Use Of Diabetes Medication Linked To Vitamin B-12 Deficiency

May 27, 2010 by  

Use of diabetes medication linked to vitamin B-12 deficiency Diabetic patients who are prescribed the drug metformin may be at an increased risk of developing a vitamin B-12 deficiency, according to a new European study.

Lead author Coen Stehouwer believes that individuals who take the medication should routinely monitor their vitamin B-12 levels and may want to consider taking nutrient supplements.

For the study, the research team recruited 390 patients with type-2 diabetes and assigned them to take either metformin or a placebo three times each day for four years.

At the point of follow-up, participants who were prescribed the diabetes medication experienced a 19 percent reduction in their vitamin B-12 levels. A total of 17 once-healthy participants developed a severe nutrient deficiency over the course of the research.

"Our study shows that it is reasonable to assume harm will eventually occur in some patients with metformin-induced low vitamin B-12 levels," said Stehouwer. "Our data provide a strong case for routine assessment of vitamin B-12 levels during long-term treatment with metformin."

Vitamin B-12 deficient patients often experience fatigue, anemia and significant mental changes.

    Education via information is the key, people. The AMA/FDA cabal cares not a whit about your health. The AMA crowd is indoctrinated to believe that everything they learn in medical school is infallible. The FDA herd is indoctrinated to believe that they’re all-powerful.
    The American people are caught between the AMA and the FDA. Big Pharma is the Gestapo arm of the AMA/FDA cabal. An informed America keeps the AMA/FDA/Big Pharma dictatorship from enslaving us.
    Readers can inform themselves via a book titled Drug-Induced Nutrient Depletion Handbook [Pelton, LaValle, Hawkins and Krinsky]. This book should required in medical schools (assuming that our healthcare professionals can find a reason to value lives over MONEY, instead of MONEY over lives).

    By the way, folks, for someone who takes that particular drug in the above article (metformin), you can also expect to become deficient in folic acid.
    If you have complete faith in the AMA/FDA/Big Pharma herd, ask your MD why he didn’t tell you about being deficient in B12 AND folic acid. Funny how little details like that aren’t taught in medical schools. Maybe the inability to read affects more than those career retards in Congress, eh?
    You almost get the impression that Big Pharma controls the AMA and the FDA, and that MONEY is what matters most to these dictators. Here’s to your good health, your continuing education and here’s to the humiliation and elimination of Big Pharma, the FDA and the AMA. No one can afford to be under those thumbs – unless you like slavery, bad health and being broke.

    Good News for S C:

    Get yourself a new doctor! When my doctor prescribed metformin for my type II she also suggested a B12 and a Folic Acid supplement. Your doctor must have slept thru that part of the class and your rant on the entire industry is just another liberal progressive diatribe.

      JA, you’re new to this website if you think I’m a stinking liberal. First, MOST American MDs DO NOT care about patients to properly inform them about nutritional deficiencies via drugs. You may live in a vacuum. I don’t. Your words make you sound like an AMA/FDA stooge. Hopefully, you care about good health, but I WON’T make that assumption.
      Second, I don’t have that particular health problem. When I re-educated myself many years ago, I took the time to learn who’s on ‘our side’ and who’s NOT.
      Welcome to this website, JA. Next time, get your FACTS straight. So far, the only ultraliberal progressive response on this topic is YOURS.

        CM, do you know any union members who are being screwed out of their healthcare because they aren’t expected to live much longer? Did you know that unions are notorious for having insufficient pension funds? If you were a union member for at least 30 years and you were told that in the name of ‘brotherhood’ that your healthcare had to be sacrificed for the the benefit of younger members, could you live with that?
        By the way, many people claim to be ‘moderates’ these days. Two classic examples of moderate scum are Specter and McCain.
        Think, citizen, think. You can defeat your programming – no matter what your programmer claims.

    I have been taking Metformin for over 2 years now. Although during my quarterly blood tests, my doctor has not mentioned any problem in my vitamin B12. Alomg with the Metformin, I also take Actos and Glipizide, which controls my Diabetes very well.

    Can’t be too careful, especially with the HMO’s today. I think that they tend to LACK in an OVERALL care package and “Flush” patience through like cattle going to slaughter. With this in mind, I will not ignore the information in the article and assure you when I go in for my next check up, will mention this article and it’s findings to my doctor and be sure my B12 levels are normal.

    Thanks PLD, foro the info…….
