Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung condition that makes breathing difficult. It’s often underdiagnosed because early symptoms are mild and easily dismissed. Understanding COPD can help you recognise symptoms early and seek treatment before significant lung damage occurs.<\/p>\n\n

\n COPD is one of the leading causes of death worldwide, yet many people don’t know they have it. The most common cause is smoking, but long-term exposure to air pollution, dust, and chemicals can also contribute.\n<\/div>\n\n <\/section>\n\n \n\n
\n

What Are the Symptoms<\/em>?<\/h2>\n

COPD symptoms usually develop slowly and worsen over time:<\/p>\n\n

\n
\n

Chronic cough<\/p>\n

A persistent cough that lasts for months or years, often called a “smoker’s cough.” This is usually one of the earliest symptoms.<\/p>\n <\/div>\n

\n

Phlegm production<\/p>\n

Regular production of mucus or sputum from the chest, especially in the morning.<\/p>\n <\/div>\n

\n

Breathlessness<\/p>\n

Feeling short of breath during activities that used to be easy, such as walking up stairs or carrying groceries. This tends to worsen over time.<\/p>\n <\/div>\n

\n

Wheezing<\/p>\n

A whistling or squeaking sound when breathing, especially during exhalation.<\/p>\n <\/div>\n

\n

Frequent chest infections<\/p>\n

Being more susceptible to colds, bronchitis, and pneumonia that take longer to recover from.<\/p>\n <\/div>\n<\/div>\n\n <\/section>\n\n \n\n

\n

What Are the Causes<\/em>?<\/h2>\n

The most common cause of COPD is long-term exposure to lung irritants. The single biggest risk factor is smoking, but other factors can also contribute:<\/p>\n\n

\n
\n

The #1 cause of COPD. Both current and former smokers are at risk. The more you smoke and the longer you smoke, the higher your risk.<\/p>\n

Up to 75% of COPD cases are in smokers or ex-smokers<\/p>\n <\/div>\n

\n

Air pollution and occupational exposure<\/p>\n

Long-term exposure to air pollution, secondhand smoke, dust, fumes, and chemicals (e.g., in certain workplaces) can damage the lungs and lead to COPD.<\/p>\n

World Health Organization<\/p>\n <\/div>\n

\n

Genetic factors<\/p>\n

A rare genetic condition called alpha-1 antitrypsin deficiency can cause COPD, even in people who have never smoked. Family history also increases risk.<\/p>\n

NHLBI<\/p>\n <\/div>\n

\n

Age and previous lung infections<\/p>\n

COPD is more common in people over 40. Severe childhood respiratory infections and asthma may also increase risk.<\/p>\n

\n

How Is COPD Treated<\/em>?<\/h2>\n

COPD cannot be cured, but treatment can slow progression, relieve symptoms, and improve quality of life:<\/p>\n\n

\n
\n

Smoking cessation<\/p>\n

The single most important step. Quitting smoking at any stage of COPD can slow disease progression and improve symptoms.<\/p>\n <\/div>\n

\n

Medications<\/p>\n

Bronchodilators (inhalers) help open airways, while steroids reduce inflammation. Your doctor will prescribe the right combination for you.<\/p>\n <\/div>\n

\n

Pulmonary rehabilitation<\/p>\n

A structured programme combining exercise training, breathing techniques, and education to improve lung function and quality of life.<\/p>\n <\/div>\n

\n

Oxygen therapy<\/p>\n

For severe COPD, supplemental oxygen may be needed to maintain adequate oxygen levels in the blood.<\/p>\n <\/div>\n<\/div>\n\n <\/section>\n\n \n\n
