Introduction
The normal blood glucose level after lunch should be below 6.7–9.4 mmol/L. Normal fasting blood glucose levels range from 3.9 to 6.1 mmol/L. One hour after eating lunch, the normal blood glucose level should be between 6.7 and 9.4 mmol/L; two hours after the meal, blood glucose should be less than or equal to 7.9 mmol/L; and by three hours, it should have returned to normal.
Under normal circumstances, the blood glucose level after lunch should be below 6.7–9.4 mmol/L. The detailed analysis is as follows:
Fasting blood glucose should normally range between 3.9 and 6.1 mmol/L. One hour after lunch, blood glucose should remain within 6.7–9.4 mmol/L; two hours after the meal, it should be less than or equal to 7.9 mmol/L; and by three hours post-meal, it should have returned to baseline levels. If blood glucose remains between 7.9 and 10.1 mmol/L, this indicates abnormal blood sugar levels. When blood glucose is higher than or equal to 11.1 mmol/L, diabetes should be suspected. Patients should pay close attention to symptoms such as dry mouth, excessive thirst, and frequent urination, and seek comprehensive medical evaluation at a hospital promptly.
When blood glucose abnormalities or diabetes are detected, patients need to control daily sugar intake and modify their dietary habits by avoiding spicy, stimulating, high-sugar, and high-fat foods. Regular physical activity should be incorporated to promote insulin secretion and help maintain stable blood glucose levels. If blood glucose levels continue to rise and cannot be controlled through lifestyle adjustments, patients should seek timely medical treatment and, under a doctor’s guidance, may require antihyperglycemic medications.
