Research shows that smokers have high chances of developing type 2 diabetes. The chances increase with a number of cigarettes smoked per day whereas the non-smokers have less tendency to develop diabetes.
HOW SMOKING CONTRIBUTES TO DIABETES?
BY INFLAMMATION: Due to smoking, body cells are injured and get inflamed due to the chemicals in cigarette smoke.
OXIDATIVE STRESS: The cigarette smoke combines with atmospheric oxygen as a result the body’s cells are injured
ABDOMINAL OBESITY: There is a direct association between smoking and abdominal obesity, which in turn causes blood sugar to go up.
Generally, people who smoke need higher doses of insulin than non-smokers. A smaller dose is not effective because it gets exposed to nicotine, reducing its efficacy.
