Why Drinking Water Causes Nausea: Causes and Remedies

Drinking water can provide many health benefits, so why does it sometimes make you feel nauseated? This may sound counterintuitive like it’s missing the point of drinking water. The opposite is true. Drinking too much water can have serious implications, and nausea is one of them. It’s especially a concern if you drink large amounts on an empty stomach or while exercising.

When getting rid of nausea after drinking too much water, the best thing to do is wait for your body to adjust its electrolyte balance naturally. This will help regulate how your body absorbs water going forward.

Additionally, sipping small amounts slowly throughout the day instead of drinking large volumes all at once can be easier on your system and help prevent any uncomfortable nausea in the future. Fortunately, these days there are many options to make staying hydrated convenient yet not overwhelming your digestive system – take advantage of them.

What Does Nausea Means?

Nausea is a feeling of unease in the stomach that can be accompanied by discomfort, queasiness, or an urge to vomit. Various things, including certain medications, motion sickness, pregnancy, and emotional stress, can cause nausea. In some cases, drinking water can also cause nausea.

When it comes to drinking water causing nausea, there are several possible explanations. It could be related to drinking large amounts of water too quickly or due to an imbalance in electrolytes caused by drinking too much water. It’s also possible that the nausea results from an underlying medical condition that causes discomfort when consuming water.

Why Would Drinking Water Cause Nausea?

Nausea is a very unpleasant feeling that most of us will experience at one time or another. It’s an upset stomach, with feelings of dizziness, weakness, fatigue, and possibly even vomiting. But why do we get nauseous? It’s actually a defense mechanism the body employs to get rid of any potentially hazardous substances it might have ingested or been exposed to.

Nausea is often a warning sign when something isn’t quite right in our bodies. If we’ve consumed something that is contaminated or poisonous, our bodies may produce nausea as an attempt to rid ourselves of the infection.

This system protects our bodies from potential harm by removing unwanted material before it can cause further damage. Emotional stress can also trigger nausea to help lighten the load and provide an escape from an uncomfortable situation. So while nausea is usually seen as an annoying symptom, it’s also extremely important in helping us protect ourselves from harm and keep us healthy.

Reasons to Get Nausea

The Stomach Is Full

The human stomach is a remarkable organ, capable of storing and digesting food with amazing efficiency. However, to ensure its optimal performance, it’s important to remember that it has limits. Specifically, the stomach can only hold so much food before it’s full—about one quart. Once the capacity is reached, any more food will lead to spillage, as it must be forced out of the body.

The stomach is too full can be avoided by paying attention to portion sizes and the frequency of meals throughout the day. Eating smaller meals more often can prevent a single meal from overfilling your stomach and spilling out where it doesn’t belong.

Additionally, taking time to savor each bite and chew thoroughly gives your body ample time to register when you’re full. Common signs include feeling bloated or even pained after eating too much. This said, if you do end up with a stomach that’s too full due to overeating, taking deep breaths and drinking lots of water until bloating subsides should help lessen discomfort until digestion runs its course.

The Stomach Is Empty

The stomach is a remarkably sensitive organ and can be easily thrown out of balance when empty. When the stomach is empty, acid builds up in the digestive system, leading to a sensation of nausea. This occurrence is usually referred to as acid reflux, and it can cause heartburn or indigestion. In addition to feeling nausea, people can experience pain or cramps in their stomachs trying to digest food that isn’t there.

Adding liquids like water, juice, or coffee might seem like a good idea to soothe an empty stomach, but this could actually make matters worse as these liquids mix with and dilute the already too-acidic environment.

Instead of offering anything for the stomach to absorb and digest, these liquids increase the number of fluids being digested by an empty body part. Combining an empty stomach and high liquid levels will only lead to more discomfort until something solid is consumed again.

Dehydration and Low Blood Sugar Levels

Dehydration occurs when the body loses more fluids than it takes in, leading to an imbalance of electrolytes. This can be caused by a lack of drinking water, excessive vomiting, sweating, or diarrhea. When the body enters a state of dehydration, nausea is more likely to be a warning sign of impending health problems. To avoid this, drinking enough fluids throughout the day is important.

Low blood sugar levels can also cause sensations of nausea. Blood sugar is the energy source for our bodies, and when we don’t have enough, it can throw off our equilibrium and lead to feelings of nausea.

Eating food with a good balance of carbohydrates, proteins, and fats will help keep blood sugar levels at an even keel. In addition, staying well-hydrated with water throughout the day will provide the body with a steady supply of energy to keep it functioning properly.

Lack of Electrolytes

Electrolyte imbalance is a common problem we can all encounter at any stage in life. It occurs when the body lacks essential minerals like potassium, sodium, and calcium, which are needed to keep our bodies functioning normally.

If you’ve been losing fluids due to extended physical activity, taking certain medications, having kidney or heart issues, or suffering from an upset stomach, your electrolytes may be imbalanced. Symptoms associated with this condition include fatigue, nausea, and water retention.

It’s important to prevent such imbalances by staying hydrated and incorporating electrolyte-filled liquids into your diet. Water alone is not enough; you should opt for sports drinks and other drinks containing these necessary minerals regularly.

Eating nutritious foods that contain potassium and sodium—such as bananas, potatoes, and legumes—is also beneficial for keeping electrolytes balanced. By making simple lifestyle changes like staying hydrated and eating healthy balanced meals, you can avoid problems related to electrolyte imbalance.

What to Do If I Get Nausea?

The belly’s all a-gurgle, and the tummy’s all a-rumble. But fear not, my friend. There’s a simple solution to this pesky problem: grub time. Get food in that belly, and the H2O will flow like a dream. No more bellyache, no more acid reflux, just pure liquid satisfaction. So what are you waiting for? Chow down and hydrate.

Nausea from drinking water is a surprisingly common issue. While it’s usually nothing to worry about, it can be uncomfortable and inconvenient. In most cases, the cause of this feeling is related to dehydration or an electrolyte imbalance in the body.

Drinking even small amounts of water can trigger nausea when your body is dehydrated and low on essential minerals like sodium and potassium. Just eat some food and water, and after a few moments, you will be fine.

Frequently Asked Questions [FAQs]

1. Why Do I Feel Dizzy After Drinking Water?

Feeling dizzy after drinking water can indicate an underlying health condition. Dehydration is one possible cause, as the body needs water to function properly, and dizziness can be a symptom of not getting enough fluids. Other causes include low blood sugar levels, which can occur if you don’t eat enough before or after drinking; electrolyte imbalances due to certain medications; or an underlying condition such as inner ear infections, vertigo, heart problems, or anemia.

2. What Relieves Nausea Fast?

Nausea is an uncomfortable feeling of needing to vomit and can be caused by various factors. One potential cause of nausea is drinking too much water too quickly. This can happen if you consume large amounts of water at once or drink more than your body needs.

3. What Happens If You Drink Water Too Fast?

Excessive water consumption rapidly, known as “water intoxication,” disrupts the balance of sodium and other electrolytes in your body. Consequently, water shifts from your bloodstream into your cells, causing them to expand. This can result in severe swelling, especially in the brain, and necessitates prompt medical attention.

4. How Much Water Is Too Much In One Hour?

Healthy kidneys typically excrete approximately one quart of fluid per hour. Consuming more fluids than this amount can result in water retention, leading to a medical condition called hyponatremia, which can harm one’s well-being.

5. What Is Wooziness?

The term “wooziness” encompasses a variety of symptoms, including mental confusion, weakness, lightheadedness, instability, and mild nausea.


Drinking water can cause nausea due to dehydration, electrolyte imbalances, low blood sugar levels, and underlying conditions such as inner ear infections or vertigo. If you experience nausea after drinking water, eating something with a good balance of carbohydrates, proteins, and fats and drinking fluids in moderation may help alleviate this feeling. In some cases, however, wooziness may indicate a more serious medical condition, and it is important to seek immediate medical attention if the symptoms do not resolve.
