High blood sugar, also known as hyperglycemia, occurs when there is too much glucose in the bloodstream. This condition can be dangerous if left untreated, as it can lead to long-term complications such as heart disease, kidney damage, and nerve damage. Recognizing the symptoms of high blood sugar is crucial in order to take action and prevent further complications. In this article, we will discuss the common signs of hyperglycemia and how to recognize them.

High Blood Sugar Symptoms

Hyperglycemia can cause a variety of symptoms, which can vary in severity depending on the individual and the level of blood sugar. Some common symptoms of high blood sugar include:

  1. Increased thirst: One of the first signs of hyperglycemia is feeling extremely thirsty, as the body tries to flush out the excess glucose through urination.
  2. Frequent urination: Excess glucose in the bloodstream can cause the kidneys to work overtime to filter it out, leading to more frequent trips to the bathroom.
  3. Fatigue: High blood sugar can make you feel tired and lethargic, as the cells are unable to properly use glucose for energy.

More Symptoms to Look out For

In addition to the common symptoms mentioned above, hyperglycemia can also cause the following signs:

  1. Blurred vision: High blood sugar can affect the shape of the lens in your eye, leading to blurred vision.
  2. Slow healing wounds: Elevated blood sugar levels can impair the body’s ability to heal wounds, making cuts and bruises take longer to heal.
  3. Dry mouth and skin: Dehydration from frequent urination can cause dry mouth and skin, as well as itching and skin infections.

When to Seek Medical Help

If you are experiencing any of these symptoms of high blood sugar, it is important to monitor your blood sugar levels and consult with a healthcare professional. In severe cases, hyperglycemia can lead to a condition called diabetic ketoacidosis, which is a life-threatening emergency. Symptoms of diabetic ketoacidosis include nausea, vomiting, and confusion, and require immediate medical attention.


Recognizing the symptoms of high blood sugar is crucial in managing diabetes and preventing long-term complications. By being aware of the signs of hyperglycemia, individuals can take proactive steps to monitor their blood sugar levels and make necessary lifestyle changes to keep their condition under control.
