Chronic bronchitis is an inflammation of the main airways in the lungs that continues for a long period or keeps coming back.
Bronchitis - chronic
Causes, incidence, and risk factors
Cigarette smoking is the main cause of chronic bronchitis. The more a person smokes, the more likely it becomes that the person will get bronchitis and that the bronchitis will be severe.
Secondhand smoke may also cause chronic bronchitis. Air pollution, infection, and allergies make chronic bronchitis worse.
Chronic bronchitis is one form of chronic obstructive pulmonary (lung) disease . Chronic bronchitis, emphysema , and asthma as a group are a leading cause of death in the United States.
Chronic Obstructive Pulmonary Disease, or COPD for short, is the third leading cause of death in the United States. Millions of people have been diagnosed with COPD, and even more may have it and have not yet been diagnosed. It affects both men and women, and occurs most often in middle-aged and older adults.
COPD is a major cause of disability in its most severe stages, but it typically develops slowly over time. Symptoms, which include a chronic cough, chest tightness, wheezing and shortness of breath with activity, may be mild at first, but worsen as airways become more and more damaged. Eventually, symptoms begin to interfere with the activities of daily living, such as walking, cooking and even personal care.
COPD is not contagious, but there is no cure. Lung damage cannot be reversed, even with treatment, but the progression of the disease can be slowed with the proper care and lifestyle changes. This will allow you to feel better and stay more active.

The column looks to new studies to tell the actual difference; however common sense tells us the difference with or without clinical trials.
How are they different?
According to the New York Times: " The first is the onset of symptoms. Colds move more slowly, taking a day or longer to set in and gradually worsening - with symptoms like loss of appetite and headache - before subsiding after about a week and disappearing within 10 days. But allergies begin immediately. The sneezing is sudden and overwhelming, and the congestion, typically centered behind the nose, is immediate. Allergy symptoms also disappear quickly - almost as soon as the offending allergen, like pollen, is no longer around.
Then there are hallmark symptoms of each. Allergies virtually always cause itchiness in the eyes, the n...
