IBS and Coffee: Why Your Morning Routine Might Be Sabotaging You

You’re in good company if you’re a coffee drinker. An estimated 73% of people drink coffee, and 36% of people drink as many as 5 cups a day. 

Coffee might be a beloved pick-me-up, but for many with irritable bowel syndrome (IBS), it could be doing more harm than good.

Read on as Dr. Patel and his team explain how coffee can affect your gastrointestinal (GI) tract and how Bay Area Gastroenterology Associates, LLC, can help you find relief.

Learn more about IBS

IBS is a chronic digestive condition that affects your large intestine. Common symptoms include abdominal pain, bloating, gas, diarrhea, and constipation. 

Depending on whether you mostly experience diarrhea or constipation, you might refer to your IBS as IBS-D (for diarrhea) or IBS-C (for constipation).

If you experience both constipation and diarrhea, your subcategory of IBS is likely IBS-M (mixed), which is the most common subcategory of IBS. About 44% of people with IBS have IBS-M.

Knowing whether you have IBS-C, IBS-D, or IBS-M gives you a good indication of how coffee may affect you. Coffee can impact anyone with IBS, but especially those with IBS-D.

How coffee affects your digestive tract

Your morning cup of coffee can affect your digestive system in a couple of ways:

Coffee stimulates your colon

Coffee stimulates the colon and increases gastric acid production, which can speed up digestion. For someone without IBS, that may not cause any issues. But if you have IBS-D, coffee might lead to cramping, urgency, or loose stools shortly after drinking it.

Even decaf coffee contains compounds that stimulate the gut.

Your creamer and flavors could trigger your symptoms

The coffee itself isn’t always the problem. In some cases, what you add to your cup could be the problem. For example, milk, creamers, or sugar substitutes can trigger cramping and diarrhea.

Do you need to quit coffee?

Not necessarily. Some people with IBS tolerate small amounts of coffee just fine. But if you’re dealing with a flare-up or notice symptoms shortly after your morning brew, it might be time to experiment.

Try:

• Cutting back to one cup a day
• Switching to a low-acid or cold brew option
• Keeping a food and symptom journal to track patterns
• Testing alternatives like herbal tea

If you keep a food diary, don’t forget to write down any coffee add-ins — just in case your add-ins (like creamers) are triggering your symptoms rather than the coffee itself.

Choose gut-friendly mix-ins

If you're not ready to give up coffee, consider changing what you add to it. Artificial sweeteners — especially sugar alcohols like sorbitol and mannitol — are common IBS triggers because they’re poorly absorbed in the gut and can lead to bloating, gas, and cramping. 

Instead, try low-FODMAP alternatives, such as stevia or monk fruit extract, which are often easier on sensitive digestive systems.

Dairy-based creamers can also be a problem for those with lactose intolerance or IBS. Swap out dairy creamers for lactose-free milk or non-dairy alternatives like almond or oat milk (just be sure to check the label for added gums or sweeteners). Making these small swaps can help you enjoy your morning coffee without the unwanted symptoms.

Pro tip: Don’t try a new combination on a busy morning. Consider trying mix-ins on a morning when you don’t have to rush out the door.

Non-coffee ways to wake up in the morning

If you decide to forgo your morning cup of coffee to manage IBS symptoms, you’re not out of energy-boosting options. There are several IBS-friendly ways to start your day with clarity and focus — no caffeine required.

Begin with a glass of water and a squeeze of lemon to gently arouse your digestive system. (Citrus, like lemon, is lower in fructose and less likely to trigger IBS symptoms, but if you find that the lemon bothers you, skip it.) 

Light movement, such as stretching or a short morning walk, can increase circulation and help shake off grogginess. 

Try a high-protein, low-FODMAP breakfast, such as scrambled eggs with spinach or lactose-free Greek yogurt with chia seeds. 

Finally, natural light exposure — even just stepping outside for five minutes — can regulate your circadian rhythm and cue your body to feel more alert.
