What is Nausea?

Nausea is a feeling of uneasiness or sickness, often accompanied by vomiting. Various factors are responsible for nausea, such as food poisoning, motion sickness, or pregnancy. Nausea can also be a side effect of certain medications or radiation therapy.

Interestingly enough, the purpose of nausea is to prevent you from repeating whatever caused you to feel nauseous in the first place. If you are feeling sick after drinking water, then nausea stops you from drinking more. Although the physiology behind this reasoning is yet to be clarified, there are four pathways in our bodies that are responsible for the sensation of nausea.

  1. Disturbing the vestibular system: The vestibular system is the apparatus of the inner ear which plays a role in balance. And its disturbances vestibular system that is causing motion sickness and dizziness.
  2. Stimulating the central nervous system: There are many reasons why stimulation of the central nervous system can cause nausea. Some of these reasons include getting sick, migraines, vertigo, and extreme emotional triggers like anxiety.
  3. Activating the chemoreceptor trigger zone: The chemoreceptor is a trigger zone in our brains outside the blood-brain barrier. The consistent exposure to substances like toxins and medications circulating through our blood makes the chemoreceptor easily triggered.
  4. Triggering the peripheral pathways: Within the gastrointestinal tract and other organs lie our peripheral pathways. Triggering the peripheral pathways could mean toxins in our intestines from a blockage of the bowels.

Causes of Vomiting After Drinking Water

Here are causes of vomiting after drinking water:

Bacteria

Bacteria from contaminated water may cause one possible explanation for your sudden trip to the bathroom toilet. Bacteria lives everywhere – yes, even in water – however, in this case, the bacteria are harmful to our bodies and cause us to get sick.

Bacteria in water is a common occurrence in water supplies within America, but it depends on where you are getting your water from. Here are three examples of ways you can drink contaminated water:

  • Vacation in a foreign location: I’m sure we’ve all been told at some point, “don’t drink the tap water when you go away! Only drink bottled water!” And to be honest, that does have truth to it. So often, when we go to a foreign country on vacation, our stomachs do not adapt to the bacteria that live in that water, so we get an upset stomach.
  • Camping trips: The great outdoors is home to lots of things, one being unsafe drinking water. As always, bringing your own bottled water or carrying a water-filtering system with you is best to avoid any unfortunate mishaps. There are many living (and dead) things in natural waterways, which causes unsafe bacteria to grow. Moreover, if water is too close to fecal matter, it can be contaminated with disease-spreading microorganisms.
  • Home or public water supplies: Sometimes, harmful bacteria contaminate water from our faucets or public sources. This is usually due to old or rusty pipes, which can introduce iron and lead into the water. It’s important to note that not all vomit-inducing bacteria will make you sick – some might give you an upset stomach.

Parasites

Although not as common, sometimes the culprit behind your vomit sessions may be due to parasites. Parasites are tiny organisms that live off of other creatures – including humans.

Ingesting contaminated water is one way you can contract a parasitic infection. These infections are more common in underdeveloped countries where water sanitation is not up to par.

A few examples of water-borne parasites include:

  • Cryptosporidium
  • Cyclospora cayetanensis
  • Giardia lamblia

Each of these parasites can cause various gastrointestinal issues like nausea, vomiting, diarrhea, and weight loss.

Often, these infections will go away on their own. However, it’s best to see a doctor if you experience severe symptoms or vomit for longer than two days.

Intense Exercise

Sometimes, nausea after drinking water can be due to over-exertion during intense exercise. When we push our bodies to the limit, sometimes our bodies can’t handle it, and we end up feeling sick.

Dehydration is one possible explanation for this vomit-inducing sensation; when we are severely dehydrated, our body temperature rises which causes us to feel nauseous and sometimes vomit.

It’s essential to listen to your body during a workout and take breaks when needed. Also, drink plenty of fluids – especially water – to stay hydrated.

Overhydration

Usually, we wouldn’t think overhydration causes nausea, but sometimes, it’s the case. We’re mainly concerned about dehydration, but overhydration can be just as dangerous.

Overhydration leads to water intoxication. This happens when our healthy salt and electrolytes become too diluted due to too many fluids. Overhydration can cause what’s called hyponatremia. Hyponatremia is a condition caused by an unhealthy low amount of sodium in the body.

A full stomach

Sometimes it’s that easy. A full stomach is all it takes is a full stomach to make you feel sick. This is typically the case after eating a heavy or rich meal. To avoid this, try to drink water before meals rather than forcing water into a full tummy.

In addition, sometimes our stomachs have a hard time emptying their contents. So, if you can, try to avoid drinking large amounts of water in one go. It’s important we give our stomachs the time they need to release fluids before we fill them back up.

Pesticides

Pesticides are commonly used in farms to protect crops from insects, weeds, and fungi. Although these chemicals are necessary for agriculture, they can also pose a risk to our health if we’re not careful.

Pesticides-contaminated water can cause several health issues like nausea and vomiting. Pesticide poisoning usually occurs after eating contaminated food or water. In severe cases, it can lead to organ damage and even death.

If you think you may have consumed contaminated water, it’s essential to see a doctor immediately.

Algae blooms

Algae blooms are water contamination caused by an overgrowth of algae in freshwater systems due to hot weather, rain, and chemical runoff. Chemical runoff? Yes, sometimes chemicals from sewage treatment plants and other facilities can leak toxic chemicals into our waterways. These chemicals encourage the growth of algae blooms which are unsafe to humans and can make people and animals sick. One good thing to mention, however, is that not all algae outbreaks are toxic to humans.

Symptoms of algae poisoning include:

  • Nausea
  • Sore throat
  • Vomiting
  • Diarrhea
  • Liver pain

Transition metals in water

Two transition metals that cause nausea, vomiting, and diarrhea are antimony and cadmium, and these metals will make us sick when their content in water is above the Environmental Protection Agency’s (EPA) water limits.

MTBE

Methyl Tertiary Butyl Ether (MTBE) is a gasoline additive used in an attempt to make gas burn clearer and to reduce the impact of carbon emissions in our atmosphere.

Unfortunately, MTBE is a toxic water hazard that is a known animal carcinogen and is possibly a carcinogen to humans as well. In the past, MTBE has contaminated the tap water of millions of Americans and made the water undrinkable.

MTBE is a volatile chemical that’s vapors absorbed by water readily and contaminates large quantities of water. It easily contaminates groundwater during its migration and has forced numerous public water providers to put a seal on drinking water well.

Nausea is one of the most common symptoms associated with MTBE exposure. Other symptoms include:

  • Dizziness
  • Headache
  • Loss of coordination
  • Shortness of breath

How to Get Rid of Nausea After Drinking Water

Here are some of the effective ways to get rid of nausea after drinking water.

Cut Back Your Water Intake.

If your issue is the result of overhydration, cutting back on fluids will help bring your sodium and electrolyte levels to a healthy amount.

Drink Small Amounts of Water

As previously mentioned, sometimes what causes us to feel nauseous and even vomit from drinking water is that we’re intaking too much, too fast.

To help get rid of that feeling, try to drink small amounts of water throughout the day rather than large amounts at once.

Replenish Your Salts and Electrolytes

Sometimes our bodies mistake dehydration for craving salt. Strange, right? If you’re finding yourself really thirsty, and drinking water doesn’t help, try eating something salty or having a drink with electrolytes and see if that does the trick.
