For many of us, coffee is an essential part of our daily routine. We rely on it to wake us up in the morning, to get us through a long day at work, and to provide a much-needed energy boost when we’re feeling tired. However, for some people, coffee can have an unexpected and unpleasant side effect: it can make them feel upset. If you’re one of the many people who experience anxiety, jitteriness, or an upset stomach after drinking coffee, you may be wondering why this is happening and what you can do to avoid it.
The Science Behind Coffee’s Effects on the Body
To understand why coffee can make some people feel upset, it’s helpful to look at the science behind how it affects the body. Coffee contains a number of different compounds, including caffeine, polyphenols, and acids, which can all have different effects on the body.
Caffeine: The Main Culprit
Caffeine is the most well-known and widely studied compound in coffee. It’s a stimulant that can help increase alertness and energy by blocking the action of adenosine, a chemical that makes us feel tired. However, caffeine can also have negative effects, particularly in large doses. It can cause anxiety, jitteriness, and an increase in heart rate and blood pressure.
How Caffeine Affects the Brain
When caffeine enters the brain, it binds to adenosine receptors, blocking the action of adenosine and increasing the activity of other neurotransmitters like dopamine and norepinephrine. This can lead to feelings of alertness and energy, but it can also cause anxiety and jitteriness in some people.
How Caffeine Affects the Body
In addition to its effects on the brain, caffeine can also have negative effects on the body. It can cause an increase in heart rate and blood pressure, which can be problematic for people with pre-existing heart conditions. It can also cause stomach upset, including nausea, vomiting, and diarrhea, particularly when consumed in large amounts.
Other Compounds in Coffee That Can Cause Upset
While caffeine is the main culprit behind coffee’s negative effects, other compounds in coffee can also contribute to feelings of upset.
Polyphenols: The Good and the Bad
Polyphenols are a type of antioxidant found in coffee that can have both positive and negative effects on the body. On the one hand, polyphenols can help protect against cell damage and reduce inflammation. On the other hand, they can also cause stomach upset and interact with certain medications.
How Polyphenols Affect the Body
Polyphenols can affect the body in a number of different ways. They can help reduce inflammation and improve cardiovascular health, but they can also cause stomach upset and interact with certain medications. For example, polyphenols can inhibit the activity of certain enzymes, which can affect the way the body metabolizes certain medications.
Acids: The Hidden Culprit
Acids are another compound found in coffee that can contribute to feelings of upset. Coffee contains a number of different acids, including citric acid, malic acid, and quinic acid, which can all cause stomach upset and heartburn.
How Acids Affect the Body
Acids can affect the body in a number of different ways. They can cause stomach upset and heartburn, particularly when consumed in large amounts. They can also interact with certain medications and exacerbate conditions like acid reflux.
Why Some People Are More Sensitive to Coffee’s Effects
While anyone can experience negative effects from coffee, some people are more sensitive to its effects than others. There are a number of different factors that can contribute to this sensitivity, including genetics, body weight, and overall health.
Genetics: The Role of Genetic Variation
Genetic variation can play a significant role in how sensitive we are to coffee’s effects. Some people may be more sensitive to caffeine due to genetic variations that affect the way the body metabolizes it. For example, people with a variation in the CYP1A2 gene may be more sensitive to caffeine’s effects.
How Genetic Variation Affects Caffeine Metabolism
Genetic variation can affect the way the body metabolizes caffeine. People with a variation in the CYP1A2 gene may metabolize caffeine more slowly, which can lead to higher levels of caffeine in the body and increased sensitivity to its effects.
Body Weight: The Role of Body Size
Body weight can also play a role in how sensitive we are to coffee’s effects. People who are smaller or have a lower body mass index (BMI) may be more sensitive to caffeine’s effects due to their smaller body size.
How Body Weight Affects Caffeine Sensitivity
Body weight can affect caffeine sensitivity by affecting the way the body metabolizes caffeine. People who are smaller or have a lower BMI may metabolize caffeine more slowly, which can lead to higher levels of caffeine in the body and increased sensitivity to its effects.
What You Can Do to Avoid Coffee’s Negative Effects

Choose a Low-Acid Coffee
If you experience stomach upset or heartburn from coffee, you may want to try a low-acid coffee. Low-acid coffees are made from beans that have been processed to remove some of the acidic compounds.
How to Choose a Low-Acid Coffee
To choose a low-acid coffee, look for beans that have been processed using a method that removes some of the acidic compounds. You can also try a coffee that has been blended with other beans to reduce its acidity.
Avoid Adding Large Amounts of Sugar or Cream
Adding large amounts of sugar or cream to your coffee can increase its calorie content and contribute to weight gain and other health problems.
How to Healthily Add Sugar or Cream to Your Coffee
If you like to add sugar or cream to your coffee, try using a small amount (1-2 teaspoons of sugar or 1-2 tablespoons of cream) and choose a natural sweetener like stevia or honey.
Conclusion
Coffee can be a delicious and energizing beverage, but it can also have negative effects on the body. By understanding the science behind coffee’s effects and taking steps to avoid its negative side effects, you can enjoy coffee in a way that’s healthy and sustainable for you. Whether you’re sensitive to coffee’s effects or just looking for ways to make your coffee habit healthier, there are a number of things you can do to enjoy coffee without the negative side effects.
What are the common symptoms of coffee upset?
The common symptoms of coffee upset include stomach upset, nausea, heartburn, acid reflux, and diarrhea. These symptoms can range from mild to severe and may vary from person to person. Some people may experience only one or two symptoms, while others may experience a combination of several.
The symptoms of coffee upset can be uncomfortable and may interfere with daily activities. In some cases, they can also be a sign of an underlying condition, such as acid reflux disease or stomach ulcers. If you experience persistent or severe symptoms, it is essential to consult with a healthcare professional for proper diagnosis and treatment.
Why does coffee cause stomach upset in some people?
Coffee can cause stomach upset in some people due to its high acidity and caffeine content. The acidity in coffee can irritate the stomach lining, leading to heartburn, acid reflux, and stomach pain. Caffeine, on the other hand, can stimulate the stomach muscles, causing them to contract and leading to nausea, vomiting, and diarrhea.
Additionally, coffee can also slow down digestion, allowing stomach acid to build up and cause discomfort. Some people may be more sensitive to the acidity and caffeine in coffee, making them more prone to stomach upset. Factors such as individual tolerance, coffee brewing method, and additives like sugar and cream can also play a role in coffee-related stomach upset.
