Smoking has severe effects on your diabetes and your health. Quitting smoking will give you more energy, better control of your diabetes, and less chance of a heart attack or stroke.

Blood sugar:

Smoking raises your blood glucose (sugar) and reduces your body's ability to use insulin, making it more difficult to control your diabetes.


Smoking can make vision problems worse and raise your risk of blindness.


Smoking raises your risk of getting gum disease and losing your teeth.


Smoking increases your risk of nerve damage, which can cause numbness, pain and problems with digestion.


Smokers with diabetes are eleven times more likely to have a heart attack or stroke than people who don't have diabetes and don't smoke.


Smoking triples your risk of kidney disease. Drugs that help prevent kidney failure don't work as well for smokers.

Feet and legs:

Smoking can lead to serious foot and leg problems, like infections, ulcers, and poor blood flow, and raises your risk of amputation.


Many people with diabetes have high levels of cholesterol. Smoking makes this worse by increasing buildup on artery walls, putting you at more risk for heart attack or stroke.

Smoking is awful and it is costly. It hits your pocket and your health. I'll quit today, honestly. No more smoking. I do care about my well-being, so that's why I'm quitting.

It would be interesting to hear more about the effects of smoking on people who have Type 1 diabetes. Also, It would be great if you would not refer to people who have type 1 or 2 diabetes as diabetics. The disease doe NOT define us. It is no different than saying someone is a leper when they happen to suffer from leprosy. It is rather degrading to be known as our disease. We didn't ask for it.

I would be very interested in knowing HOW smoking raises your glucose, and what evidence is of a glycemic rise! A flat statement that "smoking raises your blood glucose" doesn't mean that it's true.

On what research or evidence are they basing the statement "Smoking raises your blood glucose (sugar)" ???
