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 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 “Control Testing”).
2. Repeat a blood sugar test (see “Testing Your Blood Sugar”).
3. If your blood sugar results still don’t reflect the way you feel, call your doctor immediately.
