High Blood Sugar Symptoms

If you’ve had diabetes for any length of time at all, you’ve probably seen lists of the signs and symptoms of high blood glucose dozens of times. Doctors and diabetes educators hand them out. Hundreds of websites reprint them. Most diabetes books list them. You likely know some of the items on the list by heart: thirst, frequent urination, blurry vision, slow healing of cuts, and more. But have you ever stopped to wonder why these symptoms occur? How does high blood glucose cause frequent urination, make your vision go blurry, or cause all of those other things to happen? Here are some answers to explain what’s going on in your body when you have high blood glucose.

    Highest Blood Sugar Reading?

    I am just curious as to how badly other people's blood sugar levels have gotten. I've had mine register at over 600 at times. In fact, my meter wouldn't even give me an exact reading. It just said "HI". Scary. So, what is the highest your blood glucose level has ever gotten, and did you require any medical attention?

    After a ERCP my sugar was normal around 104 within the next blood work I had was 2 weeks later it was 1340. They told me to go to a ER the ER was amazed I was walking and talking the only effect I felt was I could not see 2ft in front of me. Now they are saying I am diabetic I'm a little confused how it jumped so high so fast. I can not get answers everyone just tells me I am diabetic and the test that they do would prove that I was diabetic for 3 months because of the 1340 but I am stupid and they will not see my point nor give me answers. They just say that the ERCP did not cause any of this but they really cant explain what did. So now I have to take 4 shots a day and oral medication 2 times a day.
