We need water to survive, but for some reason it makes us feel sick sometimes. What is up with that? Surely, the thing we need to survive shouldn’t make us feel unwell? 

But, the thing is, it’s unlikely it is the water that is making you sick. Most of the time, if you feel sick after drinking water, it is simply because you are too full, and you are just overloading your stomach

But, that might not be the only reason. So, let’s learn a little more together about the weird occurrence that makes you, me, and everyone else wonder what on earth is going on with our bodies.

Why Do I Always Feel Sick After Drinking Water?

The time when most people will feel sick is after they have eaten a meal. If this is the case for you, then it might be that your stomach is too full, and you’re just overloading it.

If you are dehydrated, you will naturally feel nauseated. When you are drinking water you hydrate your body, but if you are dehydrated, one glass probably won’t totally fix things, 

If you have been dehydrated for a while you will need to drink plenty of water, but drink it slowly as your body will need time to get back to normal. 

Vomiting After Drinking Water Or Eating

If you are vomiting after eating or drinking, it doesn’t really matter that it is water. The chances are that if ingesting anything at all makes you physically sick, you could have food poisoning or stomach infection. 

If this issue persists, it is best to see a doctor as you will start to lack the nutrients that your body needs to function.  

Food poisoning can be a big problem, depending on the type of poisoning, if you notice this issue occurs after eating something like chicken, get to a doctor as soon as you can.

Bloating And Nausea After Drinking Water

In this case, it would be ‘literal’ water weight. When you drink water it will go to your stomach, and if you drink a lot of it, it will make you feel and look more full. However, it is absorbed pretty quickly into your body, so it will usually be temporary bloating

However, if you are getting nausea and bloat at once, this is probably the case that you ate a large meal beforehand and then chugged down a load of water too, making you even more full, which will make you feel rather sick and look bloated.

Remember, your stomach can expand, but you should not push it to its limits.

Reasons Why You Feel Sick After Drinking Water 

The main reason why you would feel sick after drinking water would be because your stomach is too full or too empty. It is usually no other issue and is, therefore, nothing to worry about. 

You should only worry if you are persistently nauseated or are sick after eating food that may have caused food poisoning. You can also have a stomach virus, however, be aware that this nausea and vomiting will happen all the time if this is the case.

If it is a virus or food poisoning, nausea will happen constantly, not just when you are ingesting fluids.
