What can go wrong?

Sometimes your blood sugar may get too low or too high. If your blood sugar becomes too low it can be very dangerous

To prevent dangerous low blood sugar, here are some important tips:

Check your blood sugar often or use a continuous glucose monitoring device. If you are doing blood glucose monitoring with fingersticks, talk to your doctor about how often and what time of day to create your own schedule.

• Watch out for clues          
• Low blood sugar clues include: irritability, shaky hands, being tired, confusion, blurred vision, heart racing, sweating.
• Usually, blood sugar is TOO LOW if it is less than 70 (mg/dL). Important to keep your fasting blood glucose between 80 - 130 (mg/dL).

Make sure friends and family also know the clues for low blood sugar. When your blood sugar gets too low, you may be too confused to remember what to do. It's important that friends and family know when you need help fixing low blood sugar.

If your blood sugar is less than 70 (mg/dL), OR if you have clues of low blood sugar (see above), take action!

Take action

CONTACT your doctor if low blood sugar becomes a recurring event as your insulin dosage may need to be readjusted.

If you experience the above symptoms and your blood sugar falls below 80 (mg/dL) follow the “Rule of 15.”

- Take 15 grams of carbohydrates
- Wait 15 minutes, recheck glucose
- If blood sugar is still low (< 80 mg/dL), repeat
