Does Coffee Cause Bloating?

Does Coffee Cause Bloating?

Start your day with a cup of coffee—isn't that the ritual for many? But does coffee cause bloating? This is a question that might not cross your mind until you find yourself feeling unexpectedly puffy.

While coffee is a cherished morning kickstarter, it's important to explore how it might affect your digestive health.

In this article, we'll uncover how coffee consumption can contribute to bloating. So, before you reach for your next cup, let's uncover the brew-tiful connection between coffee and your gut.

How does coffee contribute to bloating?

Various factors contribute to coffee-induced bloating, including additives, excessive intake, dehydration, and acidity.

While it's true that coffee can cause bloating, it only affects certain individuals. A study found not all, but some caffeine-sensitive folks get discomfort from coffee.

Here's how coffee can contribute to bloating:

  • Gut-brain link: Coffee may activate the gut-brain axis , potentially contributing to bloating. This effect is still under study, requiring further research for a complete understanding.


  • Too much coffee: Drinking a lot of caffeine can upset your stomach.This can lead to symptoms like heartburn, acid reflux, and bloating. Best to keep caffeine under 400 mg a day to dodge bad effects.


  • Additives: Ingredients like milk, cream, and sugar in coffee can contribute to bloating, especially for individuals with lactose intolerance or sensitivity to certain sugars. Artificial sweeteners may also cause fermentation in the gut, leading to gas and bloating.


  • Acidity: The natural acidity in coffee, stemming from the brewing method and chlorogenic acid, may worsen digestive problems like acid reflux and symptoms of irritable bowel syndrome (IBS), causing bloating and discomfort. If you experience these issues, adding probiotics to your daily routine might be helpful. To alleviate these issues, try The Good Bug's Acidity Aid for relief. This product contains a diverse blend of probiotics designed to provide additional relief. 


  • Release of hormones: Drinking coffee triggers the release of hormones like gastrin and cholecystokinin (CCK), affecting the gastrocolic reflex and potentially causing bloating, abdominal pain, and diarrhea, especially in individuals with digestive conditions like IBS.


  • FODMAP sensitivity: Certain types of coffee, when combined with milk or specific creamers, can become high in FODMAPs, causing discomfort for individuals sensitive to these sugars. Choose low-FODMAP creamers and sweeteners to cut down on bloat.


  • Gut microbiome disruption: Excessive coffee consumption or strong brews may disrupt the gut microbiome balance, leading to gastrointestinal issues including bloating.


  • Sweetener sensitivity: Artificial sweeteners or sugar substitutes in coffee, including sugar alcohols and natural sweeteners, may trigger gas and bloating, especially for those with digestive conditions like IBS.


  • Combination with bloat-inducing foods: Mixing coffee with bloaty foods like cruciferous veggies, beans, or dairy can worsen bloat.

The Effects of different types of coffee on bloating

Not all coffee is created equal when it comes to its impact on bloating. Different types of coffee, as well as the brewing methods and additives used, can have varying effects on digestive health.

For instance, black coffee, without any additives, tends to be more acidic and can potentially lead to more bloating. Dark roasts and cold brew methods generally produce coffee with lower acidity, which might be easier on your stomach.Let's explore some of these differences:

Black coffee vs. decaf:

Black coffee

Black coffee is a widely recognized natural diuretic and is often consumed to alleviate bloating.

However, it's worth noting that if you're sensitive to caffeine, black coffee can actually contribute to bloating regardless of whether it's served black or with milk.

Drinking black coffee on an empty stomach can be particularly irritating to the gut. It may decrease the production of stomach acid needed for digestion, potentially leading to symptoms like abdominal pain, cramps, and bloating.

Black coffee is generally less likely to cause bloating compared to coffee with additives like cream or sugar, as these may contain lactose or other sugars that are difficult to digest.

However, black coffee's high acidity and caffeine content can still lead to bloating, particularly for those sensitive to acidic foods or with digestive conditions.


Decaf coffee, though lower in caffeine, still stimulates digestion and may cause discomfort in some individuals. 

Decaf coffee is still acidic, like regular coffee, and can diminish stomach acid levels, leading to similar digestive issues. It might be surprising, but decaffeinated coffee can also cause bloating.

This might seem counterintuitive since it lacks caffeine, but caffeine is not the sole component of coffee that can irritate the stomach and disrupt digestion. 

Therefore, if you're considering switching to decaf to avoid bloating, it may only be beneficial if your sensitivity is specifically to caffeine and not to other components of coffee.

Roasting and brewing methods:

Darker roast coffees are often less acidic, which can reduce the potential for irritation and bloating. Additionally, brewing methods like cold brew or French press can result in a smoother, less acidic cup of coffee.

Recommendations: If you're prone to bloating, it's generally recommended to opt for low-acid, dark roast coffees, and avoid excessive additives or sweeteners. Experimenting with different brewing methods and roasts can also help you identify which types of coffee your body tolerates best.

If you suspect that coffee is contributing to your bloating issues, it's worth trying a gradual reduction or elimination strategy. Replace coffee with herbal teas, water, or other non-caffeinated beverages, and observe if your bloating symptoms improve.

Does cutting out coffee reduce bloating?

If you suspect that coffee is contributing to your bloating, reducing your intake could help alleviate symptoms.

Experiment with cutting back and observe how your body responds. Alternatives like herbal tea or even chicory root coffee can provide a comforting hot beverage without the bloating effects.

Understanding the factors that contribute to coffee-induced bloating is the first step towards finding relief. For those seeking additional support, The Good Bug's Bye Bye Bloat will offer the helping hand your gut needs to deal with the irritation caused by coffee. 

Managing coffee-induced bloating and discomfort: Preventive measures

If you're looking to reduce your coffee intake or explore alternatives to manage bloating, here are some preventive measures and solutions to consider:

Explore coffee alternatives: Consider trying herbal teas or caffeine-free alternatives like chicory or dandelion root coffee.

Gradually reduce caffeine intake: Instead of quitting coffee, try gradually reducing your daily intake to minimize withdrawal symptoms and give your body time to adjust.

Increase physical activity: Regular exercise can improve digestion, reduce stress, and promote overall gut health.

Incorporate fiber-rich foods: Foods high in fiber, such as fruits, vegetables, and whole grains, can help regulate bowel movements and alleviate bloating.

Avoid gum and carbonated drinks: They can cause belly bloat by introducing excess air into your system. Instead, opt for low-acid alternatives like green tea or milder coffee blends to reduce strain on your stomach and inflammation. 

Consider moderation: Overindulging in coffee or choosing strong, hot brews may disrupt your gut microbiome, resulting in digestive issues. Consider moderation, adjusting your brewing method, or selecting low-acid options to alleviate bloating. Pay attention to additives and ensure you stay hydrated while maintaining a balanced diet rich in fiber and hydration.

Opt for low-acidity Coffee: Some coffee varieties, such as Arabica beans, naturally have lower acidity levels, which can be beneficial for those with sensitive stomachs. Additionally, the roasting process can impact acidity; darker roasts typically have lower acidity compared to lighter ones.

Watch your coffee additions: Sometimes, it's not the coffee itself but the additives that cause discomfort. Cream, sugar, or flavored syrups could be the culprits. Consider alternatives like almond or oat milk if lactose is an issue, or opt for natural sweeteners such as stevia or monk fruit.

Try decaf: If caffeine sensitivity triggers bloating, opting for decaffeinated black coffee could be a viable solution. It offers the taste of coffee with lower caffeine content. You can still enjoy the flavor of coffee without the potential digestive discomfort associated with caffeine.

Be mindful of your additives. If you typically add dairy or artificial sweeteners, consider switching to lactose-free alternatives like almond or oat milk, or try natural sweeteners. Alternatively, enjoy your coffee black to assess if it helps alleviate bloating.

Incorporate gut-friendly foods: Include probiotic-rich foods like yogurt and fermented vegetables in your diet to support a healthy gut microbiome.

Opt for dark roasts. Dark roast coffees are generally less acidic, potentially reducing the likelihood of stomach discomfort. If acidity is a concern, choosing a dark roast might help minimize bloating. 

Control your portion size: Consuming excessive amounts of coffee can heighten stomach acid production, leading to bloating. Experiment with reducing your coffee intake to see if it improves symptoms.

Practice stress management: Stress can exacerbate digestive issues, so incorporate relaxation techniques like deep breathing, meditation, or yoga into your routine.

Drink slowly: Rapid consumption of coffee can result in swallowing air, contributing to bloating. Take your time enjoying your black coffee to mitigate this risk.

Consider timing: Consuming black coffee on an empty stomach may increase acidity and bloating. Try having your coffee with or after a meal to lessen the impact of acid on your stomach.

Stay hydrated: Drink plenty of water throughout the day to help flush out excess gas and promote regular bowel movements.While black coffee is a diuretic, which may lead to increased urination, it can paradoxically cause your body to retain water to prevent dehydration, resulting in bloating.

Ensure you remain adequately hydrated to counteract this effect. Water-rich fruits and vegetables can help flush out excess gas and promote regular bowel

Listen to your body: Individual responses to coffee vary. Pay attention to how black coffee consumption affects you, considering factors like types of coffee, additives, and drinking habits. Adjustments based on these observations can help you enjoy coffee without discomfort.

Incorporate probiotics: Foods like kimchi  contain natural probiotics, which help balance gut bacteria and relieve bloating. Try adding them to your meals for digestive support.

Remember, managing bloating and maintaining gut health often requires a multi-faceted approach that combines dietary modifications, lifestyle adjustments, and, if necessary, professional guidance from healthcare experts.

Additionally, for individuals with sensitive stomachs or chronic bloating issues, it may be beneficial to consult with a healthcare professional or registered dietitian for personalized guidance and recommendations

It’s crucial to remember that everyone's body reacts differently, so personalization is key.

Incorporating water-soluble prebiotics and probiotics from The Good Bug into your routine, along with careful monitoring of your coffee consumption, can make a significant difference in your digestive wellbeing.

By addressing any digestive issues, you can enjoy your morning brew without the discomfort of bloating.

If you continue to experience persistent bloating or other digestive concerns, it's advisable to consult with a healthcare professional for personalized guidance.
