Does Coffee Cause Bloating? Research and Tips

Does Coffee Cause Bloating?

Bloating is a common complaint among many people, especially those with irritable bowel syndrome (IBS). That uncomfortable sensation of fullness, pressure, and abdominal distension can leave you feeling miserable. But what actually causes bloating? And is coffee one of the culprits?

For those with IBS, identifying trigger foods and drinks is an important part of managing symptoms. While coffee is often blamed for contributing to bloating, the research on this popular beverage is mixed.

Coffee and Gastrointestinal Issues

Coffee contains a number of compounds that have the potential to aggravate the digestive system, especially when consumed in excess. These include:

• Caffeine - This central nervous system stimulant found naturally in coffee can stimulate gastric acid secretion and colonic motor activity which may cause diarrhea or loose stools in some people.
• Gastric acids - Coffee is thought to promote increased gastric acid production which could worsen heartburn.
• Polyphenols - These plant compounds in coffee may loosen stools.

So while coffee does contain substances associated with gastrointestinal distress, whether or not it contributes specifically to bloating is debatable.

Coffee and Bloating - What Does the Research Say?

Over the years, a number of studies have aimed to analyze the effects of coffee on bloating and other digestive symptoms:

• A 2012 study published in Gut looked at the dietary habits of 1,005 IBS patients. While some dietary restrictions helped ease certain symptoms, restricting coffee intake did not ease bloating.
• A 2013 study in Clinical Gastroenterology and Hepatology found that for patients with diarrhea-predominant IBS, coffee restriction provided no symptom relief compared to a normal diet.
• A 2016 study in Nutrients observed that higher intake of coffee was associated with reduced constipation among U.S. health professionals studied.

While some people do report bloating as a side effect of coffee, the research suggests that coffee may not be directly causative in most cases. So what might explain this disconnect?

Why Might Coffee Lead to Bloating for Some People?

If coffee itself may not independently cause bloating, why do some people adamantly claim it leaves them bloated and gassy? There are a few possible reasons:

1. The caffeine stimulating effect - For those sensitive, coffee's stimulating effects could potentially trigger other gastrointestinal symptoms like diarrhea that indirectly cause temporary abdominal distension.
2. Added ingredients - Things added to coffee like milk, cream, artificial sweeteners, etc. may be the actual bloating culprits for some people.
3. Overconsumption - Consuming more caffeine than your body can comfortably tolerate might cause anxiety, jitters, and hypersensitivity to normal body sensations that could be perceived as bloating.
4. The body's individual response - We all have unique digestive systems and responses to foods and beverages. Coffee may just be an intolerable trigger for some.

Tips for Dealing with Coffee-Related Bloating

If you feel sure your morning coffee ritual is leading to unpleasant aftereffects like bloating, here are some tips to consider:

• Cut back on caffeine - Try gradually reducing your intake to see if a lower caffeine dose improves your symptoms.
• Change how you drink your coffee - Removing additions like sweeteners, milk, creamers, etc. can simplify the beverage.
• Consider decaf - Switching to decaffeinated coffee may help if caffeine is the culprit.
• Stick to one cup - Restrict your coffee drinking to just a single morning cup to prevent overconsumption.
• Allow caffeine breaks - Abstaining from all caffeine for set periods can reset your tolerance.

Making notes about what you drink and any associated symptoms can uncover useful connections to guide your adjustments.

Other Common Beverage Bloating Culprits

While the jury is still out on coffee as a direct bloating offender, there are certainly other drinks that tend to spell trouble for sensitive stomachs. These include:

Carbonated Beverages

The bubbles in carbonated drinks like soda, sparkling water, beer, etc. can cause gassiness that leads to bloating, especially if consumed quickly. Even small amounts may trigger abdominal discomfort in some people.

Juices

Fruit juices are high in fructose, a natural sugar that can be rapidly fermented by gut bacteria causing gas and bloating. Apple, pear, cherry and prune juices tend to be high gas producers.

Alcohol

Happy hour drinks are another problematic option if bloating troubles you. Alcohol can irritate the stomach lining and spark an inflammatory response. Plus, carbonated alcoholic beverages have a double whammy effect which can worsen that bloated feeling.

Milk and Dairy

Lactose intolerance is prevalent, with estimates that 65 percent of the global population has difficulty digesting milk sugars. Consuming dairy products can lead to bloating, gas and diarrhea in lactose malabsorbers.

Sweetened Drinks

Beverages like flavored coffees, fruit smoothies, slushies, frappes and milkshakes taste heavenly but can wreak havoc on sensitive digestive systems. The high sugar feeds gas-causing gut bacteria and causes abdominal expansion.

The Best Anti-Bloating Drinks

Fortunately, there are many delicious bloat-busting beverages to still enjoy. Hydrating choices free from compounds that tend to trigger digestive distress include:

• Water - Plain or sparkling water is generally well tolerated and helps flush out your system.
• Herbal tea - Soothing teas like chamomile, peppermint, ginger or fennel can ease stomach discomfort.
• Low-acid juices - Some fruit juices like blueberry, cranberry or grape are gentler options.
• Kefir - This fermented milk drink is 99 percent lactose-free and rich in beneficial probiotics.
• Vegetable juice - Low gas-producing veggies like carrots, celery, parsley or spinach make great anti-bloating juices.

Paying attention to your own unique triggers is key to banishing belly bloat. An elimination diet can help identify problematic foods and drinks. Journaling symptoms and intake along the way provides useful clues to tailor your optimal anti-bloating diet.
