New research has established an association between traffic-related air pollution and the risk of developing Type 2 diabetes in women. Air pollution is already known to increase a person’s risk of developing cardiovascular disease.

To determine whether exposure to air pollution and the development of Type 2 are linked, researchers in Germany looked at 1,775 women ages 54–55 who had not been diagnosed with diabetes at the beginning of the study in 1985. Data on air pollution from monitoring stations and emission inventories run by environmental agencies were used to determine the women’s average levels of air pollution exposure.

Between 1990 and 2006, 187 participants were diagnosed with Type 2 diabetes. Exposure to elements of traffic pollution such as nitrogen dioxide and particulate matter was found to have a significant association with a higher risk of developing Type 2. Living within 100 meters of a busy roadway more than doubled the risk.

The researchers were able to predict the women’s increased risk of diabetes by measuring their levels of a blood protein known as C3c, which is an indicator of inflammation. Although the relationship of C3c to diabetes is not clear, it is suggested that air pollutants might react with immune cells in the airways, leading to widespread inflammation that makes a person more susceptible to diabetes.

The study focused on women only; lead study author Wolfgang Rathmann, MD, MSPH, notes, “We have no reason to assume sex differences in the association between air pollution and diabetes risk, but we do not have data on this issue.”

  1. WELL HERE GOES, IT WAS 1994 AND I WAS DIAGNOSED WITH TYPE 2 DIABETES. IN 2008 I HAD GASTRIC BYPASS SUGERY BUT GUESS WHAT THE DIABETES GOT WORSE. I HAD THE SERUM ASSAYS DONE AND FOUND OUT I HAD TYPE 1 DIABETES ALL OF THAT TIME. I HAD AT THAT POINT BEEN ON INSULIN FOR OVER 10 YEARS. I WAS VERY DEPRESSED FOR ABOUT A YEAR AFTER THAT AND COULD NOT QUITE BELIEVE IT. I ALSO HAVE TWO CHILDREN NOW ADULTS DIAGNOSED AT AGE 1 1/2 YEARS WITH JUVENILE DIABETES.

    HAS ANYBODY ELSE HAD GASTRIC BYPASS JUST TO SEE THAT THEIR DIABETES DID NOT GO AWAY OR THAT THEY HAD TYPE 1.

    E-MAIL ME OR BLOG HERE. THANKS CINDY W.

  2. I’ve heard a lot of misdiagnosed as type 2 stories but your misdiagnosis had serious health implications for you (e.g. gastric bypass). I hope that you are doing well without any complications from the surgery. I, too, was misdiagnosed as type 2 but the only thing that happened to me is that I dropped from 155 to 109# in the course of 2 years. What finally gave them a clue something else was going on was that my sugars jumped to between 200-350 and oral meds didn’t budge it at all. It was a couple of frustrating and anxious years to not be able to eat much at all and still not have great numbers. But that’s nothing compared to what you’ve gone through.

  3. Cindy,

    I am curious as to why gastric Bypass surgery was recommended for Diabetes.

    Research and education has led me to look for the underlying cause to Diabetes. Looking at Chromium levels, and what is triggering an insulin surge in the first place. This leads naturally to diet. What is your refined carbohydrate intake, sugar intake ect.

    Looking at metabolism may be the answer.

    I do want to know the philosophy behind gastric bypass surgery eliminating diabetes.
    Thanks,
    Karen

  4. I’ll hold my breath. Oh, but I already have type 2! Too late.

  5. Hey! because of an earlier article, I now drink a glass of crystal light lemonade with a capful of cider vinegar twice daily. My glucose numbers have dropped considerably. The vinegar actually makes the lemonade sweeter.

  6. Actually, there appears to be substantial and growing evidence that gastric bypass surgery “resolves” type 2 diabetes in up to 70% of patients.

    See, for example, http://www.medicinenet.com/script/main/art.asp?articlekey=47582

    Or, simply do a search for diabetes and gastric bypass.

  7. Cindy,
    I am so sorry to hear about what you have gone through. I was diagnosed with type 1 almost two years ago, at the age of 36. Luckily, the doctors figured out which type I had right away. I know that many people who develop it later in life can go for years until they get the correct diagnosis.
    I don’t know much about gastric bypass, but I do know that it is generally recommended for people who are very overweight, diabetic or not. Being severely overweight is not good for people with type 1 diabetes either, so even though you didn’t get rid of the diabetes, the surgery should hopefully still be beneficial.
    You can also have type 1 and be insulin resistant. I take metformin in addition to my insulin to help with some insulin resistance. (I am about 30 pounds overweight.)
    I’m glad that they finally figured out what type of diabetes you have, and I hope that you are able to keep your numbers under better control now.

    PS. Not clear on how yhis all relates to the link between polution and type 2 diabetes.

  8. Diabetes 2 is an honorable disease. It does not respond to reduction in carbs in all cases. Each case appears to be mediated by individual biologic differences. I went on a totally protein diet to see if it would reduce my blood glucose. The glucose went down a few points, not enough to warrant staying on this diet, which by itself may end up causing kidney and liver problems. Not enough research has been done about diabetes 2 even though millions of people have it. I personally believe it is related to chemicals put into foods to extend their shelf life. I note that as more and more commercial prepared foods are on the grocery shelves more people are getting diabetes 2. They try to blame it on overweight people but there were overweight people in earlier days when we had personal gardens are raised our own food. There were many less cases of diabetes 2 in those days. Many of the additives/pesticides in food are closely related to molecules simulating female sex hormones. These contaminants are causing multiple diseases, diabetes, prostate cancer, breast cancer, pancreatic cancer etc. Our government is so corrupted by manufacturers of food and pharmaceuticals that they say nothing and do nothing even though they know that our food chain is killing us all.

  9. Oh, this hits home very hard for me. I worked as a parking lot attendant for 18 and half years. We stood out in the chocking fumes for hours on end. Now I have type 2 diabeltes. It’s a knife in my heart.

  10. “I do want to know the philosophy behind gastric bypass surgery eliminating diabetes.”

    Bypass surgery just does this mechanically instead of with medication. I hope this makes some sense. All this stuff with encretins is a fairly new biological concept on how glucose metabolism is regulated.

  11. Sorry in submision a whole section on how the encretin system of dpp4 and GLP-1 combine to impace glucose intake and processing - and how bypass surgery impacts this got eliminated in my post…. Short story the upper small intestine when bypassed doesn’t release as much of a regulating hormone (dpp4) that turns-off a system that signals a number of activities which all act to minimize higher levels of blood glucose when carbohydrates are digested by the stomach. This is the encretin system, and it is what drugs like Januvia, Byetta, and Victoza impact. Bypass surgery creates this effect by “bypassing” the upper small intestine in digestion.

    Thanks…

  12. Back to the blog about air pollution causing type e 2 diabetes - I don’t buy it from the description in the blog. My opinion based on the blog is that a cause of inflammation is correlated with diabetes. My question would be: Are other equally potent causes of inflammation related to typr 2 diabetes?

    Posted by St. Paul Mike |
  13. St. Paul Mike asks if other causes of inflammation are related to Type 2. Yes, they are. And anti-inflammatory medicines have been shown to reduce insulin resistance and glucose numbers, as I have blogged about before.

    David Mendosa wrote a good article about inflammation causing diabetes at
    http://www.healthcentral.com/diabetes/c/17/73865/inflammation-root

    Note that bypass surgery has a strong effect on Type 2, but not because of weight loss. Weight is still not proven to be a cause of Type 2, only a risk factor.

  14. I have just finished the manditory classes required by Kaiser before they will preform the Gastric Bypass Operation. Apparently when the bottom of the stomach and the first few inches of the intestines are removed Diabetes goes into remission for almost 90% of Type 2 patients. There has been much debate about preforming the operation on normal sized people with diabetes, but because of how the operation was certified there is FDA proceduaral problems. Anyway the Diabetes is not resolved, but is in remission, and will return with a weight gain after the initial weight loss.
