How does blood sugar get as high 836?

A blood sugar reading as high as 836 is highly unlikely. The range for normal blood sugar levels is between 70 and 110 milligrams per deciliter (mg/dL). Anything higher than 140 mg/dL is considered high blood sugar.

In cases of severe hyperglycemia, which is a condition where blood sugar levels are extremely high, the blood sugar level may reach up to 500-600 mg/dL. However, a reading as high as 836 mg/dL is exceptionally rare and would require immediate medical attention.

If you or someone you know is experiencing blood sugar levels that high, it's crucial to seek emergency medical care without delay. It could indicate a severe underlying medical condition that needs immediate evaluation and treatment.
