Chronic Obstructive Pulmonary Disease (COPD) refers to a group of lung conditions that block the airflow and create issues in breathing. Typically, people with this condition have emphysema and chronic bronchitis or both of these conditions. The health problem causes harm to the lungs and is progressive. It can last for several years or be lifelong. There is no one-size-fits-all answer for determining the life expectancy of people with this condition. But factors like age, lifestyle, health, and severity can affect the lifespan. Here is all you need to know about the life expectancy of COPD patients.
COPD severity and life expectancy
To determine the severity of COPD, doctors use a classification system known as Global Initiative on Obstructive Lung Disease (GOLD). It makes the calculation based on the quantity of air you can exhale in one second after blowing air into a spirometer. Also known as the forced expiratory volume test, GOLD considers the results of an adult who is your age, gender, and the ethnic group without COPD to determine your severity. So, for example, if you can blow up to 80% of a normal person’s air into the spirometer, you will be categorised as a stage 1 patient.
GOLD1 people have mild COPD, and FEV1 is more than 80%.
GOLD2 patients have moderate COPD, and FEV1 is between 50% and 79%.
GOLD3 has severe emphysema or chronic bronchitis. Their FEV1 is between 30% and 49%.
GOLD4 people are identified with very severe COPD. Their FEV1 is less than 30%.
The higher you score on the GOLD system, the lesser your life expectancy.
The link between symptoms and severity:
Based on symptoms like breathing problems, COPD flare-ups, and exacerbations, doctors divide patients into A to D categories. People who are part of group D are the most serious. Such people have high symptom severity, and the risk of exacerbation is more.
What is the role of smoking?
Smoking is the leading cause of COPD. For people who are 65 and smoke, the drop in life expectancy is as follows:
Stage 1: 0.3 years
Stage 2: 2.2 years
Stage 3: 5.8 years
Stage 4: 5.8 years
Can medication prolong life expectancy?
At present, we don’t know of any medications that can cure COPD or slow its progression. But, we can try bronchodilators that improve shortness of breath and open airways. Corticosteroids can control the flare-ups, and the patient might be prescribed supplemental oxygen. People who do not have access to healthcare and no insurance are likely to have complications and die early.
Can non-invasive ventilation prove helpful?
Those looking for the Non-Invasive Ventilation (NIV) definition should know that the treatment delivers oxygen into the lungs via positive pressure without using endotracheal intubation. NIV improves survival in COPD patients and improves their quality of life.
COPD refers to chronic lung disease. Although the health condition is life-threatening, with proper treatment and precautions COPD patients can live into their 70s, 80s, and 90s.
