From exploring potential causes to providing helpful tips on reducing symptoms related to caffeine intake, keep reading if you want more information on what might be causing your adverse response to those seemingly innocent beans.

Overview Of The Effects Of Caffeine On The Body

Get the lowdown on how caffeine affects your body. When you consume caffeine, it gets in your system fast and you’ll start feeling its impact within half an hour. Get ready for a boost in your breathing and heart rate, plus a major jolt of mental alertness and physical energy. These effects can stick around for up to 12 hours, depending on the person. But be warned. Too much caffeine can mess with your body. Watch out for signs like a rise in body temperature, peeing a lot, getting dehydrated, feeling dizzy or getting headaches, a racing heartbeat, restlessness, anxiety, shaky hands, trouble sleeping, and a strange mix of energy followed by extreme tiredness.

Why Does Coffee Make Me Nauseous?

Why Does Coffee Make Me Nauseous?

Coffee can make you feel nauseous because it’s acidic and can irritate your stomach, causing it to produce more acid. It can also lead to dehydration, which can also make you feel nauseous. The caffeine in coffee is a stimulant and can also contribute to nausea. However, if you drink enough water to offset the caffeine, just half a cup of coffee shouldn’t make you sick. If you have a sensitive stomach or are sensitive to coffee, consider trying cold brew coffee as it’s less likely to cause nausea.


Coffee is acidic, which can irritate your stomach and cause it to produce more acid. This acid can then move up into your esophagus, causing heartburn or indigestion. If you have a sensitive stomach or issues with acid reflux, drinking coffee may trigger these symptoms and make you feel nauseous.

Caffeine Sensitivity

Some people have a higher sensitivity to caffeine than others, which can cause adverse reactions like nausea. This may be due to genetics or other factors such as overall health and medication usage. If you know that you are sensitive to caffeine, it’s important to limit your intake and try different forms of coffee such as decaf or cold brew.

Laxative Effects

Coffee is a known natural laxative and can cause digestive issues that may lead to nausea. This is because coffee stimulates the production of gastrin, a hormone that increases colon contractions and speeds up the digestion process. If you are not used to consuming caffeine regularly, your body may react more strongly to its laxative effects, causing discomfort and nausea.


Coffee can also contribute to dehydration, which can cause nausea. Caffeine is a diuretic, meaning it causes your body to produce more urine. This process can lead to dehydration if you are not drinking enough water to offset the effects of caffeine. It’s essential to stay hydrated when consuming coffee or other caffeinated beverages.

Additives And Ingredients

In addition to caffeine, coffee can contain other additives and ingredients that may contribute to nausea. For example, some people may have an adverse reaction to dairy milk or creamer added to their coffee. Others may be sensitive to artificial sweeteners or flavors used in flavored coffees. It’s essential to pay attention to what you are adding to your coffee and how it affects your body.

Empty Stomach Woes

Drinking coffee on an empty stomach can also make you feel nauseous. When consumed first thing in the morning, coffee can cause discomfort and nausea due to its acidic nature and potential laxative effects. It’s best to have a light meal or snack before drinking coffee to avoid this issue.

Histamine Intolerance

Another potential reason why coffee may make you feel nauseous is if you have a histamine intolerance. Histamines are chemicals that your body produces in response to an allergen or irritant. If you have a deficiency in the enzyme needed to break down histamines, consuming histamine-rich foods like coffee can cause symptoms such as nausea, headaches, and skin irritation. It’s essential to talk to your doctor if you suspect you have a histamine intolerance.


If you’re pregnant, coffee may make you feel nauseous due to the changes in your body. Your body is more sensitive and easily affected by stimuli, leading to a heightened response to caffeine. Additionally, hormonal changes during pregnancy can also contribute to nausea. It’s best to limit or avoid caffeine consumption while pregnant and consult with your doctor for personalized recommendations.

Drinking Too Much Coffee

Of course, drinking too much coffee can also make you feel nauseous. As mentioned before, caffeine is a stimulant that can have adverse effects on your body if consumed in excess. It’s essential to monitor your caffeine intake and limit it to moderate levels (400 mg or less per day) to avoid feeling sick.

6 thoughts on “Why Does Coffee Make Me Nauseous? | Causes & Solutions”

  1. I love coffee but recently it’s been making me nauseous. Anyone experience this?

  2. Similar symptoms here too. Just started a few months ago for me. In addition to a need to vomit is queasiness, runny nose, and light-headedness which intensifies when I’m in a moving vehicle. I’ve limited coffee to about 200ml/day for the past week, and the symptoms are gone.

  3. For everyone who says yes, try to drink a pint of water in the morning. Or whenever your stomach gets upset from coffee, just pound water. I’ve never had an issue drinking coffee on an empty stomach following this.

  4. Drinking coffee on an empty stomach is not a great idea. It’s the sort of thing you can do when you’re younger, and then at a certain point in your life it may start bothering you. I’ve heard this from a few others as they get into their 30’s. Try making sure you have a bit of food in your stomach.
