    Blog: Top 10 diabetes myths

    By Nancy Klobassa Davidson, R.N., and Peggy Moreland, R.N.

This blog is the first in a two-part series in which we discuss the top 10 diabetes myths.

Hello, bloggers. I've been looking at articles from a number of popular diabetes magazines and other resources about diabetes myths. Each one seems to have its own list of the top five or 10 diabetes myths.

I decided to develop my own list of the top 10 diabetes myths that I've heard as a diabetes educator at the Mayo Clinic in Rochester, Minn. I'll reveal five this week, five next week.

Here goes (drum roll).

I have borderline diabetes or just a touch of diabetes.

Either you have it or you don't. Two fasting blood sugar readings over 126 milligrams per deciliter (mg/dL) or 7 millimoles per liter (mmol/L); a random blood glucose over 200 mg/dL (11.1 mmol/L); or an A1C of 6.5 percent or higher are all considered diabetes.

I don't know why I got diabetes, I never eat sweets.

Just about everything you eat is converted into glucose — sugar — so for most people with type 2 diabetes, what you eat is not as important as how much you eat. When you overeat, you're adding extra calories your body doesn't need for energy, so your body will convert these extra calories into fat. Being overweight is a predisposing factor for developing diabetes. 

I can't eat carbohydrates; it makes my blood sugars go high.

Of course they do — even people who don't have diabetes will see an elevation in their blood glucose after eating. Carbohydrates should be approximately 50 percent of your daily food intake each day. Carbohydrates are your fuel, without them you will have little energy.

If I have to go on insulin; that must mean my diabetes is really bad.

You know, insulin has gotten a bad rap through the years. It's the blood glucose control that determines whether you go on insulin; if diet alone or diet along with oral or noninsulin-injectable diabetes medication(s) is not controlling the blood glucose, insulin is necessary.

Insulin causes complications of diabetes.

Again, insulin has gotten a bad rap. Insulin is a natural hormone and is probably one of the safest medications around. Insulin helps control the blood glucose, which in turn slows down or prevents diabetes complications.

Your thoughts? What are some of the diabetes myths you have come across?

Have a great week,

Nancy

    I have Type 2 Diabetes, am not overweight and eat well to control my blood sugar. I'm not on any medication. I've found that many people believe eating any dessert is forbidden. I've explained what I eat, greatly effects my blood sugar. Pizza and pasta are the culprits for me. I can eat dessert, but it's best eaten with a meal. I've also heard that a diabetic should never drink alcohol. I have a glass of wine, a scotch, or a beer now and then and don't think it's proved detrimental to controlling my blood sugar. What do you think?

    I shiver sometimes even when it is hot out and I get blurred vision when I eat sweet, or even worse, I get sick to my stomach. and the room just goes round. I oven over urinate, even when I'm not taking diaurtics. What must be the problem.

    Maureen: Good question! Diabetes Type 1 used to be called Juvenile Diabetes as it was once thought to occur only in those below the age of 20. In fact, type 1 can occur at any age. On the other hand, type 2 diabetes which used to be called "adult onset diabetes" is occurring more and more at a younger age, even children.

    NANCY I FOIND THIS INFORMATION TO BE VERY INTERESTING. I was just diagnosed with type 1 diabetes and insulin dependent. I am 50 years old and not overweight. I'M ASSUMING I ACQUIRED IT FRIM MY MOM EHO WAS DIABETIC ALSO. MY QUESTION IS , I THOIGHT TYPE 1 WAS JUVENILE DIABETES?

    I WAS DIAGNOSED WITH TYPE 2 11 YEARS AGO, AND FIRST I WAS ONLY ON METFORMIN AND NOW METFORMIN AND INSULIN. WHY DO DIABETICS GET SUGAR CRAVINGS? BEFORE I WAS DIAGNOSED, I NEVER ATE AS MUCH SUGAR AS I DO NOW. I MENTIONED THIS TO MY DOCTOR AND HE JUST SHRUGGED THIS OFF. I TALKED WITH SEVERAL PEOPLE WHO ALSO HAVE TYPE 2 DIABETES, AND THEY SAY THE SAME THING. IS IT THE MEDICINE CAUSING THE INCREASE URGE FOR SUGAR?

    Add my voice to all the others who take exception to your advice to make carbohydrates 50% of your diet. This is extremely poor advice. Please read up on Dr Bernstein, Gary Taubes, or this site: http://www.phlaunt.com/diabetes/. These are not quacks, but people with intelligent, well-researched information, that is gradually becoming more and more accepted.

    I was diagnosed with Type 2 diabetes in Dec.2010. My BG readings had been high during repeated admissions following open heart surgery in Jan.,2010,followed by a number of complications requiring readmissions and a significant amount of steroid administration. The decision by the PCP was education, diet control, exercise and monitoring of my BG. My reading is most generally highest in the early morning--Up to 200 --so I was told to increase my bedtime snack. That helps the BG but also increases my weight which is NOT good for my cardiac status. The rest of the day readings are in the 150-180range. Last HA1C was 6.6. I am not on any meds. For diabetes. Any suggestions for consideration? thanks!

    Two years ago, when I was diagnosed, I went on a low carb diet (rarely over 50 g per day), and greatly increased my intake of fats. All my lipid numbers went from out of range to excellent within ninety days. I gradually lost fifty pounds without trying. I've been able to control my D2 with metformin alone. If I were to eat 50% of my diet in carbs, low- or high glycemic, my blood glucose would go through the roof. I'd have to be on insulin, with its attendant problems of insulinemia, weight gain, and, worst of all, the ongoing danger of hypoglycemia, which can be fatal, not to mention all the muss and fuss of constant testing, carrying insulin around with me, and so on. Fortunately, I never have to worry about any of these dangers. I haven't seen a number below 80 or over 140 in a year. I regard my life as unaffected by the disease. Based upon my reading and the advice of my endocrinologist, the information in this blog entry seems hopelessly outdated and incorrect. Were I to follow it, it would also be dangerous. At the very least, these ladies should read the Bernstein book, some of more accurate online material (bloodsugar101.com, for example) and the studies of the last twenty years and bring themselves up to date.

    Carbohydrates should be 50% of your diet? You obviously have no idea what you're talking about! Go read "Good Calories, Bad Calories" by Gary Taubes and get a clue.

    What is the recomendation for over the counter vitamin suppliments for Diabetes Type 2. My Doctor is advising 5000 units of D...triple fish oil...no calcium+vitamin D. Metformin 4 a day...Actos...Plus my regular Multi Vitamin...Zero Carbs...One fruit a day...no vegtables except lettuce or raw... I just was diagnosed in Feb...shouldm't I at least give diet and exercise a chance??? I am swimming an hour a day and/or walking an hour a day...My blood levels are 113, in the am...and will be starting a support group, where I am going to find a different doctor. He seems to be just wanting to give pills and more pills. What is the thought on this pill taking approach???

    @Tim Okay, not eveyone who has type 2 diabetes "eats themselves into it". Some people have diseases that make them prone to getting it, such as myself. Thyroid conditions or P.C.O.S. (Polycystic ovarian syndrome) can make people gain weight and increase the chance of getting Type 2 Diabetes.

    Nancy ~~ You indicated in your discussion of Myth #3 that carbohydrates should be approximately 50 percent of one's daily food intake each day. How is this to be measured? Grams (or ounces) of non-carb food versus grams (or ounces) of carb food? Or versus carb grams? I would like to be comparing apples with apples. Thank you (and thanks for this useful feature!)

    I was the caregiver to my mother that began having diabetic symptoms due to an onslaught of medications. She was relatively fair in weight ~ not overweight, was active, but had sever autoimmune diseases. Granted her situations of health demanded such medicinals, we learned that carbohydrates, proteins, fats, and certain vegetations were key in maintaining a healthy blood sugar level. Upon a time in which I was carrying my first child, I was diagnosed with Gestational Diabetes. Granted it isn't a permanent diabetes but it is treated as such and a balanced diet in a healthy wave or peak levels is key. I was hardly over-weight when diagnosed...even with being expectant. You also CAN be border lined diabetic! It's called hypoglycemia and hyperglycemia. These types of glucose/pancreatic disorders are pre-cursors for the building of more damage ~ Type 1 Diabetes or Type 2 Diabetes depending on the particular body at hand. Please, unless you are fully educated on the subject of diabetes, refrain from "myths" as someone may not take the time to read the educated comments.

    I have type 2 diabetes. I am not over weight, i've been active my hole life; a cheerleader in high school and the Navy after that. I have been reading, and it seems like people are saying its my fault for having diabetes... How???

    So, I've been told that I am "pre-diabetic". It appears from your blog that this is just a nice way of saying that I AM diabetic? I have regular hemoglobin Ac! and fasting glucose tests. They are 'slightly' elevated. What do you think? Should I just be told I am diabetic or what? I prefer a straight answer!

    I agree with the comment that type 1 should be called something different. Being diagnosed at 33 one year ago was awesome, but please don't group me together with type 2's. I'm not fat, have never been fat, and I didn't eat myself into the disease. I was the only type 1 in my diabetes 101 classes at the hospital. The other 20 type 2 people were all overweight. If you are type 1 get a pump. Best technology ever invented!

    Having had no insurance for the past four years, my diet has consisted for the most part of leafy green vegetables and lean meat. I can now not afford to even purchase test strips or meters. However, I fully believe that going off of the insulin stimulating medications, as well as keeping a close eye on the amount and type of carbohydrates that I consume, has been the dietary regimen that has allowed me to shovel off the extra 45 pounds of body fat that had made me feel totally miserable in the past. I am of the belief that keeping my insulin level low has helped me cut down on the amount of fat that my body wants to retain. I hope that I am not the only person who has been aided by going off of the insulin-stimulating drug regimen. There must be a significant correlation between the amount of insulin in the body and the body's ability to burn off, rather than store its extra blubber. I no longer feel the low blood sugar shakes, and I seem to never fall asleep due to excessive blood sugar levels. I can only surmise that there is a great and powerful God who makes it available for me to disregard the medicines and progress in health. May He bless you all!
