Pneumonia - Symptoms, Causes & Treatment
Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm, fever, chills, and difficulty breathing.
Overview
Pneumonia is a leading cause of death from infectious disease worldwide. In India, it is particularly dangerous for children under 5 and adults over 65.
Pneumonia can be caused by bacteria, viruses, or fungi. The severity ranges from mild to life-threatening. Vaccination and early treatment significantly reduce complications.
Symptoms of Pneumonia
- FeverPrimary
Fever is a temporary increase in body temperature, usually above 100.4°F (38°C). It is a sign that the body is fighting an infection or illness.
- CoughPrimary
A cough is a reflex action to clear the airways of mucus, irritants, and foreign particles. It can be acute (lasting less than 3 weeks) or chronic (lasting more than 8 weeks).
- Shortness of BreathPrimary
Shortness of breath (dyspnea) is a feeling of not being able to get enough air, or difficulty breathing. It can be caused by various heart, lung, or other conditions.
- Chest Pain
Chest pain is any discomfort or pain felt in the area between the neck and upper abdomen. It can have many causes, ranging from minor issues to serious, life-threatening conditions.
- Fatigue
Fatigue is a feeling of persistent tiredness or exhaustion that does not improve with rest. It can be physical, mental, or both, and may indicate an underlying health condition.
- Night Sweats
Night sweats are repeated episodes of excessive sweating during sleep, severe enough to soak nightclothes and bedding, not related to an overheated sleeping environment.
Causes of Pneumonia
Bacterial infection (Streptococcus pneumoniae most common)
Viral infections (influenza, RSV, COVID-19)
Fungal infections
Aspiration of food, liquid, or vomit
Hospital-acquired infections
Weakened immune system
Treatment for Pneumonia
Antibiotics for bacterial pneumonia
Antiviral medications for viral pneumonia
Antifungal medications for fungal pneumonia
Rest and adequate fluid intake
Fever-reducing medications
Oxygen therapy for severe cases
Hospitalization for severe pneumonia
Mechanical ventilation if needed
Prevention
Get vaccinated (pneumococcal and flu vaccines)
Practice good hand hygiene
Quit smoking
Maintain a strong immune system
Avoid close contact with sick people
Practice good oral hygiene
Get adequate rest and nutrition
Risk Factors
Age under 5 or over 65
Chronic lung disease (COPD, asthma)
Weakened immune system
Smoking
Hospitalization (especially ICU)
Difficulty swallowing
Recent cold or flu
Chronic conditions (diabetes, heart disease)
When to See a Doctor
See a doctor if you have persistent fever, cough with phlegm, difficulty breathing, or chest pain when breathing. Seek emergency care for severe breathing difficulty, bluish lips or fingernails, confusion, or high fever that does not respond to treatment.

Which Doctor to Consult for Pneumonia

Related Conditions
These conditions share similar symptoms with pneumonia and may be relevant:
Tuberculosis
Tuberculosis (TB) is a potentially serious bacterial infection caused by Mycobacterium tuberculosis that mainly affects the lungs but can affect other parts of the body.
Coronary Artery Disease
Coronary artery disease (CAD) is the most common type of heart disease, caused by plaque buildup in the walls of arteries that supply blood to the heart.
Hypertension
Hypertension (high blood pressure) is a common condition where the force of blood against artery walls is consistently too high, increasing the risk of heart disease, stroke, and other health problems.
Asthma
Asthma is a chronic respiratory condition that causes inflammation and narrowing of the airways, leading to breathing difficulty, wheezing, coughing, and chest tightness.
Anemia
Anemia is a condition where the blood lacks enough healthy red blood cells or hemoglobin to carry adequate oxygen to the body's tissues, causing fatigue, weakness, and other symptoms.
GERD
Gastroesophageal Reflux Disease (GERD) is a chronic digestive condition where stomach acid frequently flows back into the esophagus, causing heartburn and irritation.
FAQS
Pneumonia FAQs
Common questions about pneumonia.
With proper treatment, mild pneumonia symptoms usually improve within 1-2 weeks. However, fatigue and cough may persist for a month or more. Severe pneumonia may require longer recovery time.
Bacterial and viral pneumonia can be spread through respiratory droplets from coughing or sneezing. However, not everyone exposed will develop pneumonia — it depends on their immune system and other risk factors.
