Jeannie is right on the money. You are worrying to much and taking to many readings. Your critical reading is the fasting reading and that is normal, normal, normal. Your postprandial is also normal at 130-140. The ONLY reason many of us who are diabetic do that postprandial reading is to see how badly we are spiking as it is the spikes that can do us damage, especially if they don't recede fairly quickly. YOU have no such problem with those numbers.
Enjoy life and don't worry unless those fasting numbers start to consistently be above 120.
PS - here is an illustration of why a diabetic needs to do a number of readings until they are certain they are under control. Fasting =100 3 hours after eating = 145 BUT
heres what really happened to that diabetic. 15 mins after Lunch = 245 30 mins after lunch=220 45 mins = 215
1hr = 210 1.5hrs = 200 2hrs=190 2.25 hrs=180 2.5hrs=160 2.75hrs=152 3hrs=145
Now that huge spike with sustained levels above 180 can hurt you. If this person had taken only one reading 3 hours after eating and one in the morning after fasting, well, they would appear normal when actually they had a problem that should be addressed. You on the other hand, eating chinese food with all the fat from the oil and the white rice; well that meal would have sent the BS of a diabetic skyrocketing, but obviously, your endorcrine system rallied and you produce really normal BS. So did all that testing tell you something? YES, as Jeannie said, stop doing so many tests and stop worrrying. Live a healthy lifestyle but your body is telling you that you don't need to be so vigilent.
Please also realize that if you really stress out about this stuff, it can physically affect your blood pressure and BS readings.
