High Blood Sugar Symptoms: 9 Signs You Shouldn't Ignore
High blood sugar, or hyperglycemia, occurs when your body has too much glucose in the blood. This can happen if your body doesn't make enough insulin (in type 1 diabetes), or if your body can't use insulin properly (in type 2 diabetes). It can also be caused by other factors like stress, illness, or certain medications. Recognizing the signs of high blood sugar is crucial for preventing serious health complications. This article will delve into nine common symptoms of high blood sugar that you shouldn't ignore, offering insights into their causes and what you should do if you experience them.
1. Frequent Urination (Polyuria)
One of the earliest and most noticeable symptoms of hyperglycemia is frequent urination, also known as polyuria. When your blood sugar levels are high, your kidneys try to flush out the excess glucose through urine. This results in needing to urinate more often, especially at night. The kidneys work overtime to filter and reabsorb glucose, and when the blood sugar is too high, they can't keep up, leading to excess glucose being excreted in urine. This contributes to the other symptoms discussed below, notably increased thirst and dehydration.
2. Increased Thirst (Polydipsia)
As your body loses fluids through frequent urination, you'll likely experience increased thirst, or polydipsia. The body tries to compensate for the fluid loss by signaling the need for more fluids. Even after drinking water, you might still feel thirsty because your body is continuously trying to dilute the high glucose concentration in your blood. This is a cyclical process: high blood sugar leads to frequent urination, which leads to increased thirst, which can, in turn, further strain the body if the underlying cause of high blood sugar is not addressed.
3. Unexplained Weight Loss

Even if you’re eating more than usual, unexplained weight loss can be a symptom of high blood sugar, especially in type 1 diabetes. When your body can’t use glucose for energy (due to a lack of insulin or insulin resistance), it starts breaking down muscle and fat for fuel. This can lead to significant weight loss, even without changes in your diet or exercise habits. Muscle breakdown can occur relatively quickly, compounding the problem and leaving you feeling weak and fatigued, as discussed later. It’s essential to differentiate this from intentional weight loss due to diet and exercise, especially when accompanied by the other symptoms mentioned here.
4. Fatigue

High blood sugar levels can interfere with your body's ability to efficiently use glucose for energy, leading to persistent fatigue. Even if you’re getting enough sleep, you might feel tired and sluggish. Glucose is the primary source of energy for cells. However, when it cannot enter the cells efficiently, energy production suffers, leading to fatigue. This fatigue is often coupled with irritability and difficulty concentrating, making it even more challenging to manage daily activities.
5. Blurred Vision
Elevated blood sugar levels can cause fluid to be pulled from the lenses of your eyes, leading to blurred vision. This is often a temporary issue and may improve as blood sugar levels are stabilized. However, prolonged periods of high blood sugar can damage the small blood vessels in the eyes (retinopathy), potentially leading to long-term vision problems. It's important to get regular eye exams, especially if you have diabetes or suspect you may have high blood sugar. Fluctuations in blood glucose levels are often directly linked to transient periods of blurred vision.
6. Slow-Healing Sores or Cuts
Slow-healing sores or cuts are a common sign of high blood sugar. High blood sugar can impair blood circulation and nerve function, which can hinder the body's natural healing process. This means even minor cuts or bruises may take longer to heal, and they may be more prone to infection. The compromised immune function further exacerbates the situation. Therefore, any unusual delays in wound healing should be promptly evaluated, especially when accompanied by other symptoms outlined here.
7. Frequent Infections
High blood sugar can weaken your immune system, making you more susceptible to frequent infections. Elevated glucose levels provide a favorable environment for bacteria and yeast to thrive, increasing the risk of infections such as urinary tract infections (UTIs), skin infections, and yeast infections. Moreover, the body’s natural defense mechanisms are less effective when blood sugar levels are consistently high. Recurrent or persistent infections that don’t respond well to initial treatment should raise suspicion.
8. Numbness or Tingling (Neuropathy)
Long-term high blood sugar can damage nerves, leading to a condition called diabetic neuropathy. Symptoms of neuropathy include numbness, tingling, or burning sensations in your hands and feet. This damage occurs because high glucose levels interfere with the nerves’ ability to transmit signals effectively. Over time, this nerve damage can become irreversible. Therefore, proactive management of blood sugar levels is paramount to prevent the onset and progression of diabetic neuropathy.

9. Dry, Itchy Skin
High blood sugar can lead to dry, itchy skin. This can be due to the body pulling moisture from the skin to help flush out excess glucose. Also, poor circulation caused by high blood sugar can contribute to skin problems. Diabetic dermopathy, a specific skin condition characterized by small, reddish-brown, scaly patches often on the shins, is also common. Adequate hydration, moisturizing, and addressing the underlying blood sugar imbalance can alleviate the symptoms.
What to Do If You Experience These Symptoms
If you experience any of these symptoms, especially in combination, it's important to consult a healthcare professional. A doctor can perform tests to check your blood sugar levels and determine if you have diabetes or prediabetes.
Here are some steps you might need to take:
- Get a Blood Sugar Test: This will provide immediate insight into your glucose levels.
- Consult with a Doctor: Discuss your symptoms and get a thorough evaluation.
- Dietary Changes: Reducing sugar and refined carbohydrate intake.
- Regular Exercise: Increasing physical activity to improve insulin sensitivity.
- Medication: If diagnosed with diabetes, following your doctor's prescribed medication plan.
Complications of Untreated High Blood Sugar
Ignoring the symptoms of high blood sugar can lead to serious and potentially life-threatening complications, including:
- Diabetic Ketoacidosis (DKA): A dangerous condition caused by a severe lack of insulin.
- Hyperosmolar Hyperglycemic State (HHS): A condition where blood sugar levels are extremely high, leading to severe dehydration.
- Cardiovascular Disease: Increased risk of heart attack and stroke.
- Kidney Disease: Damage to the kidneys, potentially leading to kidney failure.
- Nerve Damage (Neuropathy): As discussed earlier, causing pain, numbness, and tingling.
- Eye Damage (Retinopathy): Potentially leading to blindness.
- Foot Problems: Increased risk of infections, ulcers, and amputation.
Monitoring Blood Sugar Levels: A Summary
Regularly monitoring blood sugar levels is an essential aspect of managing diabetes or prediabetes. The frequency of monitoring may vary based on individual treatment plans and doctor's recommendations. Common methods of blood sugar monitoring include:
- Home Blood Glucose Monitoring (HBGM): Using a blood glucose meter to check blood sugar levels at various times throughout the day.
- Continuous Glucose Monitoring (CGM): Utilizing a small sensor inserted under the skin to continuously track glucose levels, providing real-time data and alerts.
- A1C Test: A blood test that provides an average of blood sugar levels over the past 2-3 months.
| Monitoring Method | Description | Frequency |
|---|---|---|
| Home Blood Glucose Monitoring (HBGM) | Checking blood sugar with a glucose meter. | Varies based on individual needs; often multiple times per day for those on insulin. |
| Continuous Glucose Monitoring (CGM) | Continuous tracking via a sensor under the skin. | Provides real-time data and alerts; typically worn for several days at a time. |
| A1C Test | Provides an average blood sugar level over the past 2-3 months. | Typically performed every 3-6 months, or as recommended by your doctor. |
Conclusion
Recognizing the early signs of high blood sugar and taking prompt action is essential for preventing serious complications and maintaining overall health. If you experience any of the symptoms discussed in this article, consult with a healthcare professional for proper diagnosis and management. Proactive management of blood sugar levels through diet, exercise, and medication (if needed) can significantly improve your quality of life and reduce the risk of long-term health problems.
