I've been noticing I've been hungrier than usual lately, and while I do take my insulin before I eat, I noticed just now when I took my sugar that it was 368, and it said "ketones?" at the top. I took insulin for it to go down, but it's
still at 310 right now. It's bothering me a lot, the idea of my sugar being this high, because I wanted to work out today but I heard it's bad if you might have ketones. And I'm in college taking classes, I can't miss more than a specific number of classes for any reason or else I fail, so staying at the hospital can't happen. I haven't been too thirsty, or going to the bathroom a lot, just hungrier than usual. I don't understand why it's so high though, if I'm taking my insulin before my meals and trying to keep a healthy diet, although high in protein. Anyone have any ideas?

Regarding the issue of ketones and exercise see this from the Joslyn center ~

I am wondering, if you are not having good results from your insulin injections, perhaps your insulin is past its useful life. Check the vial for the date when it expires. And whenever you start a new vial, write down when you started using from it. Generally speaking the insulin is past its useful life after 28 days of being opened.

To get the ketones the sugars have to be high for a couple of days. I too have have some off sugar. They just happen sometimes. No matter what you do, even when you do everything tight, the sugars go high. They happen sometimes. Everything people have said is correct, check for infections, stress etc. However, even when those thing are fine, you will have an occasional day or two where the sugars just don't make any sense. I hate those days most of all. Once I dial in my glucose levels I am fine. A few other note, check your insulin. I have had high day then I changed my insulin bottle and things went back to normal. If you are on a pump change your set and insulin.

You could do one thing. If u feel hungrier than ever before and if u think u may eat more then just increase yr insulin dose by 2 points. This may get ur sugar in control. Whenever I eat outside due to extra calories in my food i too found my sugar high then my doc gave this advice and it works :-)

Unless instructed by a Dr, as you had been, altering one's insulin dose is not a good thing to suggest to someone else. That is best done by their Dr.

Also to inject one's insulin before eating is also inviting a hypo reaction as one may not eat at the apporopriate time.

God's best to you

There could be some reasons such as it being close to that time of the month. My numbers were always wacky then and I craved every carb in the world as well.
There could be an internal infection going on that you may not know about or feel. That can cause numbers to rise. Even somethings like the start of a cold can cause issues.
Perhaps your insulin is not good. Check your expiration date and make sure you are storing and administering it the way you need to.

You mentioned you are in college, is it exam time or another stress that could be taking them higher? Are you taking any new medication (or even a round of prednisone)? Have you been sick? There are a ton of things that can spike sugar levels and it may take some detective work to figure it out.

I'll echo what everyone else has said, start with the basics, how is your carb counting, IC ratio, correction…maybe you have an infection, cold, rotten tooth…seriously look into a pump.
And I might get some disagreements, but when I've had ketones, I pound the ice water and the treadmill.

There could be alot of reasons but for sure talk to your doc to see what's going on. What type of insulin are you on? Hope your #'s get back down.

Have you been under a lot of stress? We all have some amount,but I am talking about the high level kind.. I have had similar levels just this week.. Mine was coupled with a small reward meal.. I think the combo of stress and a bit too many carbs brought it up.. It did resolve in a few hrs.

Is your blood sugar staying high for more than a few hours? I have found just as Type1Lou has said that it can take a day or two for blood sugar to balance out, but if you have given insulin to correct it then it should start to come down. If it isn't coming down then you should talk to your doctor and find out why.

I find when my BG spikes in the high 200's and more, it takes quite a while (24 to 36 hours) to get it back into the normal ranges…not like treating the low BG's where I get a pretty rapid turn-around. Are you using a sliding scale (given to you by your doctor) to calculate your boluses? Hopefully, you are calculating your boluses by using a carb to insulin ratio that has been worked out for you by your doctor. Carbs are the primary reason for elevated BG's but stress and illness/infection can also be factors. Also, are you rotating your injection sites? If you continually inject in the same areas, your insulin may not be absorbed as well and cause spikes. I was on MDI (Multiple daily Injections) until 2011 when I started pumping and am now kicking myself for having resisted a pump for so long. You may wish to pursue pumping as an option.

You might think that I'm being too basic, but getting back to basics just might be the key to unlocking your delemma.
Have you discussed your high blood glucose levels with your doctor? If it was me, that is the first thing I would do, without hesitation. Make sure you wash your hands before testing with your meter. I have actually had readings that were over 100 points to high and inaccurate as a result. Are you absolutely sure that you are eating correctly, and making good healthy, balanced food choices. It's always a good idea to see a registered dietician, especially if they specialize in diabetes.
After all, it's your life and health that's at risk.
There are three important factors that come to mind and stand out, as I read your post. A proper food plan, the correct amount of insulin relative to your food intake ( especially carb levels ), and exercise ( including your activity level in general). Frequently, getting these three factors into balance, can make a substantial difference for many. Of course, there are many other things to consider, when managing diabetes, but the three that I have mentioned can make the difference, and lead to successful diabetes mgmt. All it takes is to not do one of these three correctly, and chances are you'll have a problem getting your glucose under control.
Take a good hard look, speak with professionals and experts for guidance, and don't waste any time. With the correct guidance and knowledge, you can get and keep your blood glucose within healthy range.
