What is pneumonia?

Pneumonia is an infection that causes inflammation of the air sacs (alveoli) in one or both lungs. The air sacs may fill with fluid or pus, leading to symptoms such as a cough with phlegm, fever, chills, and difficulty breathing. According to the NHS, pneumonia can range from mild to life-threatening and is most serious in infants, young children, older adults, and people with weakened immune systems or underlying health conditions.

Pneumonia can be caused by a variety of organisms, including bacteria, viruses, and — less commonly — fungi. Bacterial pneumonia, most often caused by Streptococcus pneumoniae, is one of the most common forms in the UK. Viral pneumonia may result from influenza, respiratory syncytial virus (RSV), or SARS-CoV-2 (the virus responsible for COVID-19). The type of organism involved influences the severity of the infection and the approach to treatment. Community-acquired pneumonia (CAP) — pneumonia contracted outside of a hospital setting — is particularly common and accounts for the majority of cases seen in general practice. Hospital-acquired pneumonia (HAP) develops during or shortly after a hospital stay and tends to be more severe due to exposure to more resistant organisms. Aspiration pneumonia occurs when food, liquid, or vomit is inhaled into the lungs, which is more common in individuals with swallowing difficulties or reduced consciousness.

How is pneumonia diagnosed?

Diagnosing pneumonia typically begins with a thorough clinical assessment. Your doctor will ask about your symptoms, their onset and duration, and any relevant medical history. A physical examination will include listening to your chest with a stethoscope for characteristic sounds such as crackles or reduced breath sounds, which may suggest fluid or inflammation within the lungs. Vital signs — including temperature, heart rate, respiratory rate, and oxygen saturation — are also evaluated to gauge the severity of the infection.

Further investigations may be required to confirm the diagnosis and identify the causative organism. A chest X-ray is the most commonly used imaging tool and can reveal areas of consolidation consistent with pneumonia. Blood tests such as a full blood count, C-reactive protein (CRP), and blood cultures may help determine whether the infection is bacterial and how the body is responding. In some cases, sputum samples are collected for culture and sensitivity testing, which guides antibiotic selection. According to NICE guidelines (NG138) on pneumonia in adults, the CRB-65 severity scoring system is used in primary care to assess the risk of complications and determine whether hospital admission is needed. This score considers confusion, respiratory rate, blood pressure, and age (65 or over). At Spital Clinic, our GPs use evidence-based tools to ensure an accurate diagnosis and appropriate management plan for every patient.

How is pneumonia treated?

Treatment for pneumonia depends on the type, severity, and the individual’s overall health. Mild cases of community-acquired pneumonia can often be managed at home with a course of oral antibiotics, rest, and plenty of fluids. In line with NICE guidelines, the antibiotic choice depends on the severity score and local resistance patterns, but amoxicillin is commonly prescribed as first-line treatment for low-severity community-acquired pneumonia. It is crucial to complete the full course of antibiotics as prescribed, even if symptoms begin to improve within a few days.

For viral pneumonia, antibiotics are not effective against the underlying virus. Treatment is largely supportive — including rest, fluids, and paracetamol or ibuprofen for fever and pain relief. In cases caused by influenza, antiviral medications such as oseltamivir may be considered if started within 48 hours of symptom onset. More severe cases of pneumonia may require hospital admission for intravenous antibiotics, supplemental oxygen, and, in the most critical situations, ventilatory support in an intensive care unit. NICE recommends reassessing patients who do not improve within 48 hours of starting antibiotics, as a change in treatment or further investigation may be needed. Recovery from pneumonia can take time — while most people start to feel better within a week, fatigue and a lingering cough can persist for several weeks. Follow-up with your GP is important to ensure complete resolution and to identify any complications early.

What are the risk factors for pneumonia?

While anyone can develop pneumonia, certain factors significantly increase the risk. Age is one of the most important — infants and young children under 2 years of age and adults over 65 are at considerably higher risk. Chronic lung diseases such as COPD, asthma, and bronchiectasis also increase susceptibility, as do other long-term conditions including diabetes, heart disease, kidney disease, and liver disease. Smoking damages the lungs' natural defence mechanisms and is a well-established risk factor. Excessive alcohol consumption can impair the immune response and the cough reflex, making aspiration pneumonia more likely. Individuals who are immunocompromised — whether due to HIV, chemotherapy, long-term steroid use, or organ transplantation — are particularly vulnerable. Other risk factors include recent viral respiratory infections such as influenza or COVID-19, which can predispose the lungs to secondary bacterial infection. Being aware of your personal risk factors can help you take preventative steps and seek early treatment should symptoms arise.

how does pneumonia affect your daily life?

Pneumonia can have a significant impact on daily life, particularly during the acute phase of illness. Symptoms such as breathlessness, fatigue, persistent cough, and chest pain can make it difficult to carry out routine activities, attend work, or care for dependents. Even after the acute infection has resolved, many people experience a prolonged recovery period. The British Thoracic Society notes that it may take six weeks or longer before energy levels return to normal. The psychological impact of pneumonia should not be underestimated. A serious bout of pneumonia, especially one requiring hospitalisation, can lead to anxiety about recurrence, low mood, and reduced confidence in physical abilities. Returning to normal activities should be gradual, guided by how you feel, and in consultation with your GP. Post-pneumonia follow-up — typically at six weeks — is recommended to ensure the infection has fully cleared, often with a repeat chest X-ray, particularly for those over 50 or with persistent symptoms.
