Why Do You Feel Nauseous After Drinking Water?

Your mouth isn’t used to water when you swallow it because water is so essential and beneficial; it does not mean that we can drink water whenever we want to. When your body detects that something isn’t quite right, it responds in one of two ways: 

  1. It stimulates the gag receptors in your throat, triggering the gag reflex.
  2. It stimulates the vomit receptors in the back of your throat, which might cause vomiting. This is why drinking water makes you feel sick.
  3. A gag reflex and a vomit reflex are both present in you. You will feel sick if a water source activates one or both of these reactions.

What Causes Nausea After Drinking Water?

Water can make you nauseous in a variety of ways, including:

  1. Water Contamination

Your body interprets the water as tainted. Natural defensive mechanisms exist for a reason. Your body can protect you from hazardous diseases by not always being able to distinguish the difference between bacteria and other germs. When your body detects anything in the water that isn’t a bacteria or other germ, it becomes overprotective.

  1. Stomach Spasm

Your stomach is spasming. When you drink water, your stomach stretches to accommodate the water. But, doing so also triggers a reflex that causes your stomach to spasm. This is why you feel like you need to hurl, even if you’re not throwing up.

  1. Germs 

Even if you’re not a germaphobe, many have a threshold for germs. When we’re exposed to high germs, our bodies respond defensively to help protect us from getting sick. This is known as the immune response, and it’s a natural part of our physiology. The immune response can be triggered by water and certain microorganisms. 

  1. Hydration

Another reason why drinking water can make you nauseous is because the body uses it to maintain hydration, balance electrolytes, and eliminate waste products. When you drink water, it passes through your gastrointestinal tract and gets eliminated from your body. 

When you’re hydrated, and your cells receive the correct balance of electrolytes such as sodium and chloride, it will not make you nauseous. However, if you’re dehydrated and you don’t have enough electrolytes, drinking water can make you nauseous.  

  1. Halogens

Although drinking water is a fantastic way to stay healthy, it can make us feel ill. Some water sources include halogens, which are toxic to people. Water from natural springs contains these halogens. They are also present in some healthy water. You may suffer nausea after drinking water from those sources if you live where water supplies must be regularly regulated.

  1. Drinking water in the morning

It is a common belief that you need to drink water first thing in the morning when you wake up to be hydrated and to speed up your metabolism. If you’re drinking a lot of water in the morning, there is a possibility that you might be doing so on an empty stomach which may cause you pain because of low energy in your body. 

  1. Coldwater during exercise

Drinking cold water shortly after exercise might shock the digestive system because the body creates a lot of heat. Before any absorption can occur, the body must first warm itself in cold water. This shock can make you feel sick, queasy, or cause stomachaches.
