pneumonia complications awareness

Overview

Pneumonia is an infection in one or both lungs. The small air sacs inside the lungs fill with fluid or phlegm, which can make it harder to breathe. Complications are extra health problems that can happen because of a severe or untreated pneumonia.

Yes. Pneumonia is a common illness worldwide. Millions of people get it each year, and most recover fully.

Pneumonia can happen at any age. However, it is more common and more serious in babies, young children, adults over 65, and people with weakened immune systems, asthma, diabetes, or heart disease.

Symptoms

Common symptoms

• A cough that may bring up phlegm
• Fever or chills
• Fast or difficult breathing
• Chest pain when breathing or coughing
• Extreme tiredness or weakness

Symptoms in children

• Rapid breathing or breathlessness
• Flaring of the nostrils
• A grunting sound when breathing
• Poor feeding or drinking less than usual
• Very high temperature

Symptoms in older adults

• Confusion or changes in mental awareness
• Dizziness or unsteadiness
• A lower temperature than normal, rather than a fever
• Unexplained falls or being less active

Causes

Main causes

• Bacteria (the most common cause of bacterial pneumonia)
• Viruses, including the cold and flu viruses
• Fungi, especially for people with weakened immune systems

Risk factors

• Age under 2 or over 65
• Smoking or exposure to tobacco smoke
• Long-term health conditions such as asthma, diabetes, or heart disease
• A weakened immune system from illness or certain treatments
• Recently having a cold or flu

When to see a doctor

See a doctor urgently if:

• Your breathing is getting harder
• You have a very high temperature that will not settle
• You feel very dizzy, or you are showing signs of confusion
• Your cough is getting worse or you are coughing up blood

Book a routine appointment if:

• You have had a cough for more than three weeks
• You are not getting better after a few days
• You are losing weight without trying
• You feel generally unwell and are anxious about your symptoms

Diagnosis

A doctor will ask about your symptoms, listen to your chest with a stethoscope, and may check the amount of oxygen in your blood. Based on this, they may suggest further tests.

Tests that may be done

• Chest X-ray to look at the lungs
• Blood tests to check for infection and organ function
• Pulse oximetry to measure oxygen levels
• Sputum (phlegm) test to identify the cause
• A urine test for certain bacteria if needed

What to expect at your appointment

You will usually have a physical exam and some simple tests. Some results come back quickly, while cultures from sputum or blood can take a few days. Your doctor will explain the findings and agree a treatment plan with you.

Treatment

Treatment depends on what is causing the pneumonia, how severe it is, and your general health. If it is mild, you may only need rest and home care. More severe cases may require hospital treatment.

Self-care at home

• Get plenty of rest
• Drink enough fluids to stay hydrated
• Use a humidifier or sit in a steamy bathroom to ease coughing
• Take simple fever and pain relief as advised by your pharmacist or doctor
• Avoid smoke and other lung irritants

Medical treatments

For bacterial pneumonia, a course of antibiotics is usually prescribed. Viral pneumonia may be treated with antiviral medication in some cases, although many viral infections just need supportive care. If oxygen levels are low, oxygen therapy is given, and some people need to be admitted to hospital for closer monitoring or intravenous fluids and medication.

When is surgery considered?

Surgery is rarely needed for pneumonia. In exceptional cases, a collection of infected fluid around the lungs (an empyema) may need to be drained. Your specialist will discuss this with you if it applies.

Living with this condition

Recovery takes time. You may feel tired for several weeks after leaving hospital or finishing antibiotics. Go at your own pace, and build up your activity gradually.

Lifestyle tips

• Do not smoke and avoid secondhand smoke
• Wash your hands regularly
• Cover your mouth when coughing or sneezing
• Keep warm and avoid close contact with people who have infections

Diet and exercise

Eat a balanced diet with plenty of fruit and vegetables to help your immune system. Gentle activities such as short walks can help your lungs recover, but avoid heavy exercise until you feel stronger.

Mental health and emotional wellbeing

Feeling low or anxious while recovering from a serious illness is normal. It can help to share your feelings with someone you trust, and to focus on small, positive steps each day.

Prevention

You can reduce your risk of pneumonia by staying healthy and keeping up to date with recommended vaccines. Good hygiene and not smoking also make a big difference.

Vaccines

Ask your healthcare provider about protecting yourself against pneumonia and flu. Vaccines are available for some causes of pneumonia, and the flu vaccine can help stop a common trigger. Your local health service can advise which vaccines are right for you.

Screening programmes

There is no routine screening test for pneumonia in healthy people. If you have a long-term condition, your doctor may check your lungs more regularly and recommend a yearly flu jab.

Complications

If left untreated

• Sepsis (a severe, life-threatening reaction to infection)
• Lung abscess (a pocket of pus inside the lung)
• Pleural effusion (fluid around the lungs)
• Respiratory failure (when the lungs cannot get enough oxygen into the blood)

Long-term outlook

Most people with pneumonia make a complete recovery with appropriate care. Even when complications occur, early treatment greatly improves the outcome. Following your treatment plan and attending follow-up appointments gives you the best chances of getting back to full health. Keep in touch with your healthcare team if you have concerns – they are there to help you.
