Symptoms of High or Low Blood Glucose
Being aware of the symptoms of high or low blood glucose can help you understand your test results and
decide what to do if they seem unusual. Here are some common symptoms:
High blood glucose (hyperglycemia): Symptoms of hyperglycemia may include, but are not limited to,
increased thirst, frequent urination, blurred vision, drowsiness, and/or unexplained weight loss.
Low blood glucose (hypoglycemia): Symptoms of hypoglycemia may include, but are not limited to, anxiety,
shakiness, sweating, headache, increased hunger, dizziness, pale skin color, sudden change in mood or
irritability, fatigue, difficulty concentrating, clumsiness, palpitations, and/or confusion.
If you are experiencing any of these symptoms, or other unusual symptoms, test your blood glucose.
If your blood glucose result is displayed as LO or HI and you have symptoms of low or high blood
glucose, follow your healthcare professional's instructions or contact your healthcare professional
immediately. If your blood glucose result does not match how you feel, follow the steps in Chapter 3,
"Unusual Test Results."
