Have you ever felt nauseous after taking the coffee?  I bet you have.

That is the reason you have searched in Google "Why does coffee make me nauseous?".

Well, there are a lot of reasons to feel nausea due to coffee.


In this article we’ll explain 5 reasons why coffee can make you nauseous and how can you prevent it

Here are 5 reasons  why coffee makes you Nauseous

You are probably dehydrated

If you are having coffee on an empty stomach that can be the reason you are feeling nauseous. It makes you thirsty and dehydrated. As a result, you may get headaches, dizziness, and other symptoms of dehydration.


So, don't rush to have a cup of coffee first thing in the morning.  

Instead, hydrate your cells and flush out toxins by drinking water first.

Drinking eight glasses of water a day is  recommended by health experts.

You can't replace bottled water with coffee.

Too much coffee Caffeine messes up your hormones

Moreover, caffeine increases antidiuretic hormone (ADH) secretion, so you'll need to drink even more water to compensate after you drink coffee. 


Some people experience nausea after drinking coffee because they are thirsty and haven't eaten anything beforehand, which triggers nausea.

 You consumed coffee on an empty stomach

As soon as you take that first sip of coffee, it wakes up your stomach, which then starts making acid that it doesn't need to.


Your stomach gets ready for a breakfast meal, but instead, you fill it with your favorite drink.


If there is nothing for the acid to break down, it can start to hurt the lining of your stomach. In the end, you end up with an ulcer, heartburn, or acid reflux.

This is especially possible with your first cup of coffee in the morning. Caffeine alone does not cause nausea, but drinking coffee on an empty stomach can delay digestion.

In doing so, you increase the likelihood of experiencing the consequences that come with having excess amounts of coffee rapidly.

You are sensitive to Caffeine

Caffeine may cause acid reflux if you have a sensitive stomach. In this situation, a less caffeinated beverage, such as cold brew, iced tea, or even water, is preferable to coffee.

Have a cup of coffee, but don't overdo it. Caffeine in coffee can interfere with sleep and give you a headache if you drink it after 2 in the afternoon

You can try going without coffee for a few days to see if it helps with nausea. If that's the case, you may choose to cut back on your caffeine intake instead of giving it up altogether.

You used too much cream or sugar

Sugar and nausea have a complicated relationship. 


But it has been demonstrated that sugar and cream in coffee might produce nausea since they are rapidly absorbed by your digestive system. 


Switch to black coffee or dark roast for a few days to help relieve nausea and make you feel better.

How to prevent getting nauseous from coffee?

Some coffee creamers and syrups are full of flavor and chemical makeup that tend to upset the stomach of coffee lovers.

But let's not jump to conclusions yet when you can find out by reading if it's your intense drink or the coffee's acids.

You can try following all of these steps to figure out what seems to be the reason for your upset stomach.

Avoid Artificial Sweeteners

Next time you reach for a zero-calorie sweetener, you might want to think again. Sweeteners with no calories are made in a lab, which means they may contain harmful chemicals causing nausea.

The bacteria in your gut can be upset by sweeteners, which can cause problems with how your body works.

Try drinking your coffee without any of the artificial stuff and see if it makes a difference in how you feel. 

Avoid Artificial Creamers

Nondairy, low-fat, and artificial creamers are no better than the artificial sweeteners with which they are paired.


These creamers frequently contain unhealthy components, such as high fructose corn syrup, hydrogenated oils, thickeners, and several other artificial and potentially unsafe substances.

If you like a smoother taste or if the acidity is killing you, choose milk or creamer that is made from natural ingredients.

Or you can use a moderate amount of creamer next time you drink coffee.

Stop drinking coffee on an Empty Stomach

You might have had your caffeine fix and felt nauseous afterwards, and you might have wondered why are you feeling sick right after you drink coffee.

In general, the stimulant in coffee can make you sleepless, give you headaches, or make you feel sick.

All of these problems can be easily fixed by eating something before you next time you are drinking coffee first thing in the morning.

This practice can have an adverse effect on your digestive system by producing more acid levels.

Just by having a protein breakfast you can avoid this stomach discomfort without cutting back on coffee intake.

Start drinking Decaf Coffee

People who become nauseous as a result of the caffeine in coffee may find that switching to decaf coffee is a more pleasant option in their coffee consumption routine.


There are a number of additional advantages to drinking decaf coffee. For instance, it can help to boost the amount of energy that you have.


Additionally, it does not contain the same amount of calories or sugar as normal coffee does.


You can also consider using green tea or non-dairy products.

Try dark roasted coffee

The darker roasts of beans have much less caffeine than the lighter roasted beans. Depending on how sensitive your body is, cutting back on caffeine may help stop nausea.


People with considerably larger kidneys might be able to drink more coffee without feeling sick. So dark roast coffee beans are the way to go for a perfect morning cup of joe.
