Hyperglycemia vs. Hypoglycemia


(High Blood Glucose)

Hyperglycemia is when the body can’t use insulin properly or has too little insulin. This causes blood glucose to go above target range or higher than 160 mg/dL.


  • High blood glucose 
  • Increased thirst and frequent urination
  • Tiredness, fatigue, and blurred vision
  • Slow healing cuts or sores

 Treating Hyperglycemia

  • Be sure to drink plenty of water. It is recommended that you drink at least 8 glasses each day.
  • Ask yourself what may have caused high blood glucose/low blood glucose, and take action to correct it
  • Try to determine if there is a pattern by checking your blood glucose 

Always consult with your doctor or diabetes educator to review your testing results if you are not sure what to do.

(Low Blood Glucose)

Hypoglycemia is when your blood glucose level is less than 70 mg/dL or your blood glucose level goes below your individual target range.


  • Low blood pressure
  • Shakiness, nervousness, or anxiety
  • Irritability or impatience
  • Fatigue, sleepiness, or weakness

 Treating Hypoglycemia

With Hypoglycemia, consider the 15-15 rule. Eat 15 grams of glucose or simple carbohydrates, then wait 15 minutes and recheck glucose levels. If the level is still low, repeat.

  • Commonly used carbohydrates include: glucose tablets, gel tubes, hard candies, 1 tablespoon of sugar, honey, jelly, or 4 ounces of fruit juice/regular soda.
