Ask the Diabetes Educator Archive


I am a 35 yr old female. My family has a history of diabetes, however the history is high blood sugar. Every so often I experience dizziness, fatigue, feel shaky, and start to sweat and feel as though I am about to pass out. I felt like that today and I took my blood pressure which was normal and I bought a blood glucose monitor to check my blood sugar and it read 70. I am not sure what is considered low blood sugar or high blood sugar. Is it different for each person or is there a range? Is this something that I need to monitor each day? I will have this about 3 or 4 times a month. Any information you can give me will greatly be appreciated

You are describing symptoms of hypoglycemia; a blood sugar of 70 in a non-fasting state is low for many people. A fasting blood sugar of 70 is considered "normal" but for some people, it may be too low. One who is truly hypoglycemic will experience the symptoms you describe more often when not eating properly. When one has periodic episodes, as you describe, it may be due to some other condition. It is important for you to seek medical attention, to "rule out" any other causes since there are many medical conditions that can cause what you describe, given that your food choices are appropriate and your blood pressure is normal.
