Gestational diabetes: understanding and managing during pregnancy

IRIS Prévention
17 March 2027
Gestational diabetes is not inevitable for pregnancy: if detected and monitored, it is managed well and most often disappears after birth.

Discovering diabetes during pregnancy can be worrying. However, gestational diabetes is common and, in the vast majority of cases, it is managed effectively through diet and monitoring. Properly taken care of, it allows for a peaceful pregnancy and childbirth. Let's take stock.

1. What is gestational diabetes?

This is an increase in blood sugar levels that appears during pregnancy, most often in the second trimester, due to hormonal changes. It generally disappears after childbirth, but deserves treatment during pregnancy.

2. How is it detected?

Screening is offered during pregnancy, particularly in the presence of risk factors (overweight, family or personal history, age). It is based on blood sugar measurements, sometimes after absorption of sugar. Early diagnosis allows you to act quickly.

3. Support

In most cases, an adaptation of diet and appropriate physical activity are enough to balance blood sugar levels. Self-monitoring is put in place. If necessary, treatment can be added. Follow-up is provided by the medical team.

    • Adapt your diet (distribution of carbohydrates)
    • Maintain appropriate physical activity
    • Monitor your blood sugar as recommended

4. After childbirth

Gestational diabetes usually goes away after birth, but it increases the risk of developing type 2 diabetes later. Follow-up is therefore recommended after childbirth, and healthy lifestyle remains important for prevention.

Well supported, gestational diabetes can be managed peacefully. Medical monitoring is essential throughout pregnancy and after.
