Prediabetes is a warning sign of potential diabetes, characterized by higher than normal blood glucose levels. Causes include obesity and poor diet. Symptoms may not be apparent, but increased thirst and fatigue may occur. Diagnosis is done through various blood tests. Treatment and prevention involve lifestyle changes like adopting a healthy diet, increasing physical activity, and losing weight if necessary. Regular check-ups are crucial in managing prediabetes and preventing the onset of type 2 diabetes.


Prediabetes is a medical condition characterized by blood glucose levels that are higher than normal but not high enough to be diagnosed as type 2 diabetes. It is considered a warning sign that you are at risk for developing diabetes in the future. Prediabetes is a serious health condition that requires attention and lifestyle changes to prevent the progression to full-blown diabetes. In this article, we will explore the definition, causes, symptoms, and treatment options for prediabetes.

Causes of Prediabetes

Prediabetes occurs when your body does not effectively use insulin or when it doesn't produce enough insulin to regulate blood sugar levels properly. Several factors can contribute to the development of prediabetes, including:

  • Obesity and excess body weight

  • Lack of physical activity

  • Poor diet, especially one high in sugar and unhealthy fats

  • Family history of diabetes

  • High blood pressure or high cholesterol levels

  • Gestational diabetes during pregnancy

Symptoms of Prediabetes

Unlike diabetes, prediabetes often doesn't exhibit any noticeable symptoms. Many people with prediabetes are unaware of their condition until it progresses to diabetes or until they undergo routine blood tests. However, some individuals may experience mild symptoms such as increased thirst, frequent urination, fatigue, and blurred vision. If you have these symptoms or fall into the high-risk category, it is essential to get tested for prediabetes.

Diagnosis of Prediabetes

To diagnose prediabetes, your healthcare provider may perform one of the following tests:

  • Oral glucose tolerance test (OGTT): This test measures blood sugar levels after fasting and again two hours after consuming a glucose-rich drink.

  • Fasting plasma glucose (FPG) test: This test measures blood sugar levels after an overnight fast.

  • Hemoglobin A1c test: This test provides an average of your blood sugar levels over the past few months.

If your test results show that your blood sugar levels are higher than normal but not high enough for a diabetes diagnosis, you will be diagnosed with prediabetes.

Treatment and Prevention

Fortunately, prediabetes can often be reversed or prevented through lifestyle changes. Here are some strategies that can help:

  • Adopt a healthy diet: Focus on eating a balanced diet rich in whole grains, lean proteins, fruits, and vegetables. Avoid sugary foods and beverages, as well as foods high in unhealthy fats.

  • Increase physical activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, swimming, or cycling.

  • Lose weight if overweight: Losing even a small amount of weight can significantly reduce the risk of developing diabetes.

  • Take prescribed medications if necessary: In some cases, your healthcare provider may recommend medication to help manage your blood sugar levels.

  • Regular check-ups: Schedule regular visits with your healthcare provider to monitor your blood sugar levels and overall health.

By making these lifestyle changes and being proactive about managing your health, you can prevent or delay the onset of type 2 diabetes.
