How Much Water Do I Really Need? What to Know About Pregnancy Hydration

We're diving into the essential topic of hydration during pregnancy. Believe us we know that getting enough water isn't always easy in many of our busy lives, but avoiding dehydration while pregnant is something to put high on your to-do list. 

Forget just eating for two, it's time to start drinking for two. Here's your comprehensive guide to keeping your pregnant body hydrated and your baby-to-be thriving.

Why is Drinking Water So Important During Pregnancy?

Water isn't just important, it's vital for life, and during pregnancy your body needs even more of it.  Here's what proper hydration is doing for you and your little one:

  • Forming the amniotic fluid around your baby
  • Producing extra blood (hello, pregnancy glow!)
  • Building new tissue
  • Reducing pregnancy-related swelling
  • Helping prevent constipation and hemorrhoids
  • Decreasing the chance of urinary tract infections
  • Potentially lowering the risk of preterm labor and birth

Water is working overtime to keep you and your baby healthy.

How Much Water Should You Drink Per Day While Pregnant?

Time for some pregnancy math (don't worry, it's the easy kind). Experts recommend 8 to 12 cups of fluids daily. That's about 64 to 96 ounces, or 1.9 to 2.8 liters.

But you also need to know that your fluid needs change as your bump grows:

  • First trimester: Focus on sipping what you can, especially if morning sickness is an issue.
  • Second trimester: Add an extra 340 milliliters (about 11.5 ounces) to your daily intake.
  • Third trimester: Bump it up with an additional 450 milliliters (about 15 ounces).

Beyond just your water needs, you need to make sure you are supporting your bodies electrolytes, especially when you are more thirsty than normal.

Hydration for Breastfeeding Moms

Planning to breastfeed? Your hydration journey is far from over, your body still needs more than normal. In fact you should aim for about 128 ounces (3.8 liters or 16 cups) a day to keep your milk supply strong and your energy up. Remember, you lose about 25 ounces of water in breast milk every day.

Dangers of Dehydration In Pregnancy

Let's get real—dehydration during pregnancy is not just uncomfortable, it can be downright dangerous. Here's what could happen if you let your hydration slide:

  • Reduced growth for your baby (affecting weight, head circumference, and length)
  • Dizziness and weakness
  • Low blood pressure (hypotension)
  • Potential need for hospitalization and IV fluids

Signs of Dehydration While Pregnant

Your amazing pregnant body has ways of telling you it needs more H2O. Keep an eye out for these dehydration red flags:

  • Dark-colored urine
  • Less frequent urination
  • Extreme thirst
  • Dizziness
  • Fatigue
  • Confusion

When Are You at Higher Risk of Dehydration?

Some situations call for extra H2O attention:

  • During workouts - yes, even prenatal yoga.
  • In hot weather - beach babymoon or just a hot afternoon at home.

  • When you're dealing with sickness and diarrhea - which unfortunately are common in pregnancy.
