what is impaired glucose tolerance

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 eating but not high enough to meet the criteria for diabetes.
• Diagnosis: Typically diagnosed when blood glucose levels are between 140-199 mg/dL 2 hours after consuming a glucose-rich drink during an OGTT.
• 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-up with a healthcare provider.

If you have IGT, it's important to take steps to manage your condition and reduce the risk of developing type 2 diabetes.
