reasons of copd

The causes of COPD is complex and not yet fully understood. It may be the result of the long-term influence of various environmental factors and the body’s own factors.

There are currently 5 main causes of chronic obstructive pulmonary disease.

Harmful chemicals in cigarettes can paralyze the cilia in the trachea. It also damages the bronchioles and alveolar walls. It also irritates the airways to produce an inflammatory response and cough. Resulting in increased secretions. Current research shows. Smoking remains the main and most common cause of COPD. Most COPD patients are long-term smokers. Studies have reported that the prevalence of COPD is significantly higher in current and former smokers than in never-smokers.

Active smoking clearly causes a variety of respiratory diseases. In fact, secondhand smoke is also threatening people’s health. Even people who are chronically exposed to secondhand smoke have a higher risk of developing COPD.

Coal miners who have been exposed to industrial dust for a long time are prone to chronic obstructive pulmonary disease.

Long-term exposure to industrial pollution such as

• silicon
• cotton wool
• coal
• petrochemicals

People’s airways are prone to inflammation. This leads to mucosal edema and bronchospasm.

• virus infection
• Infection with bacteria
• Infection with pathogens such as mycoplasma

Air pollution increases sticky secretions in the respiratory tract. Cause chronic cough, making sputum difficult to cough up. It can also make COPD worse.

Air pollution increases the risk of exacerbation of COPD when a patient’s symptoms are acutely exacerbated and persist without improvement. Long-term indoor cooking and exposure to biofuels (such as wood, charcoal, etc.) can also cause COPD.

Some of the own factors can make an individual more susceptible to COPD, mainly including:

• Genetic abnormalities (eg, antitrypsin deficiency)
• Abnormal lung development
• Immune dysfunction
• Occurrence of lower respiratory tract infections (eg, colds, pneumonia, bronchitis)
• Increasing age. The lungs age with age, creating a phenomenon that resembles an airway obstruction.

When tobacco, dust, pathogens and other factors repeatedly stimulate the respiratory tract, it can trigger an inflammatory response in the alveoli and respiratory tract. Or damage airway epithelial cells and damage lung elastic fibers. Thereby induce chronic bronchitis or lead to emphysema. These conditions can make airway ventilation difficult. Over time, it gradually develops into chronic obstructive pulmonary disease.
