Prediabetes

What is prediabetes and how is it different from diabetes?

Prediabetes is the state that occurs when a person’s blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes. About 10 percent of people with prediabetes develop type 2 diabetes each year over next 3 years.

 

Is prediabetes the same as Impaired Glucose Tolerance or Impaired Fasting Glucose?

Yes. Doctors sometimes refer to this state of elevated blood glucose levels as Impaired Glucose Tolerance or Impaired Fasting Glucose (IGT/IFG), depending on which test was used to detect it.

 

What problems can arise from prediabetes?                                                                                                                                         

People with prediabetes are at higher risk of cardiovascular disease (e.g. heart disease, stroke etc.). People with prediabetes have a 1.5-fold risk of cardiovascular disease compared to people with normal blood glucose. People with diabetes have a 2- to 4-fold increased risk of cardiovascular disease. We now know that people with prediabetes can delay or prevent the onset of type 2 diabetes through lifestyle changes.

 

Why do I need to know if I have prediabetes?

If you have prediabetes, you can and should do something about it. Studies have shown that people with prediabetes can prevent or delay the development of type 2 diabetes by up to 58 percent through changes to their lifestyle that include modest weight loss and regular exercise. The experts recommends that people with prediabetes reduce their weight by 5-10 percent and participate in some type of modest physical activity for 30 minutes daily. For some people with prediabetes, intervening early can actually turn back the clock and return elevated blood glucose levels to the normal range.

 

What is the treatment for prediabetes?

Treatment consists of losing a modest amount of weight (5-10 percent of total body weight) through diet and moderate exercise, such as walking, 30 minutes a day, 5 days a week. Don’t worry if you can’t get to your ideal body weight. A loss of just 10 to 15 pounds can make a huge difference. If you have prediabetes, you are at a 50 percent increased risk for heart disease or stroke, so your doctor may wish to treat or counsel you about cardiovascular risk factors, such as tobacco use, high blood pressure, and high cholesterol.

 

 Could I have prediabetes and not know it?
Absolutely. People with prediabetes don’t often have symptoms. In fact, millions of people have diabetes and don’t know it because symptoms develop so gradually, people often don’t recognize them. Some people have no symptoms at all. Symptoms of diabetes include unusual thirst, a frequent desire to urinate, blurred vision, or a feeling of being tired most of the time for no apparent reason.
