- Question
- Are there effective long-term pharmacological interventions to prevent the onset of type 2
diabetes that can be recommended postnatally for women who have been diagnosed with
gestational diabetes? - Any explanatory notes
(if applicable) - Gestational diabetes is one of the strongest risk factors for the subsequent development of type 2
diabetes: up to 50% of women diagnosed with gestational diabetes develop type 2 diabetes within
5 years of the birth. There are some data suggesting that changes in diet and exercise, with or
without metformin, can prevent type 2 diabetes developing in non-pregnant middle-aged people
with glucose intolerance, but there are no studies specifically in women with a past history of
gestational diabetes. There is thus an urgent need to investigate what interventions may delay or
prevent type 2 diabetes developing in this high-risk population of women. Undertaking a formal
randomised controlled trial involving long-term outcomes is often not feasible in practice.
However, it would be possible to have a quasi-randomised study comparing 2 populations of
women with similar demographic profiles who had gestational diabetes. One population would be
encouraged at their annual check to follow a specific diet and exercise regime and those in the
other population would not. The incidence of the development of type 2 diabetes in the 2 groups at
5, 10 and 20 years would be compared.
