14 Signs showing that your blood sugar is very high

Maintaining stable blood sugar levels is crucial for overall health and well-being. When blood sugar levels become too high, it can indicate an underlying condition such as diabetes or prediabetes. Recognizing the signs of high blood sugar is important for early intervention and effective management of these conditions. In this article, we will discuss 14 common signs that may indicate your blood sugar levels are elevated.

1. Frequent Urination (Polyuria)

Experiencing an increased need to urinate, especially during the night, can be a sign of high blood sugar. When blood sugar levels are elevated, the kidneys try to remove the excess sugar by filtering it into the urine. This leads to increased urination.

2. Excessive Thirst (Polydipsia)

High blood sugar can cause dehydration, leading to an intense and persistent feeling of thirst. If you find yourself constantly reaching for fluids and feeling thirsty even after drinking, it could be a sign of elevated blood sugar levels.

3. Increased Hunger (Polyphagia)

Elevated blood sugar levels can disrupt the body’s insulin response, which can lead to increased hunger. Despite consuming a sufficient amount of food, you may still feel hungry and experience frequent food cravings.

4. Unexplained Weight Loss

Unexpected weight loss can be a sign of high blood sugar, particularly in individuals with undiagnosed or uncontrolled diabetes. When blood sugar levels are elevated, the body may start breaking down muscle and fat for energy, leading to unintentional weight loss.

5. Fatigue and Weakness

High blood sugar levels can prevent glucose from adequately entering the cells to provide energy, resulting in feelings of fatigue and weakness. If you find yourself constantly tired, even after getting enough rest, it may be worth considering blood sugar as a potential factor.

6. Blurred Vision

    Elevated blood sugar levels can cause changes in fluid levels within the eyes, leading to blurred vision. This symptom may improve with proper blood sugar management and treatment.

    7. Slow Wound Healing

    If you notice that cuts, bruises, or other wounds are taking longer to heal than usual, it could be a sign of high blood sugar. Elevated blood sugar levels can affect the body’s ability to repair damaged tissues and fight off infections.

    8. Frequent Infections

    High blood sugar weakens the immune system, making individuals more susceptible to infections. Recurring infections, such as urinary tract infections, yeast infections, or skin infections, could be an indication of elevated blood sugar levels.

    9. Dry Mouth and Skin

    When blood sugar is consistently high, it can lead to dehydration, resulting in dry mouth and skin. You may notice a constant parched feeling in your mouth and skin that feels dry and itchy.

    10. Nerve Damage (Neuropathy)

    Prolonged high blood sugar levels can damage the nerves, resulting in symptoms such as tingling, numbness, or a burning sensation, usually starting in the feet and gradually progressing upward.

    11. Frequent Headaches

    Fluctuations in blood sugar levels can trigger headaches. If you experience frequent, unexplained headaches, it may be worth monitoring your blood sugar levels and consulting with a healthcare professional.

    12. Difficulty Concentrating

    High blood sugar levels can affect cognitive function and make it difficult to concentrate or focus. If you find yourself struggling with mental clarity and experiencing memory problems, it could be a result of elevated blood sugar.

    13. Irritability and Mood Swings

    Blood sugar imbalances can impact mood stability, leading to irritability, mood swings, and feelings of anxiety or depression. Managing blood sugar levels can help stabilize moods and improve emotional well-being.

    14. Persistent Skin Infections

    High blood sugar levels can create a favorable environment for fungal and bacterial growth, leading to persistent skin infections such as fungal nail infections, athlete’s foot, or recurring skin rashes.


    Recognizing the signs of high blood sugar is essential for early detection and management of conditions like diabetes or prediabetes. If you experience multiple symptoms such as frequent urination, excessive thirst, increased hunger, unexplained weight loss, fatigue, blurred vision, slow wound healing, frequent infections, dry mouth and skin, nerve damage, headaches, difficulty concentrating, irritability, mood swings, or persistent skin infections, it is important to consult with a healthcare professional for proper evaluation and diagnosis. With proper medical guidance and lifestyle adjustments, you can effectively manage your blood sugar levels and promote overall health and well-being.
