Pneumonia: diagnosis and treatment

In medical terms, this is an acute infection of the lower respiratory tract in which the alveoli, the microscopic sacs at the end of the bronchial tree, become packed with inflammatory exudate. Once these spaces are flooded, oxygen can no longer pass efficiently into the blood and carbon dioxide is not removed as it should be, so the body gradually runs short of the oxygen it needs.

Inflammation may stay confined to a single segment of the lung or spread across several lobes on one or both sides of the chest. Some people recover at home within two weeks, whereas others need intensive monitoring, and infants, seniors and anyone whose immune defenses are compromised can deteriorate within hours, so an early visit to a doctor is far safer than waiting it out.

Main types of pneumonia

Clinicians group the disease by the setting in which the infection was caught, the microorganism responsible and the pattern it leaves on imaging. When specialists talk about the types of pneumonia, they usually refer to the following categories, each with its own typical patient profile:

• community-acquired infection picked up during everyday life at home or work
• hospital-acquired infection appearing at least 48 hours after admission
• aspiration-related inflammation following the inhalation of food or gastric contents
• atypical forms caused by mycoplasma, chlamydia or legionella bacteria

Knowing which category applies helps the doctor choose the right tests and medicines from the very first appointment, instead of adjusting the therapy later by trial and error.

Causes and risk factors of pneumonia

Among the causes of pneumonia, microorganisms clearly dominate, although fungi, toxic fumes and accidentally inhaled material can also injure the alveolar walls. The pneumococcus is still the bacterium most often isolated in adults, whereas influenza and the respiratory syncytial virus are typical culprits in toddlers and the elderly. The chance of falling ill rises noticeably in people with:

• asthma, bronchiectasis or chronic obstructive pulmonary disease
• reduced immunity after chemotherapy, transplantation or prolonged steroid use
• a long history of cigarette smoking or regular passive exposure to smoke
• age below two years or above sixty-five, when natural defenses are weaker

Being aware of these factors makes it easier to plan vaccinations, quit harmful habits and seek medical advice sooner when a chest cold appears.

Symptoms and clinical course of pneumonia

The symptoms of pneumonia frequently start with a sore throat and runny nose that resemble a common cold, but within one or two days the condition becomes considerably heavier. Depending on the pathogen and the general condition of the patient, the complaints usually include:

• a stubborn cough bringing up yellow, green or rust-colored sputum
• fever above 38 degrees with shivering and night sweats
• stabbing chest pain that gets worse on inhaling or coughing
• rapid, shallow breathing and breathlessness during minor effort
• marked tiredness, drowsiness and a complete lack of appetite

Similar complaints accompany bronchitis, influenza and even heart failure, so only a professional examination can reliably separate these conditions and detect any complications at an early stage.

Bacterial pneumonia in adults

When bacteria are responsible, the illness in grown-ups usually announces itself abruptly, often within a single afternoon, with a temperature climbing towards 40 degrees, violent chills and a wet cough producing purulent sputum. Many patients also notice pleuritic pain on one side of the chest, a racing pulse and profound weakness. Fortunately, most bacteria respond well to correctly selected antibiotics, so starting therapy early limits the spread of inflammation and shortens recovery.

Viral pneumonia

This form typically creeps in slowly, often as a continuation of a seasonal flu or a cold that refuses to clear up. The cough generally remains dry and irritating, while headaches, aching muscles and persistent exhaustion accompany a moderate fever. Most otherwise healthy people get better with rest and symptomatic treatment, yet some viruses, including influenza and SARS-CoV-2, can trigger severe lung damage in high-risk groups, which is why careful observation matters.

Chemical and aspiration pneumonia

Lung injury of a chemical nature appears after breathing in chlorine, ammonia, dense smoke or other aggressive vapors, without any bacteria or viruses involved. Aspiration, in turn, happens when saliva, food or acidic stomach contents slip into the trachea instead of traveling down the esophagus, which is common after a stroke or in patients with impaired swallowing. In both situations, a doctor should assess the patient quickly, because damaged tissue is easily colonized by bacteria.

Diagnosing pneumonia

Knowing how to recognise pneumonia requires more than listening to a description of the complaints, since an accurate diagnosis combines a thorough physical examination with appropriate tests. While auscultating the chest, the doctor searches for crackles, bronchial breathing or areas where air movement is reduced, and also asks about recent infections, travel and medication. To confirm the disease and establish its origin, the following investigations are commonly ordered:

• a chest radiograph or computed tomography showing infiltrates in the lungs
• blood count together with C-reactive protein and procalcitonin levels
• pulse oximetry indicating the oxygen saturation of arterial blood
• microbiological sputum testing that identifies the pathogen and its drug sensitivity

Interpreting these results together lets the doctor decide whether outpatient care is sufficient and which medicines will work best in the particular case.

Treatment approaches for pneumonia

The treatment of pneumonia is chosen according to the suspected microorganism, the age of the patient and any coexisting chronic illnesses that may affect recovery. Bacterial infections require antibiotics selected on the basis of the probable pathogen and current resistance data, whereas viral cases are managed mainly with plenty of fluids, antipyretics, rest and, in selected situations, antiviral drugs.

When blood oxygen levels drop or the patient becomes exhausted, supplemental oxygen and admission to a hospital ward may be required to protect vital organs. At Lekarze w Warszawie, each therapy is planned individually, and the doctor reviews the dose, the choice of medicine and the timing of check-ups as the patient's condition changes.

Frequently asked questions 

Possible complications after pneumonia

The risk of complications after pneumonia depends mainly on how quickly therapy began and on the general fitness of the patient before falling ill. Fluid can collect in the pleural cavity and press on the lung, and in severe infections a pus-filled cavity known as a lung abscess may form. Reduced stamina during exercise frequently persists for weeks after the fever subsides, although prompt therapy and a follow-up appointment make lasting problems far less probable.

Is pneumonia contagious?

Whether pneumonia is contagious is determined by its origin: germ-related forms spread from one person to another, while lung damage caused by chemicals or aspiration poses no such threat. Pathogens leave the airways of a sick person in tiny airborne particles produced while speaking or clearing the throat, and some of them stay viable for hours on keyboards, handrails, cutlery and similar objects.

Washing hands with soap, using a tissue or an elbow to shield a cough and keeping some distance from relatives in the early phase of the disease make transmission much less likely. Older family members, expectant mothers and those receiving immunosuppressive drugs ought to be particularly cautious while a sick person shares their home.

How long does pneumonia last?

How long pneumonia lasts is highly individual, yet a mild case treated properly tends to ease within one or two weeks of starting medication. Low stamina and an occasional cough may linger well beyond that point, even though fever and chest discomfort have long gone. Anyone discharged from a ward should expect a recovery period of a month or longer, which is why finishing every prescribed dose and returning for a control visit matters so much.

How to prevent pneumonia

Figuring out how to prevent pneumonia starts with lowering everyday exposure to germs and pollutants that harm the airways. For youngsters and grown-ups alike, the most reliable protection comes from:

• yearly flu shots combined with a pneumococcal vaccine where advised
• careful hand hygiene and fewer visits to packed venues in autumn and winter
• quitting cigarettes and keeping living spaces free of smoke and dust
• stable control of diabetes, asthma and cardiovascular conditions

Combined with routine visits to a family physician, these straightforward habits help the lungs stay resilient for years to come.
