How often do you or your child take a correction dose of insulin to reduce a high blood sugar?

Poll dates: November 24 - December 2, 2002
Total Votes: 583

The vast majority of those who responded indicated they used correction doses of insulin at least several times per week. While correction doses are meant to adjust blood glucose levels back to the target range, if your basic regimen is properly tuned, you should only have to use them occasionally.

There is growing evidence that the range of blood glucose excursion is just as important as the average blood glucose, reflected by the hemoglobin A1c. Current thinking is that the range of blood glucose values should be less than half the average. For example: it may be better to have blood glucose values that are consistently 150 mg/dl [8.3 mmol/L], rather than those fluctuating from 50-350 mg/dl [2.8-19.4 mmol/L], even though the average of both would be 150 mg/dl [8.3 mmol/L] and yield the same A1c value.

Blood glucose values consistently above target prior to a meal usually indicate that there is not enough basal insulin. Adjustment of insulin pump basal rates long-acting (Lantus [insulin glargine] or Ultrlente) insulin should eliminate this problem. If you are using NPH or Lente for basal insulin, elevated blood glucose levels before breakfast and dinner would indicate a need for adjustment.

Two-hour postprandial blood glucose readings reflect the effectiveness of bolus insulin and the appropriateness of the insulin/carb ratio. If these values are consistently high, an adjustment needs to be made to the number of grams of carb per unit of insulin, and/or if you are pumping, the type of bolus.

To sum up: While it is a good idea to correct those high blood sugars, make sure you are not correcting too often. Fine tuning your overall regimen will help eliminate the "yo-yo effect" you may be seeing and improve overall control.
