What is Hypoglycemia Unawareness?


After having diabetes for many years it's possible to experience what's called hypoglycemia unawareness. This is when you do not feel or sense low blood sugar symptoms. Your very first signal of a low can be confusion, twitching of your hands or feet or passing out. At this point you are having a severe low and need help.

The American Diabetes Association suggests that people who have hypoglycemia unawareness or one or more episodes of severe lows within a short period of time raise their blood sugar goals for several weeks. This often helps the symptoms of hypoglycemia return and can help avoid further severe lows.

If you experience hypoglycemia unawareness or severe lows you should discuss this with your healthcare professional. Both can be better managed with guidance and possibly an adjustment to your treatment plan.

Let others know that they should never try to give you liquid or solid food if you are having a seizure or are unconscious due to severe low blood sugar. This can cause you to choke. After using a hypoglycemia rescue kit, they should immediately seek medical assistance.

Two seizures, multiple black outs, the "I'm fine" at 32, the nauseating 85, and everything in between. That certainly doesn't mean that I'm used to them or that each low doesn't feel like a new and treacherous journey. They still scare me. They still annoy me. And they still overrun my life at times. Since I've hit the gym and the calorie counting on an aggressive...
