Is a pre-meal blood glucose level exceeding 15 mmol/L serious?

Generally, a pre-meal blood glucose level exceeding 15 mmol/L is considered severe. Detailed analysis is as follows:

Blood glucose refers to the glucose content in the blood and is the primary energy source for the body's cells. The body uses hormonal regulation to maintain blood glucose levels within a relatively stable range. Under normal circumstances, the normal range for pre-meal blood glucose is generally between 3.9 and 6.1 mmol/L.

A pre-meal blood glucose level exceeding 15 mmol/L significantly surpasses the normal fasting blood glucose range in healthy individuals. If left untreated, hyperglycemia may lead to acute complications such as diabetic ketoacidosis and hyperglycemic hyperosmolar state, which can be life-threatening. Additionally, prolonged high blood glucose levels may increase the risk of chronic complications, such as cardiovascular disease, kidney disease, retinopathy, and neuropathy. It is recommended to visit the endocrinology or emergency department at a hospital promptly for comprehensive examination and evaluation.

In daily life, it is advisable to limit the intake of high-sugar and high-fat foods, engage in regular aerobic exercise, quit smoking and alcohol consumption, and monitor blood glucose levels regularly to maintain overall health.
