Before meals, the suggested target blood glucose range is 4.0 to 8.0 mmol/L. At 2 hours after meals, the range is 5.0 to 10.0 mmol/L.餐後血糖正常值
The expected values for normal fasting blood glucose concentration are between 70 mg/dL (3.9 mmol/L) and 100 mg/dL (5.6 mmol/L). When fasting blood glucose is between 100 to 125 mg/dL (5.6 to 6.9 mmol/L) changes in lifestyle and monitoring glycemia are recommended.
It typically occurs about two to four hours after a meal. Researchers don't yet know the exact cause. But they think it happens due to a sudden spike and then fall in blood sugar after eating certain foods, especially simple carbohydrate foods like white rice, potatoes, white bread, cake and pastries.
Several hours after dinner, blood glucose level drops leading to decrease in insulin level and rise in glucagon level. Glucagon is responsible for maintaining adequate blood glucose level in fasting condition via activation of metabolic pathways like gluconeogenesis and glycogenolysis in liver.血糖正常值表
● Serious hypoglycemia is generally defined as a blood glucose below 54 mg/dL (3 mmol/L). This level of hypoglycemia should be immediately treated.

After meals: Checking your blood sugar two hours after you start your meal can help you and your provider assess how food affects your blood sugar and if you need to change your insulin or medication doses.

"The carbs found in bananas are broken down into glucose, which enters the bloodstream before heading to cells for energy. Eating a banana will cause blood sugar to increase, but depending on how much you eat, what you pair it with and the ripeness, that's not necessarily a bad thing," says Lorencz.餐 後 2 小時 血糖
