Although there are thousands of diseases that commonly effect many people and their loved ones, there are few chronic diseases that are putting a huge strain on health care systems acroiss the world.
The following seven chronic diseases have been affected more and more people with increasing frequency in developed nations across the world.
About six of every 10 people in the United States age 18 and older have at least one chronic medical condition, according to the latest News and Numbers from the Agency for Healthcare Research ands Quality.
A chronic condition is one that can be expected to last at least one year and result in limitations or the need for ongoing medical care.
For example, in 2005 about 22 million Americans received medical care for osteoarthritis and related conditions, 49 million for asthma or chronic obstructive pulmonary disease, 17 million for diabetes, 45 million for hypertension, and 19 million for heart disease, according to AHRQ.
When AHRQ analyzed chronic conditions as a whole in 2005, it found that:
- Nearly 4 in 10 Americans between 18 and 34 years of age had at least one chronic condition, as did 9 of every 10 aged 65 and older.
- About 77 percent of Americans aged 65 and older had two or more chronic conditions. Only 14 percent of those 18 to 34 had two or more conditions.
- Nine of every 10 dollars spent for medical care (excluding expenses for dental care and medical equipment and supplies) on adults in the United States was spent to treat persons with chronic conditions.

Research presented at the American Society of Hypertension's Twenty Third Annual Scientific Meeting and Exposition (ASH 2008) shows that even a few hours of exposure to particulate matter (PM), which is not ozone but a component of air pollution emitted from power plants, factories and motor vehicles, among other sources, is responsible for rapidly raising blood pressure and can impair blood vessel function in certain situations within 24 hours.
The effect of particulate matter on blood pressure may explain why air pollution can trigger a large host of cardiovascular events including heart attack, heart failure, other forms of heart disease and stroke. It is also important to understand, since particulate matter is the 13th cause of mortality worldwide.
