Diet to prevent gestational diabetes

Gestational diabetes develops when pregnancy-related changes make it harder for the body to keep blood glucose in its usual range. It can happen even when someone eats carefully and is active. Blame or strict restriction is unhelpful, and pregnancy is not the time for weight-loss dieting unless a maternity professional gives specific advice.

Screening can find raised glucose before obvious symptoms appear. Your maternity team may use an oral glucose tolerance test and then discuss monitoring or treatment if needed.

Choose vegetables, fruit, beans, whole grains, and protein foods such as eggs, fish, poultry, yoghurt, tofu, or lentils. Spread carbohydrate foods across meals and snacks instead of relying on sugary drinks, sweets, or large portions of refined starch. Water is a useful everyday drink. Keep meals enjoyable and culturally familiar, and ask for an individual plan if you have nausea, food allergies, diabetes before pregnancy, or another medical condition.

Attend antenatal appointments and complete screening when offered. If gestational diabetes is diagnosed, follow the monitoring plan; diet advice may then be adjusted to your readings and baby's growth.

Contact your maternity service if you cannot keep fluids down, feel faint or very unwell, notice reduced fetal movement, or have concerns about high glucose readings after monitoring has started. Seek urgent assessment for severe headache, vision changes, heavy bleeding, severe abdominal pain, or sudden breathlessness.

Ask when screening is due, how to prepare for the glucose tolerance test, which carbohydrate portions suit you, and whether a dietitian or additional growth monitoring is needed.
