What should you know about diet for gestational diabetes during third trimester?

Gestational diabetes means blood glucose is higher than the pregnancy team wants. As pregnancy progresses, insulin needs can change, so a meal pattern that worked earlier may need adjustment. Carbohydrate foods include bread, rice, pasta, potatoes, fruit, milk, and sweets; the portion and timing can affect readings.

A balanced plate can include non-starchy vegetables, a protein food, and a modest portion of carbohydrate. Fibre-rich choices and unsweetened drinks may help you feel satisfied. Avoid skipping meals or cutting out carbohydrate completely, because pregnancy still requires adequate nourishment and your team may need to review medication.

Follow the testing schedule you were given and record meals beside glucose readings so patterns are easier to discuss. Spread carbohydrate across meals and planned snacks, choose water instead of sugary drinks, and use gentle activity after eating if your maternity team says it is suitable. Bring your records to antenatal appointments; medication may be needed even when meals are carefully planned.

Contact your maternity team if readings repeatedly miss your agreed range, you cannot keep food or fluids down, or you have symptoms such as shaking, sweating, confusion, or unusual drowsiness. Seek urgent pregnancy care for reduced fetal movement, vaginal bleeding, severe headache with vision changes, or severe abdominal pain. Use the plan you were given for treating a low glucose reading.

Ask what glucose targets apply to you, how to adjust meals when appetite changes, and whether exercise is appropriate. Clarify when medication is considered, how often the baby’s growth will be checked, and which symptoms require same-day advice.
