What Are the Symptoms of High Blood Sugar? 7 Signs to Watch For
High blood sugar, also known as hyperglycemia, occurs when your body has too much glucose (sugar) in the blood. This can happen for a variety of reasons, but it's most commonly associated with diabetes. Recognizing the symptoms of high blood sugar is crucial for managing your health and preventing serious complications. In this article, we'll explore 7 key signs you need to watch for and what to do if you experience them.
Understanding High Blood Sugar
Before we delve into the symptoms, it's important to understand what causes high blood sugar. In individuals with diabetes, the body either doesn't produce enough insulin (Type 1 diabetes) or doesn't use insulin effectively (Type 2 diabetes). Insulin is a hormone that helps glucose from food get into your cells to be used for energy. When insulin is lacking or ineffective, glucose builds up in the bloodstream, leading to hyperglycemia. Other factors that can contribute to high blood sugar include:

7 Key Symptoms of High Blood Sugar
Here are seven common symptoms of hyperglycemia that you should be aware of:
- Frequent Urination (Polyuria): One of the earliest and most noticeable signs of high blood sugar is increased urination, especially at night. Your kidneys work overtime to filter out the excess sugar, leading to increased urine production.
- Increased Thirst (Polydipsia): Because your body is losing fluids through frequent urination, you'll likely experience intense thirst. This is your body's way of trying to replenish the lost fluids and dilute the high blood sugar concentration.
- Unexplained Weight Loss: When your body can't use glucose for energy, it starts breaking down muscle and fat for fuel. This can result in unintended weight loss, even if you're eating normally.
- Blurry Vision: High blood sugar can affect the lenses in your eyes, causing them to swell and leading to blurry vision. This is usually temporary and will improve when your blood sugar levels are better managed.
- Fatigue: Persistent fatigue and weakness are common symptoms of hyperglycemia. When your cells aren't getting enough glucose, you feel tired and sluggish, even after getting enough rest.
- Slow-Healing Sores or Cuts: High blood sugar can impair your body's ability to heal. Even minor cuts and sores may take longer to heal than usual, increasing the risk of infection.
- Dry, Itchy Skin: Dehydration due to frequent urination can lead to dry, itchy skin. Additionally, high blood sugar can damage blood vessels and nerves, further contributing to skin problems.
Additional Symptoms and Complications
Besides the core symptoms listed above, other signs of high blood sugar include:
- Headaches
- Nausea
- Concentration difficulties
- Increased susceptibility to infections
Prolonged, uncontrolled hyperglycemia can lead to serious health complications, including:
- Diabetic ketoacidosis (DKA), a life-threatening condition more common in Type 1 diabetes.
- Hyperosmolar hyperglycemic state (HHS), a serious condition more common in Type 2 diabetes.
- Long-term damage to nerves, blood vessels, and organs.
How to Monitor Your Blood Sugar
If you suspect you have high blood sugar, the first step is to monitor your blood glucose levels. For individuals with diabetes, regular blood sugar monitoring is essential for managing their condition. This can be done with a blood glucose meter, which requires a small blood sample taken from your fingertip. Continuous glucose monitors (CGMs) are also available, providing real-time blood sugar readings without the need for frequent finger pricks.

| Monitoring Method | Description | Frequency |
|---|---|---|
| Blood Glucose Meter | Requires a blood sample from a fingertip to measure blood sugar levels. | As recommended by your doctor, typically before meals and at bedtime. |
| Continuous Glucose Monitor (CGM) | Uses a sensor inserted under the skin to continuously track blood sugar levels. | Provides real-time readings and trends throughout the day and night. |
What to Do if You Have High Blood Sugar
If you're experiencing symptoms of high blood sugar, it's important to take action. Here are some steps you can take:

- Check Your Blood Sugar: Use your blood glucose meter or CGM to measure your blood sugar levels. This will help you determine how high your blood sugar is and whether you need to take further steps.
- Drink Plenty of Water: Stay hydrated to help your kidneys flush out the excess sugar.
- Adjust Your Insulin Dosage (If Applicable): If you take insulin, consult your doctor or diabetes educator about adjusting your dosage to bring your blood sugar back into the target range. Never make significant changes to your insulin dosage without professional guidance.
- Exercise (If Appropriate): Light exercise can help lower blood sugar levels, but avoid strenuous activity if your blood sugar is very high or if you have ketones in your urine, as this can make the situation worse.
- Follow Your Diabetes Management Plan: Stick to your prescribed diet, medication regimen, and other recommendations from your healthcare team.
- Seek Medical Attention: If your blood sugar is very high (e.g., above 300 mg/dL) or you experience symptoms of DKA or HHS, seek immediate medical attention.
Preventing High Blood Sugar
Prevention is key to managing high blood sugar and avoiding complications. Here are some tips to help you keep your blood sugar levels in check:
- Follow a Healthy Diet: Choose a balanced diet that's low in sugar and processed foods and high in fiber, fruits, and vegetables.
- Exercise Regularly: Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
- Maintain a Healthy Weight: Losing even a small amount of weight can improve your blood sugar control.
- Take Your Medications as Prescribed: If you have diabetes, follow your doctor's instructions for taking your medications.
- Monitor Your Blood Sugar Regularly: Regular blood sugar monitoring is essential for managing your condition and preventing high blood sugar episodes.
- Manage Stress: Stress can raise blood sugar levels, so find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
- Get Enough Sleep: Lack of sleep can affect your blood sugar control, so aim for 7-8 hours of sleep per night.
