New research presented in Milan indicates women with history of gestational diabetes are diagnosed with type 2 diabetes earlier and may experience more severe disease, highlighting the need for long-term monitoring.
New research to be presented at the European Association for the Study of Diabetes meeting in Milan suggests that women who develop type 2 diabetes after gestational diabetes tend to be diagnosed much earlier and appear to have more advanced disease than women with no such pregnancy history. In the Danish analysis, women with prior gestational diabetes were diagnosed with type 2 diabetes at a median age of 43.5, compared with 56.3 for those without it.
The findings add to a long line of evidence that gestational diabetes is not a short-lived pregnancy complication but a marker of lasting metabolic risk. A review in The Lancet and later register-based studies in Finland and Denmark have all pointed to a markedly higher chance of developing type 2 diabetes after gestational diabetes, with risk remaining elevated for years and, in some analyses, for decades.
What makes the new Danish work notable is its suggestion that the later diabetes may also be more severe. Women with a history of gestational diabetes were about twice as likely to need insulin within two years of diagnosis, and they had lower fasting C-peptide levels, which can indicate reduced insulin production. By contrast, body mass index, blood sugar control and most complication rates were broadly similar between the groups at the time of enrolment.
The researchers said the pattern points to the need for closer follow-up of women after a gestational diabetes diagnosis. That fits with earlier research suggesting that susceptibility may reflect a combination of genetic and environmental factors, and that risk can vary between population groups. Taken together, the studies reinforce a simple message: gestational diabetes should trigger long-term monitoring, not just care during pregnancy.
