Hi,
Have you got a Glucose meter that you can use to monitor your fasting,
1 & 2 hour post meal numbers, that you could log and show your doctor
to give him (her?) a real time example of what is going on with you.
It might give the doc the kick in the tush needed to send you in for a
OGTT or possibly give you the peace of mind that comes from knowing
that things are okay.

A lot of folks who don't have insurance to back them up use the
Walmart brand Relion Ultima as the meter itself costs less than ten
bucks and 100 strips for under $50.  My understanding is that while it
doesn't have a lot of bells and whistles, it is pretty accurate and
might fit your need.

Just a thought.

  The OGTT consists of taking 75 gram of glucose on a fasting stomach with
300 ml or so of fluid,   then checking your blood sugar over a 2 hour
period.

If you can get your hands on 75 gram of glucose and a home blood sugar
testing meter,   (Wal-Mart Relion house brands are cheap and "good enough" )
you can do your own OGTT.    You won't do as good a job as the medical pro's
but the data might either reduce your anxiety or convince your doctor.

You can buy "weighed" glucose tabs OTC at most pharmacies.

Note that some folks find OGTT to be a very unpleasant experience.

The fellow who put this web site together has a few odd opinions but his raw
data are taken from good medical reports.

FWIW,  FbG can be an unreliable indicator.   AIUI,   the European medical
community prefers to interpret after-eating sugars,   the U.S. community
prefers FbG,  but both regard OGTT as a definitive standard.

Although I had a T2 diabetic mother, my doctor kept telling me don't
worry, you're not yet diabetic, because I was a) not fat, b) not
pissing sugar, c) my random blood sample taken when I turned up in his
surgery were fine, and d) when I made a fuss and he checked my fbg,
that was fine too. Why did I mkae a fuss? Because I was already
showing some symptoms consistent with diabetes, such as peripheral
neuropathy, confusion and drowsiness after meals, and a heart
attack. But according to my doc these were all more easily explained
by the simple fact that I was suffering from age. He could tell that
from my date of birth. No need to suggest the unlikely possibility of
diabetes, unlikely because I wasn't fat etc..

Then I bought a cheap BG meter and made a graph of my BG response to
my healthy breakfast of muesli with milk and no added sugar or
fruit. I showed it to my doctor. He explained that I must be one of
those untypical diabetics who have ok fbgs and aren't fat.

Incidentally, once I discovered I was diabetic and started controlling
my BGs by diet (I was already exercising to keep the heart problems at
bay), many of those symptoms of age I'd been suffering from started to
improve. Including the heart problems. Exercise and medication had
helped a bit, but adapting my already heart-healthy diet in the
direction of a low-spike diet with the aid of my meter made a lot
faster anf bigger improvement in my cardiac symptoms than the previous
treatment by exercise, medication, and a heart-healthy diet. Stripping
the BG spiking carbs out of my already heart-healthy diet were what
made the biggest improvement.

I would definitely press for the OGTT.  In "most" (but not) Type 2's, the
post-prandial sugars show abnormalities before the FBG.  I am a case in
point.  My FBG runs about 90, however, if I eat a starchy food--bread, rice,
fruit juice--my post-prandial sugar will spike at 180 at 1 hr.  It then
falls to below 140 at the 2 hour mark.  Before I eliminated the foods that
caused that spike from my diet, I felt pretty crappy.  I was tired all the
time, and hungry all the time.  I feel so much better on the controlled
diet.

If your doctor refuses the OGTT, then I would suggest that you get a
glucometer and test yourself.  This is what I did.  Then if you find that
your post-prandial sugars are abnormal, you've got information to give to
your doctor so that he/she can see what you're talking about.
