Do you get sick after drinking coffee? Here are the causes and solutions! 

Because coffee refluxes and irritates the stomach, it can make you feel sick. Due to its acidity and potential for dehydration, coffee can make you feel sick.

Caffeine is a fairly potent substance. Focus, vigor, performance, even the quality of sleep, can all be aided. However, caffeine does have some drawbacks that most people are unaware of until they experience them firsthand. For example, frequent caffeine side effects include nausea and headaches.

But what if I told you that these symptoms could be easily fixed ? Continue reading for advice on how to stop feeling nauseous after drinking coffee.

Why Do I Feel Sick After Drinking Coffee?


Science is the answer to everything. Coffee’s acidity, which, according to Trista Best, a registered dietician and professor of nutrition, can range from 4.5 to 5.5 in terms of pH, is one common cause of feeling queasy after drinking it. “This can lead to gastrointestinal discomfort, nausea, and reflux,” Best says.

Since caffeine is a stimulant, it encourages the digestive system to function a little more quickly, including producing more stomach acid than is necessary. “Stimulating the stomach, especially when it’s empty and can quickly absorb the caffeine, can cause nausea,” Dietitian Diana Gariglio-Clelland of Balance One explains. “The gastroesophageal sphincter, the opening at the base of the esophagus through which food passes into the stomach, is also loosened by it.” This sphincter can relax and allow some stomach acid to leak into the esophagus, which can lead to acid reflux, heartburn, and nausea.

Diuretic Effects

While nausea and acid reflux are both unpleasant, some people also experience the laxative effects of caffeine. Because caffeine is a diuretic, it encourages the expulsion of water from your body in one way or another. “A diuretic causes water to be drawn from the blood and into the digestive system,” Lisa Richards nutritionist and author of The Candida Diet, says, “which can result in nausea or diarrhoea.”

Milk & Sweeteners

It may also depend on how you’re drinking it if you feel like these two aspects of the situation don’t adequately explain why you feel queasy after consuming coffee. Sweetener and milk added? Both have the potential to upset your stomach and make you feel queasy.

If you notice that you feel particularly ill after a milky coffee, you may be lactose intolerant. Artificial sweeteners can disrupt your gut’s natural microbiome, adding to the discomfort of your poor acid-filled tum. If you have any worries or queries regarding your symptoms, it’s important to talk to your doctor.

How to Prevent Feeling Nauseous After Coffee

The reason why you don’t always feel queasy after drinking your morning cup of coffee has to do with those acids.

Consider Switching to Decaf

If you’re feeling sick after drinking coffee, it’s probably because you’re sensitive to the caffeine. Heartburn, anxiety, and stomach upset are all possible side effects of caffeine. Your sleep cycle may be affected by it as well. Try switching to decaf if you’re having trouble avoiding the after-coffee sickness.

Compared to regular coffee, decaf coffee contains significantly less caffeine, making it less likely to upset your stomach or interfere with your sleep.

You might also try consuming a banana before or right after your coffee. The effects of caffeine on your body can be lessened by eating bananas, which are a good source of dietary potassium.

Switch the Roast

Try darker coffee roasts as an alternative. Darker roasts are typically less acidic than lighter roasts and may be easier on your stomach. Contrary to popular belief, lighter roasts contain more caffeine. Due to the roaster’s lighter touch, more caffeine is retained in the product. Longer roasting times result in darker roasts that have lost some of their caffeine content.

Switch How to Take It

Try drinking it black if you’re currently consuming it with cream and it’s giving you the flu. The addition of milk or cream can help make coffee more tolerable if you already drink it black and it makes you queasy or sick.

You can also try cutting the coffee with some unsweetened milk substitute, a scoop of collagen peptides and a natural sweetener instead.

Drink Coffee With a Meal

Having coffee with food can help you stay healthy. This is because drinking coffee on an empty stomach can result in digestive issues. Prior to drinking coffee, consider eating something. Even a small snack like a pastry or some crackers can keep the stomach healthy. Consequently, if you’re feeling queasy, try consuming coffee with a meal.

Drink Smaller Amounts of Caffeine Throughout the Day

Since caffeine is a stimulant, consuming too much of it can have negative effects. Drinking small amounts of coffee throughout the day as opposed to a lot at once will help you avoid feeling sick. Aside from taking breaks to walk around and practice deep breathing, make sure to stay hydrated by drinking plenty of water. A visit to the emergency room is advised if symptoms continue.

Limit the Number of Cups of Coffee You Have Per Day

Small amounts of coffee are typically beneficial, but too much caffeine can cause nausea and other unpleasant side effects. It’s critical to consume no more caffeine than is safe for you each day. It is generally accepted that 400 mg is the upper limit for those who are feeling sick. Drink plenty of water to flush the caffeine from your system if you’ve exceeded your limit. If you’re feeling sick or have a low caffeine tolerance, stay away from coffee.

Drink Caffeine-free Beverages

If you do begin to experience symptoms of an impending heart attack, stop drinking coffee right away and take deep breaths until they subside. Most of the time, there is no lasting harm to the person.

Stay Hydrated

Coffee can make you feel sick if you consume it on an empty stomach. Therefore, it’s crucial to drink water first. You should consume at least 8 glasses of water each day to stay healthy. Coffee won’t replace the need for electrolytes and water. Therefore, you should drink something to restore the electrolyte balance if you want to avoid dehydration. To avoid becoming dehydrated, sip on milkshakes, juice, Gatorade, or smoothies.
