Most expecting mothers are well aware of the need to stay hydrated during pregnancy. After all, your baby is literally swimming in the fluids you’re passing on to them in the form of amniotic fluid. But hydration does so much more than just keeping your baby comfortable in the womb. It plays a critical role in supporting your own health throughout the pregnancy, helping to ease common pregnancy discomforts, and even improving the quality of your ultrasound images. Let’s dive into why drinking water is so vital during pregnancy and how much you should aim to drink every day.

The Role of Water in Pregnancy

Water is not just a beverage—it's a lifeline for both you and your baby during pregnancy. Your body undergoes a lot of changes, and water plays a huge part in helping your systems adapt to the increasing demands of pregnancy. Let’s look at some of these demands.

Maintaining Increased Blood Volume & Circulatory Health

One of the first things that changes when you’re pregnant is your blood volume. By the time you’re in your second trimester, you may have up to 50% more blood circulating through your system. This means your circulatory system needs to work harder to pump this extra blood, and staying hydrated is crucial to making sure it runs efficiently. Think of it like drinking water through a straw versus trying to drink a milkshake. Hydration helps keep your blood "thinner" and flowing easily, reducing the strain on your heart and blood vessels. This means less pressure on your body’s cardiovascular system, and more energy for you to go about your day!

Create and Maintain Amniotic Fluid Levels

The amniotic fluid is the liquid that surrounds your baby in the womb, providing protection, cushioning, and the ideal environment for growth and development. Adequate hydration helps ensure that your baby has enough amniotic fluid. This fluid is what allows babies to be imaged in 3D/4D. Good hydration before an ultrasound ensures clearer, more detailed images of your baby, so you get a better view of those adorable features—who doesn’t want that?

When preparing for your session keep in mind that hydration takes time—so guzzling water the day before your scan won’t do much for the clarity or the amount of fluid. It’s a good idea to focus on consistent hydration throughout your pregnancy. And while we’re talking about water, let’s clear up a little myth: a full bladder might be necessary for some ultrasounds, but it’s not the same as being hydrated.

Water can Ease Common Pregnancy Discomforts

From headaches to leg cramps and constipation, pregnancy can come with a variety of uncomfortable symptoms. The good news is that water is a quick fix for many of these issues! Staying hydrated helps alleviate constipation by softening stools, reducing the likelihood of painful cramps and bloating. It can also help relieve leg cramps, which are common in the later stages of pregnancy. And, of course, water helps to prevent dehydration-related headaches, which many women experience due to hormonal changes. So, when you feel those annoying pregnancy symptoms coming on, reach for some good old water, you might be surprised how better being hydrated can make you feel.

Preventing Urinary Tract Infections (UTIs)

Pregnant women are at a higher risk for urinary tract infections due to changes is the natural PH balance during pregnancy. Drinking plenty of water helps flush out bacteria from your urinary tract, reducing your chances of developing a UTI. So, sipping on water regularly can be an easy yet effective way to keep your urinary system in good shape throughout your pregnancy.

How Much Water to Drink During Pregnancy

It’s always good to get your doctor’s advice on the optimal amount of water for you. The amount of water you need can vary depending on factors like regional heat, activity level, age, and maternal weight and height. On average, aiming for 100 ounces of water per day is a good starting point. That’s roughly 2.5 liters or about 12 cups of water. If you are drinking from a Stanley cup and you fill the cup with ice, make sure you are volume testing your intake, so you are not fooled into thinking because you are drinking from a 32oz cup you are drinking 32oz. If that cup starts full of ice, you may only be getting about 16oz.

It’s also important to remember that while drinking water is key, not all fluids are created equal. Be cautious of sugary drinks or caffeinated beverages, which can actually dehydrate you. Electrolyte imbalances can also cause your body to lose fluids more quickly, so make sure you’re getting the right balance. It’s not just about the volume of water—it’s about quality too. Both soda and caffeinated drinks (including coffee and tea) can have a diuretic effect, which means they encourage your body to eliminate water through urine. This can lead to dehydration, especially if you're not drinking enough water to compensate. So please be mindful that these drinks while they feel like they quench your thirst are actually causing dehydration.

Tips to Stay Hydrated

Here are a few tips to help you drink more water throughout the day:  

• Carry a water bottle with you.  Having a bottle on hand makes it easier to remember to drink.
• Add some flavor – If plain water doesn’t excite you, try adding a slice of lemon, cucumber, or mint for a refreshing twist.
• Set reminders – Pregnancy brain can sometimes make you forget to hydrate, so set a timer or reminder to drink water every hour.
• Monitor your urine color – Pale yellow urine is a sign of good hydration, while dark yellow or amber means you need to drink more water.

The bottom line is clear: staying hydrated during pregnancy is one of the simplest yet most effective ways to support your health and your baby’s development. From enhancing amniotic fluid levels to easing pregnancy discomforts, water truly is your best friend during this journey.
