    I agree with all those feelings; especially the desire to sleep it off….though normally that’s not an option.

  2. It makes my whole body feel thicker and really uncomfortable. This goes away once I get below about 240. Of course the thirst and tiredness goes along with all of this.

  3. For me, it’s like a headache without much of a real ache. It feels like it start behind my eyes and radiates outwards. It’s slower processing and easier distraction. And definitely, definitely the wondering WHY and WHAT I did wrong…

  4. It feels like I have sand in my veins.

    This is probably how my brain interprets the sluggishness feeling.

  5. I am asking the same things when I am high. I get upset easily and everything around me annoys me!

  6. The timing on your post is perfect. I made a string of bad food choices on date night last night and literally ran out of insulin in my pump. I felt like the biggest failure all night and kept checking for a downward trend.

    Every high seems to feel different, but my vision is affected every time.

    I was in DKA at diagnosis and one of my biggest fears is ending up back there. It’s unfortunately a great motivator for controlling my numbers.

    I don’t know if there is any relation between hyperventilation and high blood sugar but when I’m ‘high’ I’m usually gasping for breath even while doing simplest of tasks. It feels shit regardless. Frustration, irritation, short fuse, muscular pain and God if I get high whilst PMSing, I literally feel like I’ve entered Dante’s seventh circle.

    You mention going to the gym…. What I’ve read warns that it’s not good to exercise if glucose if above 250. Comments?

    When my bg is high, I don’t have a headache or symptoms mentioned above; the only thing I note is excessive thirst along with generally feeling unwell.

    • I am fine with exercising so long as I don’t have ketones.

    • My experience: when the insulin level is higher than required, exercise will lower BG, otherwise it will raise it. I have never read anything contradicting this — and I have read a lot …

    I just wanted to thank you from a T1 Momma’s perspective, these posts provide me with such great insight. My sweet 5 year old can’t yet explain to us how she feels when she’s high or low-so this helps me get an idea of what she may be feeling! Thanks for sharing!

    I get all those feelings as commented on above and I become extremely hungry and thirsty. Like I have skipped a couple meals and have an unquenchable thirst.
    Thanks for the great post.

    I remember reading somewhere that having a high is like having thick maple syrup slogging its way through the veins in your body and brain. (That image has always stuck with me.) Beside the heaviness and sluggishness, I feel a weird tightness or pressure, as if my skin has become too small for my body, which makes me feel incredibly edgy. I’m always so glad when that feeling goes away!

    your timing is perfect! I just spent the morning battling high BG’s I woke up with… CGM fail. I couldn’t tell whether I had the stomach bug my kids had this weekend because that is how this hyperglycemia feels. Like the flu. Ugh.

    Thank you for posting this. My 3 year old daughter has type 1. She was diagnosed at 20 months. I knew nothing of diabetes when she was diagnosed and did not know anyone with type 1 diabetes. I read your blog and several others for an understanding of the way she might feel as well as a heads up on issues that I will help her to tackle later. Thank you for the wonderful insight as always. God Bless :)

    Thank you for posting this, and the post on “what a low blood sugar feels like”. As the mother of an 8 year old Type 1 Daughter, I am constantly wondering about this. While she has been able to somewhat describe lows, she has not been able to describe highs.

    I have type 2 diabetes and my blood sugars have been all over the charts. I admit I do not always eat well and when I am HIGH, it really doesn’t show much except the eyes. Dry and like a slight burning.

    I am also fighting Lung Cancer and some meds (Steroids) really shoot my blood sugar, off the charts! Into the 300′s! I use the Pen to controlr my regular type 2, “Lantus Solostar”, but when these steroids raise it into the 300′s, I also have another Pen “Humalog” (fast acting insulin), to get it down fast.

    My wife and I are tired of this mess and have started with the new year, new diets that should help enormously! My chart has gotten to look, like the Rocky Mnts…LOL

    I do not check my blood sugar as often as I should, guess I know what to expect and the strips are soooooo expensive! With this cancer and the cost of the Chemo. I’m on a fixed budget here and squeaking by.

    Oh well, I found what I was looking for on here. Than ks for your POSTS!

    I am t1 and was just diagnosed in Sept of 2012. I am 31 years old now and I am still new to this and still trying to figure it out. I appreciate finding all of the comments above. I have often tried to explain to my girlfriend how it feels to be high or low. I agree with all these comments on being high very much. I feel so tired and worn down during the day and just so blah. Sometimes it’s like I have sandbags in my feet. At night time though I notice that if I am really high I can’t even sleep. That is the case right now. I was at 357 earlier this evening and took 10 units of Novolog. Now I am still currently at 317 I just took another 7 units. I am out of my Lantus and have been for over a year now. I don’t have insurance anymore after losing my job and have just solely been relying on my fast acting. This is a terribly stressful disease to have and manage. I get really hot and uncomfortable and just so irritated because it is so high that I can’t sleep some nights. Is anyone else like that?

    Yes, I cannot rest if my blood sugar is high. I’m taking Novolog and Levemir insulins, both very good but very powerful. One screw up and you will struggle thru the day.

    How come, i have controlled my sugar level from 300 to 140 these days but i still feel thirsty all the time, I have controlled it by jogging and climbing; any input on this?

    When my sugar go up any higher then 400 I get really sick, I feel like my whole body just gain like 200 pounds and I walk slow. I get headache sometimes. Lastly I don’t talk, cause somehow it makes me more sick if I talk.
