How is diabetes affected by smoking?

Smoking also results in poorer control of blood sugar in those persons with known diabetes. In addition to all of the adverse health effects of smoking itself; in persons with diabetes, smoking doesn’t just add to those effects, it multiplies them.

Having diabetes multiplies smokers’ risks of cardio- and cerebrovascular disease. Smoking also increases the risk of diabetic complications – e.g. neuropathy, kidney disease, and others.

When you quit, insulin sensitivity and effect of diabetic drugs may improve with quitting so you need to watch their blood sugars closely. They may be lower than normal. This effect continues during tapering of their NRT, so be extra vigilant until you are totally off NRT.
