What you drink matters as much as what you eat with gestational diabetes. Many beverages hide significant sugar, while others can help keep you hydrated and satisfied.

Best Beverages for GD

Water

  • Best choice - drink plenty!
  • Aim for 8-12 cups daily during pregnancy
  • Add lemon, cucumber, or mint for flavor
  • Sparkling water is fine

Coffee (Unsweetened)

  • Limit caffeine to 200mg daily
  • Avoid sugary coffee drinks (Frappuccinos have 50g+ sugar)
  • Use unsweetened milk or cream

Tea

  • Unsweetened tea: Zero carbs
  • Herbal teas mostly safe (check with provider)

  • Avoid sweet tea

Unsweetened Milk Alternatives

Beverages to Avoid

Fruit Juice

  • 8oz orange juice: 26g sugar

Soda

Frequently Asked Questions

Can I drink coffee with gestational diabetes?

Yes, in moderation. Coffee itself has zero carbs and won't spike blood sugar. The concern is caffeine intake during pregnancy - limit to 200mg daily (about one 12oz cup of coffee). Avoid sweetened coffee drinks which can have 40+ grams of sugar.

Why is fruit juice bad for gestational diabetes?

Fruit juice removes all the fiber from fruit while concentrating the sugar. A small 8oz glass of orange juice has 26g of sugar that hits your bloodstream immediately - comparable to drinking soda. Whole fruits are always a better choice.
