Why cant we the gynecologist
treat GDM or DM by ourselves.
Q. 1: How to diagnose frank DM by people like us?? What are the criteria
for diagnosis of frank diabetes??
For men & non
pregnant woman what is frank Diabetes?? When GTT becomes an unnecessary investigation ?? Ans:-All values mentioned under are
the diagnostic criteria of frank DM e.g. are venous plasma true glucose values random venous plasma glucose > 200 mg % is sufficient to make diagnosis of diabetes. However the diagnostic criteria
for glucose metabolic abnormalities taken together are as
follows egg, three kinds of
abnormalities for diabetes , IFG and IGT
.
A) In a person with classical symptoms
of diabetes one reading of unequivocal hyperglycemia i.e. random venous plasma glucose > 200 mg % is sufficient to make diagnosis of diabetes. For example
if a person has polyuria ,
polydipsia, weight loss and random blood glucose is of 278 mg% he/ she is diabetic
and no other test is required to
confirm the diagnosis . In such a situation
he/ she should be treated with a consulation f diabetologists or else treated
by local doctor with 1) diet control b) Exercise
and in phases 3) Oral antidiabetic
agents like metformins, gliptins .
B) Fasting
only > 126 on two occasions? Ans;
This is also to be treated as frank DM. For instance imagine a condition
where fasting venous plasma glucose of 126 mg % on more than one occasion
then also he /she should also be considered as
frank DM ,This is sufficient for
diagnosis of diabetes even in the absence of symptoms and no PP sugar estimation is
essential for confirmation of frank DM,..
C) A two hour venous plasma glucose of 200 mg %
or more after oral glucose load of 75 g on more than one occasion is frank DM
Q. 2:- What is isolated IFG/IGT ?? Ans: If fasting venous plasma glucose level is between 100 to
126 mg% and if two
hours post 75 g glucose venous plasma glucose level
is below 140 mg
% then the condition is called impaired fasting glucose tolerance(IFT).
. What
is “impaired fasting glucose tolerance?? ::- In non diabetic persons fasting and 2 hours post oral
75 g glucose values of venous plasma glucose are in the range of 100 mg% to-125 mg% but PPBS is < 140
mg% respectively then it is
called IFG.
IFT /IGT are the
two conditions that represent an intermediary
state between normal on one side and
diabetes on the other side .
Q.3:- Why such clasifiaction ? What is the
relevance ? Ans:
Some people have isolated IFG/IGT while others have combined IFG and IGT.
As regards micro vascular complications of diabetes people in IFG and IGT
are not at significant risk and in this respect both the conditions are
equivalent. However as regards
macrovascular diseases associated with
diabetes people in IGT are at a higher risk
as compared to those in IFG
