What can be done to prevent the condition?

Many risk factors for chronic bronchitis can be completely eliminated. Smoking cessation is vital for those who smoke. Sources of indoor air pollution can be identified and removed. It is also important to avoid secondhand smoke.

What are the long-term effects of the condition?

Chronic obstructive pulmonary diseases, including chronic bronchitis, are the fourth leading cause of death in the world. The long-term effects depend on how severe the disease is when diagnosed and if a reduced exposure to the lung irritant occurs. The most effective treatment is quitting smoking. This will typically result in a modest improvement or no further decline in function.

People with chronic bronchitis have a higher mortality than those with normal lung function. Causes of death include respiratory failure, lung infections such as pneumonia and influenza, and other diseases related to smoking. These include cancer, heart disease, and stroke.

What are the risks to others?

Chronic bronchitis is not contagious and poses no risk to others.
