pneumonia lifestyle tips for patients

Overview

Pneumonia is an infection of the lungs that causes tiny air sacs to fill with fluid or pus. It can make breathing difficult and cause coughing, fever, and chills. It can be caused by viruses, bacteria, or other germs.

Yes. Pneumonia is a common illness worldwide. In the UK, many people are treated in hospital for pneumonia each year, and many more recover at home.

Pneumonia can affect people of all ages. It is most serious in babies, older adults, smokers, and people with long-term health problems like asthma, heart disease, or diabetes.

Symptoms

Common symptoms

• Cough, which may bring up mucus
• Fever, sweating, and shaking chills
• Shortness of breath
• Chest pain when breathing or coughing
• Feeling very tired or weak
• Loss of appetite

Symptoms in children

• Fast or difficult breathing
• Cough and fever
• Trouble feeding or drinking
• Being unusually sleepy or irritable

Symptoms in older adults

• Confusion or change in mental awareness
• Low body temperature
• Cough or difficulty breathing that may be the only symptom
• Weakness and poor appetite

Causes

Main causes

• Viruses, such as the flu or respiratory syncytial virus (RSV)
• Bacteria, most commonly Streptococcus pneumoniae (a type of germ)
• Rarely, fungi or other germs, especially in people with weakened immune systems

Risk factors

• Age under 2 or over 65
• Smoking or exposure to secondhand smoke
• Long-term health conditions like asthma, COPD, diabetes, or heart disease
• A weakened immune system (for example, after an illness or certain treatments)
• Being in hospital or a care facility for a long time

When to see a doctor

See a doctor urgently if:

• Have trouble breathing
• Feel confused or very drowsy
• Cough up dark blood
• Have a very high fever that won't come down with rest
• Your symptoms get worse after days of feeling ill

Book a routine appointment if:

• You have a persistent cough with mucus
• You feel breathless with normal activities
• You have a fever or chills lasting more than a few days
• You are an older adult, a young child, or have a chronic illness and think you may have pneumonia

Diagnosis

A doctor will ask about your symptoms and listen to your lungs with a stethoscope. They may check your temperature, breathing rate, and oxygen levels. If they suspect pneumonia, they may arrange tests.

Tests that may be done

• Chest X-ray to see infection in the lungs
• Blood tests to look for signs of infection
• A mucus sample (phlegm) to identify the cause
• Pulse oximetry to check oxygen levels in your blood

What to expect at your appointment

Diagnosis is usually quick. You may be asked to breathe in deeply while the doctor listens. If tests are needed, staff will explain what they are and why. Many people can be diagnosed in one visit.

Treatment

Treatment depends on the cause (viral or bacterial), your age, and how severe the infection is. Many people recover at home, but some need hospital care for fluids, oxygen, or closer monitoring.

Self-care at home

• Get plenty of rest so your body can fight the infection
• Drink enough fluids to stay hydrated and keep mucus loose
• Rest with your head raised to help make breathing easier
• Follow your healthcare provider's advice about when to return for review

Medical treatments

Doctors may prescribe medicine to treat a bacterial infection, if that is the cause. They may also give medicines to reduce fever and discomfort. For more serious cases, hospital treatment might include oxygen or intravenous fluids. Always take medicines exactly as prescribed and finish the full course, even if you feel better.

When is surgery considered?

Surgery is rarely needed for pneumonia. It may be considered only for very unusual complications, such as an abscess (a pocket of infected fluid) in the lung. Your specialist will discuss any options with you.

Living with this condition

Give yourself time to heal. You may feel tired for weeks. Even after you feel better, your lungs take time to recover. Go back to your normal routine slowly and listen to your body.

Lifestyle tips

• Don't smoke and avoid secondhand smoke — it makes recovery harder
• Avoid crowded or dusty places while your lungs are healing
• Wash your hands often to avoid catching other infections
• Keep follow-up appointments with your doctor
• Rest whenever you feel tired

Diet and exercise

Eat small, nutritious meals and include protein-rich foods like eggs, beans, or lentils to help repair tissue. Drink plenty of fluids like water, warm soups, or herbal tea. Gentle activity, like short walks, can help your circulation, but wait until your doctor says it's safe.

Mental health and emotional wellbeing

Recovering from pneumonia can be a slow process and it is normal to feel frustrated or low. If you feel anxious or depressed, talk to your healthcare team. They can support you and connect you with helpful services.

Prevention

Many cases of pneumonia can be prevented. Good hygiene, avoiding smoking, and staying healthy overall reduce your risk. Vaccines are also available for some of the most common causes.

Vaccines

Vaccines for flu, COVID-19, and pneumococcal infection (a type of bacterial pneumonia) can lower your chances of getting pneumonia. Ask your doctor or local health service which vaccines are recommended for you.

Screening programmes

There is no routine screening test for pneumonia, but regular check-ups and vaccinations help people at high risk stay protected.

Complications

If left untreated

• Breathing failure that requires oxygen or a breathing machine
• The infection spreading into the blood or other parts of the body
• A fluid collection around the lungs (effusion) that may need draining
• Long-term tiredness or reduced lung function

Long-term outlook

Most people with pneumonia recover fully, especially with timely treatment and good rest. It may take weeks to feel completely back to normal, but the outlook is positive. Following your doctor's advice and taking care of yourself make a big difference.
