Why Does Drinking Water Make Me Nauseous?

Water is essential to survival, so if you’re experiencing nausea after drinking your tap water, it’s definitely not ideal. People who are nauseous after drinking water are less likely to want to drink water. Your drinking water is not likely the source of your nausea.

If you don’t feel well after sipping from a glass of water, you can find plenty of reasons why this might be the case. There are many reasons why you might feel nauseous after drinking, including caffeine or alcohol withdrawal. But there are ways to reduce your feelings of nausea.

In case you notice your softened water tastes salty, here’s why.

Nausea Overview

Nausea can come about for all manner of reasons. You could feel sick when you’re traveling, you could have acid reflux, or it could be food poisoning. Nausea and anxiety are both linked to the body’s stress response. It’s common to feel nauseous after a particularly tough workout, when you’re pregnant, or on a very hot day.

Some days it can happen without any reason. But if it happens a lot more often than that, it could be something else. Nausea is commonly associated with viral and bacterial infections, and so can occur due to an imbalance of bacteria in the stomach.

In this case, it’s usually accompanied by other symptoms, like the urge to vomit. Vomiting and nausea can also be signs of other issues, like a digestive problem or appendicitis. It’s not uncommon for someone to feel nauseous for no apparent reason. That being said, nausea can be a symptom of a wide range of health conditions, from the common cold to cancer.

This could mean that you’re having trouble determining why you’re feeling sick. There are some reasons for nausea after drinking water. However, it’s helpful to know what the potential issues are.

Does Feeling Nauseous After Drinking Water Always Indicate a Problem?

Nausea is often an indicator that something is amiss. However, it’s good to be aware that not every case of nausea after drinking means that something is wrong. You should see your doctor if you’re experiencing new, recurring, or lingering symptoms that are interfering with your life and your ability to work.

A doctor can run tests to diagnose a health issue, or simply reassure you that you’re healthy and offer suggestions for a solution to the problem.

What Causes Nausea After Drinking Water?

Stomach is Full

Stretching your stomach as far as possible is a great way to get rid of food, but a good rule of thumb is to only drink liquids when you’re almost done eating. When you eat a particularly large meal it’s best not to drink a lot of water straight away – wait at least half an hour before drinking any.

It is important to be in tune with your body here. If you’re eating slowly, you might want to eat a small meal every 2 hours instead of one big one.

Empty Stomach

There is a reason why many people experience feeling sick after drinking water on an empty stomach – your body is really hungry for food. Water is not the perfect source of energy, but it does offer a lot of benefits, such as improving brain function, helping to fight fatigue, and boosting mood.

Feeling nauseous after having a glass of water on an empty stomach indicates that you need to eat something. If you’re eating a good meal, your brain will actually signal your body to stop feeling hungry.


When you don’t drink enough water, it’s like having no food in your system. Many people who are dehydrated feel tired and weak, have headaches and feel nauseous. Dehydration causes these symptoms.

A simple way to tell whether you’re dehydrated is to look at the color of your pee. If it’s dark yellow and strong-smelling, you should drink more. Your body needs the right kind of fuel to live. Water is the only thing that provides your body with the energy it needs to survive.

Pregnancy (morning sickness)

After the first month of pregnancy, many women begin to experience morning sickness or nausea after they drink water. The name is a bit of a misnomer – you can actually feel like you’re going to throw up at any time, from the very beginning of the pregnancy to just

There are many signs that you’re pregnant, including frequent urination, spotting, nausea, fatigue, and low blood pressure. If you’re having trouble getting pregnant, it might be time to take a pregnancy test.

Lack of Electrolytes

Electrolytes are a common problem for many people, including us, the makers of the Power Bar! Here are some ways you can identify when you have electrolyte imbalance and tips on how to address it.

We need electrolytes – a group of essential minerals – to survive. Electrolytes can become unbalanced if you’ve lost fluids from heavy exercise, you’re taking certain medications (like diuretics and antibiotics), you have kidney disease, or you’ve had diarrhea or illness.

When your body isn’t getting enough calcium, the first thing you’ll experience is a feeling of lethargy, followed by fluid retention and then nausea. You can prevent electrolyte imbalance by staying hydrated, and drinking sports drinks that contain electrolytes.

Medical Conditions

When you have a digestive disorder or GERD that makes you throw up water after drinking water, you may experience nausea and throwing up water. People often think that drinking alcohol is a cause of heartburn. However, it’s not the case.

However, water should be your first choice when suffering from heartburn and indigestion. If you experience any of these symptoms, see your doctor. However, if the problem persists, drinking plain water should relieve the symptoms.

Water Contaminants

You may have a bacterial infection in your gut that’s making you feel sick. Municipal water from your tap can contain trace contaminants, and even well water is more likely to become contaminated. Some of the most common water contaminants include:


In many situations, bacteria is most commonly found in water wells that are used for drinking purposes. If this contaminant is found in your drinking water, it’s important to stop using tap water until it has been determined whether the problem is fixed

Heavy Metals

Metals are common in the majority of tap water sources. Heavy metals like copper and manganese are needed in our diets. Lead is one of the most poisonous heavy metals in drinking water and should be avoided at all costs.

Most people don’t get sick when they drink tap water. You may even enjoy the taste of it! These symptoms may be accompanied by the sensation that your stomach is churning, headaches, abdominal pains, the urge to vomit, diarrhea, fatigue, and difficulty breathing


Algae is a contaminant that can be found in both wells and municipal water sources, and it’s often present alongside bacteria. Blue-green algae are a danger in drinking water, and they’re best to avoid. Water treatment plants are not required to remove perchlorate from water before it’s treated or delivered to consumers.

As well as nausea, blue-green algae may cause liver and stomach issues, skin and eye irritation, and even respiratory problems. Blue-green algae can also cause severe illness or even death in pets, so if you suspect your pet is having an illness, contact your vet to find out


Pesticides can be found in both surface water and groundwater. The concentration of pesticides in your water depends on a number of factors, including your water source and the level of irresponsible farming activity in your local area.

Pesticides are heavily regulated by the U.S. Environmental Protection Agency, but some do exist in trace amounts, so it’s important to have ways of getting rid of them before they go off. Some of the acute health effects of pesticides are dizziness, rashes, blisters, diarrhea, and sometimes death.


Methyl tertiary butyl ether is the name for a group of chemicals that can contaminate our drinking water when there are accidents at oil refineries. Millions of Americans are drinking dangerous chemicals from their tap water, but they weren’t aware of the contamination. Thankfully, the levels of the toxic chemicals weren’t high enough to be hazardous.

If you still drink MTBE after knowing that it is related to nausea, you should arrange for a laboratory test. You should do this even if you don’t think your water is contaminated. Exposure to Methyl tertiary-Butyl Ether (MTBE) can cause headaches, dizziness and disorientation.

How Do I Stop Feeling Sick After Drinking Water?

If you feel sick or feel that you may throw up, then drinking lots of water may not make you feel any better. There’s a reason that you should drink more water throughout the day – it helps your body to regulate its temperature. If you can’t stand plain water from your tap, check out one of the solutions below.

Try Purified or Distilled Water

If you’ve put your post-drinking nausea down to the quality of your tap water, try drinking water that has been purified or distilled. You can buy bottled water that has been treated this way, or you can use a reverse osmosis filter or distiller to purify your own water.

Drinking water that contains no impurities might help you stop feeling nauseous. Home filtering is becoming more and more popular, with people using an at-home filter to clean and maintain their home. In both cases, the second sentence is grammatically correct, but is not the best fit for the given context.

Eat First, Then Drink

This may be confusing for your body because it assumes that the water is food, but if you feel that you don’t have enough energy or that your stomach is feeling bloated, then it could be the cause of your nausea.

Avoid drinking water on an empty stomach altogether and instead, drink a glass of water after every meal or snack. This can help to reduce your nausea, as your body will need more energy to work properly before you drink anything. If you drink too much, or if you eat too much, you’ll probably feel sick, so avoid it. Avoid drinking too much water at once, either.

Test Different Temperatures

Hot or cold water temperatures may be more difficult to stomach than others. Water is important to your body, especially during a workout, as it helps to replace your fluids and keeps your organs and muscles hydrated. Water can also help to ease your stomach and other symptoms of your first trimester nausea.

However, if you are hot and dehydrated, cold water may be far more palatable than warm or room temperature water. You’ll need to adjust the temperature of your water to determine whether being too hot or too cold is a contributing factor to your nausea.

Try Infused or Flavored Water

A good option would be to add a flavored or infused water in place of plain water, but you could also do this at home. There are plenty of healthy infusions to consider. Try adding mint, lemon slices, ginger root, basil, watermelon, orange, or rosemary to a big pitcher and letting the flavors mingle before drinking.

If you drink plain water that tastes awful, you might want to think about flavoring your water to improve the taste. A cup of juice can work if you’re sick. It’s a good thing to do to hydrate and reenergize your body. Drinking soda or juice won’t make you feel sick or have diarrhea, but drinking a lot of it all at once could cause that.

Take Smaller Sips, More Frequently

When drinking too much water on an empty stomach, it’s a bad idea because it makes you bloated and you don’t absorb nutrients properly. Overwhelm your body by drinking a lot of water and it will work too hard to process all that water. Take your time to do this.

Space out your water consumption by drinking small amounts throughout the day. If you feel nauseous just because you are drinking a lot of water at once, the problem will resolve itself within a few minutes.

Add Electrolytes or Salt

It’s very important to avoid nausea that results from low blood sodium. When your H2O intake is low, potassium, calcium and sodium can make a big difference in your body, especially if you perform high-intensity workouts.

Drink Water With Carbonation

If you’re suffering from nausea that occurs after eating, drinking carbonated water can help to relieve the discomfort. When you drink a glass of water with carbonation, your stomach’s total acidity should reduce, which may help to reduce your nausea within minutes.

I strongly recommend that you drink carbonated water over other types of drinks, such as fizzy drinks or sodas, because they typically have higher sugar and/or preservative concentrations.

Talk to Your Doctor

If you’re thinking, “water makes me nauseous, but I’m certain it isn’t. The best remedy for an upset stomach is to avoid alcohol. There are so many possible causes that it’s hard to say for certain.

Many women deal with imbalances of their body or a side effect of a hormonal change. Being examined by a medical professional will help you to solve the problem or simply make you feel more secure.

Your doctor will assess your health records and evaluate your symptoms before figuring out the cause of the problem. There are also health care professionals that will arrange for tests and additional diagnoses, if needed.

Frequently Asked Questions

Is there such a thing as drinking too much water per day?

Yes. Drinking more than 24-32 liters of water per day might result in a condition called hyponatremia. This happens when your kidneys are unable to filter out the extra water in your body.

If you’re serious about losing weight, you should really try drinking less. Most experts recommend that you only drink 2 liters of water per day. Don’t drink more than 3–4 liters of water within a short space of time. It may overwhelm your kidneys. Drink when you’re thirsty, or space out your drinking habits during the day or only drink when you’re thirsty.

Why can’t I drink water when I wake up?

You might not want to drink water straight away in the morning. It is recommended that we drink a glass of water immediately after getting up, but if your stomach isn’t feeling well, it may make you feel nauseous.

Drinking water on an empty stomach is the first thing to do if you’re thirsty. Add a lemon slice to your drink to help soothe your stomach.
