Pregnancy: High-Normal Blood Sugar Risky

May 7, 2008 — Babies born to women with indeed marginally higher-than-normal blood sugar levels are at increased chance for a extend of pregnancy and delivery-related complications, findings from an worldwide study confirm.

The expansive think about inspected the risks related with having elevated blood sugar during pregnancy that’s not high enough to be considered gestational diabetes.

More than 25,000 pregnant ladies from nine countries took part within the Hyperglycemia and Adverse Pregnancy Result (HAPO) ponder, which appears in the May 8 issue of The New England Diary of Medication and was largely supported by the National Organizing of Wellbeing.

Indeed a little rise in blood sugar over what is considered normal was related with an increment in antagonistic results, counting tall birth weight, C-section delivery, and preeclampsia, a complication that can lead to untimely birth and can be dangerous in case not treated.

The discoveries make it clear that hoisted blood sugar contains a direct negative impact on pregnancy and delivery, consider co-author Donald R. Coustan, MD, tells WebMD.

Coustan is professor and chairman of obstetrics and gynecology at Brown College Therapeutic School.

“This lays to rest numerous of the criticisms about gestational diabetes treatment,” Coustan says. “The critics have said that it isn’t raised glucose that leads to negative results, it is weight or maternal age or some other risk figure. But we were able to control for these risk factors, and glucose was still a major determinant of outcomes.”

Who Ought to Be Treated?

One critical question that remains unanswered is whether the limit for treating high blood sugar in pregnancy ought to be brought down and in the event that so, by how much.

“Because there was a continuous relationship that was indeed seen in women with glucose levels considered near ordinary, this study isn’t very helpful for attempting to pinpoint where the cutoff ought to be,” Coustan says.

In a piece going with the ponder, diabetes researchers Jeffrey Ecker, MD, and Michael Greene, MD, of Harvard Therapeutic School, conclude that the current evidence does not back bringing down the edge for gestational diabetes determination and treatment.

While ladies within the HAPO trial with higher blood sugar levels moreover had higher rates of conveying high birth-weight babies, they also gave birth to fewer babies who were small for their gestational age.

And whereas C-section rates expanded with expanding blood sugar in the HAPO consider, the increment was modest. Treatment to lower blood sugar levels was found to have no affect on C-section conveyances in a similar study of pregnant women with high-normal blood sugar.

“Until trials show clinical benefits for growing the symptomatic criteria for ‘gestational diabetes,’ we would not favor any change,” Ecker and Greene compose.

Next month, an internationally agent bunch of diabetes, pregnancy, and open health experts will meet in Pasadena, Calif., to create their claim assessment.

“Right presently, there is a add up to lack of assention approximately what ought to be called gestational diabetes and who ought to be treated,” HAPO venture supervisor Lynn P. Lowe, PhD, of Northwestern University tells WebMD.

Is Metformin Safe?

There is also disarray around which blood sugar-lowering therapies are best for the treatment of gestational diabetes.

Affront is frequently recommended when count calories and work out alone fall flat to lower blood sugar, but use of the broadly endorsed diabetes medicate metformin amid pregnancy remains disputable.

In a isolated study moreover reported in Thursday’s Modern England Journal of Medication, analysts compared results in 751 women with gestational diabetes treated with either affront or metformin.

Analyst Janet A. Rowan, MB, and colleagues detailed no increment in complications among infants born to mothers who took metformin.

But almost half (46%) of the metformin-treated ladies finished up needing supplemental insulin.
