Question: how many ml of water to drink when pregnant?
Answer: Individuals generally need 1–1.5 ml of water for each calorie consumed (e.g., a person eating a 2000-calorie diet would need 2000–3000 ml of fluid each day) (Dudek, 2001). Most pregnant women are advised to increase their caloric consumption by about 300 calories, beginning in the second trimester (Dudek, 2001).
