Could be you're not making as much of your own insulin or could be an unknown infection causing it to go higher than normal. When your body fights off infection it can cause your sugars to raise slightly and when you have an active infection it can cause your sugars to raise a little to a lot depending on how bad the infection is and how your body reacts to that infection. I learned this the hard way..

sometimes it can happen just for the heck of it, just monitor and maybe straighten back out

OK its normal now...
I ate a bit of dry fruits the other day..walnuts...pistachios...almonds etc...
Maybe that has something to d with it. Thankfully its sorted out now and I don't have to increase my oral medicine dosage.

The nuts shouldn't affect it if they were just steamed or "natural" (which is really steamed before canning in most cases).. but the dried fruit could have. I know for me fruit really can shoot my numbers up.. Glad it resolved itself.

I believe that dried fruit was the culprit.

oh yes..............it lasted for two days and now i am back to normal...

wow...........we really need to understand our bodies better

Since everyone is different you just have to do a bit of trial and error to figure out what foods affect your body differently..

Thats true, need to bring more awareness in life...

I have found my blood sugars fluctuate....becuz diabetes has a mind of it's own. I know when I feel a little or a lot off.....it throws my sugars off, but usually they come back into range within a day or two.....sometimes up to a week and I have to just ride it out.
My opinion is to not worry unless it becomes chronic for about 3 weeks. It doesn't hurt to call the doctor if you are concerned before 3 weeks and perhaps they can help you if they feel it is a real problem or not.
I agree that nuts should not be the culprit. However....dried fruit....that's a whole other ballgame. It's a constant game of trial and error to see what and how different foods effect you.
My mom and I are both diabetics and she eats everything and uses portion control (most of the time) and her sugars are under control. However, I can not eat the usual diabetic no no foods (white flour, white rice, pasta, soda, or fried foods.....and ice cream) as I get very sick and unable to function.
It was my birthday yesterday and my friends ordered me a huge birthday dessert at the restaurant.. I had already ate my total carb count and could only stare at this masterpiece. I took two small......REALLY small bites to avoid seeming rude and I still felt ill....had to come home and take a home remedy to get my sugars to come down from two VERY SMALL bites :(

I'm glad to see that your sugars are back in range. Could have been fighting off an infection or sickness of sorts as others have mentioned.
