Hi. When it's in the 80's are you having any symptoms like hunger, sweating, faint feeling, etc?
Customer: replied 2 years ago.
No i didn't
Expert:  Dr. Chip replied 2 years ago.

OK. First off there may not be a problem at all here, but you may be having what's called reactive hypoglycemia--excess insulin secreted after a meal.

True reactive hypoglycemia causes the symptoms I mentioned and the blood glucose usually drops into the 70's or 60's with that.

While I don't think this is a problem you should discuss this with your doctor and get a HGB A1C test and a glucose tolerance test since reactive hypoglycemia, in time, may turn into diabetes

Let me know if you need any more information please

You mean that i have diabetes now .
I checked yesterday 2 hours after my lunch & it was 92 .
then i did A1C test since about 4 months & it was good .
Expert:  Dr. Chip replied 2 years ago.
No, you don't have diabtes now but you may get it in the future so it would be best to get the glucose tolerance test or at least discuss this with your doctor.
Customer: replied 2 years ago.
What is hypoglycemia? & why you diagnosed me that i may i have it .
Expert:  Dr. Chip replied 2 years ago.

Low blood sugar. I'm not saying for sure you have reactive hypoglycemia but since your blood sugar sometimes drops after eating you may so that's why I say at least tell your doctor about the drop

Customer: replied 2 years ago.
But it not dropped it is still within the normal limit . Which is 80 to 140 for post prandial test .
Expert:  Dr. Chip replied 2 years ago.

Yes but it really shouldn't drop that far two hours after eating, even if it is still withing normal limits.

As I said at the beginning there may be absolutely nothing abnormal about this but still you should at least discuss it with your doctor
