Stop Smoking

How Is Smoking Related to Diabetes?

We now know that smoking causes type 2 diabetes. In fact, smokers are 30–40% more likely to develop type 2 diabetes than nonsmokers. And people with diabetes who smoke are more likely than nonsmokers to have trouble with insulin dosing and with controlling their disease. The more cigarettes you smoke, the higher your risk for type 2 diabetes. No matter what type of diabetes you have, smoking makes your diabetes harder to control. If you have diabetes and you smoke, you are more likely to have serious health problems from diabetes. Smokers with diabetes have higher risks for serious complications, including:

  • Heart and kidney disease
  • Poor blood flow in the legs and feet that can lead to infections, ulcers, and possible amputation (removal of a body part by surgery, such as toes or feet)
  • Retinopathy (an eye disease that can cause blindness)
  • Peripheral neuropathy (damaged nerves to the arms and legs that causes numbness, pain, weakness, and poor coordination)

If you are a smoker with diabetes, quitting smoking will benefit your health right away. People with diabetes who quit have better control of their blood sugar levels.5 For free help to quit, call 1-800-QUIT NOW (1-800-784-8669) or visit CDC.gov/tips.

Bill's Story

Bill learned the hard way that smoking makes diabetes harder to control. At 37, he went blind in his left eye from a detached retina—damage to the inner lining of the eye. He also had kidney failure. Two years later, he had his leg amputated due to poor circulation—made worse from smoking. “I lost my leg, and that’s when I quit."
