Diabetes Diagnosis
A test for
diabetes is usually prompted by one
or more of the outward
symptoms such as excessive urination
and excessive thirst.
But diabetes diagnosis is one of number of standard tests
during many types of ordinary healthchecks or medical
investigations, so you may be checked for diabetes at any
time.
If you are over 45 or so (or if you have one
or more of the diabetes risk factors) then you should consider
asking your doctor for a diabetes check if you haven't had one
recently — a positive diabetes diagnosis before it's had chance
to do any damage could save your life.
Diabetes Mellitus Types 1 and 2
The proper, full, name for Diabetes Types 1 and
2 is "Diabetes Mellitus Types 1 and 2", but
most people just refer to Type 1 or Type 2.
Tests for Diabetes Mellitus include:
-
Fasting Plasma Glucose
Test (usually shortened to FPG or FGT): a
blood test after not eating or drinking for at least 8
hours
-
Oral Glucose Tolerance
Test (shortened to OGTT): a blood test after
drinking a glucose-rich drink.
A diagnosis session usually
looks for one of the following:
-
Fasting Plasma
Glucose level greater than 125 mg/dl
(7.0 mmol/l)
-
Plasma
glucose level greater than 200 mg/dl (11.1 mmol/l) two
hours after eating 75g of glucose
-
Random
plasma glucose test greater than 200 mg/dl (11.1
mmol/l)
If there is any uncertainty then the test
will be repeated another day. FPG is preferred by doctors
because it is quick and convenient; and two positive results
for FPG means you have diabetes.
Gestational DiabetesSome time late in the
second trimester of your pregnancy, your
healthcare professional will usually ensure you are tested for
Gestational Diabetes as
a matter of course (there is no point testing earlier than
this). However because all
pregnancies (even for those Mothers without diabetes) affect
the level of sugar in your blood, the medical community is
currently discussing how high the blood sugar has to be before
they can make a firm diagnosis of gestational diabetes.
Pre-Diabetes
The tests for Pre-Diabetes uses the same
tests as for Diabetes Mellitus (above), and a diagnosis session
looks for the following:
-
OGTT results between 140
mg/dl and 200 mg/dl (or 7.8mmol/l and 11.1 mmol/l)
imply you have Pre-Diabetes; if your level for OGTT is
greater than 200 mg/dl (11.1 mmol/l) then you probably
have full diabetes.
-
FPG results between 100
mg/dl and 125 mg/dl (or 6.1 mmol/l and 7.0 mmol/l) mean
you have Pre-Diabetes. If your result is greater than
125 mg/dl (7.0 mmol/l) then you usually have another
test; if that level is confirmed that implies you have
full diabetes.
Diabetes Insipidus
Tests for Diabetes Insipidus include blood
and urine tests to test glucose, bicarbonate, and calcium
levels; also, a fluid deprivation test finds out whether it is
caused by excessive intake of liquid, insufficient levels of
ADH, or a defective response in your kidneys.
Afterwards
So you have been diagnosed with diabetes. If
you have Type 1 or 2 you will have to get your head around the
fact that you will be diabetic for the rest of your
life. You may feel a wide variety of emotions in the first
few weeks as you come to terms with your condition. But you
must remember: even though you will probably have to make some
changes to your lifestyle, you can still live a full and happy
life; and you will be assigned to a team of healthcare
professionals who will help you through the early days and
provide support for the
rest of your life.
