Nausea After Drinking Water: Why Do I Feel Sick?

Have you ever felt sick or tired after drinking water?

Ever wondered why it happens?

There are many possible explanations. If you’re interested in learning more, keep reading!


Although it isn’t painful, nausea can sometimes be very unpleasant and often comes with a strong urge to smoke.

To prevent you from repeating the same thing that caused your distress, nausea exists. It is not clear what the physiology of it is. There are four possible causes of nausea and vomiting in the body.

  • Stimulation of Central Nervous System (CNS). Elevated intracranial pressure, the meninges (i.e. blood or disease), and intense emotional triggers such as anxiety can cause stimulation of the CNS.
  • Chemoreceptor Trigger Zone Become Active —The chemoreceptor trigger area is located in the brain, away from the blood-brain border. It is easily exposed to drugs and toxins circulating through the bloodstream.
  • Triggering the Peripheral PathwaysThis could be caused by toxins in the gastrointestinal lumen. Distension of the intestinal lumen due to dysmotility, blockage of the stomach, or other factors could also be activators.
  • Vestibular System DisruptionsVibrations, sickness, or movements that cause disturbances to the inner ear’s vestibular system can lead to disruptions.

There are several reasons for nausea after drinking water

It is easy to diagnose fatigue by finding out why you feel dizzy or if you just feel like throwing up after drinking water. There are many possible causes. There is one thing that is certain: Drinking water shouldn’t cause nausea.

The following list outlines the possible reasons for your suspicion.

1. Drinking Water on a Full Stomach

It seems so simple, right? A full stomach can be the main reason you feel sick. You shouldn’t force water into your stomach, especially after a heavy meal.

Your stomach may have trouble emptying. Avoid drinking large quantities of water at once. Allow your stomach to empty fluid before you start drinking another cup. Consult a doctor if you have any other questions.

2. Bacteria Can Cause Nausea

The second possible yet improbable explanation is that you’re drinking bacteria-contaminated water. Yes, bacteria are very common even in U.S. water supplies. Is your water safe to drink because of potentially dangerous germs?

Water that is also near organic fecal matter can be infected by disease-causing microorganisms while outdoors. Even if you’re not on a camping trip you might be infected with waterborne pathogens at home or in public places.

Let’s look at giardia as an example of a parasite that lives in the small intestines. Giardiasis, which is caused by intestinal parasites, is the most common disease in our country. However, symptoms such as nausea and vomiting usually appear 1-3 weeks after the parasites are exposed, rather than immediately.

Cryptosporidium is one more parasite that may be the cause nausea and other symptoms such as abdominal cramping. The symptoms can last anywhere from a few days up to two weeks. It is a good sign if your nausea disappears after a few hours.

Both cryptosporidium, as well as giardia, can withstand water disinfection contamination.

Testing is the only way to determine if your situation is one of bacterial contamination. Either send a sample immediately to an accredited laboratory or purchase a test kit and conduct the research yourself.

Drinking water filter systems can be used to filter water if your water test is positive. Independent labs have certified it to meet NSF requirements.

3. Algae Blossom Outbreaks

Hot weather can cause toxic algae blooms in the lakes and rivers that supply our municipal water systems. The result? You may feel nauseous after drinking water.

Ingestion and skin contact have been shown to cause sore throats, nausea, vomiting, diarrhea, liver damage, and even death. It was found that algae outbreaks are on the rise at alarming rates. The number of reported outbreaks in 2010 was 3. There were 169 cases in 2017.

There is good news: not all algae outbreaks produce toxic substances.

4. Antimony & Cadmium

Cadmium and antimony are metalloids and transition metals. They can cause nausea, vomiting, diarrhea, and other symptoms in excess of the EPA drinking water limit.

The civil legal limit for antimony is 6 parts per billion (ppb), whereas the suggested health principle defined by the California Office of Environmental Health Hazard Assessment (OEHHA) is 1 ppb.

Cadmium is allowed at a maximum level of 5 ppb in drinking water. This limit is set by an enforceable federal standard. The current OEHHA guidelines for cadmium are 0.04 ppb, which is 125 times less.

Side note: According to the EWG Tap water heater, Garden Acres Mobile Home Park, Calabasas (OK) had the highest average concentration of water cadmium in 2015 at 13.7 ppb. This is more than twice the legal limit. With 8.49 ppb, the Crown King Water Company in Glendale, AZ was awarded the second rank.

Antimony samples from 2015 were taken in the Quail valley Water in Tehachapi (CA) and had an average of 11.3ppb. This was enough to secure the first place. Hanson Water Department, Hanson, MA was next with 9.00ppb. Congratulations!

5. Be Aware of Pesticides

Low doses of chlorpyrifos, a commonly used pesticide, can cause nausea, headaches, and nausea. It is clear that it comes from agriculture, which is one of the main contributors to the contamination in our drinking water.

The U.S. 9th Circuit Court of Appeals ordered in August 2018 that the EPA ban chlorpyrifos within 60 days.

6. Water Contaminated by MTBE

Between 2010 and 2015, MTBE was served as a toxic byproduct from oil refinement to millions of Americans in the form of polluted water. The water is contaminated by MTBE, a foul-smelling chemical that makes it unsuitable for drinking. The good news is that the guidelines for health were not exceeded.

It is shocking that there is currently no federal drinking water standard.

Another problem is that MTBE can easily migrate through groundwater. This has caused widespread contamination of groundwater in the United States, causing many public water providers to close their drinking water wells.

MTBE has been linked to Nausea and dizziness, headaches, and disorientation. It is quickly absorbed by the intestines.

7. Contaminated Water

Your water could be polluted. This could be a serious underlying problem that can make you sick if you are drinking water from your tap or another source. If you suspect that your water supply may be contaminated or contain organic fecal waste, you should have it tested.  Talk to others who have been drinking the same water as you to see if it is happening to them. If so, it could be that there is contamination or germs in the water supply which makes people sick. This must be addressed immediately.

8. Food

It is possible that you are feeling nauseated by food, not water. It may seem obvious, but it is important to pay attention to what you eat if you feel sick. If you drink water and feel sick, but have just eaten a huge greasy or cheesy dinner, chances are that it is the food, not the water. It can help to keep a food diary in order to identify patterns and find out if something is causing your dizziness or stomach upset.

9. Feeling Sick from Water Poisoning

You can be sure it’s water if you look at how much water you drink each day. This could indicate severe water intoxication. It is possible to drink too much water per day. Water intoxication can cause death and is a serious condition. Even if it doesn’t cause death, you’ll get very sick and need to stay in the hospital for treatment. It’s a good idea to have eight glasses of water daily, but don’t exceed this if you sweat a lot or are pregnant. Even if your situation is not covered by the eight-glass rule, it’s important to ensure you don’t drink too much water to increase your risk of developing this condition.

Drinking water can make you feel sicker than drinking it. You will feel dizzy and nauseous if you drink a lot of water. The discomfort should go away once the water has been absorbed and processed by your body. This can be reduced by taking small sips of water and nursing your water, rather than drinking it all at once. It is safer to sip water slowly than to drink large amounts of it quickly, even though it may be tempting.

10. You May Feel Nauseous After Drinking Water Fast

You might get sick if you are dehydrated and drink lots of water very quickly. For example, if you exercise hard but don’t have enough water during the workout, you might become dehydrated. Although you may feel compelled to rush home and drink a large bottle of water immediately, this will only make your symptoms worse. Continue to hydrate until you feel hydrated again. You should try to get some of your hydration through food, rather than drinking water. Pure water is also available from -fruits.

11. Feeling Sick Due to Other Digestive Issues

This can be caused by stomach or digestive problems. You might feel dizzy or nauseous if you have digestive conditions such as Crohn’s disease, IBS, or Crohn’s disease. Even if your condition is simple like heartburn or GERD there are other possible causes. It is likely that you have been diagnosed with something similar. If you are not yet diagnosed with something like this, it is a good idea to speak to your doctor to learn more about the requirements and determine if one could be a possibility.

It Doesn’t Have to Be Serious (But It May Be)

Your stomach may be too full, which can cause you to feel dizzy after consuming plain water. This is not something you should be concerned about. Give your stomach time to empty out before you take another sip.

If this doesn’t work, you should consult a doctor. To rule out contamination, you might want to have your water tested for any impurities like chemicals or germs. You can either filter your drinking water or buy bottled water if your water test is positive.

You Can Feel Nauseous After Drinking Water on an Empty Stomach

Nausea refers to the unpleasant sensation of having to vomit. This happens when the brain’s vomiting center is activated. You may say, “drinking water makes me nauseous during pregnancy.” Morning sickness can be caused by many things. There are many reasons why people feel nausea after drinking water in the morning.

This feeling is not uncommon. It may just be temporary. It could also indicate a serious health condition that requires immediate medical attention.

Water taken with an empty stomach can cause nausea and a burning sensation. It could be that your body lacks energy or you are hungry.

Lack of Energy Can Cause Nausea

Dehydration can make it difficult to drink water quickly if you’re not feeling well. No matter how hungry you feel, it is best to drink water slowly. Over time, you will be able to rehydrate.

According to Mayo Clinic, drinking too much water can lead to dizziness, fatigue, and loss of energy. This could be due to electrolyte imbalance in the body.

You should also try to get some nutrition from food, rather than drinking all of it. As a natural source of water, fruits are also a great option for rehydrating.

How to Get Rid of Nausea

It may not be easy to determine why you feel nauseated. It doesn’t matter why you feel sick. You can make it better.

These are some things you can do after drinking water to make nausea disappear:

  • Avoid clenching your stomach after drinking plain water. The gastric juices in your stomach could rise and cause nausea. Try moving as much as you can.
  • Get some fresh air. Fresh air can help with nausea symptoms. If you feel like vomiting, try sitting down under a fan.
  • Use a Cool Compressor to increase your body temperature. For a few minutes, you can reduce nausea by placing a cold towel on your neck.
  • Apply Pressure- The pressure point to relieve nausea is located on the inner wrist. To ease nausea, hold this pressure point for a few minutes.
  • Deep breathing can help ease nausea. Breathe slowly through your nose. Hold your breath for a few seconds, then exhale. Continue this until you feel less nauseated.
  • You can distract yourself by reading a book or watching television.
  • Lemons are good for digestion. Warm lemon juice can be used to stimulate bowel movements.
  • Ginger is antiemetic. It can also prevent nausea and vomiting. Take a small amount of ginger or make ginger tea to feel less nauseous after drinking water.


There are many reasons why you might be nauseous after drinking water. This is a common symptom and can be avoided.

Nausea can lead to diluted stomach acid and can even cause gastroesophageal reflux disease.

Many people wonder, “Why do I feel poisoned drinking water?” It can be caused by algae outbreaks hot weather, sewage treatment plants or even drinking plain water on an empty stomach.

It is important to understand why it happens so that you can prevent it from happening again.

Drink cold water slowly to avoid feeling sick.

If you avoid nausea you won’t have to worry about acid reflux and EPA drinking water limits.
