Pneumonia: first symptoms, modern diagnostics and effective treatment

Pneumonia is an acute infectious inflammation of the lung tissue that can progress rapidly and lead to complications. Thousands of people seek medical attention every year with symptoms of pneumonia, and the disease can be particularly severe in at-risk groups. That is why early diagnosis of pneumonia, proper treatment, and timely prevention are key.

According to World Health Organization, pneumonia remains one of the leading causes of hospitalization among children under 5 years of age and older adults. The risk of complications is also significantly increased in adults with chronic diseases.

What is pneumonia in simple words?

Pneumonia is an inflammation of the alveoli in the lungs. The alveoli are small air sacs through which oxygen and carbon dioxide are exchanged. When they fill with fluid or purulent exudate, the body begins to experience a lack of oxygen.

The causes of pneumonia can be different:

• bacterial infection

• viral infection (flu, RSV, (COVID-19)

• fungal pathogens

• aspiration

Bacterial pneumonia is most often diagnosed in adults.

Symptoms of pneumonia: when to sound the alarm

Pneumonia may start as a common cold, but symptoms quickly worsen.

The main symptoms of pneumonia:

• high fever over 38°C

• severe cough (with phlegm or dry)

• chest pain when breathing

• dyspnea

• pronounced weakness

• rapid breathing

In older people, pneumonia may manifest itself atypically — without a high fever, but with severe weakness, confusion, or exacerbation of chronic diseases.

Pneumonia in children and the elderly

In children, pneumonia often develops after a viral infection. Signs that require immediate evaluation by a doctor include:

• intercostal space retraction

• rapid breathing

• blue lips

• refusal of food

In people over 65, pneumonia can quickly lead to respiratory failure. This age group is at the highest risk of hospitalization.

Pneumonia Diagnosis: What Tests Are Needed?

Timely diagnosis allows you to distinguish pneumonia from bronchitis or acute respiratory viral infections.

Main methods:

• doctor's examination and auscultation

• chest x-ray

• complete blood count

• C-reactive protein

• procalcitonin

• oxygen saturation determination

According to recommendations Mayo Clinic, radiography is the key method for confirming the diagnosis.

In difficult cases, a computed tomography of the lungs is performed.

Laboratory markers for pneumonia

A comprehensive assessment of the results helps determine the severity of the course.

Pneumonia treatment

Treatment depends on the type of pathogen.

For bacterial pneumonia:

• antibiotics are prescribed

• temperature controlled

• anti-inflammatory therapy is used

For viral pneumonia:

• antiviral drugs (as indicated)

• symptomatic treatment

• saturation monitoring

According to the position FDA, antibiotics are not used without a confirmed bacterial nature of the disease.

Hospitalization is necessary for:

• saturation below 94%

• severe shortness of breath

• concomitant chronic diseases

• old age

Possible complications of pneumonia

Pneumonia without proper treatment can lead to:

• pleurisy

• lung abscess

• sepsis

• respiratory failure

• exacerbation of cardiovascular diseases

That is why self-medication when pneumonia is suspected is dangerous.

Pneumonia prevention

Effective prevention includes:

• flu vaccination

• vaccination against pneumococcus

• quitting smoking

• chronic disease control

• regular medical checkups

It is especially important to undergo preventive examinations. people over 60 years old.

Pneumonia is a serious illness that can progress very quickly. If symptoms appear, it is important to see a doctor, undergo the necessary diagnostics, and begin treatment. Early medical care significantly reduces the risk of complications and helps restore health faster.
