10 Signs of High Blood Sugar You MUST Know!
High blood sugar, or hyperglycemia, is a common condition that affects millions of people worldwide, particularly those with diabetes. Recognizing the early signs of high blood sugar is crucial for managing your health and preventing serious complications. This article will detail ten key signs you should be aware of, providing practical advice on what to do if you experience them. Understanding these symptoms can help you take timely action and maintain a healthy lifestyle.
Why is it important to recognize high blood sugar? Unmanaged hyperglycemia can lead to a range of severe health issues, including damage to blood vessels, nerves, and vital organs. Early detection and intervention can make a significant difference in long-term health outcomes. Ignoring these symptoms could lead to the development of type 2 diabetes, if not already present, and worsen the condition for those with type 1 or type 2 diabetes. Recognizing high blood sugar early empowers you to take proactive steps toward health management.
1. Increased Thirst (Polydipsia)
One of the hallmark signs of high blood sugar is excessive thirst. When there's too much glucose in your blood, your kidneys work overtime to filter it out. This process can pull fluids from your body, leading to dehydration and the feeling of constant thirst. Polydipsia is the medical term for this condition and it's more than just feeling a bit thirsty after exercise.
- How to identify: If you find yourself drinking significantly more water than usual and you still feel thirsty shortly after, it's a signal to pay attention. This persistent thirst often doesn’t get relieved by just drinking water.
- Example: You might be waking up multiple times in the night just to drink, even if you haven't been physically active recently.
2. Frequent Urination (Polyuria)
Closely linked to increased thirst is the need to urinate more often. This is known as polyuria, another classic symptom of hyperglycemia. When your body attempts to flush out excess glucose through your kidneys, it results in the need to visit the bathroom more often, both day and night.
- How to identify: Notice if you're making significantly more trips to the bathroom than is typical for you. This may be as often as hourly and could cause you to need to wake up in the night to urinate several times.
- Practical Advice: Keep a log of how many times you use the bathroom in a day, this can be a key indicator to share with a medical provider. If you notice a drastic increase without any other change in habits, it may be a sign of high blood sugar.
3. Unexplained Fatigue
Feeling unusually tired despite getting enough sleep is a significant indicator of high blood sugar. This fatigue isn’t the kind you feel after an intense workout, but a constant weariness and lethargy. High blood sugar interferes with your body’s ability to utilize glucose for energy, making you feel drained.
- How to identify: This isn’t just feeling tired, but an overwhelming and persistent fatigue that impacts your daily activities. You might feel like you're dragging through the day, even after resting.
- Real-World Example: Imagine feeling the urge to nap midday consistently despite getting a full night's sleep.
4. Blurred Vision
High blood sugar can affect the lenses of your eyes, causing changes in vision such as blurred vision. The excess glucose in your blood can cause the lens to swell, leading to temporary difficulty focusing. This symptom isn’t always present, but is very characteristic of elevated blood glucose levels.
- How to identify: If your vision seems fuzzy or if you're noticing difficulty reading or seeing clearly, this can be a concerning sign.
- Actionable Advice: It's crucial to get an eye exam to rule out other vision-related issues as soon as possible. You also need to check blood sugar regularly to see if blood sugar is the underlying cause.
5. Increased Hunger (Polyphagia)
Ironically, despite having high blood sugar levels, the cells in your body may not be getting enough glucose, which leads to persistent hunger (known as polyphagia). This occurs when the body is unable to properly utilize the insulin needed to get glucose into the cells for energy.
- How to identify: You might find yourself feeling extremely hungry soon after eating, and this hunger may not go away even after meals.
- Practical Consideration: This condition often leads to a cycle of overeating and increased blood glucose, making it more difficult to control the condition.
6. Slow-Healing Wounds
If you notice that cuts, bruises, or sores take an unusually long time to heal, it might be related to high blood sugar. Elevated glucose levels can impair blood circulation and damage nerve tissues which leads to slow-healing wounds.
- How to Identify: Keep an eye out for small cuts and scrapes on your body. Note if these take longer to heal.
- Additional Info: This includes even very small wounds or skin irritations that linger for an unusually long time.
7. Unexplained Weight Loss
Unintended weight loss can also be an indication of high blood sugar, especially for those who are newly developing the condition. This occurs as your body tries to use alternative forms of energy sources (e.g., fat and protein) because glucose is not effectively being delivered to the cells.
- How to identify: If you're noticing a sudden, unexplained weight loss without any changes in your diet or exercise habits, pay attention to this symptom.
- Important Note: Unexplained weight loss needs to be brought to your doctor’s attention. There may be several underlying medical reasons and appropriate diagnostics should be performed.
8. Dry, Itchy Skin
High blood sugar can cause dry and itchy skin. Dehydration caused by increased urination can lead to skin dryness. High levels of sugar in the blood can also damage nerve endings and blood vessels in the skin, causing itching and discomfort.
- How to identify: If you notice that your skin feels unusually dry, or if it is frequently itchy, and moisturizing doesn't bring relief, this may be a sign of hyperglycemia.
- Consideration: These are not isolated occurrences of dry skin; it's a persistent condition that requires monitoring.
9. Frequent Infections
People with high blood sugar are more prone to developing infections. This includes urinary tract infections, yeast infections, skin infections, and more. This is because high blood sugar can weaken your immune system and make it easier for germs and pathogens to thrive.
- How to identify: If you’re experiencing infections frequently or are finding that infections are lingering and difficult to treat, you should monitor blood glucose levels.
- Note: An overabundance of yeast can often be a sign of hyperglycemia in both males and females.
10. Numbness or Tingling (Neuropathy)
Prolonged periods of high blood sugar can lead to neuropathy, or nerve damage. This may manifest as numbness, tingling, or pain in your hands, feet, or legs. This occurs when consistently elevated glucose levels damage small blood vessels that supply the nerves.
- How to identify: Pay attention to persistent tingling sensations, pain, or numbness that feels like pins and needles.
- Critical Action: Nerve damage is a serious complication of high blood sugar; it needs immediate medical attention to prevent long-term complications.
Actionable Steps to Take
If you're experiencing one or more of these signs, it's essential to take prompt action:
- Monitor Your Blood Sugar: Use a blood glucose meter to check your levels, particularly before and after meals.
- Consult Your Doctor: Schedule an appointment with your healthcare provider to discuss your symptoms and determine the appropriate course of action.
- Lifestyle Adjustments: Implement lifestyle changes such as incorporating regular physical activity, following a balanced diet low in refined sugars and carbohydrates, and losing weight if needed.
- Medication: If you are diagnosed with diabetes, follow your prescribed medications diligently.
- Regular Follow-Up: Adhere to regular check-ups with your doctor and other healthcare providers to ensure effective management of your condition.
Conclusion
Recognizing the early warning signs of high blood sugar can play a crucial role in preventing long-term health complications. Be aware of changes in your body and take immediate steps to check your blood sugar if you suspect your levels may be high. The key to managing high blood sugar effectively lies in a proactive and well-informed approach. By staying vigilant and seeking timely medical advice, you can effectively control your blood sugar and ensure a healthier future.

Today we’re going to talk about cholesterol, and I want to cover the seven foods that lower bad cholesterol. HDL is considered good cholesterol, and LDL is considered bad cholesterol. But, there are two types of LDL. The real villain when it comes to cholesterol and heart problems is a very specific type of LDL. To measure this type of LDL, you have to ask for a test called an advanced lipid profile test. With this test, they’re looking at the number and size of the particles that carry cholesterol. The two types, or particle sizes, of LDL, are: 1. The large buoyant (pattern A) 2. The small dense (pattern B) The small dense LDL particles are the ones you have to be concerned about because they can penetrate the arteries, even though the large buoyant type carries more cholesterol. Small dense LDL is a strong predictor of cardiovascular disease. This topic can be confusing because some people have low LDL cholesterol but a high number of small dense particles. Others have high LDL with a high number of large buoyant particles. This is why it’s so important to get an advanced lipid profile test, so you have the whole picture of what’s going on. Top foods that lower bad cholesterol (small dense LDL): 1. Extra virgin olive oil 2. Avocados 3. Fish oils or cod liver oil 4.
