People who do not have diabetes typically have fasting plasma blood glucose levels that run under 100 mg/dl.
Your physician will define for you what your target blood glucose should be — identifying a blood glucose target that is as close to normal as possible that you can safely achieve given your overall medical health. In general, high blood glucose, also called 'hyperglycemia', is considered "high" when it is 160 mg/dl or above your individual blood glucose target. Be sure to ask your healthcare provider what he or she thinks is a safe target for you for blood glucose before and after meals.
If your blood glucose runs high for long periods of time, this can pose significant problems for your long-term — increased risk of complications, such as eye disease, kidney disease, heart attacks and strokes and more. High blood glucose can pose health problems in the short-term as well. Your treatment plan may need adjustment if the blood glucose stays over 180 mg/dl for 3 days in a row. It is important to aim to keep your blood glucose under control and treat hyperglycemia when it occurs.

If your answers to the questions are yes, follow these suggestions.
|Causes||Ask These Questions||Take Action|
|Food||Have you increased your portion sizes?
Have you changed your eating habits or food choices?

|Activity||Have you decreased or eliminated your usual activity?
Are you doing too little physical activity?
|Physical activity is key to blood glucose control. Ask your healthcare team about starting a program.|
Have you been taking the prescribed doses?
Do you have "spoiled" insulin?
· Does your insulin look different?
· Was your insulin exposed to very hot or cold temperatures?
· Has your insulin expired?
Take the right dose at the right time. If you have any questions ask a diabetes educator.
Throw away the bottle and open a new bottle.
Check the expiration date on the bottle.
|Monitoring||Is the drop of blood too small?
Are you using the correct technique?
Could your meter be dirty?
Have your strips expired?
Have your strips been exposed to very hot or cold temperatures or not been kept in an airtight, dry, container?
Is your meter calibrated to the current bottle of strips?
