Second-hand smoke increases diabetes risk

Cigarette smoke is known to be one of the leading contributors to the development of type 2 diabetes. However, the effect on the friends and family of smokers until recently went untested.

Now, a new study from Korean researchers has confirmed that second-hand smoke greatly increases an individual's risk of developing the chronic illness, according to the Korea Herald.

For the study, researchers from the Korea Centers for Disease Control followed more than 4,000 non-smokers. They found that the individuals who reported being exposed to second-hand smoke on a regular basis were 1.4 times more likely to develop type 2 diabetes than those who are free from second-hand smoke.

"Cigarette smoke contains more than 4,000 harmful chemicals, including at least 50 cancer-causing substances," Kim Sung-soo, who led the research, told the news source. "When inhaled, it induces insulin resistance in which the hormone becomes less effective at lowering blood sugars."

The American Diabetes Association says that smoking causes major damage to the blood vessels and increases the risk of insulin resistance. Avoiding cigarette smoke may cut down on the chances of developing type 2 diabetes.
