Why diet and exercise may not be enough to prevent GDM

All women should be screened earlier for dysglycaemia, urge US researchers

Dieting and exercise may not stop the onset of gestational diabetes mellitus (GDM), say US researchers, who suggest early screening for dysglycaemia in all women may prove a more effective prevention strategy.

The study of 62 obese pregnant women over 12 weeks in their second trimester found the energy balance (intake vs expenditure) was similar in the nine women who developed GDM compared with the rest of the participants.
