Are You High or Low?

Nurse checking patient's blood sugar.

You can't judge your blood sugar solely by how you feel.

Have you ever heard someone say that they know how their blood sugar is doing based on how they feel? It's true, our body does send us some "warning signals" if our blood sugar is getting too low or too high, but we don't really know what our blood sugar is unless we check it. Checking blood sugars regularly can help you find patterns that either tell you you're doing well or perhaps need some changes in therapy. Read more about looking for patterns in blood sugar testing here.

Judging what your blood sugar is can also be tricky because many of the symptoms of hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar) are the same.

Quiz yourself. Based on the following symptoms, is blood sugar high or low? Scroll to the bottom to get the answers.


Blurry vision?

Tired or fatigued?

Extreme thirst?






Shaky: symptom of low blood sugar

Blurry vision: could be high or low blood sugar

Tired or fatigued: could be high or low blood sugar

Extreme thirst: symptom of high blood sugar

Hunger: could be high or low blood sugar

Sweating: symptom of low blood sugar

Irritable: symptom of low blood sugar

As you can see, many of the symptoms of high blood sugar and low blood sugar are the same. That's why checking is so important!
