pneumonia flare ups

Overview

Pneumonia is an infection in your lungs where the tiny air sacs fill with fluid or mucus, making it harder to breathe. A pneumonia flare-up means a sudden return or worsening of pneumonia symptoms, often in someone who has had pneumonia before or has a long-term lung condition.

Yes. Pneumonia is a common infection worldwide, and flare-ups are especially common in people with long-term lung conditions such as COPD or asthma, and in older adults.

Anyone can get pneumonia, but flare-ups are more likely in young children, older adults, people who smoke, and those with chronic health conditions like asthma, diabetes, or heart disease. People with weakened immune systems are also at higher risk.

Symptoms

Common symptoms

• Cough that may bring up mucus
• Fever, sweats, and chills
• Shortness of breath or fast breathing
• Chest pain when breathing deeply or coughing
• Fatigue and muscle aches
• Loss of appetite or feeling generally unwell

Symptoms in children

• Fast or noisy breathing
• Flaring of the nostrils or grunting while breathing
• Poor feeding or unusual sleepiness
• High temperature and cough
• Irritability or crying more than usual

Symptoms in older adults

• Confusion or changes in mental state
• Low body temperature instead of fever
• Weakness and loss of energy
• Difficulty breathing or rapid breathing
• A cough that may be dry or have little mucus – sometimes no cough at all

Causes

Main causes

• Bacterial infections – the most common cause in adults
• Viral infections, such as influenza or cold viruses
• Fungal infections – more common in people with weakened immune systems or in certain geographic areas
• Aspiration – breathing in food, liquid, or saliva into the lungs

Risk factors

• Age – being very young or over 65
• Smoking or heavy alcohol use
• Chronic lung disease (such as COPD, asthma, or cystic fibrosis)
• Weakened immune system from illness or medicines
• Being in hospital or a long-term care facility
• Heart disease, diabetes, or other health conditions

When to see a doctor

See a doctor urgently if:

• If you have difficulty breathing or chest pain
• If you cough up blood
• If your fever is very high or lasts more than 48 hours
• If you feel confused or very weak

Book a routine appointment if:

• If you have a new cough with fever that lasts more than a few days
• If you have a chronic condition and your breathing is getting worse
• If you have recovered from pneumonia and symptoms return

Diagnosis

A doctor will listen to your lungs, ask about your symptoms and health history, and may order tests to check for the cause and severity of the infection.

Tests that may be done

• Chest X-ray – to see if there is infection in the lungs
• Blood tests – to check for signs of infection and oxygen levels
• Oxygen saturation test – a small clip on your finger to measure oxygen
• Sputum (mucus) sample – to find the germ causing the infection
• Breathing tests – if you have a long-term lung condition

What to expect at your appointment

Your doctor may check your temperature, breathing rate, oxygen level, and listen for crackling sounds. You may be asked to have a chest X-ray and blood tests. Most people can go home the same day. If you are sent home, you will be given a recovery plan and told when to seek help again.

Treatment

Treatment depends on the cause – viral or bacterial – and on your overall health and how severe the flare-up is. For bacterial infections, doctors commonly prescribe antibiotics. For viral infections, rest and fluids are the main treatment. Some people need extra oxygen or hospital care.

Self-care at home

• Rest as much as you need
• Drink plenty of fluids to avoid dehydration
• Take simple pain relief for fever or discomfort – ask your pharmacist or doctor which is suitable
• Do not smoke or avoid second-hand smoke
• Use a cool-mist humidifier or take a warm bath to ease a cough

Medical treatments

Medical treatment may include antibiotic tablets or injections (if the cause is bacterial), antiviral medicines for certain viruses, oxygen therapy if oxygen levels are low, and intravenous fluids in hospital. Always complete the full course of any medicine your doctor prescribes, even if you feel better.

When is surgery considered?

Surgery is rarely needed for pneumonia. It may be considered if a collection of infected fluid (empyema) or a lung abscess develops. Your doctor will discuss this if it is relevant to your case.

Living with this condition

During a flare-up, focus on rest and recovery. Plan easy activities, take your medicines as prescribed, and contact your doctor if you are not improving. Using a symptom diary can help you notice changes early.

Lifestyle tips

• Quit smoking or ask for help to quit
• Avoid close contact with people who have colds or flu
• Wash your hands regularly
• Keep up with your regular medicines for chronic conditions
• Catch up on sleep and manage stress

Diet and exercise

Eating a balanced diet with plenty of fruits and vegetables helps your body fight infection. Gentle movement, like short walks, can help you regain strength after a flare-up – but wait until your doctor says it is safe. Avoid heavy exercise until you feel fully recovered.

Mental health and emotional wellbeing

Being ill can feel frustrating and lonely. It is normal to feel anxious or low while recovering. Talk to friends or family about how you are feeling, and let your care team know if you are struggling. If you have thoughts of self-harm, contact your local emergency service or crisis helpline immediately.

Prevention

Yes. Many pneumonia flare-ups can be prevented with vaccination, good hygiene, keeping chronic conditions well managed, and avoiding smoking. Cover your cough when you are sick and stay home to avoid spreading germs.

Vaccines

There are vaccines that can help prevent some causes of pneumonia, such as the flu vaccine and the pneumococcal vaccine. Ask your doctor, nurse, or pharmacist which vaccines are recommended for you and when to have them.

Screening programmes

There is no routine pneumonia screening. However, if you have repeated flare-ups, your doctor may recommend lung function tests to check for underlying problems.

Complications

If left untreated

• Spread of infection to the bloodstream (bacteremia)
• Fluid around the lungs (pleural effusion) that may need draining
• Lung abscess – a collection of pus in the lung tissue
• Severe breathing failure needing a ventilator

Long-term outlook

Most people with pneumonia recover completely, although it may take a few weeks to feel back to normal. With prompt treatment and good support, the risk of serious complications is low. Following your doctor’s advice and looking after your health can help prevent future flare-ups.
