Dear Miss Su:
1.
Generally speaking, blood glucose levels gradually rise after meals, peaking around two hours postprandially.
If insulin secretion and action are normal, blood glucose levels should not exceed 140 mg/dL and will then gradually decline.
However, due to the body's metabolic needs and responses, glucagon and other hormones work together to effectively utilize energy stored in glycogen and fat.
Even after fasting for eight hours, blood glucose levels can be maintained around 70-100 mg/dL.
Therefore, pre-bedtime blood glucose levels are rarely discussed.
2.
However, patients with diabetes often experience elevated fasting blood glucose levels, and their blood glucose levels may remain high throughout the night.
In such cases, physicians may recommend measuring pre-bedtime blood glucose levels and may also consider administering intermediate-acting insulin before bedtime to prevent excessively high blood glucose levels during the night, or they may increase the dose of intermediate-acting insulin before dinner.
This requires clinical consideration.

More Info

Normal bedtime blood sugar levels for non-diabetics typically range from 90 to 130 mg/dL (milligrams per deciliter). However, it is important to note that individual variations can occur based on factors such as diet, physical activity, and overall health. Understanding these levels is crucial for maintaining optimal health and preventing the onset of diabetes.

Blood sugar levels fluctuate throughout the day, influenced by food intake, physical activity, and hormonal changes. For non-diabetics, the body effectively regulates blood sugar levels through insulin and glucagon, hormones produced by the pancreas. Insulin helps lower blood sugar levels after meals, while glucagon raises blood sugar levels when they drop too low. This balance is essential for maintaining energy levels and overall metabolic health.

When considering bedtime blood sugar levels, it is essential to recognize that levels can be affected by what and when a person eats. For instance, consuming a high-carbohydrate meal close to bedtime can lead to elevated blood sugar levels, while a balanced meal with protein, healthy fats, and fiber may help maintain stable levels. Additionally, engaging in physical activity during the day can improve insulin sensitivity, leading to better blood sugar control.

For individuals without diabetes, a bedtime blood sugar level within the normal range is a good indicator of effective glucose metabolism. However, if levels are consistently above 130 mg/dL, it may signal insulin resistance or prediabetes, which can increase the risk of developing type 2 diabetes. In such cases, lifestyle modifications, including dietary changes and increased physical activity, are recommended to improve blood sugar control.

It is also worth noting that the American Diabetes Association (ADA) provides guidelines for blood sugar levels, which can serve as a reference for individuals monitoring their health. For non-diabetics, fasting blood sugar levels should be below 100 mg/dL, while postprandial (after eating) levels should be less than 140 mg/dL two hours after a meal. Maintaining blood sugar levels within these ranges is crucial for long-term health.

In conclusion, for non-diabetics, normal bedtime blood sugar levels should ideally fall between 90 and 130 mg/dL. Monitoring these levels can help individuals maintain their health and prevent potential complications associated with abnormal blood sugar levels. If there are concerns about blood sugar levels, it is advisable to consult a healthcare professional for personalized guidance and recommendations. Regular check-ups and blood tests can provide valuable insights into one's metabolic health and help identify any necessary lifestyle changes to promote optimal well-being.
