Preparing for bronchoscopy

Overview

Bronchoscopy is a procedure that lets a doctor look inside your airways — the tubes that carry air to and from your lungs. A thin, flexible tube with a tiny camera (called a bronchoscope) is gently passed through your nose or mouth. This test helps find the cause of breathing problems, take small tissue samples (biopsy), or remove blockages.

Yes, bronchoscopy is a common procedure performed in hospitals and clinics around the world.

It is used for people of all ages who have certain lung symptoms or conditions, such as a long-lasting cough, coughing up blood, or a suspicious spot on a chest X-ray.

Symptoms

Common symptoms

• Persistent cough that does not go away
• Coughing up blood or blood-streaked sputum
• Shortness of breath that is getting worse
• Repeated lung infections or pneumonia
• Chest pain or tightness

Symptoms in children

• Wheezing that doesn't improve with usual treatment
• Frequent or severe pneumonia
• Noisy breathing (stridor)
• Difficulty feeding because of breathing problems

Symptoms in older adults

• Same as common symptoms, plus unexplained weight loss or fatigue
• Worsening chronic bronchitis or emphysema
• Need to investigate possible lung cancer or other age-related lung conditions

Causes

Main causes

• Lung infections that are hard to diagnose, like tuberculosis or fungal infections
• Lung cancer or suspicious spots seen on an X-ray or CT scan
• A long-lasting cough with no clear cause
• Inhaled foreign objects (especially common in children)
• Bleeding in the airways

Risk factors

• Smoking or vaping
• Exposure to lung irritants like asbestos, dust, or chemicals
• Long-term lung diseases such as COPD, asthma, or bronchiectasis
• A weakened immune system from illness or medication

When to see a doctor

See a doctor urgently if:

• Coughing up blood (even a small amount)
• Sudden worsening of your breathing
• Chest pain that comes with coughing or deep breathing

Book a routine appointment if:

• A cough that lasts more than three weeks
• Unexplained weight loss along with a cough
• Repeated episodes of pneumonia

Diagnosis

Bronchoscopy is used to diagnose lung problems. Before the procedure, you usually have a physical exam and imaging tests to see what is going on inside your chest.

Tests that may be done

• Chest X-ray
• CT scan of the chest (a detailed 3D picture)
• Blood tests to check for infection or other issues
• Breathing tests (pulmonary function tests)

What to expect at your appointment

Before the procedure, you will be asked not to eat or drink for 6 to 8 hours. You will receive a sedative through a needle in your arm to help you relax. The doctor will spray a numbing medicine into your nose or throat. Then the bronchoscope is gently passed into your airways. You may feel some pressure or coughing, but it is not painful. The procedure takes about 30 to 60 minutes. Afterwards, you will rest in a recovery area for a few hours until the sedation wears off. Your throat may be sore, and you might cough up a little blood. You must have someone drive you home.

Treatment

Bronchoscopy can be both a diagnostic and a treatment tool. For example, the doctor may remove a foreign object that was inhaled, take out a small growth, or place a small tube (stent) to keep an airway open.

Self-care at home

• Follow your doctor's instructions about not eating or drinking before the procedure
• Arrange for a ride home – you cannot drive yourself after sedation
• Avoid smoking for at least 24 hours before and after the procedure
• Tell your doctor about all medicines you take, especially any that stop blood from clotting (like warfarin or aspirin)

Medical treatments

If a biopsy is taken during bronchoscopy, the tiny tissue sample is sent to a lab for testing. Depending on the results, your doctor may recommend further treatment such as antibiotics for an infection, medicines to reduce inflammation (like steroids), or other therapies to treat the underlying condition. Your healthcare team will discuss the results and next steps with you in detail.

When is surgery considered?

If a condition found during bronchoscopy requires a more involved operation (for example, to remove a part of the lung), your doctor will explain all the surgical options and help you prepare.

Living with this condition

Most people feel back to normal within a day or two after bronchoscopy. You may have a mild sore throat or a slight cough for a few days. For the first 24 hours, avoid driving, using machinery, making important decisions, or drinking alcohol.

Lifestyle tips

• Do not smoke or vape for at least 24 hours after the procedure and ideally try to quit for good
• Rest for the remainder of the day after your bronchoscopy
• Drink warm fluids (like tea or soup) to soothe your throat

Diet and exercise

You can eat normally once the numbing medicine wears off, usually within a couple of hours. Soft, cool foods like yogurt or smoothies may be easier if your throat is sore. Gentle activity like walking is fine, but avoid strenuous exercise for 24 hours.

Mental health and emotional wellbeing

Waiting for biopsy results or answers about your lungs can be very stressful. It is normal to feel anxious or worried before and after a bronchoscopy. Talk to your doctor or a counselor about your feelings. If you feel overwhelmed or have thoughts of harming yourself, reach out to a crisis support service immediately.

Prevention

Bronchoscopy itself is not something you prevent – it is a helpful procedure. However, you can reduce your chance of having a lung problem that might lead to a bronchoscopy by not smoking, avoiding lung irritants, and treating infections early.

Vaccines

Yes, staying up to date with recommended vaccinations – such as the flu vaccine and pneumonia vaccine – can lower your risk of lung infections that could require a bronchoscopy.

Screening programmes

If you are at high risk for lung cancer (heavy smoker, family history), your doctor may suggest a low-dose CT scan screening. This can find lung problems early, sometimes before a bronchoscopy is needed.

Complications

If left untreated

• If a condition found during bronchoscopy (like an infection or tumour) is not treated, it could get worse – for example, an infection may spread or a tumour may grow larger.
• Untreated airway blockages can lead to collapsed lung (atelectasis) or more severe breathing problems.
• Following your doctor's plan after the procedure is very important for the best outcome.

Long-term outlook

Bronchoscopy is a safe and valuable procedure. The outlook depends on what is found and how it is treated. Many conditions discovered by bronchoscopy are treatable, and your healthcare team will work with you to create a plan that gives you the best chance of recovery. Even if something serious is found, early diagnosis through bronchoscopy can lead to better treatment options and hope.
