Individuals having either impaired fasting glucose (IFG) or impaired glucose tolerance (IGT) are considered to have blood glucose levels which are higher than normal, but below that of people classified as diabetic. If you have IGT or IFG, the likelihood of you developing diabetes is significant.

Did you know that most people having either impaired fasting glucose or impaired glucose tolerance do not exhibit signs of illness? Also, they may have normal glycohemoglobin levels. The only sure way to now is to test.

What is the fasting blood glucose test?

In this test you are required to fast 8-12 hours. Normally, the test is done first thing in the morning.

The following guidelines apply to the test:

  • Blood glucose level below 110mg/dl for a non-diabetic person.
  • A diabetic individual will have a level of 126mg/dl or above.
  • Blood glucose levels between 110 and 126mg/dl would indicate a person with impaired fasting glucose.

What is the oral glucose tolerance test?

In this test, you are required to not eat for a period of 8-12 hours. Then, your blood glucose level is measured up to give times in three hours. The next step is to consume 75 grams of oral glucose in liquid form. Once this is done, the blood glucose level is checked at 30 minutes, 60 minutes, 120 minutes, and at 3 hours.

Blood Pressure Glucose

Low Blood Pressure Will Help Your Glucose Levels

The following guidelines apply to the test:

  • 140mg/dl at two hours for non-diabetics.
  • 200mg/dl at two hours for diabetics.
  • Between 140 and 200mg/dl at two hours for a person with impaired glucose tolerance.

What is the treatment for impaired fasting glucose and impaired glucose tolerance?

Most individuals with these conditions are overweight, with high triglyceride levels, low HDL levels, and hypertension (high blood pressure.) Many people are at extreme risks for heart disease.

Steps you can take to bring blood glucose levels to normal:

  • Lose weight
  • Lower your triglyceride intake
  • Lower your cholesterol levels
  • Work to achieve normal blood pressure (diet, exercise, medication)
  • Increase exercise and activity
  • Improve your diet and eat healthier foods

Here are some other names for IFG and IGT:

  1. “Touch of sugar”
  2. Borderline diabetic
  3. Chemical diabetes
  4. Latent diabetes
  5. Potential diabetes
  6. Pre-diabetes
  7. Subclinical diabetes
