A chronic disease caused by persistent exposure to tobacco?

Question: A chronic disease caused by persistent exposure to tobacco? 

One of the most common and serious chronic diseases caused by persistent exposure to tobacco is **chronic obstructive pulmonary disease (COPD) . COPD is a progressive lung condition that makes it hard to breathe and can lead to life-threatening complications. COPD includes two main types: **emphysema** and **chronic bronchitis**. Emphysema damages the air sacs in the lungs, while chronic bronchitis causes inflammation and mucus in the airways.

According to the World Health Organization (WHO), tobacco smoking is the leading cause of COPD, accounting for more than 90% of COPD deaths worldwide . Smoking tobacco damages the lungs in various ways, such as reducing the elasticity of the airways, increasing inflammation, impairing the function of cilia (tiny hairs that clear mucus and particles from the lungs), and destroying the alveoli (tiny air sacs that exchange oxygen and carbon dioxide). These changes result in airflow obstruction, coughing, wheezing, shortness of breath, chest tightness, and increased risk of infections.

COPD is a preventable and treatable disease, but there is no cure for it. The best way to prevent or slow down the progression of COPD is to quit smoking or avoid exposure to secondhand smoke . Quitting smoking can also improve the symptoms and quality of life of people with COPD. Other measures that can help people with COPD include taking medications, using oxygen therapy, participating in pulmonary rehabilitation, getting vaccinated against flu and pneumonia, and avoiding triggers such as air pollution, dust, and chemicals.

COPD is a serious public health problem that affects millions of people around the world and causes significant morbidity and mortality . It is important to raise awareness about the harmful effects of tobacco smoking on the lungs and to encourage smokers to quit or reduce their tobacco consumption. By doing so, we can prevent or delay the onset of COPD and improve the health and well-being of millions of people.
