Have You Noticed This About Your Diabetes?

Yawning With Low Blood Sugar

Yawning With Low Blood Sugar

| Nov 17, 2012

In this new column, "Have You Noticed This About Your Diabetes?" readers send in observations and questions, and, in response, other readers share similar and not-so-similar experiences by posting in the "Comments" section.

The following is Christie's question about the association of hypoglycemia with yawning. 

"Years ago, I noticed a sign whenever my blood sugars are too low and occasionally when they are too high: yawning! It has been as accurate as can be. Often if I continually yawn, my husband will ask me to go and check my blood sugar. More than 98 percent of the time, it is as accurate a predictor as shaking or sweating, and it usually happens much sooner. Has anyone else ever noticed this symptom? People think I'm crazy when I bring up this topic!"

If you have a question that you would like answered by a member of our advisory board or shared with our readers, please email editor@diabeteshealth.com, and write your question in the subject line.

I haven't noticed that yawning may indicate hypoglycaemia in my child but I will be watching for it now!! Thank you for sharing.

No yawning signs but if I get a numb tongue, I know I am in trouble!

Makes sense to me, I get tired when I have high or low BS, so yawning would be an appropriate action!

I have had Type 1 for 26 years. In the past I used to have a hard time focussing when my blood sugar was low, but during the past three months, when it was low I got extremely sleepy.

I totally agree...it doesn't always happen, but when I am yawning alot, my husband will also tell me to go check my blood sugar and usually he's right.

Over ten years ago one of my patients noticed the same thing. This was a lady with hypoglycemia unawareness, until we made this correlation. She lived alone and I was very worried about that. Discovering the yawn sign may have been a lifesaver for her. She knew that, even if someone yawned in her face, if she yawned too it was absolutely imperative that she check her blood sugar!

I have had Type 1 diabetes for 22 years,several years ago I realized that I yawn when going low. It is a consistant "tell" for me and is helpful in recognizing I am going low before any other symtoms kick in

I have had the same experience.

Yes I have noticed the same thing. Its continus yawning.

yes I agree certainly sometimes yawning can be just a sign of being tired but it is also a good sign of being low

I have been a type 1 diabetic for over 27 years. Yep, I definitely have noticed that usually when I yawn more than 2 consecutive times it is a sign my blood sugar is low.

Very definitely, yawning is a sign of a low BG. My husband discovered this in me, many years ago. Living with type 1 for over 50 years.

Yes. This always happens to me during lows. I'm guessing it's a body's reaction to get more oxygen as the low blood sugar is effecting other functions. It's a legitimate thing to be conscious of.
