How much blood sugar is dangerous?

When the blood glucose monitoring value ≥13.9mmol/L, the body fat begins to decompose, producing a small amount of ketone body, and it is necessary to be alert to danger. When the blood glucose monitoring value ≥16.7mmol/L, the insulin effect in the body is very small, the blood glucose can hardly be utilized, the fat is decomposed in large quantities, and the ketone body increases, causing diabetic ketoacidosis. When the blood glucose monitoring value ≥33.3mmol/L, the body is in a hypertonic state, and diabetic hypertonic coma is easy to occur.
