Do you or a loved one have diabetes? Are you yourself or do you know someone that is hypoglycemic (low blood sugar levels)? Here is how to treat it:

[edit] Steps

Test your blood with a blood glucose meter using a lancet device and testing strips as directed by the manufacturer.
Wait for the reading to occur on meter.
If the number is below a normal range (typically 70-120) then proceed to step 4.
Consume 15 fast-acting carbs (simple sugars). (These include things like regular soda, fruit juice, glucose tablets, candy, cake icing, etc.)
Check your blood glucose again in 15 minutes using the same procedure as in steps 1 and 2.
If your reading is still under normal range, repeat steps 4 and 5 until your blood glucose rises to normal range.
Once your blood glucose is in normal range, and your next meal is not for another hour or so, eat a 15-30 carb snack.

[edit] Tips

Make sure your meter and meter supplies are accurate, have not expired and are still of good use.
While your blood glucose is low, try not to move around a lot as this could cause your blood glucose to drop lower.
Ask someone who is close by to come and stay with you for a few minutes until your blood glucose is normal. This will reduce risk of injury.
Remember the rule of 15; eat 15 carbs - check blood glucose in 15 minutes
The state of low blood sugar is also referred to as low blood glucose, low blood count, and hypoglycemia.

Check with your doctor or endo for an evaluation of your normal blood glucose levels.
Do not give solid or liquid foods, glucose tablets, or cake frosting of any kind to someone who is allergic or unconscious.
If unconscious immediately call 911, an ambulance, or doctor. Administer glucagon if it is available.
