Chronic Bronchitis involves chronic inflammation, a cough and increased mucous production, which causes narrowing of the airways. The system of tiny hairs that clear mucous from the lungs become damaged, allowing secretions to remain in the airways. The narrowing and obstruction of the airways decreases the flow of air into and out of your lungs.

Emphysema is caused by damage to the small sacs (alveoli) in the lungs and the destruction of their walls. The lungs lose their elasticity and air becomes trapped in the lungs. The destruction of the sacs causes the lungs to become less efficient at exchanging oxygen and carbon dioxide with the blood.

Ottawa, ON, November 20, 2007 – Startling research findings released today by The Lung Association demonstrate that as many as three million Canadians may have COPD (Chronic Obstructive Pulmonary Disease), Canada's fourth leading cause of death. This is nearly double previous estimates and includes over one and a half million (1.6 million) undiagnosed Canadians and one and a half million (1.5 million) who say they currently suffer from this chronic lung disease. 

The research also shows that the disease is highly prevalent among younger Canadian baby boomers - one in seven Canadians aged 45 to 49 (375,000) may have COPD.

This research confirms recent global prevalence data published in The Lancet which states "…evidence suggests that rates of disease (COPD) are generally underestimated."

• Bronchodilators (relievers): Bronchodilators work by relaxing the smooth muscles around the airways, allowing for improved air flow.
• Anti-inflammatories (preventers): These medications reduce inflammation in the airways.
• Antibiotics (for bacterial infections): Antibiotics kill bacteria and are used if an infection is suspected.
• Home Oxygen to reduce your shortness of breath and improve the quality of your life

Other treatments include proper nutrition and hygiene, exercise and rehabilitation programs.
