Hyperglycemia, or high blood sugar, is a condition that occurs when your body doesn’t produce enough insulin or doesn’t effectively use the insulin it produces. It is commonly associated with diabetes, both type 1 and type 2.

Hyperglycemia can be a serious condition if left untreated, and it’s important to be aware of the warning signs so that you can take prompt action. In this article, we will discuss the various signs that indicate high blood sugar levels.

1. Frequent urination

Frequent urination, also known as polyuria, is one of the most common warning signs of hyperglycemia. When your blood sugar levels are high, your kidneys try to remove the excess sugar through urine.

This leads to an increased need to urinate, especially during the night.

2. Excessive thirst

Excessive thirst, known as polydipsia, often accompanies frequent urination. As your body loses more fluids through urine, you may feel an intense thirst that cannot be quenched, no matter how much you drink.

This is a result of the body’s attempt to replenish the lost fluids.

3. Increased hunger

Hyperglycemia can also lead to increased hunger or excessive appetite, known as polyphagia.

Despite eating regularly, individuals with high blood sugar levels may still feel hungry due to the body’s inability to effectively use the glucose for energy.

4. Fatigue

Feeling constantly tired or fatigued can be a sign of hyperglycemia. When your body doesn’t have enough insulin or can’t use it properly, glucose stays in the bloodstream instead of being transported to the cells for energy.

As a result, you may feel drained, lacking energy, and overall fatigued.

5. Blurred vision

High blood sugar levels can lead to temporary changes in the lens within your eyes, resulting in blurred vision. This occurs due to osmotic changes caused by excess glucose.

If your vision suddenly becomes blurry, it’s essential to check your blood sugar levels and take appropriate actions.

6. Slow healing of wounds

One of the long-term effects of hyperglycemia is impaired wound healing. High blood sugar levels can damage blood vessels and affect the circulation, reducing the delivery of oxygen and nutrients to the injured tissues.

If you notice that your wounds are taking longer to heal than usual, it could be a sign of hyperglycemia.

7. Recurrent infections

Hyperglycemia weakens the immune system, making it harder for your body to fight off infections. This can lead to more frequent and persistent infections, such as urinary tract infections, yeast infections, and skin infections.

If you find yourself getting sick frequently, it’s important to consider hyperglycemia as a possible cause.

8. Unexplained weight loss

Sudden and unexplained weight loss can be an alarming sign of hyperglycemia, especially in individuals with type 1 diabetes.

When your body doesn’t have enough insulin or can’t use it effectively, it starts to break down fat and muscle for energy, resulting in weight loss. If you are losing weight without trying, it’s crucial to consult a healthcare professional.

9. Dry mouth

A consistently dry mouth, also known as xerostomia, can be a warning sign of hyperglycemia. High blood sugar levels can cause changes in the salivary glands, leading to reduced saliva production.

This can result in a dry, sticky feeling in the mouth, which can make swallowing and speaking uncomfortable.

10. Mood changes

Hyperglycemia can affect your mood and overall mental well-being. Fluctuating blood sugar levels can lead to irritability, increased stress, difficulty concentrating, and even depression.

If you notice significant changes in your mood or emotions, it’s important to monitor your blood sugar levels and seek appropriate medical help.
