What Is Hyperglycemia? How to Prevent, Detect, and Treat High Blood Sugar

We understand that managing type 2 diabetes can be challenging, and one of the complications you might face is hyperglycemia. Hyperglycemia occurs when your blood sugar levels rise above the normal range, and it can have serious consequences if left untreated. In this article, we will provide you with detailed information about hyperglycemia, its causes, symptoms, and treatments, to help you better manage your diabetes.

What is Hyperglycemia?

Hyperglycemia is a medical condition where your blood sugar levels are higher than normal. Blood sugar, also known as blood glucose, is the primary source of energy for your body’s cells. Insulin, a hormone produced by the pancreas, helps regulate blood sugar levels by allowing glucose to enter your cells.

When you have diabetes, your body either doesn’t produce enough insulin, or it cannot use insulin properly. As a result, glucose builds up in your bloodstream, causing hyperglycemia.

Causes of Hyperglycemia

Several factors can cause hyperglycemia, including:

  • Eating too much or consuming high-carbohydrate foods
  • Skipping or delaying meals
  • Not taking enough insulin or diabetes medication
  • Physical or emotional stress
  • Infection or illness
  • Hormonal changes, such as those during menstruation or menopause

Symptoms of Hyperglycemia

The symptoms of hyperglycemia can vary from person to person, but they typically include:

  • Increased thirst
  • Frequent urination
  • Fatigue
  • Blurred vision
  • Headache
  • Dry mouth
  • Nausea and vomiting
  • Shortness of breath
  • Confusion
  • Fruity-smelling breath

If you experience any of these symptoms, you should check your blood sugar levels immediately and contact your healthcare provider.

Complications of Hyperglycemia

If left untreated, hyperglycemia can cause several complications, including:

  • Diabetic ketoacidosis (DKA), a life-threatening condition that occurs when your body produces high levels of blood acids called ketones
  • Hyperosmolar hyperglycemic state (HHS), a condition that can cause seizures, coma, and even death
  • Nerve damage
  • Kidney damage
  • Eye damage
  • Cardiovascular disease

Treatment of Hyperglycemia

If you experience hyperglycemia, you should follow your healthcare provider’s recommendations to lower your blood sugar levels. Treatment options may include:

  • Taking insulin or diabetes medication as prescribed
  • Monitoring your blood sugar levels regularly
  • Following a healthy diet and exercise plan
  • Drinking plenty of water and avoiding sugary drinks
  • Avoiding alcohol and caffeine
  • Managing stress levels
  • Getting enough sleep

You may also need to adjust your insulin or diabetes medication dosage, depending on your blood sugar levels.

Frequently Asked Questions:

1. What is the difference between hyperglycemia and diabetes?

Hyperglycemia is a condition where blood sugar levels are too high. Diabetes is a chronic medical condition where the body is unable to produce enough insulin or use it properly, leading to high blood sugar levels.

2. Can hyperglycemia be prevented?

Maintaining a healthy lifestyle, such as eating a balanced diet and getting regular exercise, can help prevent hyperglycemia. If you have diabetes, it is important to monitor your blood sugar levels regularly to prevent hyperglycemia.

3. How is hyperglycemia diagnosed?

Hyperglycemia is diagnosed through a blood test that measures the amount of glucose in the blood.

4. Who is at risk for developing hyperglycemia?

Anyone can develop hyperglycemia, but certain factors can increase your risk. These include having diabetes, being overweight or obese, having a family history of diabetes, and being physically inactive.

5. How often should I check my blood sugar levels if I have hyperglycemia?

The frequency of blood sugar testing will depend on the severity of your condition and the treatment plan recommended by your healthcare provider. Some people with hyperglycemia may need to check their blood sugar levels several times a day, while others may only need to check a few times a week.

6. Can hyperglycemia cause long-term health problems?

Yes, if left untreated, hyperglycemia can lead to a variety of long-term health problems, including diabetes, heart disease, nerve damage, and kidney damage. That’s why it’s important to manage hyperglycemia and work with your healthcare team to prevent complications.

7. Are there any natural remedies or supplements that can help with hyperglycemia?

While some natural remedies and supplements have been suggested to help with hyperglycemia, it’s important to talk to your healthcare provider before trying any new treatments. Some supplements, such as chromium and magnesium, may have a beneficial effect on blood sugar levels, but more research is needed to determine their effectiveness and safety.

8. Can hyperglycemia cause hypoglycemia?

Yes, in some cases, hyperglycemia can cause hypoglycemia (low blood sugar). This can happen if you take too much insulin or other diabetes medications, causing your blood sugar levels to drop too low. It’s important to work with your healthcare team to find the right balance of medication to avoid both hyperglycemia and hypoglycemia.


Hyperglycemia is a common complication of type 2 diabetes that can have serious consequences if left untreated. By understanding its causes, symptoms, and treatments, you can better manage your diabetes and prevent complications. If you experience any symptoms of hyperglycemia, you should check your blood sugar levels and contact your healthcare provider immediately. Remember to follow your treatment plan and monitor your blood sugar levels regularly to maintain healthy blood sugar levels.
