Quick Summary
- Staying hydrated during pregnancy is important for both you and your growing baby.
- Pregnancy increases your body’s fluid needs, although the amount can vary from person to person.
- Your water needs may increase during hot weather, physical activity, or if you’re experiencing vomiting or diarrhea.
- Dehydration can sometimes cause symptoms like dark urine, dizziness, dry mouth, and unusual tiredness.
- This guide explains how much water you generally need, what drinks can support hydration, and simple tips to make drinking enough fluids easier during pregnancy.
Introduction
During my pregnancies, I was often confused about whether I was drinking enough water. Some days I felt thirsty all the time, while on other days I barely felt thirsty at all. I still remember my first trimester when drinking water sometimes made my morning sickness feel worse. Even then, I knew I needed to stay hydrated, which wasn’t always as easy as I expected.
At first, I thought drinking water was simply about satisfying my thirst. Later, after speaking with my doctor, I learned that staying hydrated supports both the mother and the baby in many ways. It plays an important role in digestion, circulation, maintaining amniotic fluid levels, and helping your body adapt to the many changes that happen during pregnancy.
If you have similar questions about pregnancy hydration, you are not alone.
In this guide, I’ll answer some of the most common questions about pregnancy hydration, including how much water pregnant women generally need, the signs of dehydration, and practical tips to make staying hydrated easier throughout pregnancy.
Staying hydrated is also easier when you follow a balanced pregnancy diet. If you’re wondering what foods to eat during each trimester, you may find our Pregnancy Diet Chart: Healthy Meal Plan for First, Second & Third Trimester helpful.
How Much Water Should You Drink During Pregnancy?
As a general guideline, the total amount of water needed during pregnancy is often described as approximately 2.3 liters (about 10 cups) per day from beverages and food combined. This is not a strict requirement for every pregnant woman, and individual fluid needs can vary depending on factors such as activity level, weather, pregnancy symptoms, and overall health.
Your healthcare provider may recommend different amounts based on your individual needs.
Your daily fluid intake can come from a variety of sources, including:
- Plain water
- Milk
- Soups
- Smoothies
- Fruits
- Vegetables
- Other non-alcoholic beverages
Your fluid needs may be higher or lower depending on factors such as:
- Weather and temperature
- Physical activity levels
- Your body weight
- Vomiting or diarrhea
- Fever
- Your overall health
Instead of focusing on one exact number, try to drink fluids regularly throughout the day and pay attention to your body’s thirst signals.
Drinking small amounts frequently may feel more comfortable than drinking large amounts at once, especially if you’re experiencing morning sickness and heartburn during pregnancy.
Is 8 Glasses of Water Enough During Pregnancy?
Before I became pregnant, I always heard that everyone should drink 8 glasses of water a day. Naturally, I assumed that the same advice applied during pregnancy. However, I soon realized that staying hydrated during pregnancy isn’t about reaching one specific number every day.
I noticed that my fluid needs changed from day to day, which is common during pregnancy. Listening to my body’s needs worked much better than trying to force myself to drink a specific number of glasses every day.
The popular “8 glasses a day” rule can be a useful reminder to drink enough fluids, but it isn’t a universal pregnancy recommendation. Some women may need more fluids, while others may feel more comfortable drinking smaller amounts more frequently throughout the day.
Rather than focusing only on counting glasses of water, pay attention to how you feel and make hydration a regular habit. If you’re unsure whether you’re drinking enough during pregnancy, your healthcare provider can offer personalized guidance based on your individual needs.
Why Is Hydration Important During Pregnancy?
Water plays an important role in many of your body’s normal functions. During pregnancy, staying hydrated not only supports your overall health but may also help manage some common pregnancy discomforts.
It Helps Support Your Increased Blood Volume
During pregnancy, your body produces more blood to support both you and your growing baby. Drinking enough fluids helps support normal blood circulation and allows your body to adapt to the many changes that happen throughout pregnancy.
It May Help Prevent Dehydration
Pregnancy symptoms such as nausea, morning sickness, sweating, vomiting, and illness can increase fluid loss. Drinking enough water and other fluids throughout the day can help replace the fluids your body loses and support healthy hydration levels.
It Supports Healthy Digestion
Constipation was one of the most uncomfortable symptoms I experienced during pregnancy, especially during my first trimester. I found that eating fiber-rich foods along with drinking enough water helped support healthy digestion and made constipation easier to manage.

It May Help with Pregnancy Fatigue
Dehydration can sometimes contribute to feelings of tiredness and generally feeling unwell. While drinking water is not a cure for pregnancy fatigue, staying well hydrated is one important part of supporting your overall health and energy levels during pregnancy.
It Supports Your Body as Your Baby Grows
Throughout pregnancy, your body needs fluids for many important processes. Staying hydrated is one of the simplest daily habits that can support your overall well-being while your baby continues to grow and develop.
How Much Water Should You Drink During Each Trimester?
You don’t necessarily need to drink the exact same amount of fluids during every trimester. Pregnancy symptoms and lifestyle changes may affect how much you feel comfortable drinking and how much fluid your body needs.
First Trimester
The first trimester is the period when many women find it difficult to drink enough water because of morning sickness and nausea.
I still remember that drinking plain water sometimes made my nausea feel worse. Even then, staying hydrated remained important.
If you’re unable to drink plain water comfortably, don’t worry. Taking small sips throughout the day may feel easier than drinking large amounts at once. Some women may also find cold water, lemon water, or lemon tea easier to tolerate during the first trimester.
You can:
- Keep a water bottle nearby.
- Take small sips whenever you feel comfortable.
- Drink fluids between meals if larger amounts with meals make you uncomfortable.
- Try cold water, lemon water, or lemon tea if they work well for you.
- Choose foods with a high water content, such as fruits and vegetables.

Second Trimester
As pregnancy progresses, your body continues to change.
After entering the second trimester, many women find that nausea starts to improve, which can make it easier to drink fluids regularly compared to the first few weeks of pregnancy.
Continue drinking water and other healthy fluids like coconut water or smoothies, especially when you feel thirsty. Try not to postpone drinking water (something many of us do when we are busy).
Staying hydrated is a simple habit that supports your changing body and your growing baby.

Third Trimester
This was the trimester when I personally felt much more thirsty. However, not feeling increased thirst does not always mean there is a problem, as pregnancy experiences can vary.
During the third trimester, your body continues supporting your growing baby, and your fluid needs may change as your pregnancy progresses.
Some women may experience:
- Increased thirst
- Heartburn
- Constipation
- Feeling full more quickly
- Increased urination
If drinking a large amount of water at once feels uncomfortable, try taking smaller amounts more frequently throughout the day.
What Are the Signs of Dehydration During Pregnancy?
Possible signs of dehydration during pregnancy may include:
- Dark yellow urine
- Constipation
- Dry mouth
- Headache
- Dizziness
- Feeling very thirsty
- Urinating less frequently
- Weakness
- Unusual tiredness
Urine color can be a general clue about your hydration level, but it is not the only way to understand whether you are drinking enough fluids.
If you are concerned that you may be dehydrated, feel unwell, or experience symptoms that worry you, contact your healthcare provider for advice.
What Should You Drink During Pregnancy?
Water is the simplest everyday choice for staying hydrated during pregnancy. However, you can also include other healthy drinks as part of your daily fluid intake.
Milk
Milk provides fluids along with important nutrients such as calcium and protein, which support your changing body during pregnancy.
I personally enjoyed drinking a glass of milk every night before going to sleep. If you enjoy milk and can tolerate it well, it can be a nutritious addition to your pregnancy diet.
Soups
Homemade soups can be a good option when you do not feel like eating a large meal. They provide fluids along with nutrients from vegetables, lentils, or other ingredients you add.
Smoothies
Smoothies can provide fluids along with fruits, vegetables, yogurt, and other nutritious ingredients. You can add options like oats, nuts, or seeds to make them more filling and nutrient-rich.
Coconut Water
I enjoyed drinking coconut water during my pregnancy, especially because my pregnancy was during summer. It can be a refreshing drink option for many women.
However, if you have any specific health conditions or concerns, it is always better to ask your healthcare provider before consuming large amounts. Also, check the label when buying packaged coconut water.
Ginger Tea
If you enjoy ginger tea, it can be a comforting drink option, especially during times when you are experiencing nausea. However, choose the amount that feels right for you and follow your healthcare provider’s advice if you have any concerns.
What Drinks Should You Avoid or Limit During Pregnancy?
While staying hydrated is important during pregnancy, some drinks should be limited or avoided to support your health and your baby’s development.
Excessive Caffeine
During pregnancy, it is generally recommended to limit caffeine intake. Caffeine can be found in:
- Coffee
- Energy drinks
- Some soft drinks
- Chocolate
- Other caffeinated beverages
The amount of caffeine that is appropriate during pregnancy may vary, so if you are unsure about your intake, discuss it with your healthcare provider.
Energy Drinks
Energy drinks often contain high amounts of caffeine and may also include other ingredients that may not be recommended during pregnancy. It is best to avoid energy drinks unless your healthcare provider advises otherwise.
Alcohol
Alcohol should be avoided during pregnancy because it can affect your baby’s development. If you have questions about alcohol exposure during pregnancy, speak with your healthcare provider for personalized advice.

Hydration During Morning Sickness
During my first trimester, I personally experienced a lot of difficulty and discomfort when it came to drinking water. Sensitivity to smells, nausea, and certain foods and drinks becoming difficult to tolerate made staying hydrated more challenging than I expected.
I found that taking small sips of chilled water worked better for me instead of trying to drink a large glass of water at once. If you are unable to drink enough fluids because of vomiting or morning sickness, you can also try water-rich foods and cold fluids that feel easier to tolerate.
Severe vomiting during pregnancy can lead to dehydration and may require medical attention. If you are unable to keep fluids down, contact your healthcare provider.
Can You Get Water From Foods?
Yes.
Some foods contain a good amount of water and can contribute to your overall fluid intake.
Water-rich foods include:
- Watermelon
- Oranges
- Strawberries
- Tomatoes
- Cucumbers
- Soups
- Yogurt
However, eating water-rich foods does not mean you should stop drinking fluids. A combination of regular fluid intake and a balanced diet can help support hydration during pregnancy.

Simple Tips to Drink More Water During Pregnancy
Keep a Water Bottle Nearby
Keeping water within reach can make it easier to remember to drink regularly.
One thing that helped me stay hydrated was using a time-marked water bottle. It reminded me to drink water throughout the day instead of realizing later that I had not consumed enough fluids.
Set Simple Reminders
It is easy to forget drinking water, especially when you are busy or dealing with pregnancy symptoms.
I used to set reminders on my mobile every one or two hours, which helped me remember to take regular sips throughout the day.
Add Natural Flavors
If plain water feels boring or difficult to drink, you can add natural flavors such as:
- Lemon
- Orange slices
- Cucumber
- Mint leaves
- Fresh fruits
This can make water more enjoyable and encourage you to drink more.
Drink With Meals or Between Meals
Some people prefer drinking water with meals, while others find it more comfortable to drink between meals.
During pregnancy, especially if you experience nausea or feel too full quickly, find a routine that works best for your body and lifestyle.
Hydration During Hot Weather and Exercise
If it is summer, the temperature is high, or you are doing physical activity, your body may need more fluids because you lose more water through sweating.
During these situations, pay attention to your body’s signals and make sure you drink enough fluids throughout the day. If you notice any signs that you may be dehydrated, try to drink water or other healthy fluids soon.
Staying aware of your fluid needs is especially important when you are outside or physically active in hot weather.
Hydration and Gestational Diabetes
If you have gestational diabetes, paying attention to your fluid intake becomes even more important.
I had gestational diabetes during both of my pregnancies. During my third trimester, I found that staying hydrated helped me maintain a healthier daily routine.
Water is usually the best everyday choice because it does not contain added sugar or extra calories. I also focused on balanced meals, regular eating patterns, and following my healthcare provider’s guidance to manage gestational diabetes.
Everyone’s needs are different, so if you have gestational diabetes or questions about your fluid intake, discuss them with your doctor or a registered dietitian.
When Should You Contact Your Healthcare Provider?
Contact your healthcare provider if you:
- Have severe diarrhea
- Notice signs of significant dehydration
- Are urinating much less than usual
- Are vomiting frequently
- Cannot keep fluids down
- Feel unusually weak or unwell
If you are worried that you are not getting enough fluids or something does not feel right, it is always best to speak with your doctor for advice based on your individual situation.
