What is Pneumonia?
Pneumonia is an infection of the lungs that causes inflammation in the air sacs (alveoli). These sacs can fill with fluid or pus, making it harder to breathe and reducing oxygen supply to the body. Pneumonia can range from mild to life-threatening.
It affects all age groups but is more serious in older adults, young children, and people with chronic medical conditions. Prompt diagnosis and treatment are important to prevent complications.
What Causes Pneumonia?
Infections
- Bacterial pneumonia – the most common type in adults; often caused by Streptococcus pneumoniae
- Viral pneumonia – caused by viruses such as influenza or COVID-19
- Fungal pneumonia – rare, usually in immunocompromised individuals
Risk Factors and Lifestyle
- Chronic lung conditions (asthma, COPD)
- Smoking or exposure to second-hand smoke
- Weak immune system
- Recent viral infections (cold, flu)
- Age: very young or elderly individuals
What Are the Common Symptoms of Pneumonia?
- Cough, often producing yellow, green, or blood-streaked mucus
- Fever, sometimes high
- Shortness of breath or rapid breathing
- Chest pain, especially when breathing or coughing
- Fatigue and general malaise
- Chills or sweating
- Confusion, particularly in older adults
- Nausea, vomiting, or loss of appetite
How Is Pneumonia Diagnosed?
Diagnosis is based on symptoms, physical examination, and sometimes imaging or lab tests.
During an online GP consultation, we can:
- Review your symptoms and risk factors
- Advise whether urgent in-person assessment or hospital care is needed
- Recommend appropriate tests such as chest X-rays, blood tests, or sputum sample
- Provide prescriptions for antibiotics if bacterial pneumonia is suspected
You may need an in-person assessment if:
- Breathing difficulty is significant
- Oxygen levels are low
- High fever or rapid deterioration occurs
How Long Does Pneumonia Last?
- Mild bacterial or viral pneumonia usually improves within 1–3 weeks with treatment
- Cough and fatigue may persist for several weeks after recovery
- Severe pneumonia or pneumonia in vulnerable individuals can take longer to recover
Is Pneumonia Contagious?
- Pneumonia itself is not always contagious, but the viruses and bacteria that cause it can spread through coughs, sneezes, and close contact
- Good hygiene and vaccination reduce the risk of transmission
How to Feel Better and Recover Quickly
Self-Care at Home
- Rest and avoid strenuous activity
- Stay hydrated
- Use a humidifier or steam inhalation for breathing comfort
- Take paracetamol or ibuprofen for fever, aches, or discomfort
- Avoid smoking and smoky environments
- Monitor symptoms carefully, especially breathing
Treatment from a GP
A GP may:
- Prescribe antibiotics for bacterial pneumonia
- Recommend antiviral treatment if appropriate
- Advise inhalers or oxygen support for breathing difficulties
- Provide fit notes for work or study
- Offer guidance on monitoring recovery
When Referral Is Needed
Referral or hospital care may be needed if:
- Symptoms are severe or rapidly worsening
- Oxygen levels are low
- There is persistent high fever
- Complications such as pleural effusion or sepsis are suspected
