Hello doctor,

I got my blood test results today. My fasting blood sugar is 97 mg/dL. But, my HbA1c is 6.89 with mean blood glucose at 144. I am going through premenopause and I am 49 years old female. Please help.

  • This is suggestive of a possible impaired glucose tolerance (IGT). I would suggest getting an oral glucose tolerance test (OGTT).
  • While many do consider it out of date, I think in your case it would yield the diagnosis.
  • Upload the report for further suggestions. Meanwhile, start diabetic diet. Avoid sugar and high carbohydrate diet.

Hello doctor,

Over the last three months, I have been pretty stressful since my daughter got married 33 days back. Will this have any effect on the test? Does this mean that I am diabetic or a high disposition to diabetes?



Welcome back to

  • If the OGTT comes out to be positive, then you may be a diabetic.
  • As of now, I would suggest that you have a predilection for diabetes.
  • However, high calorie diet may have influenced HbA1c (glycated hemoglobin), in which case OGTT should be normal.
  • Stress as such would not cause this.
