Your blood sugar numbers are based upon the amount of glucose that you have in your bloodstream at any given time. Complications can occur when your numbers are too high, so it is important that you know the range that your blood sugar numbers should be in.
Test Blood Sugar
You can use a finger-stick test, which can tell you your blood sugar at that exact moment. This test is a little machine that you can buy at any pharmacy. The machine pricks your finger with a small needle, evaluates the blood, and then tells you your blood sugar number.
Times to Test Blood Sugar
You should test your blood sugar at two main times during the day: before meals and before bed. These times are important because it tells your blood sugar should be at certain levels before you go to bed for a long period of time, and before you start to eat and ingest any amount of sugar.
Blood Sugar Before Meals
When testing before any meal, your blood sugar should be between 80-120 mg/dl. Anything higher or lower than these numbers means that you have too much sugar in your blood, or not enough. These numbers are important to test because it determines the amount of sugar that you should or should not ingest when eating the following meal.
Blood Sugar Before Bed
Before going to bed, your blood sugar levels should be at 100-140 mg/dl. Anything higher or lower than these numbers should be treated accordingly before going to bed.
The above numbers for blood sugar are general estimations, so make sure that you talk to your health care provider to determine what numbers your blood sugar should be at -- each person is different, so everyone is going to have a unique range.
