Signs of High Blood Sugar That Appear Right After Waking Up

High blood sugar, or hyperglycemia, is a common concern for many individuals, especially those with diabetes. Monitoring blood sugar levels is crucial for maintaining overall health. One of the key times to check for signs of high blood sugar is right after waking up. Here are some common indicators that your blood sugar levels might be elevated in the morning:

1. Excessive Thirst

One of the earliest signs of high blood sugar is excessive thirst. If you wake up feeling extremely thirsty, it might be an indication that your body is trying to flush out excess glucose through urination, leading to dehydration.

2. Frequent Urination

Closely related to excessive thirst is frequent urination. High blood sugar levels cause your kidneys to work overtime to filter and absorb the excess sugar. If they can’t keep up, the excess sugar is excreted into your urine, drawing fluids from your tissues, which leads to frequent urination.

3. Fatigue

Despite having had a full night’s sleep, waking up feeling unusually tired can be a sign of high blood sugar. When your body is unable to properly use glucose for energy, you can feel fatigued and sluggish, even after resting.

4. Blurred Vision

High blood sugar can cause the lenses of your eyes to swell, leading to temporary blurred vision. If you wake up with your vision being less sharp than usual, it might be an indication that your blood sugar levels are elevated.

5. Dry Mouth and Skin

High blood sugar levels can cause dehydration, leading to symptoms such as dry mouth and skin. If you notice these signs right after waking up, it could be a sign that your blood sugar levels were high overnight.

6. Nausea or Stomach Pain

Elevated blood sugar levels can lead to gastrointestinal issues, including nausea and stomach pain. If you frequently wake up feeling nauseous or with a stomach ache, it might be worth checking your blood sugar levels.

7. Headaches

Waking up with a headache can be another sign of high blood sugar. Dehydration and the body’s struggle to manage glucose levels can contribute to headaches in the morning.

Managing Morning Hyperglycemia

If you frequently experience these symptoms, it’s important to manage your blood sugar levels to avoid long-term health complications. Here are some tips to help regulate your morning blood sugar:

  • Monitor Your Blood Sugar: Regularly check your blood sugar levels, especially before bed and upon waking, to understand your patterns.
  • Adjust Your Diet: Avoid high-carbohydrate snacks before bedtime. Opt for a balanced meal with fiber, protein, and healthy fats.
  • Stay Hydrated: Drink plenty of water throughout the day to stay hydrated and help your kidneys flush out excess sugar.
  • Exercise Regularly: Physical activity helps your body use insulin more efficiently and can help lower blood sugar levels.
  • Medications: If you are on diabetes medication, ensure you are taking it as prescribed. Consult with your healthcare provider if you notice persistent high blood sugar levels.


Recognizing the signs of high blood sugar right after waking up can help you take proactive steps to manage your health. If you frequently experience these symptoms, consult with your healthcare provider to develop a plan to maintain optimal blood sugar levels. By making lifestyle changes and monitoring your levels, you can better manage your blood sugar and improve your overall well-being.
