Your blood sugar is low when the numbers are 70 mg/dL or less. Low blood sugar is also called hypoglycemia. Low blood sugar can:
- Make you feel hungry
- Make you sweat
- Cause headaches
- Cause weakness
- Make you feel dizzy or shaky
- Make you feel anxious or cranky
- Cause you to feel confused
- Make your heart feel like it's beating too fast
- Make you look pale
If you notice any of these signs or symptoms, check your blood sugar. If it is low, eat or drink a source of quick sugar -- like 5-6 pieces of hard candy, 3-4 glucose tablets, or 6 ounces of fruit juice or soft drink (not diet). Check your blood sugar again in 15 minutes. If it's not better, eat or drink a source of quick sugar again. When you feel better, have a protein snack like cheese and crackers or half a peanut butter sandwich. Talk with your doctor if you have two or more low blood sugars in one week.
