    Its been a little while since I last posted here. I am having an ongoing debate, is having blood sugars in the 400's dangerous? While I know that it is not good to have them that high, I am yet to be convinced that numbers in the those levels can kill you.
    What I do know is that this past week my blood sugars did go over 400 and I went to the ER. They kept me overnight trying to get my blood sugar down. But I was in a waiting area for a couple of hours before even being treated and my numbers naturally went down. Then they put me in a room and gave me an IV, etc.
    Another time while being on this forums chat room, I had elevated blood sugars in the high 300's. At the advice of fellow chatters, I called my diabetes Dr. who told me to take extra Glyburide instead.
    So, I am confused, is it really dangerous to be that high or is it in the eye of the beholder instead.
    Thank you for your replies!

    It is dangerous, but not likely acutely dangerous.
    It is possible for it to become accutely dangerous. More than a day in a row can lead to diabetic ketoacidosis, a dangerous and possibly deadly condition. We're talking usually days, but it can happen fast in some.
    The biggest danger is complications, the longer term effects. There is no doubt that continued 400's will result in likely multiple of retinopathy , infection, amputation, nephropathy, heart disease, neuropathy, and possibly more. It is not medium term sustainable.

    For some people, when their blood sugar number is extremely high, they get blurred vision, become extremely dizzy, exhibit drunkenness, faint or show other physical/physiological symptoms that may cause them to be an immediate danger to themselves or others.
