[Science of Diabetes] One of the most common questions asked by people with diabetes is: “What are normal blood sugar levels?” Unfortunately, there’s no simple answer to this question, because it depends on how you define normal. It’s like deciding when someone is rich or poor, tall or short, thin or fat, or young or old. Most people would agree that a very skinny person was thin and a very fat person was fat. But how about the sizes in between? When does underweight become normal and when does normal become overweight? It’s all a matter of definitions and cutoff points set by one group or another. The definitions of normal, prediabetes, and diabetes are usually made by august committees of diabetes experts, and they change from time to time. For example, not too long ago, it was decided that you’re diabetic if your fasting BG level is 126 mg/dL [to convert to mMol/L, divide by 18] or higher, instead of the previous cutoff of 140. There are some guidelines about ...
My efforts to manage my blood sugar and be a good parent collided last night. Here's what happened:
First of all, some background information. Yesterday Sienna received her six month immunizations. The check-up went well; she's growing perfectly and developing normally. Getting shots always puts her in a little bit of a funk. So, by around 7:00 p.m. she was getting fussy and tired. I'd just enjoyed a delicious bran muffin after going for a walk with my mom and Sienna.
I knew my blood sugar was on the high side, so I tested in anticipation of dinner. My blood sugar was 233 mg/dl. Oops! I bolused 2 ½ units of insulin as we were planning a low carb dinner of homemade cheeseburgers. Dennis and I attempted to feed Sienna some milk and then some oatmeal, both of which she mostly refused. She was getting more tired and fussy by the minute.
"Okay," I announced. "Let's just get her in bed and then make our dinner."
The memory of the recent bolus hit me, ...
So you don’t have diabetes. Should you still be worried about having an elevated risk of Alzheimer’s disease? A new study out of the University of Arizona suggests that you could still have reason for concern.
The study looked at whether elevated blood sugar levels in people who do not have diabetes might indicate higher risk for developing Alzheimer’s disease. The link between diabetes and Alzheimer’s disease already has been studied.
The researchers used a specific type of positron electron tomography (PET) imaging technique to produce three-dimension images of metabolic activity in the brain. As part of the study, researchers used the PET imaging to look at fasting serum glucose (blood sugar) levels that study participants experienced after several hours of not eating.
The researchers analyzed data on 124 adults who were cognitively normal and did not have diabetes. Each of these participants had a family history of Alzheimer’s disease. They ranged in ...
