Re: OB: 3 hour GTT instructions From: ainsron (ainsron@sbcglobal.net) Tue May 17 10:03:35 2005 Messages sorted by: [ date ][ thread ][ subject ][ author ] Next message: ainsron: "Sex-Slave Win Leads to Malpractice Suit" Previous message: Elrod Darryl G MAJ 48 MDOS/SGOBO: "Re: OB: 3 hour GTT instructions" In reply to: R. Daniel Braun: "Re: OB: 3 hour GTT instructions" Most articles I have read suggest the increased incidence of gestational diabetes is due to more universal screening by obstetricians and the epidemic of obesity in our patient populations. No matter what procedure or criteria you use to make the diagnosis, you are going to have false positives and false negatives, in fact there is not a consensus as to what threshold values to use for the diagnosis of gestational DM. Williams points out that for the 50-g screen, 90% of normal tests were reproducible the next day but only 83% of abnormal tests were reproducible. Catalano (1993) found that the 100-g 3 hour test was not reproducible in 25% of women when repeated one week after the initial test. They attributed it to increased norepinephrine mediated gluconeogenesis due to maternal stress at initial testing, not poor CHO loading prior to the test. In fact, Williams does not make a point of CHO loading 3 days before testing either. Ronald E.

Maybe that is the reason for the increased incidence of GDM over the last 2 decades.

They are still asking women if they have done the prescribed diet. We haven't done any diet either for several years.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
