Greetings to all the expecting mothers out there! Pregnancy is a beautiful journey but can also be physically demanding. With so much happening inside your body, it is essential to stay hydrated. Water is vital for every living being, and the need increases during pregnancy. However, the question that arises is how much water should you drink while pregnant? In this article, we will discuss in detail all the aspects of water intake during pregnancy.

Why is Water Important During Pregnancy?

Water is crucial during pregnancy as it:

  • Helps in the formation of the placenta and amniotic fluid, which protects the baby
  • Helps transport nutrients and oxygen to the baby
  • Prevents constipation, which is common during pregnancy

  • Prevents dehydration, which can lead to preterm labor and other complications

How Much Water Should You Drink While Pregnant?

The American College of Obstetricians and Gynecologists (ACOG) recommends drinking at least eight to twelve 8-ounce glasses of water every day during pregnancy. However, this is just a general guideline, and the amount of water required may vary depending on various factors such as:

  • The mother’s body weight and height
  • The climate and weather conditions
  • The mother’s physical activity level
