Understanding Your Blood Glucose Readings

Testing your blood sugar at home—also called self-monitoring of blood glucose (SMBG)—is the single best tool you have to manage your type 1 or type 2 diabetes on a daily basis. Why? Testing helps you: 1. Catch and treat any dangerous blood sugar highs or lows. 2. Understand how your blood sugar rises in reaction to certain foods. 3. Recognize how exercise changes your blood sugar levels. 4. Determine if your diabetes medications are working. 5. Calculate your insulin dose for meals (if you have been prescribed a rapid-acting insulin). By using the information from regular blood sugar testing, you can make sure your efforts to eat right, exercise, and take your medications are paying off. And studies show that keeping your blood sugar under control is the best way to reduce your risk of long-term diabetes complications like kidney damage and heart and eye disease. What is a healthy blood sugar level? Everyone has unique blood sugar targets based on their individual medical history, age, and lifestyle needs.

    A work colleague was taken ill at work on Friday and taken off to hospital by his dad.
    He is still in, apparently his heart rate was high, but he has also been diagnosed as type 2 diabetes, his blood sugar upon admission was apparently 22.
    The mrs has type 2 also, but I have never seen her this high.
    The chap at works speech got progressively worse over the preceding couple of days ( has does not have the best speech, so we did not notice initially) my thoughts when he was taken away was possibly a stroke (although we did the basic checks and all seemed fine)
    How dangerous is 22?

    22 as a one off is not dangerously high but if it remained high there is the risk of a diabetic coma (diabetic ketoacidosis) which I life threatening.
    I suspect if your colleague didn't know they were diabetic then they have probably been running high for a while and that's why they were experiencing the symptoms you describe.

    I suspect if your colleague didn't know they were diabetic then they have probably been running high for a while and that's why they were experiencing the symptoms you describe. Its dangerous but not life threatening - DKA takes quite a while to set in, when my brother had a random blood glucose of 22, I rushed him into A&E, 15mins later, he was on an insulin drip.
