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 the most
common symptoms:
High blood glucose (hyperglycemia): fatigue, increased appetite or thirst, frequent
urination, blurred vision, headache, or general aching.
Low blood glucose (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
glucose. If your blood glucose result is displayed as LO or HI,
contact your healthcare professional immediately.
