Advice if you smoke

Smoking increases the risk of developing the well-known complications of diabetes. Smoking also raises your blood glucose levels and increases your body’s resistance to insulin (due to nicotine).

Smoking significantly increases the risk of a heart attack or a stroke. As people with diabetes are already at higher risk of this due to diabetes, the total risk increases about four-fold.

Furthermore, experts agree that smoking (tobacco) is the single biggest avoidable cause of cancer in the world.

Health benefits

The health benefits of stopping smoking are huge and immediate:

What support is available to help me quit?

The good news is that there is a lot of support available to help you stop smoking. The first stop for many is their GP or healthcare professional. They can signpost you to local programmes that are free to attend and are staffed by expert advisers that will help find the best method to quit.

Sometimes this might be a group support session or a one-to-one meeting with a smoking advisor. Overall you are 4 times more likely to stop smoking for good if you engage with an NHS Stop Smoking Service that can offer a mixture of different treatments. To find what Stop Smoking Services are available in your area, put your postcode into the finder on the NHS Smokefree website.

We live now in a digital age and there are many digital tools that you can use to help you quit. Have a look at the NHS Smokefree website which has lots of information and you can design your own personal plan. They also have their own Smokefree app which is available to download for free on both the Apple App Store and Google Play.

    Took me four attempts to stop smoking. Used champix in the end to stop which worked. I felt badly sick while taking it which was a side affect but I struggled through to the end. Unfortunately I put nearly two stone on but managed to get back to 10 stone over time. Also I got rid of my bad cough and feel so much healthier. Wasn’t easy to do but worth the benefits.
