Is a 2-hour postprandial blood glucose level of 13.5 mmol/L severe?

Generally speaking, whether a blood glucose level of 13.5 mmol/L two hours after a meal is serious depends on the individual patient's condition. The specific analysis is as follows:

1. Not serious

If the blood glucose level of 13.5 mmol/L two hours after a meal occurs only once, and the individual does not have diabetes or symptoms such as excessive thirst, frequent urination, or dry mouth, it is usually not serious. This may be due to unhealthy eating habits causing a temporary spike in blood glucose, which generally resolves gradually after improving diet.

2. Serious

If the patient already has diabetes, this reading may indicate poor blood glucose control and significant fluctuations in blood sugar levels, which is generally considered serious. Without timely management, acute hyperglycemic complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic state may occur.

Diabetic patients can take glucose-lowering medications under a doctor's guidance. Commonly used medications include metformin sustained-release tablets, acarbose tablets, and glibenclamide tablets.
