Diabetes Testing Questions
Answered by Tamara Kurtis Randall, MS, RD, LD

Q. Why can't I test anywhere but on my fingertips? I know I can get another machine that lets you test anywhere, but I can't afford that right now. What's wrong with using my machine somewhere else?

A. Older meters can only measure the glucose in a sample from your fingertip because the amount of glucose in your blood varies in different areas of your body.

Check the ads in the Sunday paper for sales on the newer meters. Often times they're offered at very low cost or even free with the purchase of a box of strips.

Q. I have Diabetes and I don't exactly understand it. For example, if I test high, have I done damage to my body or does it have to be high a lot?

A. Anytime your blood glucose (sugar) is high, there is the potential for damage to your tissues including your eyes, heart, kidneys, and nerves. The problem is that your blood glucose goes up and down all day long depending on what you've eaten, your activity level and if you take any insulin or oral medications.

The more of your readings that fall in the normal range (80-120 mg/dl), the more likely you are to avoid the long-term complications.

Q. Thank you for taking my question. I am Diabetic and have been for a long time. I test regularly and take my pills faithfully. I have not changed my routine in any way that I can think of. Yet my numbers lately have been getting higher and higher.

If I am following the plan, shouldn't they stay the same. Any idea what I could be doing wrong. I am afraid if I tell the Doctor he will suggest insulin and I don't think I could give myself a shot. Please help.

A. You're probably not doing anything wrong. Over time, your body changes and the pills you're taking now may no longer be as effective as they once were. The important thing is to keep your blood glucose under control.

It is possible that there is a different medication your physician can prescribe, but if the recommendation is insulin - it's not the end of the world. Learning to give yourself an insulin injection is not nearly as bad as the potential complications associated with uncontrolled blood glucose.

Q. I had the flu about 6 weeks ago and my sugar has never been the same since. Is this normal? Will it go back down again?

A. An illness causes your glucose to rise, but it should return to normal when you are feeling better. You should contact your physician if your glucose has not returned to normal.
