bronchitis procedure preparation

Overview

Bronchitis is when the tubes that carry air to your lungs (called bronchial tubes) become swollen and produce extra mucus. This causes coughing, sometimes with phlegm (thick mucus), and makes it harder to breathe. It is usually caused by a viral infection like a cold or flu.

Yes, bronchitis is very common. Most people will get acute bronchitis at some point, especially during cold and flu season.

Anyone can get acute bronchitis, but it is more common in children under five and in older adults. Chronic bronchitis is most often seen in people aged 40 and older who smoke or have been exposed to lung irritants for a long time.

Symptoms

Common symptoms

• Cough that brings up clear, white, yellow, or green mucus (phlegm)
• Shortness of breath or wheezing (a whistling sound when you breathe)
• Chest tightness or discomfort
• Fatigue and tiredness
• Low fever and chills
• Sore throat or runny nose (if it started as a cold)

Symptoms in children

• Cough (may be dry or with phlegm)
• Fast or noisy breathing
• Trouble feeding due to coughing or breathing difficulty
• Irritability and fussiness
• Fever (sometimes high)

Symptoms in older adults

• Confusion or drowsiness (sign of low oxygen)
• Weakness and loss of energy
• Increased confusion if they have dementia
• Worsening of existing breathing problems
• Cough may produce little phlegm

Causes

Main causes

• Viral infection – same viruses that cause the common cold or flu (most common cause)
• Bacterial infection – less common, but can happen after a viral infection
• Inhaling irritants – like cigarette smoke, air pollution, dust, or chemical fumes

Risk factors

• Smoking or being around second-hand smoke
• Having a weakened immune system (from illness, medicines, or age)
• Living in a place with high air pollution
• Working in jobs that expose you to dust, fumes, or strong chemicals (like mining or farming)
• Having asthma or other lung disease

When to see a doctor

See a doctor urgently if:

• Any of the emergency symptoms listed above – call your local emergency number right away.
• If you have a high fever (over 101°F / 38.3°C) that does not improve after 3 days.

Book a routine appointment if:

• If your cough lasts more than 3 weeks without getting better.
• If you have repeated bouts of bronchitis (more than 2 or 3 times a year).
• If you have a chronic medical condition like heart disease or COPD and get new breathing symptoms.

Diagnosis

Your doctor will usually diagnose bronchitis by asking about your symptoms and listening to your lungs with a stethoscope. They may ask about your medical history and whether you smoke. In most cases, no special tests are needed.

Tests that may be done

• Chest X-ray – to rule out pneumonia or other lung problems
• Pulse oximetry – a small clip on your finger to check oxygen levels in your blood
• Sputum culture – testing a sample of the mucus you cough up to see if bacteria are present
• Pulmonary function tests – simple breathing tests to see how well your lungs work (only if chronic bronchitis is suspected)
• Blood tests – sometimes done to look for signs of infection or inflammation

What to expect at your appointment

If you need a chest X-ray or a sputum test, your doctor will explain what will happen. For a sputum test, you will be asked to cough deeply to bring up mucus into a cup. These tests are usually quick and painless. Preparing for a bronchoscopy (a thin tube to look inside your lungs) is rare for simple bronchitis. If it is needed, your doctor will give you clear instructions, which may include stopping certain medicines or fasting for a few hours.

Treatment

Treatment depends on whether your bronchitis is acute (short-term) or chronic (long-term). Most acute bronchitis is caused by a virus, so antibiotics do not help. The goal is to relieve symptoms and let your body heal. Chronic bronchitis needs ongoing care to keep lungs working as well as possible.

Self-care at home

• Get plenty of rest to help your body fight the infection.
• Drink plenty of fluids (water, herbal tea) to thin mucus and make it easier to cough up.
• Use a humidifier or breathe in steam from a bowl of hot water (carefully) to ease a dry cough.
• Honey can soothe a cough for adults and children over age 1 (never give honey to babies under 1 year).
• Avoid smoke and other lung irritants.

Medical treatments

Your doctor may recommend medicines to help with symptoms – for example, a cough medicine or a pain reliever for fever and aches. Do not use over-the-counter cough and cold medicines in children under 6 unless a doctor says to. For chronic bronchitis, your doctor may prescribe inhalers to help open the airways or reduce swelling. In some cases, a short course of steroids (taken by mouth or inhaled) may be used to calm inflammation. Oxygen therapy may be needed if oxygen levels get too low. Always follow your doctor’s advice about any medicines.

When is surgery considered?

Surgery is not used to treat bronchitis. In very rare cases, if chronic bronchitis leads to a collapsed lung or other serious complication, a procedure might be needed, but this is extremely uncommon.

Living with this condition

If you have acute bronchitis, you may need to take it easy for a week or two. If you have chronic bronchitis, managing your daily activities is important. Pace yourself, avoid heavy exertion on bad days, and keep up with your regular medical visits.

Lifestyle tips

• If you smoke, quitting is the most important step you can take. Ask your doctor for support.
• Avoid lung irritants like second-hand smoke, strong fumes, and air pollution.
• Practice good hand hygiene to reduce your risk of catching colds and flu.
• Get recommended vaccines (like flu and pneumonia vaccines).

Diet and exercise

Eat a balanced diet with plenty of fruits, vegetables, and whole grains to support your immune system. Staying hydrated helps keep mucus thin. Gentle exercise – like walking – can help keep your lungs healthy, but stop if you feel breathless. Talk to your doctor about a safe exercise plan if you have chronic bronchitis.

Mental health and emotional wellbeing

Being sick for a long time or having trouble breathing can be scary and frustrating. You may feel anxious, stressed, or down. It is important to talk about these feelings with your doctor or a mental health professional. You are not alone – support groups and counselling can help.

Prevention

You cannot always prevent acute bronchitis, but you can lower your risk by washing hands often, staying away from sick people, and not smoking. Getting a yearly flu vaccine and the pneumonia vaccine (if recommended by your doctor) can help prevent infections that lead to bronchitis.

Vaccines

Yes – the flu vaccine and the pneumonia vaccine are recommended for many people, especially older adults, young children, and those with chronic health conditions. Ask your doctor which vaccines are right for you.

Screening programmes

There is no routine screening for bronchitis. If you have a chronic cough or are at risk for chronic bronchitis (for example, if you smoke), your doctor may recommend regular check-ups to monitor your lungs.

Complications

If left untreated

• Pneumonia – a serious lung infection that can develop from bronchitis, especially in older adults or people with weak immune systems.
• Worsening of chronic lung conditions like asthma or COPD.
• Respiratory failure – rare, but can happen if oxygen levels drop too low for too long.

Long-term outlook

For most people with acute bronchitis, the outlook is excellent. Symptoms usually clear up on their own within a few weeks. For chronic bronchitis, it is a long-term condition, but with good management – including quitting smoking, taking medicines as prescribed, and staying active – you can lead a full and active life. Work with your healthcare team to keep your lungs as healthy as possible.
