The Link Between Smoking And Diabetes

smoking and diabetes, According to the latest WHO data, approx. 1.3 billion people on Earth smoke and one in two is expected to die from related diseases. Approx. Smoking in some form plays a role in the deaths of 8 million people.

The number of smokers in Hungary exceeds 2 million. a2019 statistics, 27% of people over the age of 15 smoke. In Hungary in 2019 approx. 28,000 people have died from a smoking-related illness, accounting for about 21% of all deaths.

Smoking plays a role in the development of many different diseases – such as cardiovascular diseases, malignancies, lung diseases.

Is smoking affected by all types of diabetes?

There are basically two main types of diabetes:

Type 1 diabetes: occurs due to an absolute lack of insulin produced by the pancreas – usually in adolescence. Total diabetes is about Type 1 diabetes accounts for 5%.

Type 2 diabetes: this is not an insulin deficiency. but a disorder of carbohydrate metabolism due to insulin resistance, which is often associated with inappropriate lifestyle habits and conditions (eg obesity, sedentary lifestyle, smoking). Smoking can play an important role in the development of type 2 diabetes. Smokers (compared to non-smokers) are 30-40% more likely to develop type 2 diabetes.

The longer a person smokes cigarettes, the more likely they are to develop diabetes.

What are the mechanisms by which smoking affects type 2 diabetes?

  • Nicotine found in tobacco products raises blood sugar levels. Persistently high blood sugar can lead to insulin resistance and, as a result, diabetes. As a result of high blood sugar. Increased insulin production over time leads to depletion of the pancreas, which builds up glucose in the blood, leading to diabetes.
  • Smoking maintains a chronic inflammatory condition in the body that reduces the effect of insulin.
  • It exposes the body to oxidative stress, which also contributes to the upset of carbohydrate metabolism and the development of diabetes.
  • Smoking can increase the levels of LDL cholesterol (‘bad cholesterol’) and triglycerides in the blood, while lowering HDL cholesterol (‘good cholesterol’). These metabolic changes also negatively affect carbohydrate metabolism.
  • In pre-existing diabetes mellitus that requires insulin therapy, smoking may make it difficult to prescribe appropriate therapy.

Smoking and diabetes: common risk factors for cardiovascular disease

smoking and diabetes are common risk factors for cardiovascular disease, the leading cause of death worldwide.

Why quit smoking?

Quitting smoking as soon as possible reduces the chance of developing serious illnesses, makes it easier to treat pre-existing illnesses, and reduces the incidence of complications.

If someone puts down a cigarette before a carbohydrate metabolism disorder develops, they have taken an important step to prevent their diabetes from developing – especially if they pay attention to other lifestyle factors (nutrition, exercise, maintaining an ideal weight).

However, it is not too late to quit smoking if you already have diabetes. According to some professional observations, as early as 8 weeks after smoking the last cigarette, insulin sensitivity improves, blood sugar levels fall, and diabetes is better treated. In addition, quitting smoking reduces the risk of developing serious complications associated with diabetes.

These include heated tobacco products, non-tobacco nicotine pads, and e-cigarettes. These technologies provide nicotine without burning and smoking, resulting in lower levels of exposure than traditional tobacco products.

Unfortunately, however, there are smokers who are unwilling to quit even with accurate knowledge of the harmful effects on health. For them, the use of smoke-free technologies can be a relative reduction in harm compared to the use of traditional “smoky” cigarettes, given the overall health effects.


No matter how you define it, smoking is harmful. You’re inhaling and exhaling smoke from something, after all. However, whether this is your own personal stash or some form of nicotine in the air. You still should quit for the sake of your health—and that of anyone who happens to be around at the time (second-hand smoke). The sooner someone put a cig out, and longer they have been away from the habit, the lower their risk will be—though it will never fully disappear.
