Heart: Uncommon Signs Of High Blood Sugar Levels In Summer


With the mercury rising, it’s crucial to pay close attention to your body, especially if you have diabetes or are at risk of developing it. While many are familiar with the typical symptoms of high blood sugar like increased thirst, frequent urination, and fatigue, the summer heat can bring about some less common signs that your blood sugar levels may be out of control. Here are some uncommon indicators to watch out for:

1. Fruity Breath Odor

While fruity breath might seem innocuous, it can be a sign of diabetic ketoacidosis (DKA), a serious complication of diabetes. During summer, when dehydration is more common, DKA risk increases. If you notice a fruity or acetone-like odor on your breath, it’s essential to check your blood sugar levels promptly.

2. Blurry Vision

High blood sugar levels can cause the lens inside your eye to swell, leading to blurry vision. In the summer, when dehydration is more likely due to excessive sweating, this symptom can become more pronounced. If you experience sudden changes in your vision, particularly in hot weather, it’s vital to get your blood sugar levels checked.

    3. Skin Infections or Rashes

    Heat and humidity create the perfect breeding ground for fungal infections like yeast infections and jock itch. High blood sugar levels can exacerbate these conditions, leading to persistent or recurrent infections. If you notice any unusual rashes or persistent itching, especially in areas prone to moisture, it’s crucial to consult your healthcare provider.

    4. Difficulty Concentrating

    Heat can affect your cognitive function, and when combined with high blood sugar levels, it can lead to difficulty concentrating or thinking clearly. If you find yourself struggling to focus or experiencing mental fog more than usual during the summer months, it could be a sign that your blood sugar levels are too high.

    5. Cramping or Muscle Weakness

    Electrolyte imbalances due to dehydration can exacerbate muscle cramps and weakness, which are already common symptoms of high blood sugar levels. If you’re experiencing frequent muscle cramps or weakness, particularly during hot weather or physical activity, it’s essential to monitor your blood sugar levels and stay hydrated.

    6. Increased Hunger Despite the Heat

    While heat typically suppresses appetite, persistent hunger despite high temperatures can be a sign of uncontrolled blood sugar levels. Insulin resistance can prevent glucose from entering your cells, leaving you feeling hungry even when you’ve recently eaten. If you find yourself constantly hungry, especially during summer when appetite tends to decrease, it’s essential to speak with your healthcare provider.

    7. Mood Swings or Irritability

    Fluctuations in blood sugar levels can affect your mood, leading to irritability, anxiety, or even depression. During summer, when factors like heat and dehydration can further impact your mood, it’s essential to monitor any changes in how you’re feeling. If you notice unexplained mood swings or increased irritability, it may be worth checking your blood sugar levels.


    In conclusion, while high blood sugar levels can present with the typical symptoms like increased thirst and fatigue, the summer heat can bring about some less common signs that warrant attention. By staying vigilant and monitoring your body for these uncommon indicators, you can better manage your diabetes and stay healthy during the warmer months. If you experience any of these symptoms, especially if they persist or worsen, don’t hesitate to consult your healthcare provider for proper evaluation and management.
