Chronic bronchitis is a lung disease that causes a cough with increased mucus production for at least three months in two consecutive years. It generally falls under the category of chronic obstructive pulmonary disease, or COPD.
The most common cause is cigarette smoking, although the inhalation of irritants at work, air pollution and lung infections may also cause it. Considering most people develop this disease due to exposure to cigarette smoke, one might wonder: Why does smoking cause chronic bronchitis?

Most of my more distant relatives did not know of my dementia diagnosis since I was diagnosed within the last six months. After hugs and greetings, small talk began, which these days is usually about everyone's health.
