classes, may experience complications, for example:

  • Bacteria in the blood (Bacteremia). Bacteria that enter the bloodstream from your lungs can spread the infection to other organs, possibly causing organ failure. If your pneumonia is severe or you’ve got chronic underlying lung ailments,
  • Difficulty Breathing-you may have trouble breathing in enough oxygen. You may want to be hospitalized and use a breathing machine (ventilator) while your lung heals.
  • Fluid accumulation around the lungs (pleural effusion). Pneumonia may lead to the fluid accumulate in the thin space between layers of tissue that line the lungs and chest cavity (pleura).

If the fluid becomes infected, then you may have to have it emptied through a chest tube or removed with surgery.

  • Lung abscess- An abscess happens if pus creates in a pit in the lung. An abscess is generally treated with antibiotics.

At times, surgery or drainage with a long needle or tube set into the abscess is required to remove the pus.

Prevention of Pneumonia:

To help prevent pneumonia:

  • Get vaccinated. Vaccines are available to prevent some types of pneumonia and the flu. Talk to your doctor about getting those shots.

The vaccination guidelines have shifted over time so make sure that you examine your vaccination status with your doctor even in the event that you remember previously getting a pneumonia vaccine.

  • Ensure children get vaccinated. Doctors recommend a different pneumonia vaccine for children younger than age two and for children ages 2 to 5 years who are at particular risk of pneumococcal disease.

Children who attend a group child care center should also get the vaccine. Doctors also recommend flu shots for children older than 6 months.

  • Practice good hygiene. To protect yourself against respiratory infections that sometimes cause pneumonia, wash your hands frequently or use an alcohol-based hand sanitizer.
  • Do not smoke. Smoking damages your lungs’ natural defenses against respiratory infections.
  • Keep your immune system strong. Get enough sleep, exercise regularly, and eat a healthy diet.

Diagnosis of Pneumonia:

Your doctor will start by asking about your medical history and doing a physical examination, including listening to your lungs with a stethoscope to check for abnormal bubbling or crackling sounds that suggest pneumonia.

Following some Suggested Test by Physician if suspected:

  • Blood tests are utilized to confirm an infection and also to attempt to recognize the kind of organism causing the infection.
  • Chest X-ray. This assists your doctor to diagnose pneumonia and determine the degree and location of the infection. However, it can’t tell your doctor what kind of germ is causing pneumonia.
  • Pulse oximetry-This measures the oxygen level in your blood. Pneumonia can stop your lungs from transferring enough oxygen into your bloodstream.
  • Sputum test. A sample of the fluid in your lungs (sputum) is obtained after a deep cough and analyzed to help pinpoint the cause of the infection.
Your doctor might order extra tests if you are older than age 65, are at the hospital, or have severe symptoms or health conditions. These may include:
  • CT scan. If your pneumonia isn’t clearing as fast as expected, your doctor may suggest a chest CT scan to obtain a more comprehensive picture of your lungs.
  • Pleural fluid culture. A fluid sample is taken by placing a needle between your ribs in the thoracic area and examined to help determine the type of infection.

Treatment of Pneumonia:

Remedy for pneumonia involves treating the infection and preventing complications. Individuals who have community-acquired pneumonia usually can be treated at home with medication.

Even though most symptoms facilitate in a couple of days or weeks, the feeling of tiredness can persist for a month or more.

Certain treatments rely on the kind and seriousness of your pneumonia, your age, and your general health. The choices include:

Additionally, you should be aware that very few studies have looked at whether over-the-counter cough medications lessen coughing caused by pneumonia.

If you would like to try out a cough suppressant, use the lowest dose that helps you rest.

Pain Reliever:

You may take these as necessary for discomfort and fever. These include drugs such as aspirin, ibuprofen (Advil, Motrin IB, others), and acetaminophen (Tylenol, others).


You may Have to Be hospitalized if:

  • You’re older than age 65.
  • Your systolic blood pressure is under 90 millimeters of mercury (mm Hg) or your diastolic blood pressure is 60 mm Hg or below.
  • If breathing is rapid (30 breaths or a moment ).
  • Fever is under normal.
  • Heart rate is below 50 or above 100.

You may be admitted to the intensive care unit if you need to be placed on a breathing machine (ventilator) or if your symptoms are severe.

Children may be hospitalized if:

  • They’re younger than age two months.
  • If they are lethargic or excessively sleepy.
  • In case of having difficulty breathing.
  • If symptoms of low blood sugar levels.
