How does smoking affect insulin sensitivity?

It is well known that tobacco smoke is harmful to health and is of particular danger to people with diabetes. All of the chronic complications of diabetes – such as cardiovascular disease, foot problems, kidney disease, and eye damage – are exacerbated by breathing in tobacco smoke. Recently, it was suggested that smoking may increase the risk of developing type 2 diabetes. Although the exact mechanisms are not yet fully understood, it has been suggested that impaired sensitivity to the action of insulin in people who smoke tobacco could be linked to the rise in the number of people with type 2 diabetes. Giovanni Targher reports.
