what does impaired glucose tolerance mean

Impaired Glucose Tolerance (IGT) is a condition where blood sugar levels are higher than normal but not high enough to be classified as diabetes. It is often considered a precursor to type 2 diabetes and is diagnosed through an Oral Glucose Tolerance Test (OGTT).

Key Points:

• Definition: Blood glucose levels are elevated after consuming glucose but do not meet the criteria for diabetes.
• Diagnosis: Typically diagnosed when blood sugar levels are between 140-199 mg/dL two hours after consuming a glucose-rich drink.
• Risk Factors:
  • Overweight or obesity
  • Sedentary lifestyle
  • Family history of diabetes
  • High blood pressure or cholesterol
• Management:
  • Lifestyle Changes: Healthy diet, regular exercise, and weight loss can help prevent progression to diabetes.
  • Monitoring: Regular blood sugar checks and follow-ups with a healthcare provider.

If you have impaired glucose tolerance, it’s important to take steps to manage your blood sugar levels to reduce the risk of developing type 2 diabetes.
