Does Smoking Put Me At A Higher Risk Of Developing Diabetes

Diabetes & Smoking

It has been established that there is a clear link between smoking and the risk of developing type 2 diabetes. Nicotine is one of the many chemicals that are found in cigarettes and is what makes smoking so addictive. When you smoke, nicotine changes the chemical processes in the cells inside your body so they do not respond to insulin. This is known as insulin resistance.

Insulin is the hormone that allows your body to use sugar from the food we eat for energy and stops your blood glucose level from getting too high. If your body starts to become resistant to insulin, then your blood glucose levels will rise and put you at an increased risk of developing type 2 diabetes.

Smoking And Diabetes Incidence

There is much evidence that smoking increases the risk of diabetes. Several cohort studies in Korea have reported that smoking was associated with an increased risk for the development of diabetes. Cho et al. followed 4,041 men for 4 years in rural and urban settings in Korea, and found that past and current smokers had a significantly increased risk for type 2 diabetes, and the risk increased with the number of cigarettes smoked. Another study reported a 14-year-long prospective cohort study, in which the risk of diabetes among men and women who smoked 20 cigarettes or more per day was 1.55 compared to those who never smoked .

A Japanese study reported similar results of a positive correlation between cigarette consumption and risk for diabetes . The health professionals’ follow-up study demonstrated that the risk for diabetes among men who smoked 25 cigarettes per day was 1.94 . Another British study showed the risk for diabetes in smoking men was around 1.7, after adjusting for confounding factors, such as age, body mass index, physical activity, alcohol intake, social class, and antihypertensive treatment .

There have been few studies on the effect of smoking on the risk of diabetes in women as generally the prevalence of smoking is lower in women than men. However, the results from the Nurses’ Health Study in the United States showed that the risk for diabetes in smokers was 1.42 after adjustment for other risk factors .

How Does Smoking Increase Complications For People Who Have Diabetes

While smoking can increase your chances of getting diabetes, it can also make managing diabetes more difficult for those who already have it. Smoking can worsen all of the above complications of high blood sugar, including eye disease, heart disease, stroke, vascular disease, kidney disease, nerve damage, foot problems, and many others.

How Does Smoking Make Me More Likely To Develop Diabetes

Smoking increases the risk of developing diabetes because it can change how your body processes and regulates sugar. Smoking can also make it harder to control your blood sugar levels if you have diabetes. If you smoke, you have a 30 to 40 percent higher chance of developing diabetes than someone who has never smoked.

And, the more you smoke, the higher your chance of developing diabetes. Once you quit, your risk of developing diabetes goes down. The longer you’ve been smoke-free, the less likely it is you’ll become diabetic.

Are There Any Benefits To Smoking

There are absolutely no benefits to smoking. People that smoke say that they find it relaxing, and it helps them deal with stress. In reality, it has the opposite effect. The nicotine in cigarettes is a stimulant and it is what people crave. You may feel some relief as you are temporarily satisfying the craving, but once youve finished your stress levels increase to more than what they were before having a cigarette.

Another common reason for smoking is that it keeps weight down, and people are worried about putting on weight if they stop. Smoking can suppress your appetite, but it doesnt necessarily mean that if you quit you will put on weight. Its important to know what could make you gain weight when you stop so that you are prepared and avoid this.

Smoking Cessation May Actually Increase Risk Of Developing Type 2 Diabetes

The researchers suspect the elevated diabetes risk is related to the extra pounds people typically put on after renouncing cigarettes and caution that no one should use the studys results as an excuse to keep smoking, which is also a risk factor for lung disease, heart disease, strokes and many types of cancer.

The message is: Dont even start to smoke, says study leader Hsin-Chieh Jessica Yeh, Ph.D., an assistant professor of general internal medicine and epidemiology at the Johns Hopkins University School of Medicine.

If you smoke, give it up. Thats the right thing to do. But people have to also watch their weight, she adds.

In the study, published in the January 5 issue of Annals of Internal Medicine, researchers found that people who quit smoking have a 70 percent increased risk of developing type 2 diabetes in the first six years without cigarettes as compared to people who never smoked. The risks were highest in the first three years after quitting and returned to normal after 10 years. Among those who continued smoking over that period, the risk was lower, but the chance of developing diabetes was still 30 percent higher compared with those who never smoked.

The study enrolled 10,892 middle-aged adults who did not yet have diabetes from 1987 to 1989. The patients were followed for up to 17 years and data about diabetes status, glucose levels, weight and more were collected at regular intervals.

Additional Risks Of Smoking

Smoking Cessation For People With Diabetes

Does Smoking Affect Diabetes?

Abstinence from smoking will certainly produce specific benefits in patients with diabetes. This fact is reflected in the most recent guidelines on diabetes treatment which include smoking cessation as a key chapter. Current guidance highlights the importance of stopping smoking for patients with diabetes to achieve a better quality of life and to delay the onset and progression of diabetes complications.

The currently available smoking cessation therapies have been shown to double or even triple the dropout rates in controlled studies . A recent study in patients with DM yielded a smoking cessation rate of 11.1% at 6-months in those undergoing an intensive smoking cessation program . However, according to a survey by Diabetes UK, 64.1% of smokers with DM do not receive any assistance or advice to quit far too many. Another constraint to cessation treatment is the absence of a convincing demonstration of an effective cessation interventions in patients with DM . Further studies will be needed to provide clear evidence that which interventions can be valuable for these patients. As a consequence the smoking prevalence among patients with DM continues to be similar to that found in the general population with a significantly less marked decrease trend in patients with diabetes compared to the general population . These conditions mean that helping patients with diabetes to quit requires a greater commitment and the use of personalized anti-smoking strategies.

Smoking and diabetes both increase the risk of heart disease in similar ways. This means that when combined they greatly increase your chance of developing a heart-related condition such as a heart attack or stroke.

High levels of glucose in your blood and smoking both damage the walls of your arteries in a way that means fatty deposits can build up much easier. This is known as atherosclerosis. As atherosclerosis occurs, your blood vessels narrow and therefore blood flows through less easily.

When this happens to your coronary arteries you can have a heart attack or angina. When this happens to the arteries that take blood to your brain, you can have a stroke.

There are two primary types of diabetes:

Individuals with Type 1 diabetes do not produce insulin, which is a hormone produced by the pancreas for converting the glucose and carbohydrates that we eat into energy the body can use.3 Though it has been referred to in the past as juvenile diabetes, this type of diabetes can develop at any age, in any race, and is not related to body weight. Approximately 5 percent of diabetics have Type 1 diabetes these individuals must use insulin therapy.4

Individuals with Type 2 diabetes have an abnormality in the way their bodies use insulin that causes blood sugaror blood glucoseto be too high. People with Type 2 diabetes may have adequate or even elevated levels of insulin, but their bodies cannot use it properly.5 Type 2 diabeteswhich accounts for more than 90 percent of all diabetes cases6is a serious condition. In the past, Type 2 diabetes was thought to be a disease primarily seen in adults and acquired later in life. However, in the last 20 years, there has been an increase in the incidence of Type 2 diabetes in children and adolescents.
