    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.

      11/6/13; 7:20 pm
    • 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.

    I HAVE DIABETES 2. WHEN MY NUMBERS ARE UP I FEEL BUZZY, LIKE A MOTOR RUNNING THRU MY SYSTEM. I GET BREATHY, SPEEDY, AND MY STOMACH ACHES. I FEEL GREY. IT FEELS LIKE A HANGOVER. WHEN I WAS GIVEN STEROIDS FOR MY BACK TROUBLE, MY SUGARS WENT UP TO ALMOST 700! IT TOOK A FEW MONTHS TO GET THEM DOWN. I WILL NOT TAKE STEROIDS AGAIN.

    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.

    If I eat white bread, white rice, or sugary stuff I will get extremely tired. If I go to sleep too soon after eating, it feels like a sleep coma. I will try to wake up but fall right back to sleep and feel loopy. When I can get up, my left eye won’t open and the white of my eye is a deep red.

    I was recently diagnosed Type 2. What everyone has written here is exactly the opposite of how I was feeling before starting on Metformin and I can pretty safely say that I have never in my entire life felt worse than since my blood sugar has been more “in control”. Even when I’ve felt like my blood sugar should be through the floor, the lowest I’ve been is “normal”. Other than some fairly minor peripheral neuropathy and distance vision issues, I felt pretty consistently great. Since cutting back on the carbs and starting on Metformin in the last month, I’ve taken more Tylenol for headaches than I’ve taken in the previous five years combined, my vision has been up and down like a yo-yo with the worst being worse than it ever was before, and I have never been hungrier or less satisfied eating than now.

    Has anyone else had similar experiences?

      There are a few things that might be causing the headaches. When you cut back on carbohydrates, did you also cut out sugary drinks (juice, soda, etc.)? The reason I ask is that cutting out caffeine or lowering it suddenly can cause some godawful headaches, irritability, and a general feeling like you might drop dead at any moment.

      Beyond that, keep a very close eye on your blood sugar. Though you say the lowest you’ve been is within the normal range, it might not be normal for you. Review that with your doctor to make sure you’re comparing your levels to a custom range, not the universal normal. You might be zigzagging even with the medication, which would make you feel terrible.

      I had a very long spell where I felt “normal” until stress brought every potential problem to fruition at once. My body was simply used to operating with a horrendously high A1C (among other weird lab results). It took the complication of afternoon blood pressure spikes, sensitivity to heat, and some neurological concerns to get me to rush back to my meter… where I found a reading of 385. I was shocked because, like you, I felt pretty good up to that point. The A1C reading was a 14. I was surprised I had not had a random organ fail, but that is more to my point: I must have been having super high readings for several months — and longer — and felt fine. I expect my body will be angry with me coming down, but the relief for my organs and the extension of my life once I level out again will be worth it.

      Hi Danny! When your blood sugar levels are getting back to normal as in 80-120, your body which is used to the highs responds rather viciously. You body has become used to being in a hyperglycemic state. That is its “normal”.

      When your blood glucose levels begin to go down, it may take a few months to feel better. This was my experience. I really had to push past feeling unwell, and teach my body what was truly healthy.

    My daugther was recently diagnose t2 she’s 20 years old and works until 9:00 so her dinner is not until after 9:30 or 10 pm. She’s usually tired from works and is in bed by 11 :30 but she has a hard time sleeping through the night and feels sick with stomach pain and chest pain. Any idea why? She’s only on med. not insulin yet.

    I’ve pretty much given up. I can have normal readings, but I come to a point where I can’t afford to refill my insulin prescription, my numbers go up, up, and I get feeling down. For as long as they have had insulin, and how many people use it, it seems criminal that it’s so expensive. I just want to quit everything.

    I have all of the physical symptoms of highs and lows. But my numbers are still in the ‘normal range’. So I am clinically not diabetic. I get gestational diabetes with pregnancies. Does anyone have any experience or info for the ‘normal’ zone diabetic response.

    I feel those exact symptoms! It feels to me like zoning out, like an out of body experience. Like im just floating. Then the tiredness hits. When I have those sugar highs I withdraw, friends don’t understand why I become so quiet or just walk away to sit and put my head down until it passes. Im 23 and I’ve been dealing with it for 5 years but it doesn’t become any easier.

    Hi, I live with PCOS and I have insulin resistance.
    I have high blood glucose, I urinate frequently, I have had times where I had uncontrollable thirst. The eye comments are interesting cause as of late I have really stugguled with my eyes being sensitive. They burn out of no where. I thought it was the grill at work but I’ve had that issue at random. I don’t know if it is this or the sun or what. I can also relate to having shortness or breath with simple taks. I appreciate this site and the comments to read. I didn’t know what I was experiencing was a sugar high or that information about how the sugar in my body works. Now I can explain to my son’s father why I’m alway urinating. I’m about to deploying and eating will be a challenge but I think i will be fine.

    I understand what everyone is saying, I had just found out the other day that my A1C levels are a little elevated and that my blood sugar levels were high as well but my question is will diabeties make your lower back hurt like you’ve been hit by a sluge hammer

    I walk around feeling very bad a lot. Seems like the older I get the worst I feel but on a real note, I don’t do much to make myself better. I alway start on a eating and exercise plan to only stick with it for a short time then I’m back to eating everything. I now realize that I am now 54 years old and I am feeling worst than ever before. I am type 2 but been diabetic for 14 years. I do take Metformin, pills, but I have my brother as an inspiration. He found out about his diabetes when it went up to over 600 and he was hospitalized. He took insulin for a year and a half. Today, he take no insulin or pills and his last A1C only 1 month ago was 6.2 which is good control. What does this mean? Diabetes can be cured. The key is to cure it before it get’s to bad. Well, my brother’s was bad and than God, he still got curred. I believe he is still a diabetic because if he goes back to his old ways, i’m sure it will come back, but he’s been off the insulin and pills for over a year now and have consistently good numbers, 98 before breakfast, numbers like this. Unless you are Type 1, this group has to take insulin, but all you type 2s, we just need to stop the white carbs, fast sugars like candy, cake, white breads, get some exericse, lose weight, watch the alcohol, we all know what to do. Type 2 diabetes is a life sytle disease, we just need to change our live styles like my brother did.
