Preventing High Blood Sugars

How To Prevent Highs

For better blood sugars and fewer lows, test often and review your readings once a week for patterns of lows or highs, or both. Identify these problems, then consider their causes and how to correct them. Make one change at a time and correct lows first. If you need any advice at all about how to correct a problem, be sure to call your physician or nurse educator right away. Do not let control problems linger as they usually turn into larger problems.

When trying to prevent low blood sugars, it helps to understand their most common causes. The table below outlines the most common causes. If your are currently experiencing either frequent or severe reactions, look carefully at this list to see what is causing them.
