Increased Diabetes Risk For Those Who Quit Smoking

Researchers at Johns Hopkins note that smoking is a well-known risk factor for type 2 diabetes.  New research points out that elevated diabetes risk is related to the extra pounds people typically put on after renouncing cigarettes. 

Type 2 diabetes is a common disease that interferes with the body’s ability to properly use sugar, and to regulate and properly use insulin, a substance produced by the pancreas that normally lowers blood sugar during and after eating.

“No one should use the study’s results as an excuse to keep smoking, which is also a risk factor for lung disease, heart disease, strokes and many types of cancer,” explains Jesse Slome, executive director of the American Association for Critical Illness Insurance.

The study which was published in the January 5 issue of Annals of Internal Medicine reported that people who quit smoking have a 70 percent increased risk of developing type 2 diabetes in the first six years without cigarettes as compared to people who never smoked. 

The risks were highest in the first three years after quitting and returned to normal after 10 years. Among those who continued smoking over that period, the risk was lower, but the chance of developing diabetes was still 30 percent higher compared with those who never smoked. 

The study comprised nearly 11,000 middle-aged adults who did not yet have diabetes from 1987 to 1989. The patients were followed for up to 17 years and data about diabetes status, glucose levels, weight and more were collected at regular intervals. 

According to the study, those who smoked the most and those who gained the most weight had the highest likelihood for developing diabetes after they quit. On average, over the first three years of the study, quitters gained about 8.4 pounds and saw their waist circumferences grow by approximately 1.25 inches.
