What is the dangerous glusoce range for diabetes?

Diabetes: There is no one dangerous blood glucose reading per se, but it's the sustained high readings seen in uncontrolled diabetes that lead to the very serious condition of dehydration, diabetic acidosis and subsequent diabetic coma. A single very high level, if properly treated promptly, won't result in those aforementioned complications. However the diabetes would be poorly controlled if high readings

Agree with Dr C: Two things also possible are 1.People with type 2are at risk for hyperosmolar hyperglycemic nonketotic syndrome It is rare in people with type 1 diabetes.and is an emergency caused by very high blood sugar, often over 600 mg/dL. 2.Diabetic ketoacidosis is a serious problem of type 1 and,less of type 2 diabetes and happens whenblood sugar is very high and acidic substances called ketones

A1C: You may wish to monitor your A1c level for long term control of your diabetes. Agree with the comments by Dr. C.
