COPD screening test preparation

Overview

COPD (chronic obstructive pulmonary disease) is a long-term lung condition that makes it hard to breathe. It includes chronic bronchitis (long-term inflammation of the airways) and emphysema (damage to the air sacs in the lungs).

Yes, COPD is common, especially in people over 40 who have smoked or been exposed to lung irritants. It affects millions of people worldwide.

COPD mainly affects older adults, particularly those with a history of smoking. It can also affect people with long-term exposure to air pollution, chemical fumes, or dust at work. A rare genetic condition called alpha-1 antitrypsin deficiency can cause COPD in younger people.

Symptoms

Common symptoms

• Shortness of breath, especially during physical activity
• A persistent cough that produces mucus (phlegm)
• Wheezing or a whistling sound when breathing
• Frequent chest infections (bronchitis or pneumonia)

Symptoms in children

• COPD is very rare in children. If it occurs, symptoms may include a chronic cough, wheezing, or trouble keeping up with other kids during play.

Symptoms in older adults

• Symptoms are often similar to common COPD, but may be mistaken for normal aging. Watch for a nagging cough, shortness of breath with light activity, or frequent colds that settle in the chest.

Causes

Main causes

• Smoking cigarettes, cigars, or pipes (most common cause)
• Long-term exposure to lung irritants like air pollution, chemical fumes, or workplace dust (e.g., coal, grain, or textile dust)
• A rare genetic condition called alpha-1 antitrypsin deficiency that affects the lungs

Risk factors

• Age over 40
• Smoking or history of smoking
• Exposure to second-hand smoke, air pollution, or occupational dust/fumes
• Family history of COPD or alpha-1 antitrypsin deficiency
• Having poorly controlled asthma

When to see a doctor

See a doctor urgently if:

• If you have sudden severe breathing trouble, chest pain, blue lips/fingertips, or confusion, call your local emergency number immediately.

Book a routine appointment if:

• If you have a persistent cough that lasts more than a few weeks, especially with mucus
• If you get short of breath doing everyday tasks that used to be easy
• If you have frequent chest infections or colds that go to your chest

Diagnosis

COPD is diagnosed using a breathing test called spirometry, along with your medical history and a physical exam. The test measures how much air you can breathe out and how fast.

Tests that may be done

• Spirometry: you take a deep breath and blow as hard and fast as possible into a tube. The test is painless and takes 15–30 minutes.
• Chest X-ray or CT scan: to look at the lungs and rule out other conditions.
• Blood tests: to check for low oxygen levels and to test for alpha-1 antitrypsin deficiency.
• Pulse oximetry: a small clip on your finger to measure oxygen levels in your blood.

What to expect at your appointment

For spirometry preparation: your doctor may ask you to avoid smoking, heavy meals, and certain medications (like inhalers) for a few hours before the test. Wear loose, comfortable clothes that allow you to take a deep breath. You will be seated, use a nose clip, and breathe into a mouthpiece. The test is repeated a few times to get the best result. Your doctor will explain your results and what they mean for you.

Treatment

There is no cure for COPD, but treatments can help you breathe easier, prevent flare-ups, and improve your daily life. Treatment is tailored to your symptoms and stage of the disease.

Self-care at home

• Quit smoking – it is the most important step to slow the disease.
• Avoid lung irritants like smoke, strong fumes, and air pollution.
• Stay active with gentle exercise like walking or chair-based activities.
• Learn breathing techniques (e.g., pursed-lip breathing) to manage shortness of breath.

Medical treatments

Doctors may prescribe inhalers (bronchodilators and anti-inflammatory medicines) to open the airways and reduce swelling. Oxygen therapy can help if your blood oxygen levels are low. Pulmonary rehabilitation is a program that combines exercise, education, and support to help you manage COPD. Vaccinations (flu and pneumonia) are strongly recommended to prevent infections. Your doctor will work with you to find the best plan.

When is surgery considered?

In severe cases, surgery such as lung volume reduction (removing damaged parts of the lung) or a lung transplant may be considered. This is only an option when other treatments have not been enough and after careful evaluation by a specialist.

Living with this condition

Living with COPD means managing your symptoms day by day. You may need to pace yourself, use energy-saving techniques (like sitting while showering), and plan activities when you feel best. Many people with COPD lead full, active lives with the right care and support.

Lifestyle tips

• Quit smoking and avoid second-hand smoke.
• Stay away from air pollution, dust, and strong perfumes or cleaning products.
• Stay physically active as advised by your healthcare team.
• Get enough rest and drink plenty of fluids to keep mucus thin.

Diet and exercise

A balanced diet helps maintain a healthy weight, which is important for breathing. Exercise, such as walking or gentle stretching, can strengthen your lungs and muscles. Your doctor or a pulmonary rehabilitation team can create a safe plan for you.

Mental health and emotional wellbeing

COPD can cause feelings of anxiety or depression because of breathing difficulties and changes in daily life. It is important to talk to your doctor, a counselor, or a support group if you feel overwhelmed. You are not alone.

Prevention

The best way to prevent COPD is to never start smoking, or to quit if you do smoke. Avoiding lung irritants at work and at home also reduces risk. For people with alpha-1 antitrypsin deficiency, genetic counseling and avoiding smoking can help.

Vaccines

Getting the flu vaccine every year and the pneumococcal vaccine (as recommended by your doctor) can help prevent lung infections that can make COPD worse.

Screening programmes

Screening for COPD is not recommended for everyone, but if you have risk factors (like smoking history) and symptoms, talk to your doctor about a spirometry test. The earlier COPD is found, the more you can do to manage it.

Complications

If left untreated

• Frequent lung infections, such as pneumonia or bronchitis
• Heart problems, including high blood pressure in the lungs (pulmonary hypertension) and heart failure
• Weight loss and muscle weakness
• Depression and anxiety

Long-term outlook

With early diagnosis, proper treatment, and lifestyle changes (especially quitting smoking), most people with COPD can manage their symptoms and enjoy a good quality of life. The disease progresses over time, but treatment can slow it down. Stay in close contact with your healthcare team and follow your care plan.
