How to tell if your blood sugar level or hyperglycemia is high

  • Hyperglycemia or hyperglycemia occurs when a person's body does not manufacture or properly use insulin, a hormone. Insulin helps the body convert the glucose contained in food into energy.
  • Hyperglycemia does not affect only diabetics. This can also come from infections, stress, inactivity and other problems.
  • Signs of hyperglycemia include constant fatigue or thirst, chronic headaches, and blurred vision.

When you hear the term "high blood sugar," you probably think of people with diabetes and needing insulin to keep their bodies in balance. But hyperglycemia or hyperglycemia can also affect people without diabetes. And, if left untreated, it can lead to nerve damage, kidneys, eyes, or heart disease.

High blood sugar occurs when a person's body does not produce or does not use enough insulin, a hormone that helps turn the food you consume into usable energy in your body. As a result, a person may feel constantly tired, constantly thirsty, have blurred vision or feel a host of other symptoms. According to the Mayo Clinic, these symptoms do not appear immediately and may take days or weeks to develop as blood glucose levels increase.

In addition to type 1 or 2 diabetes, having an infection, being inactive, being stressed and eating too much carbohydrate can lead to hyperglycemia. People with cystic fibrosis and those who take beta-blockers may also have an increased risk of hyperglycemia.

To be diagnosed with high blood glucose, you will need a blood test to determine if your blood glucose is too high. Consult a doctor for a test as soon as possible if you notice any of these six signs.
