Coffee may not cause bloating in everyone, but it may be an indirect trigger for some individuals. Coffee stimulates peristaltic contractions which increase stomach acid production resulting in digestive symptoms like bloating.
If you suffer from frequent bloating, it may be beneficial to limit or switch to low-acid alternatives of coffee such as cold brew – it contains less acidity than its regular counterpart.
Does Coffee Cause Bloating?
Coffee can cause bloating due to acidity, caffeine, and additives like cream or sweeteners.
However, not everyone experiences bloating from coffee. It may be beneficial to keep a food diary and experiment with different triggers to identify the cause. Those sensitive to caffeine may try decaf or limit coffee intake.
Caffeine

If you are sensitive to caffeine, found in coffee, it may affect your digestive system and cause bloating. Caffeine stimulates stomach acid production which pushes food through without being digested properly, leading to bloat, gas or abdominal pain.
Caffeine can also act as a natural diuretic, flushing out excess fluid weight from your system and helping reduce bloating and fluid retention in many people.
However, this is not always the case: for some individuals it can cause them to bloat as soon as they drink their first cup of the day due to its often mixed with dairy, causing lactose intolerance sufferers bloat while consumption of dairy products can still cause disruption of digestion and result in bloating and cramping.
Acidity
Coffee is naturally acidic, which can irritate the lining of your stomach and cause discomfort in the form of gas and bloating. This is particularly true when consumed on an empty stomach or when combined with dairy products that have an affinity for producing similar effects.
Not all acidic foods cause bloat and acidity issues; eating non-acidic fruits and vegetables such as bananas, melons, apples and pears may help ease both.
Cold brewing methods may also help lower the acidity of coffee. By chilling water for up to 24 hours prior to brewing, a cup of cold brew coffee produced is approximately 70% less acidic than traditional hot brewed. Give this method a try to see if it helps ease bloat symptoms!
Dairy
While coffee may help improve gut motility and diversify internal bacteria, too much may overstimulate the stomach lining when taken on an empty stomach, leading to gas and bloating symptoms for some individuals.
Additionally, many people like to add milk or sugar to their morning cup of joe. Unfortunately, this can also contribute to bloating as many individuals have difficulty digesting lactose; when this dairy does not break down properly it creates extra gasses which lead to extra gassiness in the colon and additional gaseous emissions.
However, bloating can be eased through subtle adjustments to your daily habits. Start by keeping a food diary to monitor everything you eat or drink – including coffee – including probiotic-rich foods and supplements as possible triggers of bloat. Be sure to drink enough fluids while decreasing stress levels to further ease bloat symptoms.
Excess Water
Bloating can occur for numerous reasons, depending on factors like gut health and food sensitivities. When it comes to coffee specifically, however, bloating could result from dairy in full-fat cow’s milk (if lactose intolerant) or from sugar or artificial sweeteners used as sweeteners in add-ins.
Diuretic properties of caffeine may lead to excessive water retention and hard stools for some individuals, potentially leading to bloating as well as hard stools. If this is causing issues for you, try limiting or switching out for nondairy alternatives for optimal results.
Food journals can help identify any correlations between digestive discomfort and what you consume and any subsequent bloat-causing foods, and your gut flora.
A registered dietitian may offer personalized recommendations based on symptoms and diet history to reduce post-coffee bloat quickly. In fact, drinking a glass of water as soon as coffee consumption begins can often provide relief immediately!
What Are Some Other Foods or Drinks That Can Cause Bloating
Bloating can be caused by various foods and drinks, including:
Beans, peas, and lentils can sometimes cause bloating due to the presence of oligosaccharides. These sugars can be challenging for the body to break down efficiently.
vegetables, such as broccoli, cauliflower, and cabbage, contain a type of sugar called raffinose. This particular sugar has the tendency to produce gas in the body and cause bloating.
Carbonated beverages, such as soda and sparkling water, contain significant amounts of carbon dioxide gas. This gas can lead to feelings of bloating in some individuals.
Dairy products like milk, cheese, and other similar items can lead to bloating in individuals who have lactose intolerance or sensitivity towards lactose.
Artificial sweeteners, such as sorbitol or aspartame, present in certain foods and drinks, can lead to bloating due to their challenging digestibility by the body. Some fruits like apples, watermelon, and grapes contain fructose. In individuals sensitive to it, fructose can lead to bloating.
Onions and garlic – these culinary staples are known for their aromatic flavors. However, they contain fructans, a type of carbohydrate that can lead to bloating sensations in some people.
Grains such as wheat and barley contain a protein called gluten. This protein can cause bloating in individuals with celiac disease or gluten sensitivity.
If individuals frequently experience bloating after eating, it can be beneficial for them to maintain a food diary. By conducting experiments with different triggers, they can identify the underlying cause of their bloating. In case of sensitivity towards certain foods, it might be advisable to regulate or completely avoid their intake.

How Can You Reduce Bloating Caused by Coffee
Drinking water is crucial after consuming coffee to alleviate bloating. Hydration plays a vital role in preventing excessive water retention, which contributes to bloating. Alongside sipping water between coffee servings, maintaining overall hydration levels is essential when indulging in coffee.
Reducing coffee intake can help alleviate bloating instead of completely eliminating it. Consider either reducing your consumption or switching to decaf coffee as a possible solution.
To support healthy digestion and reduce bloating, consider incorporating gut-friendly foods and drinks into your diet. An effective example is asparagus, known for its fast bloat reduction capabilities.
Supplements can be beneficial if you’re familiar with your body. They are available to support your coffee habit and address specific concerns, such as dairy sensitivities or excess gas production. By incorporating the right supplement, you may reduce any discomfort and worries related to bloating.
Additives like cream, sugar, and artificial sweeteners (such as sorbitol or aspartame) should be avoided because they can cause bloating. The body has difficulty digesting these additives, which leads to discomfort.
It is noteworthy that what may be effective for one individual might not yield the same results for another. If an individual experiences persistent bloating subsequent to consuming coffee, maintaining a food diary and experimenting with different triggers could prove beneficial in pinpointing the root cause of their discomfort.
However, if the bloating becomes severe or is accompanied by additional symptoms, it would be advisable to seek guidance from a medical professional or healthcare practitioner.
Is There a Difference in Bloating Between Regular and Decaf Coffee
There is no significant difference between regular and decaf coffee in causing bloating. Both contain caffeine, which can stimulate the digestive system, leading to gas production and discomfort. Decaf coffee still contains coffee acids and additives, potentially upsetting your stomach.
However, due to lower caffeine content, decaf coffee may be less likely to cause irritability or negative digestive effects. It’s important to note individual variations, so keep a food diary and experiment with triggers to identify the cause of persistent bloating after drinking coffee.
