Hi Lori
You said you don't have "any" carbs, but your sugar keeps going up? It is possible that the food you are eating has carbs, but you may not recognize them. Some foods have hidden carbs, and even sugar (which is not always listed a "sugar," either) Labeling nowadays is clearer...but maybe not as clear as we might like. And it isn't only carbs that can elevarte your sugar. Proteins and fats will elevate sugars, but more slowly. The only form of nutrition a cell will accept is glucose, and the body eventually breaks everything into glucose molecules.
And Humalog will spoil and become less affective beyond its expiration date. So make sure to check the label. And one should discard the humalog one month from opening it...but verify that on the label as well (I use a pen...so I'm not 100% sure it is the same with the vials...).
What has your doctor told you about your high sugars? Have you tested for ketones? And if y ou are running high, please be sure to drink lots of water, to flush your kidneys and be sure you aren't getting dehydrated.
Take care, Lori! Hope thing are going better for you, and that some of this helped! HUGS! sheryl
