Why Does Coffee Make Me Nauseous?

Coffee is a beverage that people drink all over the world, and it’s so popular because of its energizing and delicious taste. However, some people feel like vomiting after drinking coffee and start asking, “why does coffee make me nauseous?” If you are facing the same issue, read on to find out all the causes!

Can Coffee Make You Sick?

Yes, coffee can make you nauseous. The main reason is that coffee is a diuretic, which means that it makes you urinate more. When you drink coffee, your body gets rid of more water than usual, and this can lead to dehydration. Dehydration is one of the main causes of nausea, and that’s why you may feel sick after drinking coffee.

In addition, coffee can also irritate your stomach and provoke an upset stomach. The acids in coffee can increase the production of gastric acid in your stomach, and this can lead to indigestion, heartburn, and even nausea.

Finally, it’s also important to note that some people are simply more sensitive to coffee than others. If you have a sensitive stomach, you may be more likely to feel nauseous after drinking coffee.

Why Does Coffee Make Me Nauseous?

Coffee is a beverage that contains an array of ingredients, including N-alkanoyl-5-hydroxytryptamine, chlorogenic acids, and caffeine. The presence of these substances can cause stomach irritation in some people if consumed too much or for prolonged periods at one time!

Coffee is a great way to start your day, but if you drink it too much, then the acids in coffee can cause some serious digestive problems. Acid reflux and stomach ulcers are just two effects that come from drinking too many cups of caffeine-filled Joe per day!

There are some common reasons why you are feeling nauseous after drinking coffee:

1. Drinking Coffee On An Empty Stomach

No matter how good it tastes, coffee can be a little too much for people when consumed on an empty stomach.

It’s not surprising that coffee is the most widely consumed drink in America. It has a lot going for it: strong flavors and aromas, and high levels of caffeine. These might be too much for your stomach to deal with without anything else to loosen its burden.

Therefore, skipping your breakfast and consuming only a cup of Joe is indeed a very bad idea!

2. Your Stomach’s Gastric Acid Just Can’t Cope Coffee’s Acids

Researchers have recently discovered the link between coffee and acid reflux, which may cause symptoms such as nausea or belching to occur when you consume it for long periods of time.

3. Because You Are Pregnant

Caffeine may increase the amount of urine you produce. It also increases your heart rate and blood pressure, which can lead to jitteriness or indigestion in some people if consumed regularly over time. 

This means that when consuming coffee or tea at any point during pregnancy, there is an increased risk of miscarriage and/or complications. These can be dehydration from excessive vomiting due to its negatively affecting effects on blood flow in organs.

4. Because You’re Dehydrated!

Coffee is a great way to get your caffeine fix, but it could also make you feel nauseated and drained. The high amounts of coffee in the diet may lead people to dehydration issues like vomiting or feeling thirsty more often than not.

If you’re feeling sluggish in the morning, it’s best to drink one cup of water before coffee. This will help to flush out hydrate cells and toxins while also giving yourself an energy boost! It is advised that you consume eight glasses per day as well, if possible!

Nevertheless, it’s always good to have a snack before drinking coffee! One cup of caffeinated beverage might be keeping your eyes open longer, but make sure it’s balanced with plenty of water intake per day!

5. Coffee Stimulates The Digestive System

The caffeine in coffee stimulates your stomach and intestines to move food along with more quickly. This can cause cramping or other side effects like pain, nausea, etc., but it’s typically only an issue if you drink too much before actually going to the toilet!

6. Excessive Caffeine Promotes Acid Production

Coffee may be the ultimate convenient food, but consuming over 4 coffee cups per day can make you feel nauseous due to excess in your body system. Based on many studies, 400 mg of caffeine (4 servings) per day is considered safe.

Caffeine’s most famous side-effect is an increase in the stomach’s acidity. That means it can make you feel like vomit and want to drink plenty of fluids! 

7. Because Of Milk & Sweeteners

If you’re still having trouble understanding why your stomach may be upset after drinking coffee, you might want to look up how you consume it! Did you add sweetener and milk to your cup? If so, that is the cause of the problem! Sweetener and milk in coffee can cause irritation to your body, especially your stomach, which leads to the feeling of nausea after drinking it!

Artificial sweeteners can change the balance of bacteria in your gut, which will cause distress to the acid-filled stomach you already have! Artificial creamers are almost as bad for you and your health as the sweeteners they’re paired with. They often contain harmful ingredients like hydrogenated oils, high-fructose corn syrup, thickeners, or other unnatural substances that won’t make you any healthier!

What To Do If You Are Feeling Sick After Drinking Coffee?

There can be many reasons for feeling nauseous after drinking coffee. It could be because of the caffeine, or it could be due to an underlying health condition.

If you are feeling sick after drinking coffee, it is best to consult a doctor to find out the exact cause. However, there are a few things that you can do at home to ease nausea:

– Drink lots of fluids: This will help to flush out the caffeine from your system and also prevent dehydration, which can make the symptoms worse.

– Eat small meals: Eating large meals can increase the feeling of nausea. It is best to eat smaller meals more frequently throughout the day.

– Avoid spicy and fatty foods: These can make the feeling of nausea worse.

– Try ginger: Ginger is a natural remedy for nausea. You can either drink ginger tea or chew on some ginger slices.

If you are regularly feeling nauseous after drinking coffee, it is best to cut down on your intake or switch to decaffeinated coffee. You should also consult a doctor to rule out any underlying health condition.

How Can You Drink Coffee Without Feeling Sick? 

Here are some useful tips for you to avoid feeling sick while consuming your cup of Joe!

1. Drink Coffee With Meals

So, coffee indeed is a great beverage for many people. It has an excellent flavor and can be enjoyed in so many ways – but it also causes problems for some drinkers! The high acidity of this drink makes you sick if consumed too often or on an empty stomach, as your body isn’t used to processing these strong acids.

Thus, eating whilst sipping some coffee should help reduce any negative feelings towards caffeinated beverages, as it helps neutralize excess bodily fluids during the digestion process.

The best way to avoid caffeine-induced nausea is with food. “The next time you drink coffee, eat before you drink or while drinking it,” says Dr. Gariglio-Clelland. 

She suggests that scrambled eggs work well because they are rich in protein and will help settle your stomach if there’s any upset from eating too little beforehand, but just about anything else should all work it out!

2. Give Cold Brewing A Go

In fact, cold-brewed coffee is trending, and it’s much better for your stomach than traditional methods. Coldwater does not extract as much, so you get a different end result in taste! According to some experts, cold brew contains up to 67% less acidity due to not being heated during production, which allows for an even extraction rate like the traditional one.

Moreover, cold brewing is a great way to have a cup of Joe with none of the bitterness or acidity you get from traditional methods. It also gives more aromatic and smoother flavors than hot brewing which many people enjoy!

3. Avoid Artificial Sweeteners and Creamers

Artificial sweeteners may be making you sick. They can cause an upset stomach and react negatively with your gut bacteria, which will make things worse for any digestive issues that already exist in coffee drinkers, like nausea or headaches. If these symptoms start after drinking a cup of joe made with artificial ingredients, then consider giving them up to see if the problem goes away!

There are many reasons why creamers might be a problem for you. One of that is that they’re usually loaded with vegetable oils and sugar, which do not bring any good to your digestion due to their reactions when in contact with your digestive system. Instead, opt for milk or real cream as an alternative as long as you do not have milk allergies.

4. No More than 4 Cups

Drink responsibly to avoid the negative effects of caffeine1

People who drink too much coffee can experience insomnia, anxiety, panic attacks, and irritability just by drinking four cups per day – that’s about 12 ounces or half a small pot! 

It’s best if you cut back on your intake even more for these unfortunate side effects, which will only get worse as time goes on. The experts recommend only consuming about 4 coffee cups per day. Or else, try to drink as much water as you can or consume coffee while eating! 

5. Stay Hydrated

By staying hydrated with water, your coffee will taste better too! The NHS indicates that “a small amount” of coffee won’t dehydrate our body, but it can still worsen the dehydration symptoms. So, we suggest you have two glasses of water before sipping the coffee!

Now, you’ve got the answer to the question, “Why does coffee make me nauseous?

Your stomach is a sensitive organ that can’t handle the acidity in coffee or any other acidic food that matters. Besides, drinking it on an empty stomach means you’re probably not getting enough fluids to dilute it, and your stomach acids just can’t cope with all of those strong acids. 

If you are pregnant, caffeine will also stimulate your digestive system even more than usual because hormones slow down digestion during pregnancy. Whether due to milk sugars or sweeteners, excessive amounts of caffeine promote acid production, which could make nausea worse!
