Symptoms of High or Low Blood Sugar
Being aware of the symptoms of high or low blood sugar can help you understand your test results and decide
what to do if they seem unusual. Here are the most common symptoms.
High blood sugar (hyperglycemia): fatigue, increased appetite or thirst, frequent urination, blurred vision,
headache, or general aching.
Low blood sugar (hypoglycemia): sweating, trembling, blurred vision, rapid heartbeat, tingling or numbness
around mouth or fingertips.
If you are experiencing any of these symptoms, test your blood sugar. If your blood sugar result is
displayed as LO or HI, and you have symptoms of low or high blood sugar, follow your doctor’s
instructions, or contact your doctor immediately. If your blood sugar result does not match how you
feel, follow the steps under “Unusual Test Results.”
Unusual Test Results
If your blood sugar result doesn’t match the way you feel, follow these steps:
1. Run a control test (see Chapter 2, “Control Testing”).
2. Repeat a blood sugar test (see Chapter 3, “Testing Your Blood Sugar”).
3. If your blood sugar results still don’t reflect the way you feel, follow your doctor’s instructions or call your
doctor immediately.
Note: Always follow your doctor’s instructions. For example, if your doctor has advised you to immediately
treat a low blood sugar result (such as by eating something), then do that first.
