Why Your Fasting Blood Sugar Is High and 5 Ways to Fix It

Waking up to a high fasting blood sugar level can be frustrating, especially if you're actively managing your blood sugar. While it might seem counterintuitive—you haven’t eaten all night, after all—there are several reasons why this happens. This article will explain why your fasting blood sugar might be high and provide 5 actionable steps you can take to improve it.

Fasting blood sugar refers to your blood glucose level after not eating or drinking anything (except water) for at least eight hours, typically overnight. A normal fasting blood sugar level is generally considered to be between 70 and 99 mg/dL. Levels above 100 mg/dL may indicate prediabetes, and levels of 126 mg/dL or higher on two separate tests can suggest diabetes.

Why is My Fasting Blood Sugar High?

Several factors can contribute to elevated fasting glucose levels, and it's important to understand them to address the issue effectively.

• Dawn Phenomenon: This is a natural rise in blood sugar that occurs in the early morning hours. Your body releases hormones like cortisol and growth hormone, which signal the liver to release glucose into the bloodstream to provide energy as you prepare to wake up. This is a normal process, but if you have diabetes or prediabetes, your body may not be able to manage the extra glucose effectively.

• 

  Somogyi Effect (Rebound Hyperglycemia): This occurs when your blood sugar drops too low during the night (often due to medication, particularly insulin) and your body responds by releasing hormones to raise it. This can result in high fasting blood sugar. This is somewhat controversial and not all experts agree on how common it is.

  

• Medication: Certain medications, such as steroids and some diuretics, can raise blood sugar levels.

• Stress: Stress hormones, like cortisol, can elevate blood sugar.

• Diet: What you eat the night before can impact your fasting blood sugar. High-carbohydrate or sugary meals can lead to higher glucose levels in the morning.

• Liver Glycogen Release: Your liver stores glucose in the form of glycogen. During the night, when you're not eating, your liver releases glucose to keep your blood sugar stable. If this release is excessive, it can result in high fasting blood glucose.

• Insulin Resistance: If your body is resistant to insulin, glucose can't enter your cells as easily, leading to elevated blood sugar levels.

5 Ways to Fix High Fasting Blood Sugar

Here are five practical strategies you can implement to manage and lower your high fasting blood sugar:

1. Review Your Bedtime Routine and Evening Meal: Analyze what you're eating for dinner and your bedtime habits. Avoid large, carbohydrate-rich meals close to bedtime. Opt for a balanced meal with protein, healthy fats, and complex carbohydrates. Experiment with adjusting the timing of your dinner and see how it affects your morning readings. Consider a small protein-rich snack before bed, if appropriate for you, to help stabilize blood sugar overnight.

2. Monitor Blood Sugar Levels Throughout the Night: Consider using a continuous glucose monitor (CGM) or checking your blood sugar at various times during the night (e.g., 2 AM, 4 AM) to identify if you're experiencing the Somogyi effect (low blood sugar followed by a rebound high). This can help your doctor adjust your medication appropriately. Even without a CGM, occasional nighttime checks can provide valuable insights.

3. Adjust Your Medication (With Doctor's Guidance): If you are taking diabetes medication, work closely with your doctor to adjust the dosage or timing, especially if you suspect the Somogyi effect. Do not make any medication changes without consulting your healthcare provider. They may also review other medications you're taking to see if they're contributing to the problem.

4. Manage Stress Levels: Incorporate stress-reducing activities into your daily routine. This could include meditation, yoga, deep breathing exercises, spending time in nature, or engaging in hobbies you enjoy. Chronic stress can significantly impact blood sugar control. Consider speaking with a therapist if you struggle with stress management.

   

5. Incorporate Regular Physical Activity: Regular exercise can improve insulin sensitivity and help lower blood sugar levels. Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Consider incorporating resistance training as well, as it can improve glucose metabolism. Be sure to consult your doctor before starting a new exercise program.

When to See a Doctor

It’s important to consult with your doctor if you consistently experience high fasting blood sugar, especially if you have other symptoms of diabetes, such as frequent urination, excessive thirst, unexplained weight loss, or blurred vision. They can help determine the underlying cause and develop a personalized treatment plan. Regular monitoring of your fasting blood sugar is crucial for effectively managing your health.
